ok so i got a Seagate� 500GB hard disk
model: Barracuda 7200.12 ST3500418AS
Im on a laptop and connecting the drives with a Manhattan hi-speed usb 2.0 to sata/ide adapter with power supply
I open disk management with either one of them plugged in, i can hear the disk is running and all, I see Disk1 appear on my disk manager screen... it says unknown and not initialized right on the left on the virtual disk manager
and when I open this screen, it prompts me to initialize the disk
It says:
"You must initialize a disk before Logical Disk Manager can access it."
I mark Disk1 and select Master Boot Record as partition style, and when I click OK, there's an error message saying "the device is not ready"
it worked before, it is actually brand-new.
The first time it was used I installed it and formatted on my laptop running windows 7 64bit, then I tried it on a Mac and it wasn't readable, so it was re-formatted (the guy who did it told me it should work on both mac and windows...
), still empty... now i have this problem, I don't know what I can do.
I have the exact same problem with another seagate� barracuda but this one is 500GB 7200.11 ST3500620AS, this one isn't brand-new, it was on a desktop mac.
pleasee someone help me, I hope I made myself clear, my english is not that good.

Hello erickegg69 Welcome to the Seven Forums!
From the screens you have there note the screen that actually follows the first when adding a new drive. That will provide the option for selecting a drive letter.
Before the first screen however look on the square section next to the main volume seen at the left side where it says "unknown". You first have to right click on that in order to turn the drive "online". Once that is done you can proceed to use the add new drive wizard and assign a drive letter.
Upon closing the wizard up you can then open any explorer window or Computer to see a new drive icon with the assigned drive letter you selected since the external drive will then have been initialized correctly.
For use on both Mac and Windows alike you would leave that drive as Fat32 but simply see the drive made active unless you no longer plan to use the drive on the other machine and strictly for Windows use. Once you reformatted the first older drive to NTFS it was no longer cross platform between the two OSs. This is why you had to reformat a second time back to Fat 32.

I'm sorry... when I right click on it the only options I get are Offline, which tells me the same "the device is not ready" msg, properties and uninstall.
I believe it is already online, so where can i open the New Drive Wizard?
thanks in advance

When you right click on the center portion to the right the new volume wizard as it is called will appear. The screens here will show how that looks since one should be familiar already. These were from a guide I made up while the last shows how to mark a volume as active in case that is needed there as well.
yeah the problem is that it doesn't initialize, it tells me device isn't ready and stays as is. i simply cant open the drive in My Computer, or format it from the disk manager screen, cause it stays as unknown and not initialized :S
The two things at the Seagate support site to look over are for new installation and previously working which seems to apply.
For new installation, External Hard Drive Troubleshooter for Windows 7 and Vista
For previously working, External Hard Drive Troubleshooter for Windows 7 and Vista
Those are for checking the drive's status in the Device Manager since you haven't been able to get anywhere in the DM as far as initializing the drive. If it was just bought and found defective I would simply say return for exchange or refund. But these will cover how it is seen in the device manager.

thank you for that, i followed instructions i now have my disk online in the disk management screen... now what do i have to do to be able to store data on it... (It still doesn't appear on My Computer as a drive)
and one more question ^^ should I make this a dynamic disk, or leave it as MBR?
Once it was seen online you simply go back into the Disk Management tool there to right click on the volume in order to select a drive letter. You may possibly see the new volume wizard come up. That be seen mainly for "raw" unpartitioned drives but Windows prompt you on formatting it if you skip past that.
Once a drive letter is set and you see a auto play popup showing it being searched by Windows with the option to view files you can look in Computer or Windows Explorer to see it present. The drive will have been initialized during right click to change drive letter or new volume wizard if seen.
You wouldn't need it turned into a dynamic volume since you are not running a server OS there. Most desktops and laptops alike 99% simply see a basic volume to begin with. The wizard will be mbr by default where you would simply go onto the next screen. Since this is an external not internal being used for storage and not seeing an OS you would only need to see the few basic steps there.
You'll be surprized how fast and easy it actually is once you have it set.

