Hi Albarts,

ImDisk? I don't know that one. Did a search and found some people talking about it.

I have not read enough to make my mind up, but it looks like it does create RAM drives.
My question is: does it work? Most motherboards have a limit of 8, 16 or 32 gigs of memory.
Average users might have 8 gigs installed, tops.
But your problem card is 64 gigs. How does that work?
I need to read more.

If you are using WinHex, it should not be too difficult for you to get the signature
for the .MXF files. Follow the instructions to feed your signature to PhotoRec.

You might want to modify the name indicating the type of file slightly (something like
.MXV or .M3V), then deselect all files, mark just the ones with your signature and
search the whole of the card clone or image. Any files you manage to pull this way,
can be easily be rename as .MXF later.

With a full clone of the original card, you probably would make
your job easier. If you have access to a different card adapter or reader, it would also
be worth trying. Not all readers or adapters are fully compatible with all cards.
A speck of dust or a smudge in the metal contacts from someone's fingers could throw you out.
Checking carefully slows you down but it wont do any harm.

Found a link to this tool: ... ir_Utility

Instructions on how to use it: ... a16bcefbf5

You will need a copy of an undamaged .MXF video file. A video file from before the problem started.
The obstacle still remains on how to get hold of a complete .MXF file, albeit damaged, from the card.

In theory, it would be possible to create a slightly bigger FAT32 partition in one of your HDDs.
That can be easily achieved from the Partition Wizard CD.
Then, using a tool like Win32 Disk Imager, turn one of those images you created earlier into a disk. ... n-windows/

If it does work, you could use TestDisk or PhotoRec in the FAT32 partition.

Or you could run PC Inspector File Recovery 4.X, under Windows:

Here is a link related to SD Cards:

In the Downloads section you will find a card formatter for Windows and also for Mac.

For more tools and ideas,

Hope this helps.

Best of luck
