Do you have any important files on it? Can you access it?

 

[Arif Hassan]

No, i have no important file on that drive and i am unable to access it it says you need to format the disk before using it.

I get that and have to format then in my Linux computer and then they work fine ? with 7 cant do nothing with them at all don't know if it a bug or a proprietary thing ..

after formatting them in Linux they will work as expected back on windows like nothing was wrong issue free to start with ?? go figure

one thing i wonder if you can make a bootable linux dvd and boot to it if it would be able to format the drive under the bootable dvd at its desktop ?? have not tried that being i got linux fully loaded on a harddrive

I get several pen drives that act this way

Okay. Please follow the instructions EXACTLY as shown:

1)Open Command Prompt by pressing ctrl+r at the same time. Type CMD and press Enter.
2)Type "diskpart", then press Enter.
3)Next, type "list disk" and press enter. If that fails to list the affected disk, try "list volume". It will NOT change your speaker volume.
4)Now, type " clear disk X:, replacing X: with the affected drive. Again, you may need the " clear volume X:" command, replacing X: with the affected volume. CHECK 4 TIMES TO ENSURE YOU HAVE SELECTED THE RIGHT DISK,VOLUME!!!!!!!!! ALL DATA ON THE DISK/VOLUME WILL BE DESTROYED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
If "clear disk X:" or "clear volume X" doesn't work, you can try "clean disk X" or "clean volume X". This takes MUCH longer. Like hours longer on 1TB drives.
If that works, you can start using the USB stick again, but DO NOT trust it with important data EVER! Hope that helps!

i tried step 3 still does not find the hard drive. computer management find it. but cant initialize crc error
I tried using hard disk sentinel,
health is 100%
performance 100%
The hard disk status is PERFECT. Problematic or weak sectors were not found and there are no spin up or data transfer errors. No actions needed.

CRC error? Can't initialize? Post #5 won't fix that. See if your storage medium manufacturer can fix that. Sorry.

stick it in a Linux rig or a xp / vista -- windows 7 is the only os so far I get this with my pen drives .. you can look online them steps compgee showed most times never work out anyway on 7

good luck
