Sorry not up to speed on computer jargon, they are all stand alone external drives which i connect via a USB which are causing the problems. Does that help???
I know its not a SATA drive.

try running check disk on drive 4

Is check disc a program on the computer or something that i need to download?
Don't forget that this is happen on 4 of my devices, 2 external hard drives and 2 usb memory sticks.
