I'm not sure where this question should be posted. I've got a 3 tb Western Digital My Book Studio external drive that I use for backups. I bought it in July. I've got a 2 tb partition that I use for Time Machine and a 1 tb partition that holds old photos/music files. Last night, I started getting errors on time machine backups. I tried ejecting the disc, and got an error that it could not unmount. I tried disc verify and disc repair, and got similar errors -- that the disc could not unmount. I turned everything off. This morning I plugged it in and ran disc verify -- I got an error code that the disc needs to be repaired. When I ran disc repair got an error code that the disc couldn't be repaired, and, in red, "File System Check Exit Code 8." Any ideas how to fix this? Any ideas what caused this? Is it likely a bad drive, something I did or a software issue? Thanks.
