Hi
Thank you all for replying, strange about the SanDisk drives I bought the Sandisk ultra flair 64GB 2 weeks ago I tried to update my firmware for 3 day's using this stick it would not read it? I checked the forum and loads of users were having the same problem not with SanDisk but all sorts of sticks.
Hi Mike,
SanDisk USB drives usually come with their encryption software (Sandisk Secure Access) installed.
This type of software can cause problems with some systems, even if you haven't used it, and this may be why your keyboard couldn't access the firmware update file.
It sounds as if you have now managed to return the SanDisk device, but if you had formatted it on the keyboard, then that would not only have ensured that the device was formatted in the FAT32 format required by Yamaha keyboards (although I suspect that it was already FAT32), but should have deleted the security software from the device which was probably causing your problem.
SanDisk are not the only manufacturer to include such software on their products, so I would suggest checking the next USB that you buy as soon as you get it, and either delete any software if found, or simply reformat it (as FAT32), preferably on the keyboard, which will effectively delete it for you.
Regards
Ian
