If I'm going to have to back up that entire drive somewhere else, I might as well just have to purchase another one and have 2 of them, one for the Mac and one for the Windows machine. I don't really feel like reformatting it, that would completely defeat the purpose to me. I cannot access the files on the drive, and if I attempt to update the driver, it tells me Windows has already allocated the best driver for the device. It gave me the exact same issue on all 3 of the Windows machines, it will not recognize the device AT all, I can see it in there, when I look in Disk Management, but there is not any letter assigned to it, and if I attempt to right click and format or do anything to the device, everything is greyed out. I used it on the Mac first, but it's maybe 2 months old now and has less than 10% used. I've tried 3 separate Windows machines now, a brand new Lenovo, an older Sony Vaio, and a year old Dell, and this driver absolutely refuses to install on ANY of those Windows machines (2 Windows 7, and 1 Windows 10).

I purchased the 1 TB Backup Plus Portable Slim External Drive.
