USB thumbdrive in FESEM Published September 23, 2019 By Status There have been a few problems getting thumbdrives to eject on the FESEM PC. What I did that worked is to make sure that Explorer is not pointing to your data on the FESEM PC, then highlight your USB drive in the list, right click and select Eject. ← Previous Post ESEM monitor Next Post → S-TEM rate change
