I had three of these drives in my TS-459 Pro+ but eventually retired them after reading about the problems with them on here and other places. It was an expense I didn't want to incure, especially as I came just as drive prices started to increase, but came to the conclusion that fairly soon one the the drives was going to fail. I'm now glad I did.
I now use them for NAS backups in conjunction with an eSATA enclosure. Two of the drives still work fine but one has recently taken to going offline at random. It can go offline while under load or at idle. The only way to get the drive back online is to power off and on again. (Same effect as pulling the drive and reinserting.)
Out of curiosity I reformated the problem drive to NTFS and started to use it with Windows 7 64-bit with an different eSATA enclosure. Initially it worked fine but soon started to go offline again. I then reformatted the drive back to ext4 and tried it with a Fedora 16 with the same results.
This problem drive passes SeaTools tests and the only anomaly in the SMART data is the Power On Hours that are about three or four times more than they should be. (The Power On Hours on the other two drives are also about three or four times what they should be.)
With the best will in the world I don't see how a NAS firmware update can fix a problem with a drive that takes itself offline at random where the problem is with the drive itself.
