dd on entire disk, but do not want empty portion
- by Jonathan Henson
I have a disk, say /dev/sda.
Here is fdisk -l:
Disk /dev/sda: 64.0 GB, 64023257088 bytes
255 heads, 63 sectors/track, 7783 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0000e4b5

Partition 1 does not end on cylinder boundary.

I need to make an image to store on our file server for use in flashing other devices we are manufacturing so I only want the used space (only about 4gb). I want to keep the mbr etc... as this device should be boot ready as soon as the copy is finished.
Any ideas? I previously had been using dd if=/dev/sda of=[//fileserver/file], but at that time, my master copy was on a 4gb flash ide.
