My USB disk drive is not accessible. Help!

[account_disabled]

Hi guys,



I urgently need your help! I have about 50GB of data on my hard disk drive and I can't access it. I ran some anti virus checks with no luck. My operating system is Windows 7.



The message was initially that the disk needs to be formatted in order to be accessed but obviously I don't want to lose my data.

Then the disk becomes readable and then again non-readable so I can't make a back up of my data. I also tried Properties > Tools > Check now but no positive result there either.



Then again I read some forums and tried the chkdsk /F /R /X H: command (as an admin). The message got from cmd was:

The type of the file system is RAW.

CHKDSK is not available for RAW drives.



I also tried chkdsk H: /R and got the message:

The type of the file system is FAT32.

Cannot read boot sector.



I really don't know what else I can do.

Thank You!!!

I didn't find the right solution from the Internet.
