                        <content:encoded><![CDATA[Ok, update: Another drive hung during use today in the same enclosure as previous instances. The light stayed ON, at least for a few minutes until I got the following dialog from SoftRAID:

"An error occurred reading the partition map on a disk. This disk hung during a read. This disk should be replaced. You may have to restart your Mac before this disk will respond again. Disk with error: disk 7, SATA bus 0, ID 7 (Thuderbolt), 6 TB" (see attachment)

The light blinked off after this message appeared. After that, as usual, I unmounted the volume, switched off the Thunderbays, restarted them and SoftRAID did a rebuild.

So is this an enclosure issue or what?]]></content:encoded>

                        <content:encoded><![CDATA[I should clarify what I meant in my last post:

The problem is currently affecting drives X and Y in Enclosure A, bays 2 &amp; 3. If I swap those drives into Enclosure B and the problem persists with drives X and Y, now in a different enclosure, then the issue is likely specific to the drives themselves because the problem is following the drives.

But if I swap drives X and Y to Enclosure B and the problem persists in the same bays of Enclosure A, now containing different drives, then the issue is more likely related to the enclosure and not the drives.

Does this make sense, or am I missing something?]]></content:encoded>

I actually hadn't considered switching ports, although that's not a bad idea. I just meant trying to isolate the problem by putting the affected drives (it seems to be the same 1 or 2 each time) into my other Thunderbay (I have two in a RAID 1+0). If the problem persists in that case, then it's probably not the enclosure, right?]]></content:encoded>
