CF card as a swap drive gives write errors

I'm using a 256 MB Transcend CF card to swap stuff from PC to A1200 via a PCMCIA
adapter. It's formatted FAT32. My old Retro Athlon running XP shows no errors on the
card, but *every* time I try to copy something or lha x something on Amiga, I'm given
loads of write errors. Since my DF0: is broken, this makes file transfer a bit tricky. The
card shows ok as CF0: on activation.

Have you set max transfer correct on the Amiga side?

Maybe you PCMCIA port is damaged? Bent pin maybe?

There is no max transfer involved on PCMCIA port.

There is for sure. Every DosDriver has a MaxTransfer parameter. But compactflash.device should be able to deal with it.

Okay, I should have said: There is no maxtransfer problem on the PCMCIA port.
Notably, the CF0 dosdriver has no maxtransfer parameter.

I think Fitzsteve accidentally recalled the IDE maxtransfer requirement which isn't required for the PCMCIA port in this case, as mentioned above.

Are you using the latest CFD (Compact Flash Device) from Aminet or the older version. The new one is meant to have fixed some of the problems with incompatible CF cards, either way the card itself may not be liked by your Amiga hence the problem.

My memory is fuzzy but I believe I read about the newer CFD a short while ago so may be worth looking into.

I honestly have no clue how old the CF0 driver is, but it's most certainly from Aminet. Will look into this though. The port itself is ok (no bent pins or such.)
Thanks for the quick replies!

Actually the driver *was* newer than mine but the same *%&#! as before.
A little research showed that the FAT32 support of Fat95 is experimental. Could it be the problem? Perhaps format the CF as FAT16?
By the way, despite the write errors (error 64) the files copy ok. It's tedious to click them away though. And extracting archives fail.
But I can do that via 7zip before putting them on the CF.

What you could do is try another card – but beware that the cheap Sandisk 16 GB cards aren't PCMCIA compatible.
