[root at frodo ~]# sfdisk -l /dev/sdc
Disk /dev/sdc: 38913 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes,
counting from 0
Device Boot Start End #cyls #blocks Id System
/dev/sdc1 * 0+ 254 255- 2048256 c W95 FAT32 (LBA)
/dev/sdc2 255 38912 38658 310520385 83 Linux
/dev/sdc3 0 - 0 0 0 Empty
/dev/sdc4 0 - 0 0 0 Empty
** I note that the file system on /dev/sdc2 is 'Linux' and not
'Linux LVM'. This is what I got, eventhough I created it with
parted /dev/sdc mkpart ...
[root at frodo ~]# dd if=/dev/sdc2 of=/dev/null
12747056+0 records in
12747056+0 records out
** The above output is after letting dd running for few minutes;
after that I killed the process because I was afraid it will take
it too long.
Thank you for your help,
