I can't think of any case where you would want C: to be reported as a non-fixed drive - I suspect Windows may behave this way even if it was installed to a removable disk - and as far as wine users
are concerned, the C: drive should be a fixed drive.
More importantly my patch should not introduce any secondary bugs, and that was my top priority.
You say it reports DRIVE_UNKNOWN, but create_drive_devices uses this logic:
drive_type = i < 2 ? DEVICE_FLOPPY : DEVICE_HARDDISK_VOL;
To me it was pretty clear that all drives without a registry value are going to show up as DEVICE_HARDDISK_VOL, which translates to DRIVE_FIXED, which means that the "auto-detect" type is not being
used on drives without an override value (and winecfg stores no registry value for drives set to auto-detect, so it can only be set with regedit).
I was afraid of changing that logic due to the probability of introducing new bugs, and thought that someone who knows that code should tackle that when they have time.
