Strange FAT filesystem
My Garmin GPS device has a slot for an SD card. I'm using a 32 GB SD card which holds 22 GB data currently.
If I attach my device to a USB port it shows two devices, the internal memory and the SD card. I have no problems with the internal memory which holds only 2 GB of data.
I can mount both as a FAT32 system, but listing (ls) the large SD card based file system shows only rubbish (many question marks and dots).
Fdisk is telling me, it's a FAT32 partition.
BUT, when I start Windows7 under Virtualbox on the very same hardware, I can list the device just fine and CHKDSK doesn't find any errors. And Windows claims it's a FAT32 system.
I've even tried to execute mount.exfat-fuse but it cannot find an exfat file system.
Has anybody an idea what's going on?
Many thanks for a hint,
Helmut.
