Safely Remove Hardware Icon is Missing Q: I have my USB flash drive plugged in to my Windows XP system. Normally, when I go to unplug this device, I click on the little icon located in my notification area (lower right corner). However, I have just noticed that the icon is missing and am now afraid to unplug my device. I have been told that you could lose the data on that drive by just unplugging it.

5. USB device does not appear in "Safely Remove Hardware" Q: When I click the "Safely Remove Hardware icon in the notification area, the device I am trying to remove does not appear. I'm running Vista Ultimate. Is there anything that I can do to solve this? A: According to Microsoft the problem occurs when either of the two scenarios apply: The USB device contains an embedded USB hub. The embedded USB hub detects a device that is connected to the USB hub as being a non-removable device. The work-a-round for this issue is to shut your system down before you remove the USB device.

A: The older version v1.1 USB port will not run a newer version v2.0 USB device. However, a v1.1 USB device will work in a v2.0 USB port. I would suspect that your Windows 98 machine has the older version port installed. Note: Windows XP requires SP1 for v1.1 to work. Also, be sure to update the driver for the USB controller in Device Manager once SP1 is installed. 7. How can I tell which USB version is installed on my computer? It is pretty simple to locate this information. Navigate to Device Manager and expand the Universal Serial Buss controllers string. The first entry in this string should inform of what version is installed. It will read something like; "USB 2.0 Enhanced Host Controller". Device Manage can be accessed by going to Start>> Control Panel>> System icon>> Hardware tab>> Device Manager button 8. USB drive is not recognized Q: When I plug in my USB drive I hear the audible "ding" sound but nothing happens after that. I don't see that the drive is being recognized at all. If I leave the thumb drive plugged in and reboot, Vista will then recognize it. How can I get the system to recognize the thumb drive without rebooting the system? A: There are two methods that I have seen work for this issue: Method #1: Go to Start In the Search field, type in: device manager Open device manager and navigate to your USB controller Right click the drive and select Properties Be sure that the option for "Write Caching" is enabled Method #2: Navigate to Device Manager using the above instructions Right click and Delete all of your USB controllers Reboot Vista Vista will recognize that you have deleted the USB controllers and add the new hardware back to your system. This may fix anything that had been corrupt.

Q: I would like to have a password on my memory stick so that if someone were to plug it in it would automatically ask for a password. Is this possible? A: There are programs that can do this. You can try "Cryptainer". They have a free version and a paid version. In the free version you are limited on the file storage size you can password protect. Alternately, you can zip the files and apply a password to the zip file.
