Dynamic disks no longer readable under XP
I just put on Vista Ultimate (Build 5744) on a separate partition on the same
disk as XP Pro (SP2 w/all updates). The Vista install went fine, all but one of my devices was found (USB floppy, no big deal), and everything seemed golden. I booted back to XP and everything was still fine there too. Then I come back to Vista and start looking around closer. I noticed in Disk Management that all of my mounted shares (i.e. partitions with mount points on a different drive; i.e C:\Media\Audio being a mount point for my Audio partition, C:\Media\Video being a mount point for my Video partition, and so on) had both a mount point *AND* a drive letter associated with them. Thus, C:\Media\Audio had both C:\Media\Audio and something like L:\ mapped to it. I wasn't sure why Vista felt the need to do that but checked and I seemed to be able to access files from either mount. Nonetheless, I don't like wasted drive letters and so set about removing the L:\ etc from all of my file-system mounted partitions. All but one such partitions were contained on a Dynamic Disk. The other such partition was a partition on the same drive as Vista, a Basic Disk. OK, so I do all of that and everything seems fine. I also go through and turn off indexing on all the drives which, like XP, is Vista's default to enable it. Also note that ALL of my physical drives other than the Vista/XP boot drive are Dynamic Disks. Next time I boot to *XP*, all of a sudden, XP no longer can access ANY of my other drives. XP Disk Management sees them but they are all marked as Offline. If I right-click and choose Reactive Disk, I get an error and am told to look in the System Event log. I do and I've pasted the event log at the end of this. Now I can see maybe Murphy's Law hit me with a drive failure, but 7 simultaneous drive failures?? I don't think so! If I boot back to Vista, all drives are readable still and I can access all files from them, and all mount points are honored. Since I have all my actual applications stored on one the Dynamic Drives, I figure, alright, I have enough space on one of the other drives to copy all the data from all partitions on that drive to the other drive. I'll just do that, reformat the Apps drive as a Basic drive, then bring everything back over. Nice theory but Vista's file copying is soooooooooooooooooo agonizingly slow. To copy a 30GB partition from one drive to another, with no other activity from me going on, took about 8 hours. Does ANYONE have any insight here?? I did open a Microsoft Beta Client report but no one from Microsoft has gotten back to me yet.

Dynamic disks no longer readable under XP
The solution is really simple (although not that optimal): in Vista/Windows 7 you assign the drive letter back to the volume, then it will automagically be available in XP and have that drive letter. This has happened to me on an XP/Windows 7 RC dual boot installation. And I've searched the internet for days to find a solution, without success. I had not realized that removing the drive letter had caused me the problems until I came by your post, so thank you and thank you again (as my spanned volume is 650Mb in size and it would require a couple of new disks and ages to back up). -- SeventhUser |
