Microsoft Drops 'Safe Removal' of USB Drives As Default In Windows 10 1809 (betanews.com)
Mark Wilson writes: Since the arrival of USB drives, we have been warned that they need to be 'safely removed' using the correct method in Windows, rather than just being yanked out — but now this changes.
With Windows 10 1809, Microsoft is changing the default setting that's applied to USB drives and other removable media. The change means that the default policy applied to removable storage devices is Quick Removal rather than Better Performance — so you can now just pull it out without a second thought.

"Quick removal" means the OS will sync all data to disk BEFORE telling you the copy is complete. So if you wait until the OS says the data has been copied, you will be fine.
This is how floppy disks used to work. As soon as the copy completed the light would go out and you could eject the disk. It really should have been that way by default from the start with thumbdrives.
EVERY SINGLE WINDOWS since XP defaults to "Quick Removal" for ALL removable drives, including every iteration of Windows 10. I have yet to see a single computer running XP, Vista, 7, 8, 8.1, or any build of 10 where I plug in an SD card, USB flash drive, or USB hard drive that did NOT automatically default to "Quick Removal." I have ALWAYS, as in 100% of cases, had to manually switch the performance setting through Device Manager. Anyone who says that the default policy is different is flying directly in the face of every single computer I've ever plugged a USB or memory card storage medium into over the past 17-18 years, and that's literally thousands of machines.
The only exception is when a drive is not the system drive but is connected to an internal potentially hot-swappable interface such as an AHCI SATA port. Those get set to "Better Performance" by default because they're almost always not in a removable tray nor connected by eSATA, even though they're technically hot-swappable. Of course, that's not what this Slashdot post is talking about at all, so again...WHAT IS THIS POST EVEN TALKING ABOUT?!
It's not really practical today.
AmigaOS could do that with floppies because back then the computer was 100% in charge of the drive and knew exactly what had gone through and what not.
A modern disk runs an entire OS of its own, and very possibly lies to the OS about its internal state, because lies look better on benchmarks. Just because the drive says "this has been saved", doesn't necessarily it has been.
That means the OS can't really do what you want reliably. It might work with some drives, and fail miserably with others.
If every hard disk was truthful about what's on the platter, and every SSD had the capacitors needed to finish work, this would work nicely. But we unfortunately don't have that.
