HELP: ppc mini's dvdr/cdrw drive no longer reads iso9660
Hello all
My original mac mini is protected by a belkin surge protector, however, I was in the middle of writing an email, when there was sudden loss of power for about five seconds. I was running slackintosh linux on the mini at the time... upon reboot, aiport no longer connected, and iso9660 would no longer mount. I confess I am a tinkerer, and the partition running slackintosh was formatted with the xfs filesystem--because I like xfsdump and xfscopy, and it is very fast--but the one problem with xfs is that it doesn't like sudden loss of power(I knew this, but was living dangerously, hoping to procure a UPS soon), and I attributed the new instability to the powerloss, and decided to start clean, by following the following procedure:
I inserted my original macmini dvd, and started up with the option key held down, and selected the hardware test--all tests passed, thought it doesn't test the optical drive.
I then rebooted into same dvd, and opened disk utility and reformatted the internal drive, with the option to write zeros to the selected--figured it couldn't hurt to rezero, even though it should have nothing to do with this problem.
Then I reinstalled os x 10.3 from same dvd, and immediately followed with 10.4 dvd's install.
So now I'm totally apple, on a totally clean drive, and still iso9660 cds will not mount. Sometimes it reports a blank cd was inserted, and othertimes it says they're unreadable.
To further complicate matters, I forgot to leave the heat on in my office when I went on vacation last winter, and I think my mini may have experienced temperatures below freezing--after that, the dvdr/cdrw drive (Model: MATSHITACD-RW CW-8124, Revision: DACD), stopped burning cds, but it has been reading dvds and all types of cds this past year without issues... still, drive had burning failure before said loss of power.
However, I feel it odd that it only lost iso9660. It still plays and reads dvds; it booted a panther startup cd; it plays audio cds. But iso9660s that open up on other computers, including my wife's g3powerbook, fail to mount on this mini.
Stumped to sadness 😟
