I've been using Windows 7 for a while now but all the sudden I'm having an issue with one of my Hard Drives. I have a 320gig SATA as my primary system drive, a 500gig SATA data drive (this one is set to 'dynamic') and then an 120gig ATA drive (That I currently have no data on yet.)
For a couple of months now all was fine. My primary drive was assigned the letter C: (durr,) the 500gig was set to G: and the ATA was set to D:.
I have all of my music and stuff on my big drive, the 'dynamic' one. So I turn on my computer and click a shortcut to my music on my desktop and I get a message saying the link has no target, so I open My Computer and lo and behold, G: is gone. I go to Control Panel -> Administrative Tools -> Computer Management -> Disk Management and I see:
"Disk 0, (D) basic, healthy, primary partition"
"Disk 1, (C) basic, healthy, primary partition"
"Disk 2, (supposed to be G), dynamic, invalid"
When I right-click on it, I get the option to 'convert to basic disk' (lose all data on it,) or 'reactivate disk.' Selecting the latter option gives me the error "This operation is not allowed on the invalid disk pack."
Properties reports the device is working properly, my bios sees the drive as well...???
There is a tiny white bubble with a red down-facing arrow over the drive icon there too that's looking kind of bad...
I downloaded HxD, a disk hex editor and opened the disk in it. In sector 0, location 1C2, the value read "42." This means dynamic drive, so I changed the value to "07" and saved the changes and rebooted.
Upon reboot I went back to Control Panel -> Administrative Tools -> Computer Management -> Disk Management and there it was, no longer 'invalid' but instead said 'healthy, NTFS, basic.' Glee!
I had to reboot again though for some reason because I was unable to change the drive's name (not path, just name) and also the drive was not appearing on the left in my library's window. After a 2nd reboot though it was back to the way it was and the disk is no longer dynamic.
I thought this was odd to begin with though because I used Windows7 to make that drive dynamic in the first place, so I have no idea as to why it would suddenly lose support for dynamic disks
Oh well, I'm happy.
