Macbook Pro Model 5,2
2.8 Ghz running 10.6.6
I installed some drivers a year or more ago for a Maxtor OneTouch III (an external hard drive).
This includes:
MaxtorPowSecDriver.kext
IOFirewireMxBt.kext
MxBtDaemon and associated StartupParameters.plist
I have a feeling that these drivers are now not needed and causing severe system problems. I attempted to connect a backup drive to access some info (which I haven't done in a while) and noticed it consistently freezes the kernel. This is mainly a Firewire issue, but the USB port has shown some consistent problems also. I originally noticed the problem after 2 of 5 of my Maxtor drives (being used as a NAS through the iMac) were all plugged in, but started disappearing over time (drive just not showing). I thought the drives or their power adapters went bad, but then after fiddling with the power adapters was able to determine the drives themselves were not bad.
I decided to plug in my MBP to use a different machine to further diagnose the problem. Thats when I realized there was a major non-drive problem. After I plug in the Maxtor OneTouch III drives into the MBP I am either a) forced to both reboot by holding the power button to shut it down or b) the drive does not show up at all, however the lights on the drive do blink. Again this is also occurring on an iMac that has the same Maxtor Intel Update drivers.
I removed the drivers listed above, but am still having issues. I was able to snag a Macbook (non pro) and use a Firewire 400 cable. The drives immediately came up without hesitation. This machine has all stock drivers.
Here's a link to the update that was applied:
http://www.seagate.com/staticfiles/maxtor/en_us/downloads/OTMacIntelUpdate.dmg
Can anyone explain how to fix this without doing a complete reinstall of the
OS? Also, does my diagnostic seem correct 
Thank you!
