Undoing Remove Partition

[CHANGE USERNAME TO westes]

I accidentally removed a partition in Computer Manager and would like to get
it back. Is there any easy way to do this?

As a worst case, could I use a tool like DSKPROBE to change values in the
partition table manually? Would I be able to just change the value for
the volume type (e.g., FAT, NTFS, Dynamic), or would I also need to tweak
the values for start and stop cylinder, etc? In other words, does
Computer Manager destructively reset all of those values, or does Computer
Manager simply wipe clear the partition type attribute in the partition
table?

Hello,
The partition table is zeroed out. You do not necessarily have to fill in all the information such as beginning and ending cylinders. However, you should at
least indicate the partition type, the relative sector, and the total sectors.
You can find the relative sector, where the partition begins, by searching for NTFS with a 3 hex offset and ASCII for NTFS partitions. When you find the boot
sector for the partition in question, use the total sectors indicated in the boot sector plus 1 for the total sectors in the partition table.
If the partition is the first partition on the drive it is generally located on sector 32 or sector 63.
If it is the second partition or later, you can traverse to be boot sector of the first partition, choose volume end, then read the next sector. Now this is well and
good if they are primary partitions. If it is an extended partition, it is a little different and I will stop here since it is a much more lengthy explaination.

Sorry for the bother, but mechanically what programs do I use and what steps
do I take to do what you are suggesting here?

The drive in question had a Compaq partition in the first partition
position, followed by an NTFS in the second partition, marked as Dynamic.
