VirtualBox Won't Attach USB Drive - Access Error
Did you have a usb drive that was attached and working perfectly then all of a sudden it wasn't?
We did, and after fixing it the long and wrong way, we found the way it should be fixed and it's a quick fix!
Here are some other things you can try that we have also used to fix this issue when the above issue did not solve it:
* Try This Second: IF the above video does not work - turn off write protect on your USB drives via the registry
Apply the following regedit file and reboot
Run this regedit file which you can download here.
* https://cloud.compumatter.biz/s/BSZmM...
Reboot your system
* Try This Third: IF neither of the above attempts worked.
Check to see if Windows has renamed your drive so VirtualBox can't find it.
This was a big surprise. I had knocked the USB loose and in the process of reattaching it was given a new Name by Windows ie; PHYSICALDRIVE4 was renamed to PHYSICALDRIVE3.
Take a look inside your passthrough vmdk file. In Windows, this command will tell you where any of your vmdk's live and be sure to include both all four quotes: "C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" list hdds | findstr /c:"pass"
Now you can edit the contents of your vmdk with notepad and see what it PHYSICALDRIVE it is pointing to for instance this is one example from my vmdk file:
Extent description
RW 5860533168 FLAT "\\.\PHYSICALDRIVE3" 0
Now let's get a list of the drives on your actual computer. From a command prompt type:
* wmic diskdrive get model,name
You will get a list of drives like this:
Model Name
RSH-339 ASM1153e SCSI Disk Device \\.\PHYSICALDRIVE3
Samsung SSD 860 QVO 2TB \\.\PHYSICALDRIVE2
TEAM TM8FP4004T \\.\PHYSICALDRIVE1
TEAM TM8FP4004T \\.\PHYSICALDRIVE0
See if your drive has been renamed. If it has, close VirtualBox, edit your vmdk file and put the new correct name in your vmdk file. Then restart VirtualBox
In some cases you may have to detach and delete the attachment and reattach your drive to the new drive name. However it worked fine after that. No problems.
I hope one of these help. Remember, I take zero responsibility for you to carry out these tasks on your computer. They worked for me in all cases. That's all I can assure you of.
