I got a problem with my Mac Pro 4.1, when I turn on the mac the chime sounds after 20 - 30 secs and later on the white or gray screen appears. I had reset the PRAM, changed the coin battery, tested with the "Apple Hardware Test" (no problem at all). I have 20Gb (4X4GB, 4X1GB) of Ram, five hard drives attached to it. I thought that the problem was the hard drive with the OSX (10.8.2), got changed with a new one with a new OSX on it, two hard drives of 2Tb with RAID "lvl 1", two hard drives of 640Gb. When my mac goes to sleep, sometimes when I try to wake it up I hear the sound that wokes up but got no image on display, so I have to force shut down and then turn it on again.

 

I try dettaching all the hard drives except the one that has the OSX, thought it might be problem of the RAID. I did experiment that my mac freezed and then restart.

 

Please someone help me with this problem!

 

Specs Mac Pro 4.1

- 2.26ghz x 2 "8 - core"

- 20gb ram (I recently upgraded my ram from 6Gb)

- 1Tb HDD

- 2Tb HDD x 2 (RAID 1)

- 640Gb HDD x 2

- NVIDIA GT 120 x 2

- OSX Mountain Lion 10.8.2

 

 

Sorry for my english that is not so good.

    10.8.2 does not like 2xGT120s

     

    Mirror RAID is of dubious value.

     

    Normally system maintenance as in Safe Boot, repair directory, etc.

     

    Power Management (sleep, power on, etc) are getting to be more common but on 2008, not 4,1 2009s.

     

    Force Shutdowns WILL corrupt the boot directory.

     

    Clone or do a clean install and test your system with just Apple Mac OS basics.

     

    And of course you bought ECC certified for Mac Pro DDR3.

    Snow Leopard seems to be the most solid OS.

     

    SSDs can be iffy.

     

    Anyone's RAM can cause or be a problem.

     

    But you said it started before those.

     

    "problem with the hard drive..." is too general and really rare. You would have to have bad sectors or something and not been able to map those out. Any drive can ship that way (not just mapped out at the factory). Zero all from Disk Utilty is not guarantee to resolve those.

     

    Also rare to have a clone not work, SSDs being likely candidate and finiky.

    Permissions in your case are basically useless. I was talking about the directory that you are corrupting over time.

     

    There are too many threads about SSD  - they work is all you need - by goodness goes back 4 yrs already using SSDs of all shapes and sizes.

     

    I never put Windows on same drive as OS X.

     

    Reset the control panel in Windows or Mac for Startup Disk and make sure it is set to what you want (move away and back even).

     

    If you have Lion, use Recovery Mode. If not, boot off a clone. If not a clone, make a small 30GB emergency Mac partition - on another drive (timemachine is actually useful place).
