Hi Gordon,
Further to my late email, I performed following test on hardware
Hard disc
# fdisk -l
Disk /dev/hda: 255 heads, 63 sectors, 4865 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 2433 19543041 7 HPFS/NTFS
/dev/hda2 2434 4865 19535040 f Win95 Ext'd (LBA)
/dev/hda5 4156 4865 5703043+ b Win95 FAT32
/dev/hda6 2434 4089 13301757 83 Linux
/dev/hda7 4090 4154 522081 82 Linux swap
Remark: /dev/hda6 ext3
1)
# e2fsck -c /dev/hda6
e2fsck 1.23, 15-Aug-2001 for EXT2 FS 0.5b, 95/08/09
/dev/hda6 is mounted.
WARNING!!! Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.
Do you really want to continue (y/n)? (no)
2)
# e2fsck -c /dev/hda
e2fsck 1.23, 15-Aug-2001 for EXT2 FS 0.5b, 95/08/09
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/hda
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>
CD-Writer
1) Without CD in CDWriter
e2fsck -c /dev/cdrom
e2fsck 1.23, 15-Aug-2001 for EXT2 FS 0.5b, 95/08/09
e2fsck: Read-only file system while trying to open /dev/cdrom
Disk write-protected; use the -n option to do a read-only
check of the device.
2) With CD in CDWriter
[root@localhost dev]# e2fsck -c /dev/cdrom
e2fsck 1.23, 15-Aug-2001 for EXT2 FS 0.5b, 95/08/09
/dev/cdrom is mounted.
WARNING!!! Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.
Do you really want to continue (y/n)? (no)
What will be the proper commands to check
1) hard disc
2) Video card
3) cdrom
4) cdwriter
Thanks in advance.
B.R.
Stephen
