When I start a program with the little shield on the icon (it's the UAC I guess) it's freezing, and a few minutes after, there is an error "The device is not ready". The problem is only with the UAC, I can run all other programs or games as long as the UAC doesn't ask for permission.

An example with the task manager, when I launch it, whatever how I do, there is the same error C:\Windows\system32\taskmgr.exe "The device is not ready". Same problem if I try to install something on E:\ only the address is changing. I tried to deactivate UAC in the control panel, but I can't because UAC ask for permission xD If I click on "Change User Account Control settings", the window deselect itself, and nothing happen :(

I hope you can help me without reformatting my computer :'( it worked well yesterday.

Thanks for reading.

It may be due to several reasons, either internal or external. The device is not ready is a signal that there appears a problem in connection. This article will explain all other countable factors leading to the virtual disk manager the device is not ready along with quick-fix methods to resolve it.

If considering an external storage device as an example, then a loose connection with your device will not allow it to be detected and you cannot access it. Rather you would get a message that the device is not ready. Other reasons may count for a damaged device (physically or technically corrupted devices), compatibility issues (the devices are not technically compatible to be accessed and perform any task), the hard drive attached is not compatible with the operating system, or due to damaged or corrupted system file. Any of the above problems may lead to a virtual disk manager the device is not ready windows 10 (if you are a windows 10 user). This article would further explain the error and the solutions to fix the error. Here are the topics that would be discussed in detail.

It mainly arises due to faulty connections. Other primary reasons include a damaged digital device, hardware failure, compatibility issues, connection issues, or sometimes Windows file system corruption.
