Forum, I've upgraded to TI 9.1 workstation build 3832 from an older build. On both of my Dell Latitude D610 and WS470: 1. Boot to Full/Safe verison of bootable CD 2. Backup cannot see my CD/DVD writer, but Recovery can see. 3. Backup can see my USB harddrive. I remember the previous build can see my CD/DVD drive, but against all common sense, I have deleted the install of that build. DOH!!! Any suggestion?
