Hi there - I am new to this and not very up on the technical side, although I have done a considerable amount of reading and learning over the past few days!
I keep all my photos and videos on a 2TB internal disk which suddenly became unreadable by Windows (8).
Using TestDisk for the first time, I found that the boot sector was bad and I successfully used the back up boot data to make the primary partition readable. There is only one partition on the drive, occupying the whole (2TB) disk. I then copied all the (191 932) data files to a portable HDD with no errors.
Even though TestDisk is able to read all the information on the Primary partition, Windows cannot access this partition and sees the disk as a RAW volume which needs formatting. I sense there must be some way of modifying the MBR or MFT (not quite sure what the difference is!) so that Windows can then see all the data which is still on the partition and I can continue using the disk without having to format it. Chkdsk gets as far as 53% and then gives an error saying there is not enough room on the disk to write to it (or something like that!).
The initial TestDisk Log is shown below, which includes me restoring the boot data from the backup. Any help on getting the disk back to good health would be much appreciated!:

Re: All data recovered with TestDisk but NTFS HDD unreadable
do not format or write if you havent baced up all your data, intended...
see if you can assign the drive a letter also, try on another pc witx xp on it, or linux.

Re: All data recovered with TestDisk but NTFS HDD unreadable
I am currently building a new computer so will try on that one. Not sure what you mean by intended...
Re: All data recovered with TestDisk but NTFS HDD unreadable
Boot sector looks ok now.
Might be possible that your file system is faulty.
If you've already recovered all your data, you can have a try to repair your file system running chkdsk driveletter: /r
within your command prompt.
You'll need administrator privileges.
If it doesn't work for you, you can reformat your disk and copy all your data back.

Re: All data recovered with TestDisk but NTFS HDD unreadable
Many thanks Fiona. Chkdsk did not work on the original computer but I will have a go on the new one once I have finished building it as it has a much more up-to-date motherboard and I sense that the 2TB disk was an issue for the old one!
