I personally have 10 partitions on my120 GB hard drive.
Off topic

Do not take this as Windows bashing, but Windows can only make 26 partitions normally (letters of the alphabet). That would imply not using any floppy, cd-rom or other device.

Actually Windows can only make 23 partitions. One primary and one extended that can have 22 logical
C: is primary
A: is dedicated to floppy
B: is dedicated to floppy(how stupid is that)
D: would be the extended that holds all the logical

B: comes from the time you booted your OS from the floppy, that's why there were several floppy drives...

As mentioned before - an extended partition still goes as a primary one

. If you don't have a floppy, is the drive letter still assigned to it? AFAIK, the primary partition that is extended, is not using any drive letter whatsoever. In PartitionMagic 8, it was always marked with * instead of D:\...

So, it would be 63 partitions per drive.
I used cfdisk to create as many partitions as I could on a spare hard drive. this is the output of fdisk -l after doing that.

Code:

gentoo wizard7 # fdisk -l
