If you don't have hot swap drive bays:
- Power off your computer
- Fit the new drive in the chassis and plug it into a free SATA port
- Boot your computer again
If you do have hot swap drive bays:
- Insert the new drive into a spare drive slot
Then:
- cat /proc/partitions to see what new partitions have appeared
- check /var/log/syslog and dmesg to see what new drives have been
seen
Most likely the partitions from the new drive just appear and can be
mounted somewhere, put in /etc/fstab and so on.
A possible failure mode is that your computer reorders its drives
and the new one becomes sda. This may interfere with your boot
process. Hopefully you referred to everything by UUID or label so
that this doesn't happen. If it does cause problems just take the
new drive out again and things should return to normal. Then you may
have to consider swapping cables between ports, or adjusting BIOS
boot order, or similar.
Most of the time though, just plugging the new drive in goes fine.
Cheers,
Andy
