Yesterday I was able to successfully install RB on iPod Classic 6th Gen, using emCORE, but got CRC errors while loading the 80GB HD with music. Windows 7 wanted to reformat the HD, but I ran cmd>chkdsk /f /r, & got an error msg, & it failed to complete chkdsk. Today RB is hung all morning in "scanning disk." I can't map the drive to reformat it in Win Explorer. Suggestions to get the drive mapped, to reformat it?
