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.


Thanks,

Tim.
