problems with SDX with sio2usb and APE


Recommended Posts

Hi, I encounter strange behaviour of my BGPconverter writing to a pc folder with Ape and sio2usb cable. No problem with DOS2.5 but with SDX the atari locks up after a few sector writes. I cannot reproduce this in an emulator so I'm at a loss what is happening. Going to insert some screen color markings at strategic places in my code to find out where it hangs up.

 

Is there anything that might be special or different when it comes to SDX compared to DOS2.5??

That's right: it doesn't work. SIO2PC with RespeQt allows the use of the SDX PCLink driver, which allows read/write access to mounted folders on the PC and is generally a much better solution for SDX.

 

Not absolutely sure (perhaps Konrad can correct me if necessary), but I believe APE relies on sectors being written in a specific order. The SDX DOS 2.x driver may not write out sectors in the expected order.

I just tried with 2 real 1050 floppies in enhanced density - SDX messes up a freshly dos2.5 formatted disk after saving 2 files and deleting one.

The remaining file is corrupt - error 164 when loading.

 

Is this also a known issue with SDX and real floppies?

Ehm, no, it's more an issue of having overlooked that when reading the manual ;).

 

-> page 166 or 8.6.1.2
