Bad superblock when mounting hard drive...
i was writing data to one of my hard drives and the program crashed (amule). i rebooted my machine as it was running slow and now it wont mount my hard drive..... i get an error message saying
"unable to mount /dev/hdf1 : Can't read superblock"
now as im a bit of a n00b when it comes to linux i dont know what to do... on some of the other threads ive searched it said to do a file system check, but when im in a console it says "fsck :command not found"
this is all on Mandrake 10.1 community edition btw.
any help that can be given would be great... would like to get the 150gb of data back...
You have corruptions on your disk, the best way to check it is by booting into your mandrake cd (install disk) and using the utilities on there to check it. So, once you have booted the mandrake cd, press CTRL+ALT+F2 (F1 - F6 are your text mode terminals and should all be useable, I just always go for F2, or F6 if F2 is not available). From there you should be able to log in as root, type in "man fsck" and get the manual page. If you can't get the man page then just try "fsck" and you should see a "usage" message.
First of all you need to know or find out where your corrupt partition(s) is(are), run something like "fsck -y /dev/hda1" (where hda1 is the first partition of hda (usually "C" in windows) and -y means fix automatically (generally safe)). Try different combinations of hda, hdb, hdc and hdd - hda# is the most likely though (primary master disk).
Bad superblocks can be recovered but I have only ever had to do that with "ufs" on solaris machines, you most likely use ext2, ext3 or reiserfs.
Ah, fsck can't scan a fat32 filesystem, you will need to scan it under windows (using scandisk). If windows isn't installed then you can always plop your hard disk into a machine that does run windows, then scan it.
