How to recover corrupt PARTITIONED drive


Hi guys,

I used windows7 ultimate but then it crashed. Formatted the system drive and went back using Xp again, however, my PARTITIONED drive is now unaccessible and somewhat it is corrupted. I never touched the drive during the reformatting process but somewhat it says now it is corrupted or I need to format it again to access it. There are lots of file that really need to get on that driver. Please help on how to or in any way I can recover those files as much as possible... please....

If I understand you correctly, you have either a retail, or an OEM version of Windows XP and you used that to reformat the drive and reinstall XP after Windows 7 failed. Although reformatting effectively removes the data envelop, the data itself remains in place and can sometimes be recovered with specialised software. However, such programs are not free and are not guaranteed to work. Have a look at this one: How do I recover the files from formatted hard drives?

Thank you for the information. I am checking on it now. Any other possible solution, please don't hesitate to share the knowledge.

Thank you...

Please...post the exact error message which was onscreen...which led you to believe that a partition/file system/drive was/is corrupt.

There are any number of free utilities which can be used to attempt to recover data files, a few that members report as having worked for them:

Partition Find and Mount free partition recovery software - http://findandmount.com/

Recuva - Undelete, Unerase, File and Disk Recovery - Free Download - http://www.piriform.com/recuva

Recovery Software, Partition Table Doctor - http://www.ptdd.com/

Recovery Software, Recover My Files - http://www.recovermyfiles.com/

I don't mean any disrespect but I have found that the easeus product is misleading ESPECIALLY with regard to its claims about recovering data from formatted partitions and disks. You will do just as good with free products like Recuva or PhotoRec.
http://www.piriform.com/recuva
http://www.cgsecurity.org/wiki/TestDisk_Download (PhotoRec is included in the TestDisk download)

Depending on the filesystem you probably will not be able to retrieve the filenames or directory structure and will have to look at each file it recovers and rename it. This is true with easeus too even though they seem to go out of their way to keep from telling you that until you have their products all over your system.

For example, in NTFS systems (when quick format is used and the disk hasn't been overwritten with 0's) I do a lot of work to attempt to manually recover and repair the old MFT to a point where I can read the directory structure, filenames and data runs(where the files are on the disk) from it and then I can recover most of it. Sometimes I can't and I just use the tools I listed above and rename everything I can figure out :)

James,

I've used Recuva myself and found it to be a total waste of time. But your experience may be different. I don't know about the other one you mentioned.

As regards the product I linked to, it appears to be a little more informative than any of the others I've come across and that was partly the object of the exercise. There's also a free version of the application available for download so that the user can test the product without having to put money on the table first.

I don't want to hijack this thread any further and would be happy to discuss the features of available recovery products in another thread. In a forum like this I try very hard to only recommend software and techniques that I can use myself and give specific and detailed instructions on. Often the users looking for help are not experienced with computer repair jargon and technology.

To bring this thread back on course :) Corneto_20, please answer Louis' question so we can help you find a solution...

Please...post the exact error message which was onscreen...which led you to believe that a partition/file system/drive was/is corrupt.

Thank you for the reply guys. I really appreciate it. The one that was formatted is actually only the system drive c. However, the partitioned drive was never formatted. But after all the reformatting of the system drive c and installing the new OS, I am not able to access the partitioned drive E. It seems that the issue causing the computer to crashed started in my partitioned drive. When I clicked on it, it only gives me a message that the drive is not accessible and needs to be formatted. When I check it under disk management the drive says there it is healthy. There are at least a thousand files saved in that drive. That is why I am really trying my best to get it back. With those links that you have provided me guys, I am looking into it now. I will give you the feedback any messages that I will get. Thank you guys.. God Bless...

<<However, the partitioned drive was never formatted,>>

Impossible...in order for a partition to exist...in order for Windows to use any hard drive or portion thereof...the drive must be formatted and evidence at least one partition.

Unformatted space on a hard drive is just unrecognized/unuseable space in Windows...the only way to even see such is to go to Disk Management within Windows.

Louis

Typically...when Windows gives a message that a partition needs to be formatted in order to be used/accessed...that's an indication that a previously formatted partition has developed troubles of some type so that Windows can no longer read/recognize it.

CHKDSK error message - The type of the filesystem is RAW - http://www.z-a-recovery.com/art-raw-filesystem.htm

The problem with such partitions...may originate with failing hard drives or damaged partition/file system files. Recovery software is the best option (IMO) of accessing any data files which may lie on such partitions and success is not guaranteed.

Since a partition is not showing that should be, you can try a partition recovery. In order to do it safely without losing your data, you'll have to follow my instructions carefully. First we can look to see if we can easily fix it.
That is we look but do not change anything. :)

Get a copy of TestDisk from
http://www.cgsecurity.org/wiki/TestDisk_Download

When you extract the downloaded file one of the programs is
testdisk_win.exe
Double click it to run it and it will open a black window.

Make these selections

CREATE (to create a new log)
use up/down arrows to select the drive with the missing partition
select PROCEED and press enter
INTEL
Analyse
Quick Search
Answer Yes to the question about it being created with Vista or Win7 (even if it was not)
Let us know what partitions it lists and if they are green or white.

Press the letter q 4 times to exit the program.

This way you look but do not make any changes and this will tell us if we can quickly recover it.

James
