[minoukat]

Thanks

MS's fdisk progs(excluding the one's included with NT and Win2K--maybe)aren't sophisticated, but they get the job done. As far as DOS/FAT16/FAT32 go, anyway.

I think, but I'm not certain that Logical DOS drives can only exist within an Extended DOS Partition. The Extended DOS Partition must be created first.

Fdisk can create non-MS partitions. But they aren't "typed," which they must be before they can be used by say...Sun Solaris 8 or Linux. This is where Linux's version of fdisk comes in mighty handy! It can create partitions and type them for ~80 different OS's. Including FAT12/16/32. I've used Linux's fdisk program to partition HDD's that will only be used for Win OS's. It's a much more logical program to use than MS's version of fdisk!

You can only have two partitions on a physical hard drive in Windows. The primary and extended. The logical drives are one or more "drives" you specify within the extended partition. A logical drive appears to the OS as a physical drive.

Just an example, say you wanted three partitions on a single HD that are all equal size. You would create the primary with 1/3 of the disk space. Then create the extended partition using the entire remaining space. Then you create two logical drives within the extended each using 50% of the available size which leaves you with 3 final partitions each using 1/3 of the drive size.

The term logical drives also can refer to muliple drives that are used as one drive. If you were running 6 drives in RAID 5 through a controller, they would be set as a logical drive, or more than one drive if you chose to partition the set.
