My system is a home built PC with multiple HDDs. I have 4 GB of memory. Current OS is XP SP2.
Problem originated when I went to rebuild system. I disconnected extra HDDs after writing down drive letters and sizes.
Needed a legacy system with XP and no service packs due to problems with video editing software and inability to locate old patches that were necessary with SP1 and up. All the links are dead.
Long story short, I moved data to additional HDD and disconnected it. Currently connected HDD is 1 TB with 3 partitions: C, D, and H. I reformatted C, installed XP Pro SP2 (cannot find my XP pro disk without service packs so I'm moving forward with a newer version of video editing software). XP Pro computer management showed C, D, and H partitions. C was boot partition, for some strange reason D was listed as "system partition". Not sure why, was never this way before as far as I can remember.
I know it was a stupid thing to do, but I decided to install partition magic and see if I could change the system partition from D to C. I couldn't understand why system partition was on D when OS was installed on C. I did not make recovery discs. Also, data on D (approximately 40+ out of 48 GB partition was not backed up. I didn't think there was much risk since I've used Partition Magic in past with no problems and I was not resizing or moving data. Well system froze. I rebooted and now my D drive is a PQrP drive.
Didn't know where to start since I've seen several ideas after googling problem. Some say use PTEDIT.32, others suggest partinfo tool first, some say recover data first. I can move my data from H, and I don't care what happens to C. I'd like to recover D since I don't remember what is stored on it. Can I recover data without fixing partition? If so how? My memory of DOS commands is rusty. Finally, if you think PTEDIT is the way to go, do I just boot from PM installation disc - what commands do I need if it is a DOS environment?
Solved! Go to Solution.

I think we should clarify a few things.
You must have tried to use the "Merge" function to combine the C and D partitions?
If not, how did you try to "Change system partition" from D to C?
Your system boots properly at this time into XP and XP really is inslalled on the C drive?
What used to be D is now a pqrp partition that you can't access and it contains data that is not backed up?
What used to be on that drive, were those partitions originally made with Vista or Windows 7 or did you create those partitions during the installation of XP.

When you installed WinXP recently (after the reformat) you had D: drive as the Active partition so your booting files were installed into the D: drive and the Windows files were installed into the C: drive. Not an uncommon mistake.
Use ptedit32.exe and tell us the "Type" of each partition.

Unfortunately it has been about a month since I last played with it.
This hard drive had 3 partitions, C, D, and H. I reloaded XP after reformatting the C partition using the XP Pro installation disc (and after backing up desired data from C).
Windows would not let me change the C partition to the system partition. It says it is the boot partition. I looked in explorer and the OS is on C.
I installed partition magic. I didn't merge the two drives C and D but was trying to change D from primary active to logical or something along those lines, but I'm sure I wasn't trying to merge them. Partition Magic appeared to get stuck so I rebooted. My thinking at that time was that perhaps windows would let me change the "system drive" to C if D wasn't primary active or something like that.
Yes, D is now a PQrP partition and it has old data and I think pictures I may need for my videos when I get back to doing them. I didn't back up D and I haven't tried to access it with anything except partition magic (I haven't tried PTEDIT32). PM identifies the drive as PQrP.
The computer boots fine to the C drive, although I haven't finished loading the video drivers for the add on card. Prior to this bad idea of mine to change something that probably didn't need changing, at least right now, all partitioning had been done through the computer management console in windows XP.
Thanks for the assistance. Hoping someone can point me in the right direction before I make another bad decision.

Thanks Brian K - I'm on lunch break at work right now, will run PTEDIT32.exe when I get home in a few hours.
Do I boot to partition magic install CD and run it there? or can I run it from within windows environment? DOS is not my strong point.

What I'm getting at is, I don't know if I would trust ptedit to change the partition type if the partitions are not cylinder aligned.
Since PM does not support sector aligned partitions, it may want to try to "fix" the partitions making it worse.
Thats why I asked what was used to create the partitions in the first place.
When you formatted the C drive to install XP it didn't change the actual partition, it just formatted what was in that existing partition.
Did that drive ever have Vista or windows 7 installed on it, or where the partitions possibly created with one of those operating systems?

You can run ptedit32.exe from Windows or ptedit.exe from the PM boot disk.
Can you run it from Windows and post a screenshot of Partition Table Editor?
Or post a link to Photobucket etc.

I had forgotten about ptedit32 and running it in windows.
I'm sure that would be fine.
But if you end up having to use the floppy disk set or the product CD, do not let partition magic "fix" any errors it may find.

The drive never had Vista or Windows 7. And you are correct, I just reformatted the existing C partition and installed XP Pro with SP2.
I don't want to make it worse if I have a chance of making sure I really don't still need any of the data. There could be a few hundred scanned and edited photos in there from two montages I did for family weddings. I may need them for the wedding videos when I get time to do them and get software loaded that is 100% compatible with my hardware. But that is another story.
Since this is my 1 TB drive, I know that I've only had XP Pro on it. Thanks again for the help.

Thanks Brian and Dave!
I'll run it when I get home, grab a screen capture and throw it into Paint.
Even if the data does not prove to be crucial, this is a valuable learning experience in trying to recover it. I'm glad there are guys like you both out there to help us out with our stupid mistakes.
