Hard Drive: File record segment is unreadable

I have a 80GB hard drive Seagate Barracuda just use it to store files (documents, images, videos, etc.). I always used as a slave or by or connected with a USB adapter.

In overnight stop loading the hard drive connects to a laptop or computer to another, as a slave ... and nothing. Bone and the bios if the system recognizes that there is a hard drive connected but will not let me go and see the files.

When you run Chkdsk I get the message ...

Quote:

xxx file record segment is unreadable

And so on for long.

I have proven with Winternals Erd Commander but is hanging when trying to access the drive. Already tried a Kubuntu Live CD and not let me access.

That got to read that with a low-level formatting the hard drive could be revived, but I do not want to lose my documents there, but are very important. Any idea how to recover? a tool that I have passed?

You can try the HDD Regenerator to repair bad sectors on your hard drive.

HDD Regenerator if you do not find any bad sectors, you can try to fix the mbr disk.

See if you are lucky.

sectors of the damaged disc, if not fix hdd reg say your files, the mbr has nothing to do, the low-level format (the truth) reduces the size of the disk as it does not get damaged sectors of the zero -fill (common but wrongly called low-level format) only remove the information from the hard disk full of zero sectors.
