vusun123 Posted April 15, 2016 Share Posted April 15, 2016 external WD 1TB HDD random disappear several times always on boot to desktop.Seems like USB flash Drive can also disappear. Open DIsk Utility, right click it. If it said "Show in Finder" then it probably be an Apple thing Link to comment Share on other sites More sharing options...

If it said "Show in Finder" then it probably be an Apple thing Thank you for your reply,I follow your step and it should be an Apple thing. I right now use Disk Utility to rescue the WD HDD,and it say Updating boot support partitions for the volumes as required.but no help. 10.11.5 toleda is the only thing that realtek alc885 audio work perfect on my computer.seems like c-media usb audio card is bad because it cause my external HDD disappear. create new OS X user,reboot 10 times,seems problem not solved,turn off EIST,seems problem solved.I will keep report. seems like the problem cause by hdd fan disappear.I install debian fail before remove hdd.
