Hi Marlene, Until the experts confirm otherwise, can you try resetting your NVRAM or PRAM. I have had the same problem on my 27” iMac on 2 occasions and did the reset as advised by Daniel and the drives appeared back on the Desktop. Refer to: https://support.apple.com/en-us/HT204063 <https://support.apple.com/en-us/HT204063> Hope this solves your problem, but please let the group know one way or the other as your solution could be different. Best regards and good luck, Philippe C. On 1 Feb 2019, at 4:35 pm, Marlene Oostryck <[email protected] <mailto:[email protected]>> wrote: Hello All, iMac 27”, Hi Sierra 10.13.6 1. Back Up Time Machine - “My Book” - My Book Studio 11 - 4TB - permanently connected Message - 1.91TB of 4TB available Couldn’t complete the backup to “My Book” Last successful backup 10/1/19 (back-up 1/9/11 - 10/1/19) 2. WD Backup Drive 2 Message - 1.34TB of 2Tb available Backups 10/10/18 - 1/11/18 - (planned for monthly backup- away on holidays from 1/11/18 so this HD was disconnected then). No HD icons are showing on Desktop in Finder. All of the above were installed by Daniel Kerr - My Book installed 1/9/11 - Drive 2 installed on 10/10/18 The “My Book” HD unit is continually flashing. Have done a Google search re this problem but not sure how to proceed to get Time Machine showing up on my desktop again and get it functioning as before. Any suggestions would be appreciated.
