I even tried to make a copy a the same hard drive and mount them together but still unable to mount. So I was unable to make a backup of my data from that hard drive. What I did was: I installed Fedora into another hard drive 120 gb and I mounted the 8 gb hard drive which recognized right away as sda6. 8 gb Hard drive with Fedora has type ext3 I was able to move my data from hard drive 8 gb to 120 gb But the problem is when I tried to transfer back my data from hard drive 120 gb to 8 gb and after that I was unable to launch the 8 gb anymore It says: fscl.ext2: Filesystem has unsupported feature(s) (/dev/hda6) w2fsck: Get a newer version of e2fsck! Fedora still recognizes the hard drive 8 gb but I can't use my data with Fedora The Software Needs to be run on Mandrake because I don't know the one who installed the software and how to transfer the software into Fedora or whichever operating system which can both launch my Software and make backups I suspect that Fedora use ext3 type and when it writes on the 8 gb hard drive it changed something which made Mandrake unable to recognize hda6 anymore Is there a way to fix that error? I need an answer quick because I use the software everyday and my job will be delayed. Thank you very much for your answer. Best regards.

If so, you can boot to a command line, then before you mount the drive, you can run fsck on /dev/hda1 to repair the file system. The ext2 and ext3 file systems are basically the same (in terms of inodes, directory structures, metadata, etc.) but ext3 adds journalling for better reliability. What messed up the drive was that fedora thought it was an ext3 system and probably wrote some metadata or journal info to the drive which mandrake doesn't recognize. - - - In the future, when you want to copy files from your fedora disc to the mandrake one, you need to manually mount the mandrake partition as an ext2 system. It should handle the older structure without problems, but you MUST run fsck on the file system first, and that has to be done when the drive is unmounted. Ok?
