sandisk cruzer 32G  

My testing of Windows 10 shows that the Sandisk Cruzer has no driver
in Windows 10 for it.
I have no idea how to send feedback to Microsoft so this can be added.

It should not need a special driver. Mine work fine but I don't use any software that might come with a flash drive.

mine, ok as well

It's possible that the sandisk is failing but I am able to use it in Windows 7.
Windows 10 says that there is an error with it.
Sandisk not that old and not used very much.
Thanks for responding.

If I click properties for the Sandisk it shows 16,384 bytes being used by
a program called "ReadyBootDriver". If I format the Sandisk it still appears
on the drive. If I do a search on the drive another program shows up
"readyboostperf counters". This search was done on Windows 7 pro 64-bit.
I am also going to try the same thing on Windows 10 when I get the chance.....

I would say the ReadyBootDriver was involved in the situation with Windows 10, but I am not familiar with it. Maybe there is some update for that utility, but I run mine without any such software.

If you decide you want to clean the drive, Diskpart in an Administrative Command Prompt will do that. You could format if as Fat32 or NTFS depending on how you want to use the drive.

The link below shows model compatibility with Windows 8.1, so you might check it. I would not expect to see the same charts for Windows 10 for some time.

I did not put "readybootdriver " on my puter. I want nothing to do with it.
In Windows 10 it just gobbled up 4G of the Sandisk. I have been able to clean the drive
with Format. The default for the driver is Fat32. When I do a search in Windows 10
it can find no traces of it. I can't (don't know how) to point the search in Windows 10
to the Sandisk. Nothing is ever easy
