Hi, thank your for the prompt reply.
I tried to right click the 'Mass Storage Controller' and choose 'Update driver software', but after loading for a while, the pop-up screen said 'unable to find the driver software' and ask me to 'find the manufacturer of the device'.
I have no idea how to find it by myself. what website do you suggest to get the best driver?
I am not sure if it is an external drive, but it is very likely. I tried to uninstall some programme on my laptop last week, and I think I probably deleted some programme that I shouldn't. I can't remeber what it is. Is there any way I can find out what I have mistakenly uninstalled?
The reason I ask for soluation for this problem is that, I think, it affects the performance of my laptop. I have been having trouble recently to switch on my computer, the system seems not to respond. I have to force to switch off the computer and turn it back on again by choosing the SAFE MODEL. I then run a system restoration under the SAFE MODE, only by doing that, I can get back to the normal window and use it.
Do you guys think it is anything to do with this Mass Storage Controller? can I just disable it and ignore it, or I need it to be fixed to run my PC properly. ?
