Based on your comments about drive naming (sdX) ... you're using software
RAID.
I've never had problems with smartd keeping a hold on a drive ... anyways
When I remove drives from a server running software RAID, I remove the
drive from the SCSI subsystem. That way the new drive gets the same drive
name/block device when inserted and detected. The docs you're looking for
are [0] and [1].
I've included an example of mine below. If I've misunderstood you, please
clarify.
Here's an example from my past notes:
mdadm /dev/md0 -f /dev/sdb3 -r /dev/sdb3
# do the same hot-fail/hot-remove for partitions 1 and 2 from their array
cat /proc/scsi/scsi
echo 1 > /sys/block/dev/sdb/device/delete
echo "0 1 0" > /sys/class/scsi_host/host0/scan
sfdisk -d /dev/sda | sfdisk /dev/sdb
mdadm /dev/md0 -a /dev/sdb3
# do the same hot-add for partitions 1 and 2 to their array
watch -n1 cat /proc/mdstat
