I have a 3 month old Sandisk Extreme USB3 flash drive (64Gb) which until now has been working perfectly.
If I plug it in now to a USB3 or USB2 drive, I get an error message that the usb device is not recognised and that it has malfunctioned.
With regards to plugging it into a USB2 port, that is as far as I get as the drive doesn’t appear in Windows Explorer.
If I plug it into a USB3 port, I get the error message but about a second later the drive appears in Windows Explorer and I can access the files as per usual.
I have tried this on 3 computers and the same thing happens.
I have searched the forum to see if anyone else has had this problem but couldn’t find anyone (err I’m not very good at searches though).
