hdb1 and hdb3 are primary ext3... and hdb2 extended
i add them to /etc/fstab and mount to /mnt/hdb1 , /mnt/hdb2, /mnt/hdb3
i succestful mount it...

after i reboot, error occured.

fsck.ext3: attemp to read block from filesystem resulted in short

Could you show us the content of /etc/fstab and the output from 'fdisk -l' ?

Second time using this answer today - must be a FAQ now. To mount the root partition read/write in maintenance mode
Code: Select all
mount -w -o remount /
. You should then be able to edit /etc/fstab and comment out the problematic entries.

The information toracat requested is essential to go any further. You might also want to run
Code: Select all
fdisk /dev/hdb
v

to verify the partition table. The extended partition is usually the last one. You may have overlapping entries.
