Hi everyone, I'm hoping someone can answer my questions. Here's my story. (Stats: Original Quad Core Mac (2 x 2.66 Intel Xeon) - 9 GB RAM - SL 10.6.3) My Mac has been running very, very slowly lately. Spinning beach ball for 45 seconds for no reason and then everything will happen at once. Copying a 25 MB file can take 1 minute. Starting up used to take 25 seconds, now it's 4 minutes. It seems to come and go a bit. I've been using Macs for 15 years and I did everything I could think of. Disc Utility. Observing Activity Monitor. Trashing prefs. Zapped PRAM. One of those helped a little, because it's not as bad but still slow at times. * One thing to note, I made a new account. It was really fast. Just like a new install. I booted up from DiskWarrior4, when checking my main startup disk, there were around 50 something "disk malfunctions" and I could not replace the directory. The only option it gave was to back stuff up. But on the contrary, DW4 hardware test said that it's SMART status was OK / verified. MY OPTIONS What should I do? 1) Backup everything, but do nothing and hope it speeds up. (It's getting a little better since I cleaned it out) I use Pro Tools and Logic and it would take a long time to reinstall everything. 2) Back up everything, erase the hard drive, and reinstall the OS **on this same drive.** I'm actually broke right now and do not want to buy another hard drive. Would this be stupid because DW4 reported a hardware error and I'd just be getting in the same mess down the road? 3) Back up everything, buy a new hard drive, start clean. This is probably the safest option, but I really only want to re install everything if I have absolutely have to. Is there any chance that DW is reporting incorrectly, that it isn't a hardware error? It's a new-ish Seagate Barracuda 500GB, 7000 RPM. Would do you think? Anything I'm missing? Thank you very much.
