Solved Drive C partition unallocated

[zirch]

Is it a seagate disk? Use seatools bootable CD to diagnose the physical disk.
Western digital has a diagnostics tool as well. Post results

It's Western Digital. I'll look for the diagnostic tool. Btw, thanks for spending the time to help me. Really appreciate it.

PQSERVICE partition isn't working as well as far as I know. You get a bsod when trying to boot from it. Correct?
You have a win7 ultimate install dvd? And a valid product key? I think you have lost C. If you are clean reinstalling.... delete PQSERVICE partition first with partition wizard. What's on the 3GB partition? Maybe you can delete that as well. Extent DATA afterwards.

This is a case where some system specs, at least an Acer model number, would be very helpful.

In Post #4 I see that you have 2 Disks. This leads me to wonder if your particular laptop has a mini PCIe SSD installed.

This would be important because if it does then the mpSSD and the C: (OS) drive work together like a RAID array. And that could make a lot of difference in how you proceed.

Disk 2 is just 8GB and FAT32. Most likely a usb stick.

I don't know how to create an usb bootable MiniTool Power Data Recovery stick

I think I'll do a clean reinstall eventually. But before that, I am hoping to be able to recover my files from C.

 

[TVeblen]

Me neither.

You are probably right though. I thought that might explain why the recovery methods were not working. But it is probably just a USB stick.

My system is a laptop, Acer Aspire 4920G. Disk 2 is actually the USB drive from which I booted MiniTool Partition Wizard.

Testdisk is the tool (maybe the best) for finding/recovering partitions. Most of them can do a quick and full scan (called deep scan in test disk). Some tools can even find files in unallocated space!! You can search yourself on google or make a new thread.

• most likely testdisk didn't find it and updated the partion table, so i't's unallocated now. Or it was already... I don't know.
• Who did delete/corrupt the NTFS structures on partition.... I don't know. Testdisk and Partition Wizard didn't do it.

Try some hardware disk diagnostics tools (like seatools for seagate disks). To prove disk is still healthy

My laptop uses a Western Digital internal drive. There is a diagnostics tool called WD Data Lifeguard Diagnostic. However, it needs to be run from Windows or from a DOS bootable diskette. I have no diskette or diskette drives. So it looks like I may have to take out the hard drive and attach it to another computer via an adapter.

You don't have a CD/DVD drive?

My CD/DVD drive is spoilt already. And I don't have a CD or DVD now. Though I can get one and use another computer to burn it. Haha. I didn't think about it. Thanks.

You may run the WD Data Lifeguard Diagnostic for DOS from a bootable pendrive. You can find it under For Windows and Mac

Did you read the instructions?

QUICK TEST - This option tests your drive quickly for any major physical problems. (Please note: Although this option is safe and does not alter the data on your hard drive, Western Digital recommends that you have a current backup of your data).
EXTENDED TEST - This option checks your drive thoroughly and it can repair any correctable errors. (Please note: Although this option is safe and does not alter the data on your hard drive, some data loss may occur, depending on the errors found and the errors corrected. Western Digital recommends that you have a current backup of your data).
WRITE ZEROS TO DRIVE - The Write Zeros option, wipes all data off your drive. This option used when your data is no longer usable or recoverable. If you no longer need any data from your drive and would like to start over, run this option to set your drive to an as new condition. NOTE: Please make sure that you have selected the correct drive to perform this function on as once ran, no data will be recoverable.

Do quick test first. If no errors... do EXTENDED TEST
DON'T WRITE ZEROS TO DRIVE!!

Ok. I did a quick test with WD Data Lifeguard Diagnostics. The test was completed without errors. So where do I go from now? Does it mean my data is still somewhere in there?

Yes. I read the instructions. Thanks for reminding though. I'm now running the extended test. Estimated time remaining: 1 hour 15 mins.

If you want to run TestDisk and attempt data recovery, you may create a Bootable DOS pendrive in a similar manner.

Download TestDisk DOS/Win9x version http://www.cgsecurity.org/wiki/TestDisk_Download and unzip to a folder.

After you create your Bootable DOS pendrive with Rufus, move all the files in the folder to the pendrive. Then you can run testdisk.exe or photorec.exe from the booted pendrive.

Read all the documentation in the TestDisk website.

Thanks. As I'm now running the WD diagnostic test, which will only complete in another hour, I guess I can't use TestDisk yet. In the mean time, I'll read up on it.

You can do the extended test as well. But I think the disk is totally fine.
Very important stuff on C? No backups?

You can recover files ... even from unallocated space

Yup. Running the extended test now. Still 1 more hour to go before it completes. I usually perform a manual backup every few months. But for the past few months, I have some files which I haven't managed to backup. So if possible, I'd like to recover those files. It's quite important for me.

After the extended test is done, which I'll expect to be ok, I'll try to run file recovery tools, maybe TestDisk.
