boot messages mount: wrong fs type

[ved]

when i restart the system get error messages
Mounting local filesystems: 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 [FAILED]

It sounds like something has either corrupted /dev/sda1 or the device names have changed (possible of you added/removed a disc). To check, boot from a liveCd or recovery disc and run the command: fdisk -l

In the case when something has reordered the device names you can fix that by changing /etc/fstab to use either labels or UUIDs instead of /dev/sd..

i solved this problem first delete this portion then get free space about 48 GB then i creat it again then and formate as ext3 file system then now i got only 41GB space what about 7GB SPACE ?



THANKS

Post the output of fdisk -l command here.

[Rubberman]

If it was some type other than ext3 before, such as ext2, then some of the missing space is due to transaction logging requirements - ext3 is a transaction-oriented logging database. That makes it more reliable from the context of recovery after a system crash, power failure, etc.

Partition table entries are not in disk order

[devils casper]

That's a incorrect partition table. Look at start/end cylinders of each partition. /dev/sda2 and sda3 are overlapping and device name sda2 has been assigned to first partition.

I would suggest you to backup data, if any and recreate partition table from scratch.

Edit : Just now I noticed that you have installed Linux OS in this Hard disk. Could you post the contents of its /etc/fstab file here?

what i have to do i just send the details of fstab
