[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.
