"IOException: The device is not ready" when loading `.cue`

Summary

When I try to an error message box appears instead of booting the game.

Repro

Just click File => Open ROM... or simpy press Ctrl+O and then open "Sonic 3D Blast.cue" and then this error message box appears on screen.

Output

A core accepted the rom, but threw an exception while loading it:
System.IO.IOException: The device is not ready.

The nature of the error would imply this is not at all related to the actual game per se, as it ends up erroring in internal OS code when trying to resolve the .cue files. Could you post the exact .cue file? Also, where exactly did you place this .cue file?

I placed the .cue file in a directory where I place all the games that I want to play in the future and the content of the .cue file is:

in a directory where I place all the games that I want to play

Is that directory F:\SEGA SATURN\101-150? Probably not. The .cue references an absolute location that doesn't exist.

[CasualPokePlayer]

Remove the F:\SEGA SATURN\101-150\ and make sure the 125 SONIC 3D BLAST (U).BIN file is next to the .cue file.

Why BizHawk doesn't show me a clear error message box?

[nattthebear]

It does. Drive F: is not ready, and you'd get the same if you tried to access it in Windows Explorer.

[CasualPokePlayer]

BizHawk is not a human, it doesn't understand that you're "asking" to access drive F because you got your dump from some shady site and didn't put it in there yourself (if you otherwise dumped it yourself like you are "supposed" to this would not be an issue, even then how people find these weird fubared dumps is beyond me) and doesn't understand the exact solution.

(EDIT: ignore issue reopen, finger misclicked)

[YoshiRulz]

I agree that "The device is not ready" is not a helpful message for the end-user. We should encapsulate directory enumeration and throw "file not found" in that case. (And then handle missing files in .cue parsing better.)
