TestDisk can't find partitions/Log not opening

[JamesMaguire]

I have been trying to recover data off my external hard drive, but TestDisk cannot find a partition (with both scans) and PhotoRec is not working as well. Because the drive is 1TB, the log file is over 1.65 GB and freezes any document reader. I've been trying anything for about a week now, so any help would be greatly appreciated.

Did you get error message while scanning with testdisk or photorec ?

[JamesMaguire]

No errors, just no found partitions (damaged or otherwise).

I guess your Testdisk log file is full of read errors!
Try to open up your big log file with a hex editor that will only read parts of your file and try to screenshot or write down the asumably repeating messages.
Another way is use any programming language and read the first 10k bytes of the logfile and write them into a new shortened logfile that can be easily opened with a standard editor.

That was able to read it. Thanks.

Unfortunately, this is a case for a professional data recovery company.

[JamesMaguire]

I was afraid of that.
Is there any pertinent information I can give them?

A general error description perhaps?
Information about the partition layout and file systems used could be helpful.
I guess they will ask you when they need information.

Oh, I meant if anything from the log revealed any specific reason for the problem.
Regardless, thank you both for the help.
