Old problems are not addressed by Seagate for months . All the recent 'cudas have problems no matter the drive or firmware version. We have filled a support request on Seagate's CSO Customer Portal... not really helpful Internet is full of reports about the drives being buggy and the support staffers being unable to help. They should be ashamed... We have filled a request to return the discs to our vendor... Good day,

Internet is full of reports about the drives being buggy and the support staffers being unable to help.

They should be ashamed…

We have filled a request to return the discs to our vendor…

Not sure about the 1.5 TB not having an enterprise version. Will check. On the RAID qualification, people were seeing problems with single drives, never mind RAID. As of today, it appears Seagate has admitted to the problem and is preparing a patched firmware. Their responses as seen in the Seagate fora were ... well ... unfortunate. Seatools isn't Linux, but Seagate's, quite a few of them, do happily provide storage to Linux. If Seagate just isn't interested in this, I wish they would let us know. We use and like their kit. And we use them for Linux. @Brian Possible. We have had problems with hardware raid with the SN05 firmware. The SN04 firmware was a little better. What controller are these plugged into? We have seen some SATA controllers not behave well. Also, if you get correlated simultaneous "drops", then you might be running into power as an issue (power supply rails can't handle the load for some reason). The issue we have seen is the (extreme) sensitivity of the unified controllers to timing, and the somewhat lax(er) SATA drive timing result in timeout issues. This is not to indict SATA. This is simply to note that the unified controller concept, while cool, has some ... well ... more exciting features. @Chris Hope to see you in Austin! I'll come by your booth at some point.

I have had problems with my two 1TB (Linux software raid 1) "disappearing" both exactly at the same time at random spots when trying to transfer DV data using dvgrab. See for details. I don't think it is a hardware fault, but maybe a hardware bug? Brian May Hello,

((BTW isn't the word "desktop RAID" a funny creation ?)) Most RAID-vendors don't even start qualification tests for non-enterprise drives.... - you probably know now WHY :-) Unlike with the previous Barracudas – like this example:
Vendor: ST350063 Model: 0AS (desktop)
Vendor: ST350063 Model: 0NS (enterprise)
…the current 1.5TB drives will not have an ‘enterprise’ equivalent.
