Hello Andrew, thanks for your reply. Here is the output from dumpexfat:
Volume serial number 0x61613331
FS version 1.0
Sector size 512
Cluster size 131072
Sectors count 124702720
Clusters count 486992
First sector 32768
FAT first sector 16384
FAT sectors count 16384
First cluster sector 32768
Root directory cluster 4
Volume state 0x0002
FATs count 1
Drive number 0x80
Allocated space 100%
The card content was the usual Panasonic directory structure with JPEG
files in subdirectories of DCIM; when a subdirectory reaches 1000 files
a new one is created. I restored my pictures with testdisk, so I can
tell there were 7069 pictures in 8 directories – but that includes those
that I had deleted and which were partly also restored by testdisk.
Here is the directory structure; I think I had deleted 124_PANA,
125_PANA, and 126_PANA but am not exactly sure:
- AD_LUMIX
- GPSDATA.DAT
- GPSDATA20171027.DAT
- DCIM
- 124_PANA (642 pictures restored)
- 125_PANA (993 pictures restored)
- 126_PANA (998 pictures restored)
- 127_PANA (993 pictures)
- 128_PANA (997 pictures)
- 129_PANA (996 pictures)
- 130_PANA (998 pictures)
- 131_PANA (452 pictures)
- MISC (empty, not restored)
- PRIVATE (Panasonic proprietary data)
I suppose that the deleted 124_PANA also had contained almost 1000
pictures but that many could not be restored because their space had
been used to store new pictures.
Anything else I can do?
