how to check file system?

[pom]

I surely surely hope someone knows the answer of my question.

I have to HDDs on my desktop, old smaller drive with all my files is fedora core 2
and the new big drive just installed fedora core 13. I think they have the same file system but I can not mount the big drive when boot using the first drive using
mount -t ext3 /dev/sdb2 /media/800GB gave error wrong file system
same as ext4.

info about my two disks are

Disk /dev/sda: 250.0 GB, 250000000000 bytes
255 heads, 63 sectors/track, 30394 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
