Yes, but a second server beside it with 12 disks from the same batch hasn't had a problem (and the disks were inserted in arbitrary order). I am suspecting a PSU problem on the first server. After a couple of reboots the number of visible drives went down to 4, then to 0, then back up to 4. However I am remote from that machine right now. I'll get a voltmeter on it when I'm next there.
