SD card reading problems

Today I was shooting some pictures using some camera and a cheap 2GB SD card. Upon returning home, I copied the pictures from the SD card to the Mac, using an old 6-in-1 card reader. After about 980 MiB of images, OS X throws a read error. Using cp in terminal yields the same result. Trying to repair the card using the hard disk utility even resulted in the system hanging. No hard freeze, but I had to power cycle it, since I was too lazy to fire up another ssh-capable machine.
After some research, I read on Wikipedia that SD cards over 1 GiB are adressed differently. It seems that older devices, such as my reader may have problems using those cards. This means I have to go buy a new reader tomorrow, I guess! Or be restricted to using only 1 Gig of the SD cards I use... Which is not a good idea for camera producing 37 MiB RAW files.

Update: My suspicion was correct. A new 10 € card reader solved the problem. The 2 GiB are back, I can read all the photos from the card.
