OK.......here's the system info:
OS is Win2k (SP1) dualboot with WinME, fat32 is the file system on both.
Win2k as the bootloader
ASUS k7m mobo
256mb Micron RAM
AMD Athlon 750mhz
3 IBM Deskstar HD's 20GB 30GB and 45GB
ATI AGP All-In-Wonder 32mb video
SB Live sound card
Midtower with 300w Athlon power supply
The missing partition is 15GB and is the 3rd and last partition on the 30GB primary drive. Running Partition Magic 5.01 on 2 boot floppies.
Both OS's skip a drive letter in My Computer and Windows Explorer.
I either need to make the partition visible to Windows without a format or
extract the data with a recovery program that can access data on a hidden partition.
Any help is appreciated !
