TeleDisk Import Crash

Post by Martin Hepperle »

Hi Jeff,

I tried to import a TD0 file into the HxCFloppyEmulator and it crashed. I guess that this specific TD0 uses some special format which has not been encountered during testing. If HxCFloppyEmulator cannot read this format, it would be nice if it could detect this problem and offer a error message instead of crashing.

Attached are two TD0 files from the same source which both crash the software.

In looking at the *.TD0 files, it appears they are corrupt, 1 track, on 1 side, and zero bytes.
At least that is how the Imagedisk Utilities see's the file.

Not sure if this was related but i made a fix in the td0 loader in the last release. This should be fixed now.
EDIT : Well, it is not... Fixing the crash.

I'm running Ver v2.4.1.1 and I can load the Hx20boot.td0 Image just fine as a .TD0 or .IMD type file.
40 tracks 2 sides and DD.

HX-20 Info:
40 track double density, 16 sectors of 256 bytes per track/side. The disk geometry is identical to that of the QX-10, so
the first four tracks are reserved for CP/M CCP, BDOS and a large BIOS. Track 4 is the directory and track 39 is not
used. This leaves 278 kByte per disk for use data. A system disk, containing BOOT80.SYS (TF-20 boot file, also
referred to as TFDOS) and DBASIC.SYS (HX-20 Disk basic extension) has about 8 kByte less space.

Jeff,
I built ver r1972 on Debian 9.x 64-Bit, and tried to load hx20.td0. I am getting this error message:
Load error! error -2

It does work correctly for Hx20boot.td0.

Will you double check the functionality of r1972 with hx20.td0?

Thanks.

Larry

What did you expect with a corrupted TD0 ? A crash ? :lol:
