Ever since I got my Macbook Pro, it has not been able to read the black Memorex CD-Rs. Now this is just bugging me, because I have a whole 50-pack spindle of these things. It takes the CD-R in, makes the weird noises that it makes for 20 odd seconds and then pushes it back out. I've googled about this issue and it seems to happen to quite a few people. However, I tried the CD-Rs in my sister's combo drive on her macbook. This is the drive I have: HL-DT-ST DVDRW GSA-S10N Anyone else have this problem or know a fix for it? I read on some forums about a PRAM reset, but I have not idea what that is. Thanks in advance.
