| I don't know if this is the right subforum for this, so don't delete it, just move it to the right one, please. I noticed a very strange issue with a V500V2+ and the trackdisk device. Well, first the setup: Amiga 500+ with an additional 1 MiB card, a Chinon FB-357A HD drive and the Vampire. Amiga OS3.1 with MUI, MWB and PFS3 (the aio handler version) and nothing else. The issue: Everytime I try to write back an ADF file to the internal drive, to an external DD drive or to RAD I get NDOS disks most of the time or sometimes disks with some heavy checksum errors. It doesn't matter if I use adf2disk, adf-blitzer or the fine tracksaver. If I write the ADF files to the disk with another Amiga (also a FB-357A) I get perfectly working disks. If switch the Vampire for a Viper 520 I also can produce perfectly working disks with the Amiga 500. Even using the format command sometimes produces non-working disks. It doesn't matter if I turn caches off or booting without startup-sequence. I also checked this with GOLD2 and GOLD2.5, same result. So are there any known issues with the Vmapire 500 and the trackdisk.device?

| AFAIK this works flawless with GOLD 2.7

| Can someone reproduce this? It drives me crazy. How do you get beta access?

Have to be on the development team, or be a lucky youtube reviewer with connections with the development team. Or just wait a little longer until it's released.

| Sorry, I couldn't reproduce this issue with the Gold V2.5 core. A couple of things that come to mind are that is your PSU strong enough and have you set your MaxTransfer to 0x1FE00. Did you copy your source ADF-file back to the another system and made a CRC check for it that it is not corrupted? (your RAD-drive problem indicates it) ![](http://apollo-accelerators.com/files/shk/trackdisktest.png)
Tested with V500V2+ / Chinon FB-357A HD drive / Amiga OS3.1

Thank you for looking into this. I've a selfmade powersupply delivering about 80w, this one works perfectly. I also use the proper 0x1FE00 MaxTransfer value. I actually had to go for a 0xFFFFFFFC mask and a 0xFE00 MaxTransfer (you know < 64KiB). That worked in the end. Maybe the flash memory is a bit weird.

Sounds like a head alignment issue to me.

What the ... did you even read my post? How does a swap of the accelerator make a head alignment issue go away? Furthermore, can you explain me how a head alignment issue of a RAD drive looks like? *facepalm* Did you notice that I already wrote how I got rid of the issue?
