I can load pictures from my camera onto my A1103 Apple, but I can not load them onto a USB Device, A sheet pops un stating, “There is no available room to Duplicate” I have checked the hard drive and only 15 GB has been used, The total size of the pictures file is 516GB, so I think that there should be adequate room. I thought that it could be the fault of an interrupted Hard Drive
Go under the Apple in the upper left hand corner to “about this Mac”. Tell us what is says about your hard drive. size, available, space, used space Then tell us what the USB device shows about space.
@ac2sde this “can load pictures from my camera onto my A1103 Apple, but I can not load them onto a USB Device” sounds like an issue with the USB device and not the HDD. Try a different USB device.
This is likely a hard drive issue if there is adequate storage available. Try a new Hard Drive.
