I'm suffering the same problem with one SD card, a card that works without problem in all my phones (Symbian and Android)

What seems more irritating is that I appear to be able to write and read to/from the card using DD without problem.. only filesystem actions seem to be affected..

the unix-engineer in me tells me it isn't specifically file system actions that are failing, as that in itself is gibberish..I expect it is certain actions that filesystem drivers are performing that cause the incredibly descriptive -110 error.

sequential read/writes don't appear to suffer, something else does..

my "faulty" card is type 2, but other type 2 cards work.. most are 16 gig, some eight though..

Just have one card with a problem..

(edit: all the cards are sandisk cards.. )
