So I installed magic disc not seeing on the internet that people are having problems with it, and now it doesn't work and it's causing crashes. I can't even uninstall it from safe mode, how would I get rid of a program like this?

Lucky you :p
I didn't have a System Restore point available, but I figured out how to uninstall it:

1. Boot into Safe Mode
2. Browse to C:\Windows\System32\Drivers
3. Delete mcdbus.sys (this is the MagicISO SCSI Host Controller which is what's causing all these problems!!)
4. Reboot, and now you can uninstall it

Voila!

Ah, nice. How is it that a normal program like this can end up being so insidious?
 

My Computer

In my estimation, it has to do with how insidious a driver like this can be, by its very nature. Since it's working at such a low level, and it interacts with so many windows services (and Explorer, for one, basically tries to probe it at every chance it gets), this ends up causing red flags to be thrown all over the place and thus the indubitable crashes.

:P

that's my.. uh.. rather untechnical understanding of it.

One question though, how didn't you have a system restore point? I had one that was made during the beginning of the magicdisc installation.

It's kind of a habit, but when I install windows I go and disable system restore altogether. :rolleyes:

Hello beatsme

Never a good idea to disable system restore before you have all your apps installed and stable even then its better to customise the resource use than disable it altogether - It's saved so many people (including me :o )

Why would you disable such a life saving feature? :confused: At least wait until you have everything installed and have it working the way you like it before disabling it, personally I just use disk cleanup about once a week and delete all but the last restore in the more options Tab.

Hi,

Yes MagicDisc works ok. The free version PowerIso does so much more though.

To be honest I used to use Daemon tools lite, and then alot of people said that it was now packed with Ad-ware and what not, So I downloaded magicISO and well what a waste of time, to emulate the drive i needed magic disc which I installed which then just didnt even work or get recognised, my adive avoid this programme like the plague >.>

beatsme,

Thank you. Your advice was a lifesaver. I had no restore point either, and your instructions worked perfectly! Thank you again!

Optional fix.

Additionally you can try this fix if that doesn't work for you. I've had a winxp computer that magic disc has worked fine on, and then one where it didn't. Had issues with 64-bit vista particularly... I switched to Daemon, the only thing is I liked how it didn't have to restart the computer to install. Very nice for school computers when you want to run a disc emulator, but they have Deepfreeze or similar things preventing installation of programs that require a restart.

Anyhow:

1. Open Regedit (windows key + R = runbox, type in regedit.exe)

2. Search for 'mcdbus'. Delete the entire folder (should be like HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\mcdbus)

3. Search again. Delete this one too (should be something like HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\mcdbus). Note you may wish to actually export both of the above first, just in case.

4. Reboot the system.

5. Ignore the error that comes up on startup due to failed driver load. (if it does)

6. Open Task Manager (ctrl+shift+esc), make sure you don't have mcbus.exe running, if it is kill the process.

7. Run the uninstaller again.

8. If that fails as well, try just deleting Magic Disc folder's entire contents, (with it removed with regedit, you should have permission, make sure you are an administrator on the computer.) Also make sure you deleted the driver mcbus.sys (in main sys32 drivers folder, as indicated above).

Why would you disable such a life saving feature?
I disable it on computers with 512mb or less ram, it just takes up too many system resources for such a computer. I back up important files regularly onto a network server, as well as a removable disc drive, so I'm not that worried if I really do have to reformat and reinstall windows. It only takes 30+ minutes tops, especially with the nice batch file I have that installs all the programs and gets all the windows updates I want, without user intervention.

Depends...
its very useful....its simple too..thanks a lot beatsme...:D it worked out for me also....

1) boot into safe mode
2) browse into c:\windows\system32\drivers
3) delete mcdbus..i.e( magic ISO SCSI host control ) this is only causing problems.
4) reboot and uninstall it....:D

hey, you need to re-install magic disc, un-mount all drives and set to 0. download "Revo un-installer" (free) and un-install via this program. awesome program :)

I use UltraISO it is free and works a treat, whats better is you can uninstall it if you don't like or use it anymore and the uninstaler works too !
