So I backed all my data up and did a clean install Friday night after purchasing Snow Leopard, everything was great up until Saturday evening after I got most of my applications and data restored by hand from my backup (didn't want any clutter from my old machine coming from my time machine backup). So now when I go to boot up my machine, it takes 1 or 2 minutes for it to boot up (up from the 30 seconds it was taking on Friday night), and when I copy data to my usb hdd attached to my airport extreme, watching to disk utilization, the data transfer isn't consistent, and constantly going between 15 MBs and 200 KBs, same story for Time Machine backups. I've ran a fsck from single user mode, and done a disk repair and permissions repair from disk utility. The fsck and disk repair reported no problems, although the permissions repair fixed several issues in the internet plugins folder, and had one issue in the system folder in couldn't fix. Does anyone have any thoughts, I'm kinda thinking it may be a bad hdd, but I'm not sure, I'll probably do another backup and reinstall tonight to see if something in the OS got messed up or if it's a faulty drive.
