On any UNIX system disk reads are cached and writes are delayed to avoid redundant or unnecessary write operations. This is normal behavior. Unmounting a drive flushes all the caches to the device so it's consistent.
If you remove a drive -- of any kind -- from a UNIX system (including Mac OS X) without first unmounting may or may not leave the filesystem in a damaged state. No, there is no intentional "break me" mode for SD cards. :) On Sat, Jun 4, 2016 at 2:13 PM, Larry Colen <l...@red4est.com> wrote: > I have lightroom set up to eject my SD card after it has read all the images > off of it.
