All Disks Vanished...Apple Support stumped


hi

thought put out here, although mac running hit odd glitch few hours ago.

mbpr late 2013 - 128gb ssd

when got home , woke mac sleep whole window had frozen, had no option power off. upon restart folder question mark flashed , go no further.

did following:

  1. booted holding option key - went straight internet recovery
  2. in recovery tried disk utility - no hdd found recovery osx base 1.2gb partition
  3. in recovery tried time machine restore, found network disk not restore not see hard drive on mac
  4. in recovery tried fresh install - again not find drive install to.
so while hanging on phone apple support tried booting safe mode , mac booted fine, working. explained on phone , lady stumped, verified colleague , agreed needed come in couldnt understand how possible.

anyways whilst on phone went recovery , again disks not visible @ all. booted safe mode , fine.

anyways think ssd knackered (unlikelyimho). after booked appointment wdecided uninstall last thin instaled morning synology assistant (for locating nas on network) , rebooted. rebooted normal mode ok time. thought try , select startup disk on reboot, , bam no disks again.

after reboot got question mark again after few minutes went through. if reboot sees startup disks ok again , reboots every time.

stumped not word!:)
 

based on above, synology assistant appears culprit. i'd uninstall software , contact them.
