PFS3 SD card Setup

[LuigiThirty]

I have an A2000 with a GVP 030 SCSI host, a SCSI2SD and 4GB SD card and I'm trying to get PFS set up. I have two 1.8GB partitions on it. I connected the SD card to my PC and loaded it with WinUAE, partitioned it with the PFS3 filesystem, and formatted the partitions I made with pfsformat, following the instructions here. I installed Workbench on it and I can boot my Amiga with the SD card.

The problem comes when I try to do anything on the drive though. If I try extracting an .lha file, I get PFS-III error requesters that say Write Error 0 counting up every 64 sectors/32KB. Tiny files (like saving a new script with ed) work fine. After the write errors I get block ID errors on that volume when I try opening any directories until I reboot. pfsdoctor can't find anything wrong with the volume. What am I doing wrong here?

MaxTransfer is 0x1FE00 like in the PFS3 walkthrough there. Can I lower it without having to reformat?

HDToolbox said I'd lose all my data if I changed it was why I asked. The settings should all be the same as on the page but I'll double check when I get home.

I'm using PFS3-AIO 2.3, the one on AmiNet. The SD card is a standard 4GB Sandisk that's brand new.

It's also got a SCSI CD-RW drive and a fried floppy drive if that matters. (I have a Gotek in my ST that I'll probably throw in there.)

My startup-sequence adds 200 buffers to DH0: and DH1:. I've got 12MB of 32-bit RAM and 6MB of fast RAM.

Here's my file system from the HDToolbox setup. (I tried lowering Maxtransfer to 0xFE00 but it didn't help other than lowering how much was transferred between errors...)

It looks like that fixed it! I guess my hardware doesn't like PDS\03. I also changed it to add the buffers through HDToolbox. Thanks!

Now if I could get a fancy desktop on my machine like yours there I'd be set.
