How to explain this? I tried to transfer pictures this evening from the SD card using an external card reader and there appeared to be card errors so I switched to the internal card reader in the laptop only to see the same errors. In both cases the file count was 183. I put the card back in the camera without making any changes on the computer and connected the camera via the USB cable. File count now 238 with no apparent corruption. I was able to transfer all files without issue and all look ok.
Jumping back to the fake corruption: the first two files as well as a group of files at the end of the list had filed names that contained only symbols (|<{%[€^£ as an example but they were symbols from the extended ascii character set). The first file had a listed file size of 2.2 gig with the second file being 1.1 gig.
This is all on a fairly new sandisk card which appeared to work fine yesterday in terms of using a laptop's internal card reader to transfer files. (Not the same laptop that I used today) Once the pictures were moved I did an in camera low level format. See how that works. My other thought was to use a windows computer to do a low level format but which fat file system do I use?
Anyone see this kind of thing before?
Thanks for any input.
