Recently I bought a new external HDD and wanted to move files from an older one. Everything went fine for the most part but at some point they were files which couldn't be moved or even copied.
I thought there was bad clusters even tho I actually can use these files (mp3s for instance) but today I bought a USB SD card adaptator and the same thing happened. I can use the files or copy new files to it but I cannot move or copy from it. Also it seems to shut down when I do that (the light goes off until I plug it back in). The external HDD won't shut down since it's not powered by the computer.
Don't know if it helps but the OS is Win 7 Pro.
Any idea what's going on and how to troubleshoot that ?
