not auto mounting removable drives - think I have an idea why

[Sprintrdriver]

Thanks. The dash cam is a type DOD 460 (I think - the label is worn out), so I'm going to put the card reader into a win7 computer, and I'm coming back after that.

[edit 1]
Can confirm that the file system is fat32. Running a windows error-check now, so in some minutes, I'll hopefully can confirm that there are file system errors.

[edit 2]
Disk check in windows completed - this is the summary:

Code:

Ok, I'm back on my LL computer now. After running a full disk check (and seek for hardware failure) in windows, the SD card still doesn't auto-mounts in LL (while the other SD card works properly regarding to auto mount).So maybe there is this space in the fat32 partition name "DOD LS460" tat cause trouble? Going back to the win7 computer and try to rename the volume and see if anything changes.

[edit 4]
Used the w7 computer to make the volum name blank, but when inserting SD card into card reader on LL computer, nothing happens - still.
I start wondering if it may be the SD card itself that Linux somehow doesn't support properly.

Storage card that works: ADATA 32GB micro HC I  |  micro HCI
Storage card that does NOT work: SanDisk, extreme plus, 32GB micro HC I, V30.

This puzzles me big time, guess if I'm confused by now. So what is next thing to try? Format the card from the w7 computer and see if LL behaves differently then.


[edit 5]
I have now formatted the SanDisk card using w7, regular formatting (fast format not used).

And the result in Linux Lite? Still the same!

So it seems like Linux just doesn't support some kind of SD cards. Can that be true?
