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.

What commands do you exactly type and what error messages do you
exactly get?
