This is interesting. I took hdd and put it on hdb and did this: dd if=/dev/hda of=/dev/hdb which took over 5 hours as I went to bed. It was done this am.

I guess my question is what really controls the CHS layout of a disk? (Nate mentioned firmware in a recent post.)The dd in this command obviously changed the hdb drive's CHS layout.
Or reconnecting the drives reset what the bios/drive reports. I've seen this happen just reciently with some serial ATA drives without using dd.
