This means that Windows may assign the DataTraveler a drive letter that's already in use by a network share or Universal Naming Convention (UNC) path, causing a drive letter conflict. This does NOT pertain to network shares because they are specific to user profiles and not the system hardware profile itself, and thus appear available to the OS. This DataTraveler requires two consecutive drive letters AFTER the last physical disk that appears before the 'gap' in drive letter assignments (see figure below). You will need to run the uninstall as the Admin to be able to perform this while logged-in as a non-Admin.Īlso check the setting for your security programs (Norton, Symantec, etc). You may want to try this even if you do not see any yellow exclamation marks for this device. Uninstalling the device with the exclamation mark and scanning for new hardware sometimes will work as well.

You can also look at Device Manager when the Data Traveler is connected to see if the drive comes up with any yellow exclamation marks.

Remove all entries except for default (it won't let you anyway). In the directory list on the left side, find the entry HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. Here are instructions for backing up your registry. Make sure to back up your registry before making any changes. To do this, go to start and type regedit in the search field. When all the entries cleared the drive should work again. Restrict CD-ROM access to locally logged-on user only is set to disabled.Īlso, too many entries for mounted devices in older computers can cause this problem. Run gpedit.msc and go to Windows Settings>Security Settings>Local Policies>Security Options and make sure Devices: We've seen this happen when security software blocks the user's ability to write to CDs/DVDs.
