Hi Andreas,

Tks for your advice.

This partition is about 5~6G, if I recall correctly.  Which number
shall I use to test.  

Besides do I need to backup this partition before test?  Partition
/dev/hda7 has about 5.6G space available.
# mount /mnt/hda7
# df -hT /mnt/hda7
Filesystem    Type    Size  Used Avail Use% Mounted on
/UNIONFS/dev/hda7
              ext3    5.6G   33M  5.3G   1% /mnt/hda7

Would running
# dd if=/dev/hda8 of=/dev/hda7

backup its content to /dev/hda7.  Please advise.  TIA

Remark: there are several non-important working files on /dev/hda7.  To
overwrite them has no problem.  The data on /dev/hda8 is about 900MB
