It sees boot drive only - original 320GB drive. The drives are 2 x WD 1 TB Caviar Blue, 1 x 640GB Caviar Black. Please help.
Mac Pro, Mac OS X (10.7.5), 2.8G Quad-8GB RAM
In what context? Do they appear at all in Disk Utility? Are they formatted?
Have you tried physically swapping the boot drive with another of the drives to see if the bays are at fault?
Matt
Have not swapped boot drive to other bays. They are not recognized in Disk Utility. Context, I want to install a new HDD, clone my boot drive with Bombich Carbon Cloner, and get more space and newer drive.
If the Bays are at fault - what if anything to do?
Michael
they are raw disks, not formatted.
Michael
shut down, moved Boot drive to bay 2 - computer did not see it - go the big "?" on startup. didn't try other bays. seems odd that the bays wouldn't be recognized. If that's the case, is there an easy fix?
Thanks,
Michael
So these drives
Where did they come from?
Nothing on them?
They are not the more popular Black except the one 640GB which is no longer carried but use to be and all are SATA II drives.
The 4,1 2009 Mac Pro (not yours) will not accept really old SATA 1.0 drives.
When they won't show, you either have a motherboard problem or the cables to the drive bay. And you never used another controller, like Apple Pro RAID.
Moving drives is a bad idea except to see if one bay does have a loose data or power cable going.
2009 introduced new size drive sleds so moving a drive from 1,1 to 4,1 with same drive sled would not work.
Trying it in a FW800/400 case of course 'might'
seeing they never were initialized, and where did them come from, ship 'em back!
The alignment system in the Mac Pro relies on your tightening the screws with exactly the correct size screwdriver, and not over or under tightening them. There must be no gaps between the sleds and the drive, except that filled by the cushioning washers.
When inserting the sleds, it is crucial to capture the leading edge of the sled under the first set of metal roof tangs, or the alignment further back will not be accurate. A bright light and lying on the floor looking up at the bays may be required if you do not do this every month.
Can't get my MacPro to recognize additional internal drives.
