I almost always run sync after unmount on USB sticks or SD cards. Old habits and superstitions, I guess.
Recently I saw a USB stick's activity LED stay on long after unmount. I'm not sure if it was writing or something else.
- kzrdude 3y agoTriple sync is at the end of my backup-to-usb disk script
- lelanthran 3y agoPossible. The little microcontroller that does the actual write to pages of flash might actually be busy moving things around and doing other housekeeping after the disk is unmounted but while it still has power. I wrote the firmware for a flash based system, and used powered-yet-unmounted time to save a few statis to the uC's internal flash.
- bayindirh 3y agoI have seen that too. It generally means the drive is doing write leveling and/or other tasks. If I have time, I wait for that, too. However, LEDs become rarer and rarer these days.
