Corrupt FAT system on external hard drive?

have you tried right mouse click on it - properties-tools and try the options in tools

hope it helps

As long as the disk is recognised in the BIOS then try this

Boot into Windows, check the drive letter of the External drive (e.g. drive F:) even if you can't access the drive contents but can see the drive this should work.

Go to Programs > Accessories > Command Prompt (if using Vista or W7 right click and select run as Administrator)

When the black window pops up type chkdsk F: /r / f and press enter

(F: assumes this is the correct drive letter, if different then obviously adjust it)

this may fix the issue.

If not you can try again, this time use the following

F: fixboot

when finished reboot and you can also try

F: fixmbr

but only if the drive contents have not appeared

Failing that you may as well format the drive.

You could try it in a different machine, but it probably won't work

Running a Linux live CD has a better chance of reading it

Try this one

Pick 'vesa' for the graphics mode and look at the mounted drives at the bottom

An external drive will probably be named SDB(number) rather than SDA(number) which will be internal drives and partitions

Unfortunately i have bad news for you. If the file system is indeed corrupt you have no other option. ou can try getting someone who does data recovery if the data is very important to you but that costs alot of money

when you connect try these steps

start

run

cmd

type chkdsk (drive letter:) e.g if its the e: yuo would type chkdsk e: and keep doing this process a few times as it might work but is very unlikely and the best thing is to format Im afraid :(

hello,

try to repair fat table using a dedicated software like "Acronis disk director".
