Hi, i have an external CD-ROM drive (Yamaha CRW8424), and i'm able to mount it, but when copying files from a CD-ROM to the HDD, it randomly freezes the OS (7.5 - 7.6.1). Sometime, i can copy 50-100 MB from it, sometime it freezes earlier (at boot time for example). It only "works" With Apple CD-ROM extension 5.3.1 (with different versions, i can't mount it at all). Anyone have an idea why it freezes? The external drive have a terminator plugged in.
