I'm having an issue and I'm curious if anyone else has run acrros the same thing. I have an older Iomega hard drive, external USB 3.0, 1TB. I've been using it with Windows computers for a long time but suddenly all of my Windows computers no longer want to read the drive. They will see it initially when I plug it into the USB port, but when I start reading files from it or writing files to it, after a few minutes Windows gives up and the drive disappears. This happens on four different computers running Windows 10. However, and this is the weird part, the drive works perfectly on an iMac running the latest OSX. I don't understand why OSX has no trouble with the drive while Windows hangs on it every time. Any suggestions? At this point I've given up using the drive on any Windows system, but I'd still love to know what is causing the problem. In order to use the drive on the iMac I reformat it to Mac format, of course, and when using it on the Windows systems it is formatted as NTFS. I've tried formatting it as exFat and Windows still has problems with it.
