Onto my Windows XP system I installed the Roxio software – Easy CD & DVD Creator Basic 6 and Drag-to-Disc (formerly known as DirectCD) – that came with a new Plextor PX-708A .
One result is that it messed up all my drive letters. My setup had been:
Hard Disk 0: C: primary partition - NTFS, Windows system partiton
D: primary partition - NTFS, for programs
E: primary partition - NTFS, for data
R: logical partition - NTFS
K: logical partition - NTFS
O: logical partition - NTFS
Hard Disk 1: Linux boot partition - primary partition - ex3fs
Linux swap partition - primary partition
W: primary partition - NTFS
Linux / partition - logical partition - ext3fs
Linux /var partition - logical partition - ext3fs
Linux /home partition - logical partition - ext3fs
I was able to use the Disk Management part of the Windows XP Computer Management console to change back the drive letters for C:, D:, E:, K:, and W:.
But I could not use the same thing to change back the letters for R: and O: because Windows has stolen those letters: Windows now sees the 5 Linux partitions and in Explorer shows each as a Local Disk and assigns a drive letter; among the drive letters are R: and O:.
According to Plextor tech support, it was indeed installing Drag-to-Disc that caused the problem. They said it’s just what Windows does when you install such a file-system extension.
So the question is how to fix this. Evidently the Windows Drive Management route won’t work. I hesitate to edit the registry for such a low-level matter, but is that the best next thing to do?
Note: Using PowerQuest Partition Manager is not an option: It doesn’t get the location of Linux partitions right – or at least not in a place that agrees with where RedHat Linux expect them to start. (I’ve experienced this on several different dual-boot systems.)
I haven’t actually installed Linux on the partitions in question, so I’m willing to delete them and re-create them. But if I do that and then use Windows Drive Management to change the two wrong Windows partition letters will I just wind up where I already am once I recreate those partitions?
Or should I try to edit the Registry? The keys are, I believe, in:
Sorry if this is somewhat off-topic for the forum. But since the problem resulted from installing CD software, I thought somebody here might have experience with the same sort of thing.
