DiraskDsk: Multiple files are rewritten again, while only saving another file

[fboelens]

When saving files (like in trilotracker or graphsaurus) with drive b as 'diraskdsk', I can see a lot of 'untouched' files, are being saved again..

Config: MSX2, PHILIPS NMS8255, OpenMSX on Windows

BTW: It also seems trilotracker tracks are being corrupted, but I'm not sure if that is related.

I can reproduce this (in Linux). Here's a simpler scenario:

• Start openMSX, insert an empty directory as dir-as-disk.
• In BASIC, save an empty program: SAVE"TEST1.BAS"
• A few moments later, save another program: SAVE"TEST2.BAS"
• Check the host files-system: BOTH files now have a modification timestamp of the last save!
