"Hidden Partitions
The PART utility uses the same mechanisms as Partition Magic and GDISK (Ghost) to Hide and Unhide
partitions. These utilities typically add 10 hex to the DOS partition type code. Since all the DOS
partition type codes are less than 0F hex, this will always result in a type code between 10 hex and 1F
hex. Since no valid partition type codes currently exist between 10 hex and 1F hex (DOS or otherwise),
it can be assumed that any partition with such a type code is a hidden partition. DOS will simply ignore
partitions with type codes between 10 hex and 1F hex (since those types are undefined) and no drive
letter will be assigned. In order to return such a hidden partition to service, it is a simple matter to
subtract 10 hex from the type code and reboot."
What this tells us is some program is changing this table. Since Windows doesn't do that you have to find it.

I have a problem I cant get a handle on. I have installed a second HD and after partitoning, formatting, etc. the partitons change to Hidden after reboot.
I have used Partiton Magic, the PowerQuest version, Computer Management/Disk Management utility in XP Pro and still I have the same problem.
Is there any help out there?
Thanks
