Windows 7: Partitions gone after Reboot

Windows 7 64 pro
Partitions gone after reboot

I have what looks like the same issue of Drive letter dissappears on reboot, my partition D.

I have 2 hard drives and have had for some time now, One Windows 7 64 Pro and the other Vista 64. The other night I installed media manager for my blackberry and upon reboot I lost my drive letter for D.

I also noticed the partition type had changed from NTFS to Compaq?
I cannot assign a letter to it, but I can delete and recreate it and it assigns itself driver letter D.. all is well until I reboot, dissappears again, I have tried everything that others in this post have tried.
One success is that when I boot to my second drive (Vista) I can recover the drive letter .. sticks after reboot to Vista but when I boot into Windows 7 .. gone!
The recovery is accomplished by changing the partition type back to NTFS

Apparently something happens at boot time. I would look in a slightly different corner.

1. Check whether there is any scheduled task at boot time that could do that (use the schtasks command in cmd)
2. I would disable ALL startup programs and see whether the same thing happens. If things work out well, you can troubleshoot those buggers one by one.

Logical partitions disappear upon reboot
Hi, Everytime I reboot my machine my logical partitions of the extended drive disappear. They re-appear only when I go to Computer management -> Disk Management and then do refresh drives. It is very frustrating as I have to do this for every reboot. Thanks, Pavan
