And, indeed, it won't be free.
My 2 TB My Book Live has an ethernet connection, not a USB and is connected directly to my wireless router. BIG MISTAKE !! I tried to use my Mirror Image program to keep a copy of all my files . . . I write to an external drive from my laptop. Only operating system and program files are kept on my laptop. Of course WD doesn't allow third party software compatibility with it's "wireless" units. So I did two things: A backup through Windows to the My Book and a complete copy and paste of all my data files. Then I deleted them all because it took so long to copy and paste and the backup wasn't accurate, so I decided to sell it.
Then disaster, I dropped my external drive and damaged the heads . . . 20 years of data and no backup !!! I can recover the data from the external drive . . . at a huge cost or, I could try to recover them from the My Book, if I only knew how . . .
