Extreme SSD 55AE is hidden and cannot be reformatted - help please!


I bought my sister a 1TB SanDisk Extreme 55AE.

She uses a Windows laptop.

She managed to find the hidden file for her Apple iPhone backup that was taking up approx. 50GB of space on her laptop.

She moved that file over to her SSD to clear space.

It has now hidden the drive…

I can’t see it when it is plugged in, unless I also tick the box to View Hidden Items.

When I try to reformat the drive it says there is no drive there to reformat.

I was just going to try and clear the drive and start again… but I can’t seem to find any way to do that.

Any suggestions? Or do I need to give up…?

Thank you. I am also facing the same issue and want to solve it. I am glad I found your post. I also found my other problem solution over https://studyclerk.com/thesis-writing here because I need custom thesis writing help. I am not so good at writing an essay assignment.

I’ve had the same problem as above. Tried the suggestion of uninstalling of drive from device manager and it did not help. Anyone else have any luck?


Yeah… either the system controller is dead. Another thing is to check your drivers in Device Manager and try updating or install a new driver from Sandisk
