Hey Guys, thanks for the reply about the block stuff...

So if I run the dd command(s) you gave I get this output below...

Up to 512-bytes:
Code:
# dd if=/dev/sdc bs=512 count=1 | od -c

All the way to 2048:

Is it safe to say here that the asterisks in the output above denote EMPTY space in that area of the disk..?

Also, so I'm clear on the sector/block size stuff.
If this below is the output for fdisk, and the START is 2048 and the UNIT size 512 bytes.
So for every "1 Unit" out of the 2048 START point, that would be: .5kb * 2048 = 1024 Kb... Is that right?
Code:
# fdisk -l /dev/sdc

Disk /dev/sdc: 7969 MB, 7969177600 bytes
255 heads, 63 sectors/track, 968 cylinders, total 15564800 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x5503c906

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1   *        2048      516099      257026   83  Linux
/dev/sdc2          518144    14554890     7018373+  83  Linux
/dev/sdc3        14555136    15550919      497892   82  Linux swap / Solaris

Thanks Again for the help, much appreciated!

Thanks,
Matt
