MacOS 10.15.4 automatic eject sdcard when goes to sleep I bought a transcent jet lite sd card for my macbook pro mid 2014. On MacOS 10.15.4 whenever my macbook goes to sleep my sd card automatically ejected and there is no device in disk utility to mount again and I had to physically put sd card again and it's annoying.

I tried these but none of them solve my problem.


Reset SMC
uncheck put hard drives sleep in energy saver
Install Mountain App
Installing jetdrive toolbox and turn it on
Finally I found what my problem it is I open console.app and filter with /dev/disk2 and found out transcend helper eject my disk so I uninstall app and delete helper tools and then reboot.

Command to delete transcend helper tools:

sudo rm /Library/LaunchDaemons/com.transcend.TSSleepHandlerHelp.plist
sudo rm /Library/PrivilegedHelperTools/com.transcend.TSSleepHandlerHelp
