Originally posted by pimpim I don't know when Sony introduced their db based storage, maybe it was different in their earlier bodies?
It's definitely present on my Hasselblad HV and A7 MkII. Whether the implementation is exactly the same, I don't know.
So far as I'm aware, the database is only relevant to the camera's reading, writing and indexing of files, and it's
additional to the image files themselves - not
in place of them. When you put the SD card into a PC card reader and the computer mounts the card as a storage device, it reads the image files directly like any other non-Sony-written card, and makes no use of the database. You don't need proprietary Sony software to read the files.
It would be easy to assume this database rebuild was responsible for the poster's loss of images - but let's not forget that folks lose images on SD cards without any database. If a card fails, it fails - regardless of camera brand...
