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 ============================================================= 1st action: 33 megs was from /dev/sda to a file. 2nd action: 1.3 MB from /dev/sda to a file 3rd action: 1.2 MB from a file to /dev/sda So he backed up 1.3 MB to a file, then overwrote 1.2MB. So restoring 1.2MB of that original backup will restore that part of /dev/sda to it's previous status. Jacques B.
