Disk particition is missing

By beanxyz ·
I meet a very strange problem. One of the laptop got two particitions, and for some reason the disk has corrupt files and can't boot. I connect the disk to another computer and let windows xp to automatically recovery those corrupted files when started.

Then the problem happened: the disk is about 140G and each particion is 70G. From device manager, I can see a "D" drive of 140G, but from windows explorer, the D drive is only 70g! I don't know how come device manger can recognize the whole disk but only displays one particion. I need to restore some important files from the missing partition.

Any suggestions will be appreciated.

If the files are really Important you should pack up the drive and send to a Data Recovery Specialist as the more you mess with the drive the more damage you can do and the more it will cost you to recover the Data along with the possibility that you may render some or all files impossible to recover.

If the data would just be nice to get back and you can live without if necessary you can try one of these which is a short list of the better programs available

While the last 2 are from the same company they are very different products. Win Hex should only be considered for use by someone who knows Hex Inside Out while Davory is a great cheap General Purpose Application.

Personally I prefer the On Track Option but it's anything but cheap. However because I use this type of software a lot it's paid for itself many times over by now, for a cheaper option Spin Rite from Gibson Research or Stella have both very good reputations by other TR members.

Also try the HDD makers Disc Testing Utility to just confirm that the HDD itself isn't failing.

Yeah, the partition information is bad.

As neither reading is correct. Best to stop booting this drive until it is fixed.

First, download the hard drive vendor's testing utility and run the tests.

If the drive is failing, you are looking at a data recovery route.

If the drive is OK, run a
chkdsk /r
on it while it is slaved to the other system.

You may then need to fix the partition table with a partition editor. Download the UBCD and try scanning with various partition tools to see if one finds the errors and can correct them. This disk also has HDD testing utilities as well, and may have the one for your HDD vendor. http://www.ultimatebootcd.com/

edit:
You may need to run chkdsk /r again after.

If this isn't your cup of tea, you may simply wish to go with data recovery, and I see that OH Smeg has already posted his list while I was typing this.

thanks guys I will give a try

I've already test the disk to make sure it's fine. There are too many recovery tools, and I just randomly pick up one trial version to see if it can scan the missing partition, and it takes a long time to scan.
