Quadra 700 & SCSI2SD freezes

[james_w]

I'm having a strange behaviour (just started recently) with freezes on my Quadra 700.

The first time it just happened whilst I was using it, and the segment of the hard disk that identifies itself got corrupt. Disk First Aid fixed it fine.

Then startups were being weird. So I ran Norton Disk Doctor on it, which found a bunch of errors, but it fixed them all and now startups are fine.

What happens now is that it freezes when I try to restart or shutdown the Quadra.

Starting up, then shutting down from a different disk whether internal or external is fine. They're both running 7.5.5.

The shutdown freezes happen whether the SCSI2SD is internally mounted or in an external SCSI enclosure.

Any ideas folks?

Forgot to mention, I also updated to the latest SCSI2SD firmware (I was on 3.6) and it's the same.

Are you using Sherlock to speed up file searches? The older version of Sherlock corrupts the file structure, best to find the extension and remove it.

 

[TheWhiteFalcon]

Sherlock isn't in 7.5.5...it's not even 68k compatible.

I should mention also that I've swapped out the PSU and logicboard and it behaves the same (at first I thought it was maybe faulty SCSI controller).

The next thing I'm going to try is a fresh system install on a different SD card

i would say hit it with lido7 ,  nuke drive make new partitions, don't exceed 1.7 gb each. re-install 7.5, and you should be fine.

Yeah, make sure your partitions are under 2GBs.  That can cause all sorts of weird problems.

 

[james_w]

Thanks very much - I used Lido to format it in the first place, but my partitions are 2gb, I'll backup, initialise and then make smaller partitions and try again.

 

[uniserver]

yeah i always had good luck with 1.7 gig partitions.  seemed to get issues when i went over that.   

 

[james_w]

Frustratingly that doesn't seem to have solved it (now have 2x ~500MB partitions and 2x ~1.4GB partitions).

Not sure what to try next... maybe a reinstall of the system software?

 

[uniserver]

nope i have no idea it sounds strange.   maybe talk to mike and see what he thinks. doesn't he offer support for his products these days?

 

[CelGen]

Have you tried a different SD card? You could quite simply be running up against a bad card or a cheap card that isn't rated for the task and blocks keep going bad.

 

[james_w]

Yeah good plan - I'll try a different card before bothering Mike thanks again folks

 

[james_w]

I tried a different SD card, 2gb and also not SDHC.

Split into two partitions and still the same issue. It seems it does it on 7.5.3 or above for some reason.

I've installed 7.1.1 instead and it seems happy.

Going to try another fresh install of 7.5.5, but just do things bit by bit so I can try to identify what might be causing the problems.

 

[uniserver]

this is interesting and something you want to keep an eye on.   there might be a bug in his firmware.

 

[james_w]

I've now also done a fresh install of 7.6

Still is 100% happy on 7.1, but freezes when trying to shutdown or restart from 7.6.

It's not too serious for me as I can just hit the reset button on the front and most of the time I run 7.1 anyway, but be nice for it to work in 7.5+

 

[james_w]

If I get time I'll try a vanilla 7.5 install but can't find my installer right now

I've had weird SCSI stuff on my Q700 under 7.5.5 as well, mainly with the external bus.
