I have a hard drive that someone disconnected without safely removing it and now the computer is telling me I need to format it before I can use it and that it is RAW.

I went to CMD and ran chkdsk I: /f (As another post suggested) and it told me that it can't check it since the drive is RAW. I'm not sure on what I should do next... any help?

It's giving me the error that says

"Data error (Cyclic Redundancy Check)."

The drive is Toshiba MK3265GSX 320GB.

You may want to see a few of these other threads I responded to as I think the tools I mention there could help:

mswindows-forum/windows-won-start-ntldr-missing-t105642.html#p585593

hardware/sata-hard-drive-not-showing-t105704.html

Hope that might help you.

It didn't work... the drive isn't writable, it doesn't find any partitions...

For me TestDisk didn't find any partitions either until I corrected the problem with the Disk Geometry being wrong. What I would suggest is figuring out the correct Disk Geometry for your hard drive. Typically if you take your hard drive out of the computer it will say the proper values to use on it. If it does not, then look up the exact model of the hard drive and find the values. Then go in the Geometry section of TestDisk and try putting them as the right values. For me once I put in the right values, then my partition came back and all of my files.

For me this all happened when my computer crashed, it must have messed up how the geometry was specified for my hard drive, which basically made everything unreadable, including the partition. For my situation once I fixed those values I was able to gain access to my hard drive again.

Woah o.k now your going to need to give me something to read about that like really i just had a 1tb drive crash on me and the computer won't boot or function with it connected.

i was going to try the 3.5 sata to a external case and see if i can not get in that way but i may need to look into this testdisk while i do that too.

nice post

Oh, thanks for bringing this thread back up zealous... I completely forgot about it...

About the Disk Geometry... the Hard Drive has the following information about it:

Quote:
8455MB (CYL16383,H16,S63)
320GB(LBA 625,142,448SAectors)

From that, I think it reads:

Sectors: 625,142,448
Heads: 16
Sector Size: ??
Cylinders: 16,383

Am I missing something?


Also, TestDisk is telling me that the drive has read error on every sector...