I have same problem with WD (Wester Digital) , 3Tb Essential.
Welcome to the Seven Forums! meem
I assume you are plugging the 3tb drive in by usb and not eSata port correct? You need to see the drive initialized by paying the Disk Management tool a visit. You can opt to bring down to bring down the Action menu and click the rescan if needed. (see attached image)
But once you spot the 3tb volume in the DM you simply right click on that to use the Change Drive Letter option. Windows will then detect and mount the volume on the drive as a new logical drive using the drive letter you select and be seen in Windows Explorer. Often you may also see a flashing popup notification that a new drive had been found as well.

Hi, i have exactly the same problem as erikegg69 but for my LaCie Hard Drive, Design by F.A. Porsche, and i can't find anything on the LaCie website. Anyone can help me? I tryed everything but it always say me that the "Device is not ready".

Hello Bieffe Welcome to the Seven Forums!
If you just bought the drive new and it shows Windows/Mac compatible it will see an exFat 32bit factory volume on the drive you can simply reformat to NTFS and then right click on the volume in the Disk Management tool to use the Change drive letter option. Other drives may come with NTFS factory volumes you might also want to nuke off of the drive in favor of simply seeing a new NTFS primary partition put on yourself instead.
Simply doing that one thing will immediately see the drive appear in Windows Explorer or Computer. What this does is initialize the drive or in the case of a usb flash drive or memory initialize the device. The information that comes along with the drive like a quick start pamplet would explain this to some extent.
The main reason for the immediate error has nothing to do with a defective drive or Windows glitch but just the need to get the dirive initialized in order to make it available for use.

It doesn't work because i just can't see the drive wherever i look for it in the disk management tool...
And thank you for the quick answer and the welcome word!
And thank you for the quick answer and the welcome word!
First you would need to look at the basic items since you are not seeing in the DM. If you simply forgot to turn it on... oops!
That happened to me when two ports on a usb hub simply gave out while having something charging by way of usb. I had forgotten that until nothing showed when turning the power on. Took a fast look to find the cord still unplugged and turned the enclosure off until plugged in.
Now if you haven't forgotten anything without realizing it and the drive is still not seen despite checking ac adapter at the wall outlet or back off drive casing, usb cord not only at the pc end but the end that plugs in at the drive end, and the on/off switch or button then you could be looking at either a bad drive if the casing has an led that comes on or a bad ac adapter if this was just bought where you can bring it back for refund or exchange.
While a bad drive should still allow it to be seen in at least the DM first before WE a totally dead drive is possible while nowhere near as likely as a DOA ac adapter! Or a contact inside the casing may have ended up with a cold solder point where the drive while enclosed there will never see power.
The "device is not ready" message definitely points to the drive being detected as an unknown device as Windows sees it but not available if the drive is not getting any power. In the Device Manager one idea besides looking under "disk drives" would be going to the menu bar>View to select the "show hidden devices" option there. If the drive is to be seen at all that would be the place to start unless you know the drive had been working before now.

Dear all, I'm new here.
I had the same problem about an External HDD. All the instructions didn't help.
BUT I discovered something else. I had the HDD connected to the USB on one of the screen USB connection. When I changed the USB connection direct to the Laptop the HDD worked, and I could read all data. So I think some of the USB deliver not enough power!

Welcome to SF! Kraems
Is your external drive self powered or usb powered? Most see an ac adapter so they won't pull on the usb bus. But some however are usb powered.
When starting up the laptop without the external HS plugged in and then plugging it in you should see a flashing popup as far as how the Auto Play settings in the Control Panel or need to simply take a trip into the Control Panel>Administrative Tools>Computer Management>Disk Management tool to simply scroll down to the new volume found there and right click to change the drive letter. Once you select a letter this will initialize the drive and see the volume on it mounted as a new logial drive in Windows Explorer with the flashing popup usually to open for viewing, etc.

