Storage devices are now capable of storing huge amounts of data …
When you consider the term “mass storage device,” the first thing to pop into your mind might be a 500GB external hard drive or a 100GB USB flash drive.While these are certainly mass storage devices, the mass storage class also refers to smaller storage devices including floppies, CDs, and camera memory cards. Think of it in these terms: if a storage device is capable of transferring files to and/or from a computer, it’s a mass storage device.
Most mass storage devices show up as a drive letter under My Computer when connected to the PC. These devices generally use a file system which allows the operating system to understand the contents and lets the users move, copy, and delete files.
In order for this all to work, a mass storage device driver is required. The device driver explains the hardware to the operating system and gives instructions so that everything works as it should. For example, if you have a digital camera that stores photos on a Sony Memory Stick, the first time that you insert the stick into the memory card reader, your computer won’t necessarily know what to do with it. How will it know that there’s a set of photos stored in a folder?
The mass storage device driver explains it to the operating system. Device drivers are either installed via a disc when you add a new device or pre-installed with the operating system. When you have a Plug and Play device, the New Hardware wizard will immediately recognize it and load the appropriate mass storage device driver.
Occasionally, the system fails. Suddenly, you can no longer see your external hard drive when connected or your MP3 player no longer shows up as a drive letter under My Computer. This can happen for a variety of reasons. Just like any file on your computer, mass storage device drivers are susceptible to file corruption and accidental deletion.
Device drivers are actually programs with many of them containing multiple required files such as DLL files. If your system shuts down unexpectedly, one of these files could be destroyed. Spyware or a computer virus could also damage these files. Another common problem involves uninstalling software and all of its “unnecessary systems files.” Suppose you allow the uninstall program to remove an unnecessary DLL only to find out later that the deleted DLL was in fact a DLL file that was part of the mass storage device driver?
When device drivers are missing vital parts or are damaged, the device no longer works as expected. If you can see the device as a drive letter under My Computer, it should show up under Device Manager as well. Use Device Manager to update the mass storage device driver or troubleshoot the problem. To open this utility, go to the Control Panel and click System, Device Manager. A list of installed devices will show up. Look under Disk Drives to find your storage device. If you are troubleshooting a CD or DVD drive, these are listed under DVD/CD-ROMs.
It’s a bit trickier to troubleshoot removable storage devices because if they are not recognized when inserted into the USB port or card reader, they won’t be recognized by the Device Manager. For example, if you have an MP3 player that connects to your computer using a USB cable and it no longer shows up as a drive letter, it won’t show up under Device Manager either. First, double check your connections. If that doesn’t work, try a different USB port. If that doesn’t work, try launching the New Hardware wizard which is found in the Control Panel under Add Hardware. You may also need to reinstall the software that came with your MP3 player.
You can also try restoring your Windows XP or Vista computer’s device drivers and other settings to a previous state using System Restore. This tool is found under the Start button, Programs, Accessories, System Tools, System Restore.
The manufacturer of your device may also have issued a new mass storage device driver that updates issues or adds new features. Even if your device is working fine, it’s not a bad idea to check for updates periodically as part of a preventative maintenance routine.
