Windows cannot use this hardware device because it has been prepared for "safe removal"

This error can arise when you try to safely remove a memory chip from an internal reader by right clicking the drive and selecting "Safely Remove".

Resolve the error by rebooting the machine, the reader should be reset at startup.

Now follow these steps:

  • Go into Computer Management,
  • Expand Storage, select Disk Management,
  • In the lower center pane, right-click and select Properties to view the property sheet for the card reader's drive letter,
  • Click the Policies tab and ensure that Optimize for quick removal is selected.

This disables write caching for the card slot, ensuring that no cached information can be lost when you remove the card.
