Recently purchased QuickSilver w/Tiger OS. Oddly, when booted in Tiger, one of the three volumes on a firewire drive will not mount. When booted in Panther, the volume mounts with no problem. Disk Utility within Tiger will not mount the volume. DiskWarrior 3.0.2 rebuilds the directory but says a Macintosh services error keeps it from replacing the old directory. DW says boot from the CD and rebuild again. I did that with success, but the volume still will not mount under Tiger. This does nothing to boost my confidence in Tiger; and I was skeptical about it to start with. From the little I have seen of it, I see NO improvement in performance over Panther. And it is not as intuitive or as user-friendly as Panther is. At least, not in this brief window of exposure I have seen. For the heck of it, I'm going to backup the Tiger-unmountable volume, erase it, and restore it--just to see if that corrects the Tiger hiccup. Meanwhile, has anyone else had this same problem with Tiger? BTW, I have an identical FW drive of 3 identically sized volumes that DOES mount under Tiger.
