[Bug 44706] New: disk access terminated (C and Z) - Unreadable / Unwritable

Bug ID: 44706
           Summary: disk access terminated (C and Z) - Unreadable /
                    Unwritable
           Product: Wine
           Version: 2.0.2
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

I have been trying to run a Game Server from 1996 in Wine (runs fine on my PC).

After a random amount of time (5 - 45 minutes) the program will state:

Cannot write to drive Z:\
Cannot write to drive C:\

It will spam this if I try to save anything. But it will successfully load when
the program loads, but after this happens, the drives disappear from the
application's reach.

To put this into better perspective, imagine you are running Windows and
suddenly your C Drive disappears, but Windows for some reason is still running,
but nothing you do in Windows is being saved. You can't open any files because
your drives do not exist.

I've tried this in NON-ROOT and ROOT, both are the same issue.

I am now looking into using SMB or Network drives because Networking doesn't
seem to be broken.

I also tried debugging to figure out the issue, but WineDebug gives me machine
code, nothing useful I could understand (like a 10 million line list of "Can't
access drive C:" anywhere.

Hoping someone knows what's up. I am using the Stable version for Ubuntu 17.04.

Thanks,
Nathan

Just so you guys know, I understand that Wine exposes my entire root system
with .wine/dosdrives/z

This becomes inaccessible - just in case someone points out a very simple
mistake most people might not understand unless they read some of the docs /
setup information / man pages.

Spent around 8 hours on this issue so far.

I may be able to reproduce it by attempting to read a disk file rapidly until
it breaks the file system - Question is, why would the filesystem break? Is it
some kind of service running?  Why isn't it solid and persistent like hardware.

Hoping for help - thanks

What is the name of the application?  Is there a download available?

Jeff,

Actually it looks like it has to do with the fact that I am using an "fopen"
command every second to check for commands I place into a commands.txt file.
After I disabled all of this code, the program ran for 8 hours straight.

To answer your question, it's a bit complicated because it's a game server.

As soon as I get some time I will make a program that will attempt to reproduce
this so it can be run in Wine and then debugged to figure out what's going on.

It's a C program called Blakserv (Meridian 59 Game Server).

I will get back to you with an example that can reproduce the issue so it can
be debugged.

Thanks for getting back to me so quickly!
