Change drive letter designation on internal SD card reader. RRS feed

  • Question

  • I have a Dell with a micro card reader built in. It can read four different types of cards and they are labeled H:\, I:\, J:\, and K:\. If I put a card into the reader, that specific drive (i.e. K:\) shows up in Disk Manager and I can change the letter designation. The problem that I'm having is the other three slots won't show up in Disk Manager unless I insert a card. I don't have the other types of cards and don't want to buy them. Is there a way to change the drive letter designation of the card readers without having a card inserted in them? Thanks,

  • I found the solution: Locate the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices Right-click "\DosDevices\D:", and then click Rename Rename it to \DosDevices\S: - or whatever letter you want.

  • Hi,

    You have known the solution. We can change the driver letter via Disk Management. It cannot be done if it does not show up in Disk Management.

  • I've done the change in the registry on windows 8.1.  Keeping my fingers crossed.

    A follow up question:Does this process require a restart.

    Small rant: I dont know why windows doesnt reserve another naming scheme for these type of card readers that take up a lot of drive letters and cant be changed in drive management.  Z1, Z2, Z3 or something.

  • Thank you. This worked for me on Windows 10, but requires a reboot after changing the registry key.
