hdb irq wait errors.... - 05/12/2006 12:53
Just tried this AM to sync some new music to the player, and I keep getting hdb irq wait errors. I suspect, perhaps, hdb is dying? I have (2) 30GB drives, but only ~15GB of music. I upgraded a while back from the original 10GB drive.
Is it possible to remove hdb without rebuilding from scratch? I have backups of (most) of my music on PC, so even if I had to trash most of all of my mp3's, it wouldnt really matter.
Can anyone outline a procedure. Oh, Im running V3a (the latest one) with Hijack as well.
On a side note, are there automotive-spec hard drives yet? My original model would boot to -20F, these will not boot below ~30F, and I suspect that may be part of the reason for impending failure...

Heheh... Yes, I know there are solid state drives... For about a gagillion dollars/pounds/euros.... (for any reasonable capacity). I thought that Seagate or someone had been experimenting with some "automotive spec" drives - i.e. lower temp, additional shock protection. I can't seem to find any info about them.
Anyway, I took the advice and ripped apart the player. I pulled out the IDE cable, and looked closely (while flexing) and lo-and-behold, it's not crimped all the way. Close, but not all the way. So I set it on my desk, and re-crimped it using a flat object and my own weight. I did all three, and they are very crimped now :-)
Back in the player, and after a lengthy media check, NO irq errors or HD not found messages. THANKS. I had read that FAQ before, and even 'checked' when replacing the drives, but unless you REMOVE the cable and really look, it looks fine....
On a side note, it would be "cool" if we could replace hda with a low-capacity (whats the minumum needed?) flash drive, and have the player still "work" (sans mp3s) if hdb failed to spin up. Since I use the empeg for radio as well, when its down, Im in silence....
Thanks again, and thoughts on that last paragraph?

Mark,
Wow, if you manage that I'll be kicking myself for not buying a few 2GB CF cards for $20 each on "black friday" a few weeks ago. How much space does the base install need? Would 1GB be enough? 512MB? I looked up these adapters, seem to run about $15 unless you have a better supplier.
Looks like those seagate ee25 drives are ~$130 for 20GB, $147 for 40GB... Not THAT bad a deal, when you think about it. -30C - +85C OPERATING range, with lots of shock and vibration protection.

Wow, cool. So an old 64MB CF would even work. I think I have at least a few of those sitting around... I wonder how fast the CF would wear out....

Okay, I *work* here and I didn't know about ReadyBoost.
I wonder how one activates that sort of thing. Hm.
Thinking about it, I'm not sure I'd want to use it, though. From its description, it sounds like it's using flash RAM as a sort of intermediate or extra cache, as if it were a memory subsystem with a response time that falls somewhere between RAM and Disk. Clever idea, except for the part where flash RAM is limited in the number of times you can write to it. Since RAM caching does a lot of churn, you'd be burning out your flash card as you used it (a lot more than just loading pictures or MP3s would).
I'll do some research here about it. If I find anything interesting, I'll report back.

Just wanted to pop this back to the top for an update. I happened to pick up a seagate EE25.1 series 40GB drive (real cheaply too ...) Supposed to be good to -40F. My current set will not boot below ~12F. Its now 3F outside....
I'm going to install it as HDA once it comes in. I think I should be able to fit almost all my music on that one drive, until I find another one...
I wonder, what would the expected behavio(u)r of the empeg be with hda working and hdb "out to lunch" due to cold?

Very hard to predict, really. Depends a lot on how the digital part of the controller deals with the cold - it might basically lock the bus (preventing hda access) or might just appear to not be there (which would be fine).
Got a freezer?

Yeah, I have a HUGE freezer, just outside the building :-) The high temps for the rest of the week are in the teens F, with lows around 0F....
