Well I was using my MR-1000 in the field on Monday and TWICE got the "HDD Too Busy" error. I'm running firmware 1.51 so I was under the impression this was fixed.
Apparently not though.
Not to mention a bunch of skipping in one of the subsequent tracks. Not really a good thing at all. I love the sound of this box, but this has me just a little worried about its reliability.
