Recover file from recorder after power off

[ACCakut]

Hi,


we use a Tascam rack-mounted recorder (SS-R1) to save audio from XLR to CF card in our church. Unfortunately somebody turned of the whole installation while still recording. Due to that the file is not properly saved and "lost" as seen by regular file explorers.

Can you give me some hints how to recover the recording? Testdisk and Photorec found the file but size was 0 bytes. I didn't try other tools since some live CDs seem to have problems with my card readers or the CF card.

If I could get the "position" of the file, I could find it in a dd-image etc. and extract the audio stream by hand.

File system should be FAT(32), CF card is about 4GB.

Thanks in advance,

Philipp

If you run CHKDSK in readonly mode, does it find any orphaned clusters?

If you run DMDE against your drive, does the missing file turn up in a FAT32 search?

I would use DMDE to image the whole card(not partition) and work off that. The card right now is the ONLY copy!
it is also possible it wasn't actually saved

Thanks so far, I'll try this.

I was quite sure, there has to be "any" data since the recorder can't buffer all the recording by itself neither it can write the whole data within a second when pressing stop...

Ok guys, I solved the problem. Windows and DMDE showed the missing file without any recovery, but just showing 0 bytes (seems "fine" since the recorder should have created a file but didn't finish). DMDE didn't help my so far (except making an image) but a simple CHKDSK /f brougth the the lost data. Thanks!
