A1200 crashes with PCMCIA transfers

[chocolate_boy]

I've noticed my A1200 will crash whenever anything is copied over PCMCIA now. This can be a CD-ROM over my Squirrel, or a CF Card over a PCMCIA adaptor or downloading large files from the net over my cnet card.

Any ideas what this could be? Transfers begin, followed by a guru straight after (8000 0004)

HDD max trasfer, wrong setting?
What about your workbench stack? its default is something stupid.

Failing power supply?

Using an 8mb upgrade that isn't pcmcia friendly?

But the card would'nt show up at all then.

Turned out my DH1 partition had become corrupt, copying any files to it crashed the machine, and as since I was trying to download files to it and copy to it, that's what was causing the crashes.

Copying to DH0 or RAM didn't result in a crash, so I've formatted and restored DH1 and no crashes now Thanks for the tips anyway.

I never had a partition crash the computer.

Is the harddrive bigger than 4 GB?

It's a 4 gig CF card split into two 2 gig partitions. Sadly the problem has come back!

The disk claims to be 50% full with 980meg in use and 980 meg free, but it's not that full, copying to it was fine until all my files were back, now copying crashes the machine again. Very strange.

Maybe a slow format is needed or could it be a transfer speed issue?

You should keep your boot partition around 500MB's to be safe and never full format, only quick format.

Try doing this;
500MB BOOT PARTITION 0
1.5GB PARTITION 1
1.5GB PARTITION 2

That should keep it under all the limits.

Guess I'll have to transfer the card back to the PC and rebuild it then, three formats and same issue with DH1: Oddly DH0: is same size and works fine.

thanks for the help.

I have an ACA 1230/28 so I guess that is ok? It has around 64 megs onboard ram.

Yes, the ACA is PCMCIA friendly although some brands of CF cards are known to have issues with the ACA and also the ACA's do not function correctly with all A1200's, if you A1200 has timing issues this can also cause strange errors.

FOL should be able to explain more, I sold my ACA becuase some of my hardware (such as PCMCIA adapter and FastATA) would not work with the ACA1230 on my A1200. Everything works fine with my Blizzard 1230MkIV though.

All the best,

Steve.

Steve it correct.

I have had the PCMCIA slot taken out by ACA cards, due to timing.
You apply the timing fixes, then it start working.

Its hard to judge though, as every board seems different.
Say you had a REV 1D4 which works fine, then you could have another 1D4 that doesnt work. The boards can be identical, but one can have timining issues.

Its also a one way street, most boards, you do fixes for ACA cards, then the board may not work with other Accellerator cards.
