Re: Help with a little dd damage!

Hi Folks

This post could equally be titled - is there a God?

Yesterday I ran this command:
[root@morgansmachine DiskBUImagesEtc]# dd if=/dev/sda of=pocketpc.rescue bs=1M count=33
(No output, just bash history.)

Today I ran these commands:
[root@morgansmachine DiskBUImagesEtc]# dd if=/dev/sda of=2ndstage.rescue bs=1K count=1280
1280+0 records in
1280+0 records out
1310720 bytes (1.3 MB) copied, 0.0535238 s, 24.5 MB/s
[root@morgansmachine DiskBUImagesEtc]# chown morgan: ./2ndstage.rescue
[root@morgansmachine DiskBUImagesEtc]# dd if=zImage-LAB-20060421.htc of=/dev/sda
2348+0 records in
2348+0 records out
1202176 bytes (1.2 MB) copied, 0.117155 s, 10.3 MB/s
[root@morgansmachine DiskBUImagesEtc]#

Both yesterday and today I should not have used /dev/sda, but should have used /dev/sdc... Ouch...

Now I seem to have an unallocated partition of some 37.26GB where once existed my carefully constructed laptop hard drive.

Everything seems to be running fine, but I expect if I reboot - I wont! I guess I've just wiped out my MBR or something close.

So, fingers firmly crossed, have I managed to copy enough of my hard drive with the first two commands to be able to patch back the catastrophic damage I seem to have done with the last command. Could someone more confident than I give me some instruction:)

Any help desperately welcome.

Since you made a backup, probably no problem:
dd if=./2ndstage.rescue of=/dev/sda count=2348
restore what you overwrote from what you saved.
