Seagate announced a problem affecting some of their 3.5" disks. The affected models have firmware SD04 or SD14. The serial number of the impacted Disks will have a numeral different to the 3 that we have put in bold:
1000 Go ST31000340AS
750 GB: ST3750330AS
500 GB: ST3500320AS
The bug causes a partial recognition of the disk cache resulting in malfunctions.
An update is available via a bootable disk image. Although intended for PC, it should work on the Mac Pro:
AD14-AllMoose.zip
Once the archive is downloaded and unpacked, you should use disk utility to burn an iso image to a CD and reboot.
We are still waiting Apple and Seagate's postion on the large number of defective 2.5" disks that were mainly found in the laptops and Mac mini.
