Any DR companies out there can handle recovery from an Olympus Digital Voice Recorder VN-7200. It is a non-USB version so makes it more complex. I think you need an eMMC adapter.

Hi, still use the same DR techniques as USB. More-n-likely have a flash chip in there.
want to take it apart and photograph it? or link to a teardown or something?

If you want to ship to AU I can look at it.

Yes, but it is little different. Usually Olympus voice recorder use own file system and sometimes it is a lot of manual work to recover data from this kind of device.

Yes, like DVR formats. But recovery will still involve desoldering NAND and reading. But yes it would be difficult if the file system info is not in public domain.

doing same here.

AFAICS, OLM.jpg is a standard MS FAT16 boot sector with a standard MS partition table at the end. That is, it is a boot sector and MBR in one.

http://averstak.tripod.com/fatdox/bootsec.htm

The partition table contains a single FAT partition (type 0x06) beginning at sector 0x8D and with a size of 0x3A3F73 sectors.

The BIOS parameter block at the beginning of the boot sector indicates that the sector size is 512 bytes, cluster size is 64 sectors, and that the volume begins at physical sector 0x8D and has a size of 0x3A3F73 sectors.

0x3a3f73 x 512 = 1 954 473 472

It would appear that the card has a capacity of 2GB.

The first 16 bytes of the next sector are consistent with a 16-bit FAT, namely "F8 FF FF FF FF FF FF FF FF FF FF FF 00 00 FF FF".

OLM1.jpg looks like a regular FAT root directory.

OLM2.jpg is the FOLDER_D directory.

ISTM that the clusters are assigned as follows:


I presume that the card was formatted on Jan 11, 2014 and that FOLDER_D contains no data. If so, then all the file system structures appear to be consistent with a FAT16 volume.

ISTM that one would simply mount the FAT16 volume beginning at sector 0x8D. As a precaution, I would write zeros to the partition table so as not to confuse your data recovery software.

In short, I don't see anything special about the file system. Does it look any more complicated when voice recordings have been saved to the card? Is that where the difficulties lie???

Are you saying you can recover the data? Please keep me informed.
