In my newest PC, Windows 10.
Well, i had been swapping HDD drives between SATA ports, replacing a few with bigger drives, until i was satisfied with the configuration.
Some of the drives -all are brand new WD Golds- became VERY unresponsive, took Windows more than 10 seconds to open any folder on them.

I fixed it.

  • Device Manager
  • Click View. Make sure:
    • "Devices by type", and
    • "Show hidden devices" are selected.
  • Expand IDE ATA/ATAPI controllers.
  • I had two transparent (= hidden) Standard SATA AHCI controllers.
    Their Properties said "Currently, this hardware device is not connected to the computer. (Code 45) "
  • In the list, right-click on each of them ---> Uninstall.
  • In top menu select Action ---> Scan for hardware changes.
    Let it take its time.
  • Reboot the PC.

Problem solved. All drives super responsive. No hidden controllers anymore.
