Possible FindFirst/Int24 bug

[shidel]

Not completely sure this is a bug, or just odd compatibility behavior.

VM consisting of 1 virtual HDD.
No LFN support TSR running.
Program Traps Int 24 to prevent OS from throwing up error messages.

Performing FindFirst to drive D:, int24 invoked, FindFirst reports error (i think path not found).
Performing FindFirst on unpartitioned C:, int24 invoked, FindFirst reports error (same).
Performing FindFirst on partitioned, but unformatted C:, int24 invoked, FindFirst reports no error, (only no more matching files).
Performing FindFirst on partitioned and formatted C:, int24 not invoked and all works as it should.

To me, it seems like it should report an error when doing a FindFirst on an unformatted C: drive. But, IDK if its a compatibility thing or not. Haven't tested this on other DOSes. Obviously, it is not difficult to work around. Just wanted to point it out.
