I keep getting this message "GVP SCSI device: 006, unexpected status, $45/$49". I've changed boards, computers and hard drives and still get this message, usually followed by the message "DH1 has a read block (or checksum) error at block #####." (I think this is a false message because it doesn't appear unless the other message appears. This is true whether I reformat the drive or not – I have done both.) It does not happen every time I use the system. Sometimes it will run for a while before the error shows up – other times it will appear as soon as I start an application. The configuration is: Amiga 4000/040/14 meg. RAM 120 meg. IDE HD – Seagate 345 meg. SCSI HD – Maxtor (7345S) – Device 6 – J302 (Power-Up Option) Removed GVP A4008 Impact Series II SCSI Controller FAAASTPREP V2.07 Video Toaster 4000 Y/C Plus Bernoulli 150 Transportable – Device 3 Syquest 88 – Device 4 Sony CDU-541 CD-ROM – Device 5 – DC OFF in user startup gvpscsi device in expansion drawer and in user startup I talked to Maxtor and they suggested I pull J302 because, they said, the GVP board wants to power up the drive itself. I pulled it but the problem remains. They then suggested that I try a low level format on the drive. I did but the problem remains. They now think the problem is with the GVP board. I have tried other A4008 boards but the problem remains. I've moved everything to another system but the problem remains. I've reloaded all software but the problem remains. I have the same problem in another system with the same configuration but not as often. I have been using this configuration with a Quantum 525 SCSI HD for over a year and not had this problem – it is only happening with the Maxtor drives. I'm using these systems in a production environment and these breakdowns are costing me money, please help!

I'd be interested to learn the answer to this one as I've got exactly the same problem with a Maxtor and an A1291 GVP SCSI I/F which I posted here last thrusday and haven't had an answer to. In the mean time, I've returned the A1291 because I've had problems with other devices too and am hoping to get the replacement this week. Kevin Flying AutoPilot from Surrey in the UK

Jon, These messages typically indicate a cabling and/or termination problem on the SCSI bus. The final answer may be anything from changing the termination on one of the units, changing the order of the units on the SCSI chain or changing the cable lengths. Experimentation is the only way to get to the right answer. You could also try turning off disconnect for ALL of the drives. GVP TECH

-Active Termination- Has anybody tried an active terminator (these are NOT the normal passive terminators and cost FAR more, usually around $50-75 each) with an A1291? One thing makes me think this might solve the "Unnexpected Status" problem (which I have too) is that in the A1291 manual, on page 3.16 it mentions that; "The A1291 SCSI Kit uses 'Active Termination' to constantly (and dynamically) adapt to the changing termination needs…." I'm gonna try this on monday night (as I've got these terminators at work) but if somebody has already tried, let us know the outcome so I don't waste my time 🙂 Kevin Flying AutoPilot from Surrey in the UK

Jon, I had this problem when I added a CD-ROM drive to my GVP SCSI-2 accelerator & HD. When I checked Disconnect Off on my hard drive using Expert Prep, I didn't get the unexpected status message anymore. Perhaps you should try turning DC off on your HD device 6. jf – lamplight productions ~~~sailing on autopilot~~~

If GVP Tech responds to you via e-mail please post the solution. I just installed a G-Force 040 33mhz board in my A2000 and now I get those same types of errors. Unexpected status $40/$49 Device 002 – a syquest 44 meg, and also on device 003, a syquest 105… Interesting that I don't have the problem with the quantum…

Have you tried the disconnect off command? Some drives support it, some don't. Your Quantum probably does, your syquests don't. Gary on AutoPilot from Charlotte, NC
