I have never used Disk Drake. But if you want to completely get rid of the Linux Partition and get a FAT partition instead, then you can also do it from Windoze, using the "Computer Management" tool from the Control Panel. Alternatively, you can use some other software for windows (Partition Magic, for instance. But I'm not really keen on "buying" software.)
The other thing that can be done is that you pop in a Linux installation CD, and see if you can delete the paritition you dont want. But deleting the partition will oly be an incomplete step, you will have to format it into FAT, which I recommend you do in Windoze.
There is yet another mothod. Pop in the Windoze XP installation CD. Keep going on till the part you choose a partition. Then delete the Secondary partition and format into FAT. Then quit the installation, otherwise you will have two copies of Windoze on your disk :P
WARNING: the method I have described will delete ALL data from the Linux partition. I hope u know what u are doing
I hope it helps.
