WD External USB HD removed without ejecting. HD NO ACCESS

#1 Post by EdTomchin »

I have a WD 1TB My Passport External USB HD which is nearly full. I unplugged the USB without first "ejecting" the device. Now I get a "WD Hardware Error USB Device" when trying to access the data on the HD.

I am running Windows 7 SP1 64bit on a PC. When I used Computer Management I get an error message saying "Disk 2 Unknown, Not initialized." When I tried to initialize the HD I recieved another error message saying "The request could not be performed because of an I/O device error."

I called WD and even though the HD was out of warrranty, they listened to my problem and told me the only way I could recover the 400+ movies on this HD was to use data recovery software. I checked with TechSupportAlert, a dependable newsletter I receive and looked for some good data recovery software. You were recommended. I'd like to know if your software can deal with this issue. I don't care about the HD itself. I can get another one. But the movies were ripped from DVDs I no longer have and I'd like to recover the data. I hope you can help me.

Thank you.

Since W2k, didks must be initialized that windows can work with.
It means, as long as your disk is not initialized you'll have no partition table.
Also I/O device error often points to a defective disk?
As long as your disk management console displays the disk size correctly you can run testdisk / Analyse and Quick Search to have a try to find your partition by the boot sector of your previous partition.
I assume your file system has been NTFS?
If nothing would be found, you can run Deeper Search also to have a try to find your partition by the backup of the boot sector which is located at the end of your lost partition.
If a partition would be found, you can select it and press p to have a try to list your files.
When your files are listed, you can use testdisk to copy your data to another healthy disk or partition.
