Hello all,

My new Mac Pro is crashing, 3 times in the last 12 hours. I come from a Windows background so this is new for me :) I am currently running a hardware test, but was wondering if anyone here can help.

Time machine runs every hour.

What tell you guys its the file system? (Just trying to learn to read Apple crashes)

mainly the

"hfs_UNswap_BTNode"

and the whole bunch of other HFS things popping up.

i just took a guest to be honest haha.

maybe delete your time machine backups and start those again aswell..
 
You wouldn't normally see a kernel panic because of a file system on a hard drive unless the drivers for the kernel were corrupted. Because of that, I am thinking either the Install is toast and the system needs to be reinstalled, or the hard drive is dying. I would run your hard ware test, and look at reinstalling the machine.
 
Does it only panic if the system drive is failing? I have 4 drives including one external that is used for time machine. Would the system panic if that drive was on the way out?

no it can panic from many things, driver issues, peripherals and just random problems that havent been fixed yet, however reading from zmttoxics its unlikely that there is any problems with the file system and more a HD problem or a kernal problem.

is your external HD a lacie brand of hard drive (the external one). how is it conencted?(firewire/usb?)

i have experienced kernal panics with my LaCie, it didnt cause any problems i just lost work because of it :(

Well, we are in the unix world here. The platform is modular almost, designed so that you can have many failures in the system and still have it running. If you are seeing kernel panics, its usually related to a bad driver or a hardware fault. The only drive to be suspect here is the boot drive, because if it was a non primary drive you would get logs about it - not kernel panics.
 
Thanks guys.

The external drive is a Maxtor - it has already been back once for a failure.

I will report back what the hardware scan shows when I get home from work. If it is the boot drive I guess I will be on the phone to apple.

USB drives are terrible for permanent storage - can cause all kinds of bus issues (I've seen them destroy USB controllers). It would be a good idea to take the usb drive offline and see if that helps.

aahhh ok, it could then be the external backup drive then. i would sure hope that its not the boot drive, at least you have a backup!

ohh yes they are the worst. i had my itunes library on my external USB and it would spin down. if i paused a song and then let it spin down and want to play the song again it would cause a kernal crash. it took me a good 5 goes to figure out what was causing it!!!

FW ftw :)
 
Just an update.

I ran disk check and the external drive crashed the system right away. Boxed it back up, for the second time, and turned it in for another internal.

Problem seems to be solved.

Thanks.
 
The purchase took place like 2 years ago. They still sell drives with the Maxtor name for some reason though. Must be because of some terms with the merger.

Congrats on resolving the issue OP. :D
