I have seen people report similar problems with the following drives:
1 - Velociraptors (me/others) (don't work at all in raid correctly)

2 - Green Drives (search this list, there are similar problems) in Linux.
I have Caviar Black and WD RE3, they work OK in Linux.
OK, but:
1. Unlike the link you sent, there's nothing suspicious in any of the
SMART attributes on any of the four drives - no bad sectors or other
errors i.e. the following raw values are all zero on the WD drive which
I've been stressing:
Raw_Read_Error_Rate
Reallocated_Sector_Ct
Seek_Error_Rate
Spin_Retry_Count
Calibration_Retry_Count
Reallocated_Event_Count
Current_Pending_Sector
Offline_Uncorrectable
UDMA_CRC_Error_Count
Multi_Zone_Error_Rate
... as well as empty SMART errors logs.
2. A few failures were seen with the Seagate drives as well (see last
bits of the email), similarly with no apparent bad SMART attributes.
..
I have observed (and reported) the same issue in the past,
on Hitachi and Seagate drives.
The only constants seem to be libata and ICH7/8.
We must have a bug somewhere in there.
