I absolutely love the A-DATA 4GB Micro SDHC Class 6. It has worked flawlessly and swiftly until now. Recently, I loaded skins onto it but forgot to delete a second folder layer in one case, which left the skin folder an extra layer in. The other skins worked fine; when I selected this one, everything froze and I couldn't de-select it. This meant my card could play games so long as no system functions were used (including delete) but would freeze if I tried to access the OS menu. Unfortunately, at the same time the skin issue emerged, the card became unreadable on my MacBook Pro, which meant I couldn't fix the issue or load other games. I'd been using the USB reader that came with my AceKard2; I also tried the spare that came with my spare Acekard2. Neither worked any more. I went on playing games on my DS Lite in the interim, all of which worked perfectly. In a last-ditch attempt to get my computer to recognize the card, I decided to leave it and the adapter plugged into my MBP overnight, which actually worked. I've since deleted the extra skin folder and uploaded more games, as well as the last official update from AceKard (not Brian's version -- until after I've made certain things are completely stable, I'm not toying with more variables). So far, everything has worked perfectly, but I have a bad feeling about the AceKard USB adapters. Question 1: Can anyone recommend a better alternative to the AceKard USB adapter? Question 2: Has anyone else had intermittent access to the A-DATA Micro 4GB SDHC from their CPU, and did this arise during similar problems with the AceKard2?
