Hi BeeJay
Regarding MBAM removal:
Download Revo-Uninstaller from here - click here
You want the FREE DOWNLOAD version not the Portable.
Install and run it.
You should see MBAM listed. Click on this to highlight > then click on "Uninstall" on the toolbar at the top.
It may take a few minutes for any action to take place.
It will give you the option to scan for left over files and registry entries.
If you are unsure about any of this then simply leave this option alone. [ or ask :) ]
==================
Does your external drive show up in Disk Management ?
Click on Search [ bottom left of screen ] type in - diskmgmt.msc - hit ENTER
You should see your main drive and any partitions also your DVD drive PLUS the external drive.
I am wondering if the external drive is formatted ??
Does it show as a Disk number ?
Disk 0 will be your main drive [ and any partitions - C: and E: on my image ]
Your DVD Drive is usually D:
My external Flash Drive is showing as Disk 1 - It is formatted [ Fat32 ] and is showing "Healthy"
Yours, if formatted, may say "NTFS"
We need to know :
1 - is it showing in Disk Management
2. - Does it have a Drive Letter [ F: for instance ]
3. - Is it formatted or does it say something like "Raw"
My DVD Drive was shown below the External Drive [Disk 1 ] in my image but was cropped off
