Re: Slow Motion G4 After HDD Switch
- Original Message - From: Kris Tilford ktilfo...@cox.net Since the problem happens when booted in both OS 9 OS X, it's unlikely to be a software issue. You need to be thinking about hardware problems. Zapping the PRAM isn't always enough, you may need to reset the NVRAM by booting Cmd-Opt-O-F and typing: set-defaultsReturn reset-allReturn One thing that dramatically effects speed is the L2 cache. If the L2 cache isn't functional, the speed will be REALLY slow. The Sawtooth has a 1MB L2 integrated into the G4 module. If the L2 goes bad, you would normally see a warning when booting OS 9, and in OS X System Profiler I believe a bad L2 is shown as no L2 or 0MB? I reset the NVRAM and found the L2 cache in OS X to be 1 MB. I also ran Verify Disk in Disk Utility on the HDD and after 5 minutes it said all three volumes passed. But it is still incredible slow in OS 9 -- seconds to drag a folder to the Trash. I was wrong about the speed in OS X. Given the Sawtooth only has a 450 MHz processor I think its speed is normal. I ran the legacy software like PageMaker in Classic mode and all seemed normal. Perhaps a bit slower than native OS 9 before the HDD switch but no real hesitation in opening files or window, no ghost images when dragging windows around, and no hesitation dragging files and folders into Trash. The problem seems to be with native OS 9. Could it be some kind of OS 9 directory corruption? I have a pre OS X version of Disk Warrior but don't think it would be good to run it under OS 9 on a volume with OS X installed? I could try a clean install of OS 9 (ugh) or just run in Classic under OS X and re-managed the thousands of fonts-- not so bad and still fast enough for this legacy machine. Anyway, thanks Kris, I appreciate your time. AND From: Wayne Stewart waynejstew...@gmail.com How much space is left on your boot volume?

Reply should be ok to the 1st command, and a restart to the 2nd command. One thing that dramatically effects speed is the L2 cache. If the L2 cache isn't functional, the speed will be REALLY slow.

Bad RAM, or a bad HD, are other possibilities, but whatever it is, since it's happening while booted in both OS 9 and OS X, it's highly likely it's a hardware issue assuming that you've zapped the PRAM and reset the NVRAM. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
