My PsR 3000 doesn’t read the type of files in my USB, it shows signs of power and connection when I plug it in but somehow it won’t open any files stating data downloading wasnt complete or something.my USB works fine on my psrs970. Help
I would try the troublesome USB stick in a computer (any OS) and see if the files can be seen/accessed there. There are many OS specific tutorials on line for correcting filesystem damage to these typically FAT formatted devices. Modern linux systems will give you more powerful options for backing up what is currently on the device to another device or to a hard drive before subjecting the device to any recovery attempts.
