I've upset the scsi gods!

[vassilizaitsev]

I got an 840av... swapped bits from an old one and got it working...

But now it's not working, well it mostly is...

I seem to have upset the scsi gods.

It was using the hard drives fine, but now it wont use the hard drives.... when I go to drive set up (off 7.1 install floppy Or 8.1 os install) I get the message that there are no suitable scsi drives!

So I can get the floppy drive, & I can get the cd-rom drive & I can get my external CD-R drive.

But when I try a hard drive, it wont recognise it... I wont recognise the two drives that I origionall had working, it won't recognise another drive that I've since put in & it wouldn't recognise an external hard drive!

I'm not sure what I can try next... & why would it recognise a cd-rom drive, but not a hard drive...

It sounds like you have a SCSI ID issue (assuming I've interpreted what you said properly). If that's the case, you can usually fix it by changing 3 jumpers on the back of the hard drive. There is usally a label somewhere on the drive that shows which 3 jumpers are for the SCSI ID. The configuration should look different from all of the other devices on the SCSI bus.

Oh, and how dare you bring the wrath of the SCSI gods down upon us! Now half the members of the forums are going to have to reterminate their SCSI busses.

I got the 840av working and had two hard drives... a faithfull 4.3 gig and a 1.2 Gb.

But the smaller drive kept on being there one time, but then not being seen the next. So I assumed it was a jumper issue, so I changed my jumper, and now no hard drives can be seen !!!!! wahhhhh

Well I'm gonna have to look at the third drive, that I am now looking to try to get to work (not trying to use three drives, just trying to get one drive working), I'm gonna have to think about looking at it's jumpers...

but it's just so bizzare cos the computer will see the cd rom, but not the hard drives...

perhaps somebody will re-engineer an 840av clone and give it modern interfaces....

Get "SCSI Probe" onto the case. It will tell you exactly what the computer is seeing.

I've made some progress!

Well, I cant get the internal scsi, but I have an external cd-r and an external hard drive & am booting os 8 from the external hard drive.... but when I put a cd in the cd-r drive, it isn't mounted on the desktop.... now usually I'd just install Toast, but Toast is on a cd.....

… I have an external cd-r … but when I put a cd in the cd-r drive, it isn't mounted on the desktop …

If the 840av is indeed the successor to/baton-carrier after the 950 it may well have both internal and external SCSI buses. While, theoretisch, the two should be independent, is it possible that your CD drives and HDDs with common SCSI IDs are conflicting? That could be the source of the failure to be visibly 'mounted' on the desktop. More so if there is but a single bus for internal and external daisy-chains. Failing that, are you the victim of termination or termination-power problems? Both contingencies are worth your looking, if only to exclude them.

Progress is that..... a cd did become mounted on the desktop... at least, ones that boot automatically seem to mount, and after installing Toast I got one of my own burned cd's to mount... it's half a solution and as much as I can hope for, well, I'm all set to go, just need to attach the video cables...
