Mounting partition problem
Hi folks,
Have a newly partitioned HD with following config;
root@ttyp0[knoppix]# fdisk -l
Code:
Disk /dev/hda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 77 514080 82 Linux swap
/dev/hda3 78 1415 10747485 83 Linux
/dev/hda4 1416 4865 27712125 5 Extended
/dev/hda5 1416 2510 8795556 83 Linux
/dev/hda6 2511 3485 7831656 83 Linux
/dev/hda7 3486 4216 5871726 83 Linux
/dev/hda8 4217 4865 5213061 83 Linux
without OS installed.
/dev/hda5, /hda6/, hda7 and /hda8 all have data files. All partitions can be mouted previously on running Knoppix 4.0 LiveCD.
with "mount /dev/hdax /mnt/hdax" as Root and mounting on deskop on their icons as User.
An hour before ran Knoppix 4.0 to browse Internets and have some files saved on /dev/hda8. Those files were not download on Internet. Just copied some text/information from Internet on existing files on /dev/hda8. The PC/Knoppix LiveCD worked without problem and was turned off later.
Now after turning on the PC and starting Knoppix LiveCD it was found /dev/hda8 could not be mounted.
root@ttyp0[knoppix]# mount /dev/hda8 /mnt/hda8
Code:
mount: wrong fs type, bad option, bad superblock on /dev/hda8,
or too many mounted file systems
Other partitions can be mouted without problem. The data/files on them can be read.
root@0[knoppix]# e2fsck -f /dev/hda8
Code:
e2fsck 1.38 (30-Jun-2005)
e2fsck: Filesystem revision too high while trying to open /dev/hda8
The filesystem revision is apparently too high for this version of e2fsck.
(Or the filesystem superblock is corrupt)
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
Whether to run "e2fsck -b 8193 /dev/hda8" to clean it.
I think the problem was caused by adding some information to a file on /dev/hda8. I opened the file as USER. After adding some information to it I tried saving it back to /dev/hda8 but not allowed. Then I saved it to /home/knoppix/tmp/new_file_name. Started a console, "su" Root and moved to file to /dev/hda8. I tried this trick before without problem.
Is it possible to backup the files on /dev/hda8? I have 3~4 important files on this partition which I expect to reserve if possible.
Please advise how to fix this problem.
TIA
B.R.
