I guess that means that /pgs is a real directory on /dev/sd0a then.

It needs to be in "/etc/fstab" to be mounted automagically at boot time,
this was obviously omitted for some reason during the install process,
but can easily be rectified now. Have a look at the output of the
'dmesg' command to double check that the 5th drive is detected
correctly, then edit '/etc/fstab' and add it! See 'man fstab' for more
help.

Sorry, yes '/dev/sd0a' mounted on '/' (a.k.a. root).

I'd be inclined to make both '/dev/sd0a' and '/dev/sd0s1e' about 100M.