Hello karthick Welcome o the Seven Forums!
When you go back into the Disk Management tool trying clicking to highlight the external drive and going upto the Action tab on the menu bar to see if the Rescan option will help. The next step if the All tasks>format option fails would be opening up a command prompt and type the following commands.
At the prompt type:
DiskPart = starts up the DiskPart partition manager
List Disk = all hard drives will be listed as Disk 0, Disk 1, Disk 2, etc.
Select Disk # depending on which will be found for that based on actual size
Clean = removes factory NTFS or exFat volume
Create Partition Primary = primary generally preferred over any extended volume even on storage drives
Format FS NTFS or Format FS=NT60 can be typed in lower case
Active = marks partition as active
Exit = closes DiskPart tool
If you see the sucessfully... type message you can close the command prompt and simply go back into the DM to right click and select which drive letter you want to have. You should then see the popup for new hardware found and possibly a prompt to scan the drive by the av program you are running.

they can see the DRIVE in the my computer but mine is completely different... i can't see the drive in my computer but it is detected ............ how can i solve this problem when i tried to put it in offline its showing "the media is write protected"....how can i solve it.....................
One option would be to boot from a live cd like Partition Wizard or GParted to run the format option while no Windows processes or even some 3rd party app is trying to access the drive. This will also bypass any write protection since no OS is running.
If the drive has any software such the volume being exFat to see it mounted in Vista that may be one reason for the write protection error being seen. Vista lacks any Fat support while 7 saw it returned just for things like external hard drives and flash drives, memory cards where Fat may be the default file system present.
When having one WD drive external turning out to be a GP sata II model drive enclosed in the drive saw exFat and had a form of Readi-Boost app that would bring up an installer. The installer was needed for Vista not XP or 7! I simply cleaned the drive off totally while booted live from a GParted Live cd and put a brand new NTFS partition on it.
If you already tried using the DiskPart tool and still got nowhere as far as the wipe and clean ntfs partition created the live cd option would be the next step. If that still fails you could be looking at a bad drive needing to be replaced or simply returned. Or the factory Partition Table was corrupt when you bought the drive where a full wipe is needed.

Are you plugging into a USB 3.0 or 2.0 port? The images show the Disk Management prompting to select either the MBR(Master Boot Record) or GUID option in order to see the drive initialize. That's a normal prompt where you decide if you will ever want to make it bootable or simply see a new Partition Table created.
From there you should be able to create a new volume on the spot! Look over the images attached to see how that works.

You can use the snipping tool in the Start>Accessories to grab images if you want rather then the need to attach pdf files. But the first thing to look at would be in the Device Manager under storage devices to right click on the drive item you find there to see if Windows will automatically search for and install the controller driver needed for you.
Lately I had to coach someone else who received an external enclosure as a gift on how to debug a similar problem of seeing the necessary driver go on Vista not 7 however. Checking for updates manually and looking at the optional updates might see the update you need included there or running the Secunia Personal Software Inspector would be an alternate route to take to see this cleared up for you.

All programs and drivers are up to date. Still shown as unknown device and I can't even try to initialize it now. Will search for referenced coaching to vista issue and extenal. next step is to delete driver and reininstall driver?
Did that not change. Still cannot find specified file
Thanks for the tips.

Have you looked under Storage controllers? You should see the manufacturer's name listed right away. Once the drive is initialized provided it is working as it should then you should see it appear under the Disk drives.
With one external drive without it actually having problems but having the need for an extra drive during the 7 beta/RC days I simply pulled the drive out of the enclosure to install internally and called it a day. If there's a controller problem which doesn't seem so likely or you can extract the drive carefully long enough to connect it internally if there's no eSata option you would find out if the drive itself will work or need to be replaced.
Here that old 500gb external is now presently the internal storage drive on the old Vista case rather then putting it back into the factory not so well vented casing. I have a fan cooled enclosure for any external drives instead!

