Hello

I am working on a strange case with a 2TB WD disk, which is full of .mts files (client is a photographer).
For some strange reason he realized that one folder with the wedding of one of his clients is empty. (I do not have any other background history. I only get an "I don't know" response to my questions of how did this happen, or when did it happen).

I confirm this; for some reason this folder looks empty. I ran several s/w (R-Studio, UFS, File Scavenger etc) to no avail.

I thought of trying raw recovery on this. So I added on R-Studio this custom signature for .mts file:



I ran R-Studio with this signature. There must be something wrong with this; I stopped R-Studio on 30%, it gives me an enormous amount of files with total capacity of 78TB (!!) and each .mts file it found is ~2GB large (which is not normal).

Anyone has experienced something similar? Is there something obvious I'm missing? Thanks!!

einstein's suggestion was good, but it doesn't seem to apply to hdd's (only memory cards).

Some other suggestion?

Assuming you're working on a clone, and assuming the other files are of no interest, then delete all the visible MTS files and zero-fill their occupied space. Then search again for MTS signatures. In fact if you wipe every file of every type, then all you will have left will be previously deleted remnants. These remnants should be easier to search, and you won't be distracted by other file data.

Hello guys,

Have the same situation with a case here.. client format the partition for mistake.. using r-studio I was able to recover 70Gb from visible data including a lot of mts files but the client asked me for about 300Gb in mts files.. I added the file signature to r-tudio and like northwind the result is an enormous amount of files.. r-studio can´t determined the end of the file so is recovering files with 1/2 GB size and the original files should be between 8 Mb to 300 Mb.

Is possible somehow to recover the files with the original size?

I don't have R-Studio or a Sony MTS file, but I do have MTS files from my STB. I notice that these files consist of a stream of data chunks, each with a size 0xC0 bytes and an 0x47 byte at offset 0x04 in the header. The last chunk in the file appears to be no different to the others.

ISTM that you could check your recovered MTS files for consistency by reading each data chunk and looking for an 0x47 at offset 0x04 in its header. If your check fails, then that would suggest that you have come to the end of the file.

It shouldn't be too difficult to automate this procedure with some home grown software.
