When try to mount .

# mount -t ext3 /dev/sdc /tmp/temp
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
or too many mounted file systems

#mount /dev/sdc /tmp/temp
mount: you must specify the filesystem type

Could advise how to mount it back ? thx

You sure that the filesystem type is ext3?
What if you mount with ext2 option instead?

You made the filesystems on the disk? Did you run the mke2fs command to make the filesystem? Need to have a filesystem made before mounting.

When you use the mke2fs command, you supply the -j switch to make it a journal filesystem, ext3.

By default the filesystems are ext2.

Which partition of disk sdc are you wanting to mount?

mount /dev/sdc10 /tmp/temp

What happens when you mount without the -t switch?

Is there an entry in the /etc/fstab for what you are doing?

the below is the error , no entry in /etc/fstab . thx

mount /dev/sdc1 /tmp/temp
mount: error while guessing filesystem type
mount: you must specify the filesystem type

mount -t ext2 /dev/sdc1 /tmp/temp
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
or too many mounted file systems
(aren't you trying to mount an extended partition,
instead of some logical partition inside?)

You are trying to mount the wrong device. The /dev/sdc is the disk, and you must specify a partition number, like /dev/sdc1, /dev/sdc2, that's why you have the error.

Use fdisk -l to list the partitions.

post a copy of your /etc/fstab file, the df -k output, and the fdisk -l output.
