I sit here now with a failing 120 GB Hard Drive in my Powerbook becuase of the Card reader that came with my R4. There are a few different card readers that R4 is pacakaged with. The one I'm talking about is the transparent Blue one, somewhat of a trapazoid shape. The thing is a piece of crap....very cheap feeling. Anyway, I was doing some ROM transfers and the thing disconnected by itself, TWO times. Making me have to 'force-shut down' once and restart another time. Since then, my hard drive started making noises....next thing I know, it's status is now "failing". The damage has affected TONS of my files... currupting random pictures, movies, roms, tons of things...THings that were not even involved in transferring. I cannot back up these files because they're currupted and can't be copied. Yes, I have a Mac, and I know a lot of you don't, but I'm just warning you. I highly advise you to get a durable USB card reader if you think yours feels cheap. Before I found out my computer was fried, I actually exchanged the reader where I bought my R4. The guy gave me a MUCH better black one that is VERY durable. If only I had gotten this one first. RIP Powerbook. And no, I'm not under warranty.
