I am unable to mount hard disk and got this message:

Unable to mount 158 GB Filesystem
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try dmesg | tail or so

From the terminal, I tried syslog - try:

No command 'syslog' found, did you mean:
Command 'dsyslog' from package 'dsyslog' (universe)
Command 'syslogd' from package 'sysklogd' (universe)
Command 'syslogd' from package 'inetutils-syslogd' (universe)
Command 'syslogd' from package 'busybox-syslogd' (universe)
syslog: command not found

Also tried dmesg | tail:

[ 971.390632] Read-error on swap-device (8:0:308424896)

It was fine before I tried to re-install 12.04 from the live CD (which failed due to the disk problem).
