Hi,
Thank you all.
Looks like I forgot to run "mkfs.ext3 /dev/sdb1" after I used
"fdisk /dev/sdb" to partitioned it. originally this disk has many linux
partitions, after I repartitioned it to a single one, then reboot, it
automatically mounted as 9.2G disk. then I copied some 5.3G data onto
it.
The following is what I have just done, seems ok now.(although claimed
160G disk only has 140G can be use , too bad :) )
