A redhat 9 linux system had 2 drives, /hda and /hdb. Then /hda started developing bad clusters {UncorrectableError}, so I got an identical warranty replacement drive. Then I hooked up the new drive as /hdc, and did a sector by sector copy {dd if=/dev/hda of=/dev/hdc conv=noerror,sync} Overall, I got ~2k of bad 512B sectors. Then I swaped the fresh one to /hda, and put aside the failing one. I booted, did fsck on all partitions and also raids, and things came up fine. So far so good. Now I am trying to add the failing one as /hdc, and boot. Linux starts to display all kinds of weird messages, and thinks that / partition was shut down uncleanly. I just hit "reset". Then I disable /hdc via the boot option hdc=noprobe, and things boot fine. If I try to disable raid via raid=noautodetect, the bunch of errors still appears and the boot is no go. Done this several times, without /hdc things are fine, with - all kinds of issues. What is the problem for linux to boot on /hda when /hdc is detected and has almost identical setup? Where does it read all the garbage that starts to screw up the boot process when /hdc is detected? I'd like to hook up /hdc to wipe out the data there. The drive is huge, so I'd rather wipe it out while working then under other circumstances. Thanks! Konstantin __________________________________ Do you Yahoo!? Yahoo!
