I findnothing in the manual about a different jumper setting for Bay 2. Theonly thing mentioned is that all drives should be set formaster/single. Any one know what's going on here?Rick RuskinHi Rick -Might be an incomplete mating of the caddy into the receiver.Possibly the drive 2 connector has shifted slightly out of alignment - it's hard tojudge by eye, though. The caddy/mating system has been somewhat notorious for notalways getting a perfect, solid connection. You could try loosening the mountingscrews inside the machine, sliding the mating assembly foward a touch, thenretightening.
(Beware cheap screws; use a correct screwdriver.) Could also be thatthe front panel frame is off just enough to prevent a full seating on bay 2.For many this has been intermittent based on several tolerances being slightly off.Many have solved this by putting small washers on the screws that tie the connectorto the caddy. The washers go between the connector and frame such that the caddyconnector is lifted out just a little more (single washer thickness is usually aboutright). This causes more full seating of the the caddy into the host connector.While I never had any connection problems with the drives on my HD24XR, I have donethe washer mod and all the caddies that have had the mod feel way more securewhen they seat.It's a great machine, with many good features for the money, but this part of itsexecution isn't the best. Be gentle with it, don't force it, but try giving it justa little help in this area and see if that doesn't clear the problem.Hope that helps,Frank StearnsMobile Audio-.DienerMusic18.10.08 18:48. You might want to visit the HD24 yahoogroup.
There are a few knownproblems involving the physical connection of the drive to the bay.One fix involves adding plastic washers to the caddy behind themultipin connector. Essentially the drive is not making full contactso it dismounts.
I've had problems with a particular drive/caddy, andhaven't been able to determine if it's the drive itself or the caddy.Sometimes it works, sometimes it doesn't! Also the HD24 appears toprefer some brands of harddrive over others. Good Luck!Peter Larsen18.10.08 20:29. Rick Ruskin wrote:I've tried all auggestions and nothing helps so far.

The only software I know of is the Alesis software.HD24tools from Mark Brovaart in The Netherlands. In some ways I don't like it aswell as the original Alesis software, but he does have a preview mixer, a way toselect what to transfer based on stop/start points, and a full suite of recoverytools should your HD24(xr) have an issue and mess up the disk. In over 10 yearsI've never had a disk issue, but it can be a disaster if you're recording and thepower glitches (I.always.
have my machines on a UPS), or if you're in a super loudenvironment and the drive hiccups from vibration. (Thankfully, I never do that kindof work.) In either case, HD24tools has methods and tools to recover that data.And, the transfers are blindingly fast. As noted, at least twice as fast as theAlesis software.That is extremely cool. I work often with a guy who uses the HD24 and I don'tthink he knows about this yet either, so I will definitely prod him about it.I'm also pretty sure the original poster in this thread doesn't know about itand would benefit from it too.-scott-'C'est un Nagra.

But, unfortunately, at 8-10x the price of the HD24XR, and with a muchlarger footprint. But that's understandable; the Radar had a real editing systembuilt in, not the clunky 'toy' editor in the HD24XR.
(Meant nothing to me, though;always edited in the DAW.)While I've not personally done the shoot out, multiple sources report that thelater-generation HD24XR was on par with the Radar sonically.

On your FOH console pick up your analog direct outs, insert loops, or moreideally, your Dante data, and away you go. But also a little pricy at $4K andwhatever version you bought (some version of analog in or some version of digitalin) you were stuck with. The HD24XR could do, in channel pairs, analog or digitalin - and be had new for $2K.

I'm not convinced that a good laptop plus an 8 ch interface with Lightpipe and 8 channels of Lightpipe A/D isn't better, simply because it has a full display.If you needed 24 channels, or even 9 channels, would that convince you?What's attractive about a stand-alone recorder for situations where youonly need capture is less haywire. Your laptop computer with aninterface and A/D converter is three boxes with a lightpipe connection(two if you want to run at 96 kHz sample rate as many do these days)plus USB or something similar to get from the computer to the interface.More boxes to fall off the table and more connections to come loose.That may not be a big deal when you're setting up essentially a controlroom at a remote location - you have a certain amount of control overwhere you can put things and who wanders by a little tipsy and jostlesyour stack of gear. You could do a little damage control by racking upthe interface and converters so you only need to connect the analoginputs (you'd have to do that with the stand-alone recorder anyway), andhave just one cable going to the laptop computer. And while you have abuilt-in UPS for the computer, you don't for the interfacing hardware.The TASCAM X-48 is probably the most advanced of the dedicatedmultitrack recorders.

If you needed 24 channels, or even 9 channels, would that convince you?It might, if you really need 24 for live audio capture.24 is not very many channels. Often if there are multiple acts, they'llsplit the console up so that the first act gets the first 24 channels andthe second act gets the next 24 channels, so that both can soundcheck beforethe event and be set up. Digital stuff has reduced this a lot, but evenin the digital world it often continues so that each band can be preset intotheir own snakes.Then you get events where you have the console split into sections or youhave multiple consoles. I'll often work gigs where I am mixing an orchestrafeed while the guy to the left of me is mixing some jazz soloists and theperson to the right of me is mixing the narration and effects, all windingup as part of the same 2-bus at the end.The thing with both of these kinds of gigs is that there aren't a lot ofchannels being used at the same time, but there are a lot of channels outon the board.
So if you have a guy in a truck handling the record feeds,he can repatch everything at every set change so that he gets everythingactive in that set to tape without any of the other stuff.The whole point of these portable recorders, though, is to just run everythingto media and not need the guy in the truck repatching. So it's not unusualfor a larger festival stage to have three or four Joeco recorders racked uptogether.At 1U each, four of them still take less space than a DA-88.
