I'd been using Tuxera FOREVER
I'd been using Tuxera FOREVER. However, I found that many of my external hard drives that had once been READ/WRITE had arbitrarily reverted to READ-ONLY. Tuxera doesn't have a convenient way to change from READ-only to READ/WRITE. This has been a MAJOR issue for my drives. iBoy easily corrects this issue, allowing me to avoid reformatting drives that had previously been just fine.
