Hi everybody, I'm in a big trouble: I have a computer AMD 400Mhz K6(I know it's old) I use a hard drive 8 gb which has Mandrake 7.0, Kernel 2.2.14-15mdk /dev/hda6 on / type ext2 (rw) <= Data I need /dev/hda1 on /boot type ext2 (rw) But the thing is I can't mount with any other drive and I don't know the reason because I don't know who installed it. 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.
