Ohhh, I think you were supposed to change the 42 to 07. I believe there were three of them in that first sector. That could be why your file system was showing as raw instead of NTFS. I was so happy when my totally unbootable drive with lifeless alien looking partition just perfectly springed back to life. Well, the data was perfectly intact. Just had to follow step Three from this outstanding guide on repairing the bootloader using recovery dvd. Who would've thought simply converting my system drive to dynamic meant the worst MS Windows hell breaking loose...Made an account to Say thanks HxD got me halfway there.
After I changed the 47 to 07, the disk was recognized as raw. I could see all the data was still there from HxD though.
Thanks for this advice that I have followed using HxD that has partly solved the problem I have with trying to activate an invalid disk with 2 partitions insofar as when I followed the procedure only one of the partitions became active and the other partition remained invisible. Any suggestion about what I need to do to remedy this most welcome.
Here is the status of my current system:
1) HxD shows 2 physical drives "hard disk 1" and "hard disk 2"
My invalid HD "hard disk 2" has two partitions
2) I use HxD to change the 42 to 07, save, exit and reboot the HD
3) One of the 2 partitions opens normally, the other partition is invisible
4) Used HxD to change the 07 back to 42, save, exit and reboot .... back to where I started.
So not sure what to do?
Question: Is this problem caused by switching my OS from XP to Win7. I ask since if this is true and nobody can advise how to solve my problem I reckon I should be able to find another computer with XP, hook up and back up my "invalid" external HD that hopefully will run as normal on any computer with XP as it used to do before, then once back is done reformat my external harddrive with my Win7 system, right?
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.
