USB Drive Folder Shares Are Not Accessible
You connect a USB external hard drive to your Windows computer. You create a folder on the drive and share it. You then browse to computersharename but the share will not open. Shares created on internal drives work fine.
Solving this problem requires a Registry edit:
Click Start, and then click Run.
Type regedit, and then click OK.
Navigate to the following registry key:
In the right pane, double-click the IRPStackSize value.
Important: If the IRPStackSize value does not already exist, you will need to create it:
– In the Parameters folder of the registry, right-click the right pane.
– Point to New, and then click DWord Value.
– Type IRPStackSize.
Important: Type “IRPStackSize” exactly as it is displayed because the value name is case-sensitive.
Change the Base to decimal.
In the Value Data box, type a value that is larger than the value that is listed.
If you created the IRPStackSize value using the procedure described in step 4, the default value is 15. It is recommended that you increase the value by 3. Therefore, if the previous value was 11, type 14, and then click OK.
Close the Registry Editor.
Restart the computer.
