No, they actually mean total hard drive size (unformatted)
Drives have sectors, blocks, heads, and all sorts of other confusing other terms that only mean something to people with pocket protectors (unlike me.)
In order to partition a hard drive, the software must be able to talk to every block and sector within the drive.
I've not used partition magic is a couple years but it does a great job and did then.
Your drive has too many numbers for that version of PM to handle. It MAY work, but then again, it may only allow an 80 gig HDD and if you use it on your 120, then it may rewrite the boot sector so that you end up only being able to use 80 gig of your drive and you would have to repartition and reformat with something that could do it to such a large drive.
There are definite hardware cuts in drive size.
are hardware or logical cut offs in drive size, most of them are logical points where the software (BIOS usually) could only address a certain size drive.
