[dundee] Renaming an HDD

[Malcolm]

Morning all.

Is this possible?  I've two identical HDDs both with PCLinuxOS on them, 
one old version, one newer version.  This means the partitions are the 
same and I can't tell the discs apart

When looking at them with dolphin,  malcolm - home devices, they are 
listed by partition size, 216.9 GiB Hard Drive, and that's the bit I'd 
like to rename

Right clicking gives me an Add Entry option but I don't know what this 
does and don't want to break an unbroken thing.

If I can't rename them what other options have I got?  I've considered 
custom partitioning so the root partitions are different sizes.


TIA.
