10.2 Murdered my SCSI!! |

Goodie Goodie!! I figured I had the $200 to spend, so I went out and purchased Jaguar. I couldn't stand having a out-of-date OS, and since everyone is now on to making "Jaguar" Applications, I figured 10.1 would be gone soon. 10.2.3 is what I'm running. Mac OS X 10.1 did indeed do this- but not as much. I am finding that rather randomly, sometimes related to just a simple system restart, my SCSI CDRom does NOT work. Usually the little light blinks about once every second or more, but nothing. No CD. No mount. And yet. I restart- maybe it doesn't work, but, as I type, it just started working again... Anyone else experienced this sort of SCSI problem?? I haven't tryed my external devices yet.. But I can't go without knowing that my SCSI works as it is indeed most of the system on the desk (Tape drive, external HD's, etc..).. My system is timed to back the systems up at noon- I need to know if the SCSI is working or not..... Any suggestions on why my SCSI is semi-cutting in and out all of a sudden? Thanks, Keven Tipping |

Thankye all for the input. I decided to check out my SCSI Cable, for the internal drive.. Low and behold. A sticker, saying THIS SIDE CDROM ONLY.. Underneath the sticker was a hole.. Yup. The cable had been cut, not be me.. One of the cables had indeed been disconnected, I dunno why. So. I just moved the CDRom drive to the plug before the cut cable, and vola. Everything works just fine. The odd thing is that the Stock CDRom drive works just fine at the cut SCSI Cable end.. I guess it was some specail thing for that specific drive... Anyhow. No more MESH Errors, no more SCSI cutouts. The SCSI is working just fine. So is my External SCSI Bus- I guess this thing was screwing the entire SCSI over when it would crash the CDRom drives scsi... In fact.. SCSI is working better then 10.1. Now.. If only we could get the sound working..... |

Correct me if I'm wrong, but it's my understanding that SCSI devices must *always* be turned on when connected to your Mac... must be turned on before a boot, must be turned off only after a shutdown. Has something changed I haven't hear of regarding this "standard" practice? USB and FireWire don't suffer this problem because they are "hot-swapable," but I've never heard of this capability with a SCSI drive. tippingj, is your CD-ROM SCSI drive external, or internal? If external, is it turned on before you boot and only turned off after shutdown? Internal SCSI devices handle start up and shut down properly, but externals can suffer from the practice *variance* naturist suggests. However, if you use the correct procedure, it could be termination problems, SCSI ID conflicts, or cable problems. My internal SCSI CD-ROM drive in my 9500 works just fine in Jaguar, and my external SCSI devices (scanner, ZIP drive, etc.) work fine as well, but they remain always turned on when booting, and are only turned off after shut down. |

My internal SCSI drive on my 7500 seems unaffected. I have noted that 10.1 (my first install) on through the 10.2.3 all have made the CD-ROM a single-session device. I've a CD-R burner on the external SCSI chain, and it remains multi-session, and burns like a champ with one proviso: It must be turned on whenever I boot up or reboot, or it will not be seen by any app later. I can turn it off after boot up, but to be used at all, it must be on during boot up. My guess is you've got a bad cable or a bad terminator. |
