Have you inserted a Memory Card or USB and it's not showing up in your list of devices?
There are a few things that can cause a Memory Card or USB not to show up on your Windows or on Finder (Mac) when inserted.
- 1The USB device or Memory Card is defective.Advertisement
- 2Another reason might be that the computer itself has some sort of hardware failure.Advertisement
- If the USB has worked on the computer before, and works on other computers with no issues, then check another USB slot located in another location on the computer.
- 3Sometimes, the firmware that comes with the USB reader will not recognize certain devices such as SD card readers, while the slots on the front may have different firmware specifications.
- If the drive still does not mount from anywhere on the computer, check to make sure another - similar device will work in a chosen slot.
- If other USB devices work in the same slot as the one in which USB drive will not mount, then the USB should be checked on another computer to see if it will mount on those.
- If the USB drive will not mount on another computer, it will be highly unlikely you'll retrieve any data from it.
- 4Before replacing the USB drive, it may be worth checking to see whether it is a defect, or something which can be fixed in the Windows system.
- 5If the drive worked on a computer before, Windows should recognize the device and communicate with it.
- This reference in the Windows database may be out of sync with the current state of the device.
- To create a fresh start between the computer and the USB drive, the drive's reference will need to be uninstalled in the database.
Windows uses the Device Manager to list and manage hardware connected to the computer.
- 1Plug in the USB and open Device Manager.
- With Windows 7 and below, the Device Manager is in the Control Panel > Hardware and Sound > Hardware and Printers > Device Manager.
- In Windows 8, right click the bottom left corner of the screen and select Device Manager.
- 2In Device Manager, select View and make sure Show hidden devices is selected and close the Device Manager.
- 3To make sure all of the possible installed devices are listed in Device Manager, enter these commands:Then open the command prompt.
set devmgr_show_nonpresent_devices=1 start devmgmt.msc
- 4This will allow "ghost" devices that don't show up even as hidden devices to be seen in Device Manager and will also open Device Manager.
- 5If there is a known error with the device, there will be a yellow triangle on the icon. Right-clicking and selecting "Properties" will open the interface to view information about the device and manage its references. If the driver cannot be updated, the device will need to be uninstalled.Your device should now be found in the device list.
- From the Device Manager, right-click on the troubled device and select Uninstall while the device is plugged in.
- Unplug the device and reinsert it. Windows should automatically install a new reference.
- 6If the device will not work no matter what you do, and this method yields no success, the device my be defective and will need to be replaced.Advertisement
