I am trying to put together a raid1 configuration using two drives one of which is 200g and the other is 250g. I have one using the whole drive ending on cylinder 23241 and then created two partitions on the second, one ending at 23241 also and the other taking up the rest of the drive.

First off, should I even be trying this with two different drives (the only physical difference according to hdparm is a buffer of 8MB on one and 2MB on t'other)?

Secondly, and my problem now, is that mdadm stalls at 21.9% and slowly brings the computer to a freeze while doing a resync. Can anyone help me?