Verified all drivers up to date. If i open the enclosure I loose a 7 year warranty. USB 3.0 is the only external connection besides power on the Verbatim 2tb external drive.
I think I have the same problem. I bought a 1tb verbatim store n go external hard drive. I accidently broke the usb connector on the external harddrive and bought a new rocketfish enclosure to replace. I plug it into my laptop and it show the hard drive on the device manager but it can't be initialized or rename. please help .. pictures should show the problem i have .Thanks
There's no partition on it to be renamed. vunguyen27 Welcome to SF! by the way.
What you see there is a raw unpartitioned and formatted drive to start with not having seen even a factory volume for either NTFS or exFat. First the Partition Table and then the partition(s) to be seen have to be created as well as formatted before the drive can be made useable.
If both of these drives are 3.5" sized drives you wouldn't be able to install them internally for sure while the use of a live cd program like Partition Wizard or GParted simply to see if a live method is able to work with them would be a thought. The screens back in Post #23 show how to do it while in the Disk Management tool. Those were created after having wiped the drive shown there using the Clean command in the DiskPart tool.
That would be the other option seen in Windows by way of the command prompt to see a new volume created. You first need something on the drive(s) however before they can actually be initialized by simply right clicking on the new volume to select a drive letter. Then Windows will proceed to mount the volume as a new logical drive.
The reeason for suggesting a live cd however is to get past any OS problems or restrictions that could be getting in the way as far as using the simple option right seen right there in the DM tool. If the controllers are good on the external casing as well as the usb enclosure you should have any problem with partitioning either of the two.

@vunguyen27: there is no solution for this even my HDD got the same problem as yours i have tried all the possibilities but no use the media in that is damaged.....
One reason I suggested installing it internally for a 3.5" model would be on a desktop to find out if the drive itself or the controller is toast. Since one drive was placed into a separate enclosure but if still being seen in the DM that shows the drive itself is functional to a certain extend that is.
Some years I had one go belly up when you could read everything on the drive but could not write to it in any form. The write heads part was foobar! That drive wore out prematurely however rather then being a defective HD.
For anything external these days I simply slap a new drive into an enclosure rather then buying anything self contained models. That can help recover data from both ide and sata drives alike when an old case finally gives out.
For a not too pricey fan cooled enclosure some of the Acomdata models can be looked over at Newegg.com - Computer Hardware, AcomData, External Enclosures, SATA & IDE
That would be a consideration for you, erikegg69 over continuing to fuss with what seems like a bad controller. So far I've had one of the three models in use now for the last years and swapped drives in and out both ide and sata without one problem as long as the drive was still working.
I could have opted for one seeing an eSata connection but had to go univeral here since I seem to be the one looking after Vista and 7 laptops as well as XP, Vista, and 7 desktops.

thank you night hawk for your instructions.
all completed successfully but still the hard drive fails to show up as a drive in mycomputer.
what should i do?

I would start looking at the usb port you are using as well as the cable the drive came with and port on the external enclosure as a possible cause. If you have a bad port on the system or enclosure which is always possible or a bad cord needing to be replaced that will stall the works! Often the enclosures use the same type of cord as the usb cable for a printer noting the smaller square shaped connector on one end.
Once you can rule any possible usb problem removing the drive from the enclosure to install internally especially if you are running on a desktop there to see if the drive itself is good or bad. This will isolate the drive itself from everything else.
If it partitions and formats on the spot then you would know the problem is simply tracing it back to a connector or port or even bad controller on the enclosure itself. But if it still fails to see working results then you will know the drive is foobar and should return it for exchange or refund if you had just bought it.

i have got the similar problem with my wd(1 tb). it is showing up in disk management and devices and printers but not in my computer. when i try to initialise the disk in disk management, it says the request could not be performed because of an I/O device error. please tell me how to get it work again...
Hello MukulSharma Welcome to SF!
The next time you are in the Disk Management look for the square section at the beginning of the volume for the external drive there. Right click on that to see if you can change it from offline to online. Then go upto the menu bar>Actions to select the rescan option before a right click on the volume itself to use the Change drive letter option.
Sometimes a new drive plugged in or installed internally even will be in the offline status. Once that is back online a rescan will let Windows know it is. From there you simply assign a drive letter to get it going and appear in WE.
The other thing to do in the Device Manager while not generally needed would be looking for any "other devices" usually being the mass storage controller wasn't detected and installed automatically by Windows as it should have been since WD drives are Plug'n'Play to start with. The driver install needs a little push at times to get that going.

