Quick Mac question

[jollyperv]

I don't know macs very well, I need to get some files off of my gf's powerbook g4, but the fucker won't read cd-r's or cd-rw's....am I missing something here? I restarted it, once it boots I get the error " You have inserted a disk containing no volumes that mac-osx can read " ... Worked fine last week.

Reboot gain but don't leave the cd inside, take it out and put back again in the drive when it boots.. hope this helps.

make sure the cd-rom is capable of reading cd-r or cd-rw cuz some are not and if its somthing only windows can read there might be a problem.
