dd command and HDD drive problem ?
I am trying to copy my 80GB harddrive to a 320GB harddrive (i.e clone it to a larger HDD drive)
Because I am running out of space on the 80 GB drive so I just want to have this system on a bigger drive.
I have used dd if=/dev/sda1 of=/dev/sda2 bs=512
After that had finished copying to the other drive I went and check if the first 80GB of the new harddrive was exact copy of the old 80GB harddrive.
Basically I just hashed compared the 2
dd if=/dev/sda2 bs=512 count=15625000 | md5sum
dd if=/dev/sda1 bs=512 count=15625000 | md5sum
both hashes where the same so the probablity that they are identical is almost 100% (for the first 80GB of the 320GB HDD)
But when I try to boot the 320GB drive it fails to do anything I just get at the BIOS screen
saying something like press F1 to continue or F2 to run to bios setup.
If you press F1 it either spites back out the same message or hangs with a cursor.
If I press F2 it brings me as usual to the bios/cmos config page where I can turn on and off settings. (note: I have tried almost every combination of settings I can think of that would effect the booting process none of them worked )
the 320GB HDD is Western Digital drive
is sata 16MB cache WD3200AAKS
I am using an old dell dimension 4600 computer
The 80GB pata harddrive came with the original dell computer
The motherboard supports 2 sata devices and I have tried both the master and slave sata ports on the motherboard no luck.
I know the sata ports are good because they worked with an other 500GB seagate sata drive I had lying around with an important linux distro that I cann't overlay for copying this 80GB HDD.
I don't see much difference in the two sata harddrives hardware wise.
But here is the spec's for the seagate 500GB that boots and works fine.
seagate 500GB Barracuda 7200.12
5v 0.72 A
Date Code:11154 Site Code WU
I am curious to know why it is not working and what can be done to fix this.
Also if your wondering why I am mixing sata with pata it is because I can buy sata for half the price of pata/ide hd drives.
So I bought this sata 320GB hdd thinking I could do the same thing that I did with the 500GB sata drive that I had purchased a few months prior.
If you need any more info like the bios version this dell dimension 4600 is running I would be more then happy to look up it up. Along with anything else needed.
I hope it doesn't come down to a bios update since this bios already has the usb boot ability and other things that I wouldn't want to lose.
BIOS updating is the last resort and I may even thing about getting another harddrive before this.
Thanks for any help
