I have a machine with a 3 disk raid 5 set. One of the disks has developed bad sectors in the parity block (I'm assuming it is in the block because badblocks /dev/hdb shows bad areas, badblocks /dev/md0 does not), which causes it to randomly get kicked out of the set. I got a drive to replace it with today. It's not the exact same model, but it's the same physical dimentions (C/H/S & capasity are identical). It's just a little faster than the others, with a little more cache on the drive. But when I repalce the bad drive with the good drive, I get invalid arguments when trying to bring up the array. I don't get it. There is a perfectly valid linux partition on the drive, /dev/hdb1 which meeds the same specs as /dev/hdc1 and /dev/hdd1, but replacing hdb with a drive showing no bad blocks won't work.
Help?
The existing drives are IBM DTLA-305020 drives, and my replacemt is a DTLA-307020. Both show their physical dimentions as:
Capasity: 20.5GB CHS: 16383/16/63
