For non raid drives all I ever have to do is umount the drives partitons. Once that is successful the drive can be removed. However, if you have smartctl running, it will start to complain until you put the drive back in. Or you could restart smartctl with the drive removed.

With raid drives I user mdadm to first fail the partitions on the drive to be remove/replaced, if they haven't failed already. (Use cat /proc/mdstat to see current status of all raid drives.)

Then use mdadm to remove those partitions from the raid drive. Then the drive can be removed/replaced.