i am not getting the option for getting it online. please have a look at the attachments. these are the options i am getting in device manager and disk management. also rescanning disk is not helping.
i did get the option to initialize the disk earlier, but i don't know why m not getting it now. bt even on selecting the option for initializing, it just said that the request could not be performed because of an I/O device error. and now if i select the offline option, then again it says the same thing.. I/O device error...
Likely the first thing you will need to do there is see a Partition Table created. The DM shows the drive is actually online but lacking what it needs! By right clicking in the volume area you may see the prompt for this.
Is this on a WD Eseentials or newer model series? On the Essentials those are shipped with exFat volumes to be Windows/Mac compatible. The Windows only models will ship with NTFS or be found "raw". With self contained drives generally a factory volume would be present however.
The external enclosure is being reported but not the drive itself apparently. You may received a bad drive. The fact that the enclosure is online indicates the mass storage controller is showing up. This is why I suggested taking a look in the Device Manager there to see if the usb enclosure item is present.
During 7 beta and RC testing I actually followed one guide to remove the drive itself to run it internally. But the drive was seen immediately when first plugged in new with the factory partition on it.

Hi dellstudio 1234,
Welcome to SevenForums.
An I/O device error and CRC errors on an external HDD mostly point to a failing/failed hard drive.
Since you had indicated that you tried diskpart clean all, I presume that you are not keen to recover anything from your ext. HDD.
Try the following:
1. Change the cable to the HDD and check.
2. Try the HDD on another computer with the new cable. If the same problem persists then it is certain that your system has nothing to do with this error and points to a faulty HDD.
3. Run the manufacturer's diagnostic/repair utility. If it cannot repair, go for a warranty return ( if within warranty).
4. Not to leave it to any chance, download HDD-LLF-Low-Level-Format-Tool ( the Windows executable that requires no installation) and Run it as administrator on the external HDD. If it can detect your HDD, it will try to do the same job as diskpart-clean all. You will see a running dialog that will indicate if it encounters any errors. If it successfully reinitialises the external HDD - which may take quite sometime - you have to format it - but I am skeptical. It is just to satisfy yourself that you have done everything possible.
This article is worth reading. Good Luck.

I wouldn't make it a habit to be using the "Clean All" command! When in DiskPart and you have selected the correct drive simply enter the clean command. If you enter the clean all command at the wrong time that will wipe more then one drive!
The DiskPart tool being the built in partition mahager showing a large error definitely isn't good! And I would tend to agree with jumanji that the drive could be history!
The WD support tools would be the Data Lifeguard tools available at the WD support site. You will first need to select the model series of the external drive you have there however starting with the main support page for Downloads Select Product
The guide for testing a drive is seen at How to test a drive for problems using Data Lifeguard Diagnostics for Windows

Select Disk 2(or correct actual number for drive)
clean
create partition primary(could be logical or extended as the alternatives)
format fs ntfs quick(alternate command format fs=nt60)
assign
exit
Once you enter those commands in in that order and you still don't get anywhere then you know there's a hardware problem for sure. It might be only the usb cable or the controller card in the drive's casing and not the drive at all.
The one sure way to find out if the drive is toast would be removing it entirely from the casing to either toss in another external enclosure or install internally and direct off the board from a sata port. I did that back in 2009 when needing an extra drive for testing 7.
I have the same problem with an external 3tb drive that was working fine. This morning the computer locked up and after a re-boot the drive was could not be seen at all listed in "computer"
In "disk management" it shows "drive 2" but will not initialize, now it will not even give that option. A right click only says "offline, Properties, and help". Properties does say the device is working correctly.
"diskpart" "list" command only shows disk 0 and disk1. However if I use "select disk 2" it will say "disk 2 is now the selected disk". Anything after that I get an error message.
I have tried plugging into other computers, no luck. Tried several recovery programs, none of them can "see" the disk.
I am guessing the file system is corrupt. Is there a way to recover this without deleting all info on the disk????
Please help.
Thanks!!!
