Hi, new to these forums & have not tinkered with Macs since OSX. Things were going OK with my G4 until a few months ago. I added an SATA card & HD on the G4. Things went fine for a while, then I could not boot from the HD. I booted from the CD & went to use Disk Utilies. HD was named some long string of garbley-gook & I could not run any utilities. All were grayed out. After trying to reboot s few times disk disappeared! Bought a new SATA card, no difference. Bought a new SATA HD, no difference. Returned both. Now stuck trying to figure this out. New disk utility program? Anyone with any advice. Thanks.
