I have a 1TB External Hard Disk.
I accidentally selected the "Delete Volume" option in Disk Management,because of which the volume(External HDD) showed Unallocated and it was not showing up in "My COmputers" as well.Then i selected the "New Simple Volume" in the same option,thought it might help and completed the steps(but in one of the options i selected "Do not Format" in the end,because the drive stored some important files),which helped to show up the External HDD in "My computers",but now it was giving error "You need to format the disk ..." on connecting the hard disk to my LAPTOP.
 
I do not want to format my External HDD as there is almost 700GB of important Data in it and i do not have any other HDD of that space to which i can recover the  files to.
 
So, i again selected the option "Delete Volume" in Disk Management option of Computer Management.And till then i have been trying all possible methods including Trial versions of different softwares like "Partition Find and Mount" and others,but no result.
 
I tried running chkdsk but not of much help. Its giving below error.
"The type of the file system is NTFS.
The first NTFS boot sector is unreadable or corrupt.
Reading second NTFS boot sector instead.
Unable to determine volume version and state. CHKDSK aborted."
 
 
Kindly help me out.
 
 
Thanks in advance.
 
Regards

Download and install Partition Wizard. Run the Partition Recovery option. Do a Quick Scan and post a screen image of the result. If you do not see any partition listed then do a full scan which will take a long time on a 1 TB drive.

 

Edit: I am assuming you have not tried Partition Wizard yet.

I hope chkdsk did not write anything to that deleted volume.  As the earlier poster indicated, partition wizard may be your best bet.

I tried Partiton Wizard,but there was no result.

It was blank.

I  hope the files are  not deleted.


No,chkdsk Failed as it showed the error as i indicated in my first post.

Download Testdisk for Windows.Only download  the 32 bit version. Unzip to a folder on your desktop. Run the program. When selecting the drive it will be listed as Sdxx. For your external probably sdbx. At the Window that shows Advanced select it and then Boot. Does it detect a good Boot sector? Post a screenshot if possible.

Testdisk for 32bit will run on a 64bit computer and is the one which should be used. Some features are missing in the 64bit version. If you do a Quick Search does it find any partition? If a Quick Search does not find anything do a Deeper Search. If a Deeper Search does not find any partition then you will need to scan the drive with software such as Easeus Data Recovery.

 

PhotoRec is available in the Testdisk folder but files are recovered in real time to the folder you unzipped Testdisk to and all files have generic names.

I am trying the Photo Rec,and it is showin now "reading sector".

And it showed file will be stored in C drive which is only 80 Gb and my data on the bad drive is almost 700 Gb,will it still recover all my file.

It's safer if you can "tell" PhotoRec to save anything/everything it recovers onto a reliable available external media.

You cannot recover the files if the space on C is less than your external. You either need to pull the files off as they are recovered or get another external drive and unzip the Testdisk folder to the new external so files recovered will copy to the new external drive and not the C drive.

 

Edit: You can do a scan will Easeus which will let you recover 2GB for free. This will let you know if any files recovered are not corrupted and it would let you recover 2GB of your most important files.

I think  your files are gone. The only option may be to get a free quote from a data recovery service and they are not cheap. One of the better ones is DriveSavers.

 

One software that is expensive but people have had good luck with is Diskinternals Partition Recovery. You can download a demo to scan the drive and see if it finds anything. You would need to purchase a license to recover the files. 

 

I would at least give Easeus Data Recovery a try. It may find something. At least you would be able to recover 2GB.
