HR21 won't use eSATA (SIL5744, RAID1)

I'm trying to put together an eSATA RAID1 disk system for my new HR21. I've used an AMS DS-312 enclosure, 2 * Seagate DB35.3 750GB SATA 3Gb/s disks, and a 2m SIIG eSATA cable (though I've also tried the cable that came with the enclosure). The DS-312 uses a SIL 5744 chip, which is the same chip that is in the DS3RPRO that some folks have working. (So I thought this solution would have a good chance of working also.) I don't use any jumpers on the disks, so they are in 3Gb/s mode. The DS-312 also runs 3Gb/s on the eSATA port.

So, I restart the HR21, and disconnect power when the lights go out. I connect the eSATA and power up the DS-312. A short delay after the drive lights indicate they are up to speed, I reconnect power to the HR21. Then the "Almost there...a few seconds more" (yeah, right) screen comes up. During this screen, the DS-312's drive-activity LEDs light up 4 times, like this:

...about 5 seconds go by...
both drive activity LED's flash once (about .5 seconds long)
(a second later, I can hear the internal drive start up)
...another 5ish seconds go by...
both drive activity LED's flicker for about 1 second
...another 5ish seconds go by...
both drive activity LED's flash once (about .5 seconds long)
...another 5ish seconds go by...
both drive activity LED's flash once (about .5 seconds long)
(the internal drive starts making lots of seek noise)
(after a short delay, the screen switches to the "step one of two" screen)

I've tried a 2m SIIG cable and the 1m cable that came with the enclosure. Both seem to fit perfectly in the HR21 and DS-312, and both behave as described above. I've also tried reversing both cables, though both ends are identical.

I have connected the enclosure to my PC, though I can only do so with USB. :-( So, I cannot verify the eSATA is working this way. Ignoring that, the rest of the functionality works perfectly. The PC shows a 698GB RAID1 disk. I can partition it, format it, and check for errors (finding none). The PC likes it via USB.

(EDIT: bogus stuff about firmware deleted. The box already has the latest firmware for the DS-312.)

Does anyone have any idea what could be wrong? At this point, I'm thinking about moving to a DS3RPRO since someone has that one working, and it is almost the same feature-wise. It seems like the eSATA connection is working, due to the LED flashes, but there's no way to be sure. I wish the HR21 gave some feedback on what was going on...

Yeah, the DS-312 is hard to find even on AMS's own site. They also call it the "VENUS eS2". You can find info on it with a search on DS-312SUES.

I understand the eSATA isn't a supported feature at this time. I hope D*TV sees fit to dedicate a little bit more time to it, though, and at least provide some feedback messages, as suggested by Riot Nrrrd™. It could go a long way toward helping me diagnose problems myself, since this non-feature is self supported. (Well, plus the help of other users. :) But even if they don't do anything more, I'm glad they turned the port on. It gives me the chance of making RAID1 recordings even if I have to beat the HR21 with a hammer to get it to work.
(Uh, a hammer of loving caresses that would in no way violate the lease agreement, ahem.)

Yeah, I read all 18 pages of the working configurations thread before putting together my stuff. The MX1 is out for me because I badly want a RAID1 configuration to get some data protection. I've lost too many recordings to disk errors on the HDTivos. Like I said, I'll try the DS3RPRO next, since some folks have that exact model working. It just seemed like the DS-312 I've got would work since it is so similar to the DS3RPRO...

(Rant play) I actually hate all the enclosures out there (that I've been able to find). They are poorly designed for cooling. (Many are "good enough", granted, if you don't mind the noise...) For some reason, they think that the enclosure must have no more than 0.001" inches of clearance around the disks on all sides, and that the fan intake must be at least half blocked to work effectively. I've started thinking that, once I get a working system cobbled together, I may take all the electronics out of the enclosure and transplant them into something with about twice the volume running a quiet 120mm cooling fan instead of the 60mm whiners. There's no reason to hear the fan on any of these enclosures, and no reason the circuit boards, cables, and every other gosh darn thing inside the box should be blocking the fan intake to the maximum degree possible. (Rant pause)
