Flash memory, flash drive, pen drive and memory drive are just some of the names that are used to refer to USB flash drive. It is a compact device that was developed to be a secure and safe data transfer as well as data storage gadget. While this travel data storage device may seem to be perfect, it is still possible that it might corrupt your data. Just like in any other technology, a USB flash drive is also prone to technical problems that often lead to the corruption or loss of data. Assuming that its hardware is undamaged, doing a re-format can solve USB problems.

USB formatting is as easy as A-B-C. First, you have to right click on the removable drive corresponding to where the USB was inserted, and then click on the "format" option. Or you can try using the file system drop down, where options "FAT and FAT32" are available. Choose the FAT option, it will reveal format utilities, then click on the "Quick format" option then press on "start" to initiate format operations. This way, all the data that the USB contains will be deleted, but the errors will hopefully be gone. Usually, errors or malfunction occurs during file transfers or data storage. For simple drive errors, scanning and re-formatting can work. In this manner, all the bad sectors of the USB will work like new.

When formatting does not solve your USB problems, you can make use of an alternate method. For more complicated USB problems, you will need to check the bios first to determine the actual problem. Before doing that, it is advised that you backup all the files from your hard drive to another hard drive, CD or DVD, and then turn off your computer. Insert your problematic USB on the drive port and turn on the computer. When the system bios are prompted, immediately press the F8 key. For some computers, it is the delete key or F2 key that initiate bios checking and take note of the operators that are listed on the screen. Using the cursor keys, navigate the bios and boot the CD drive first, save and then exit. Insert your operating system restore disk, save and restart. Simply follow the cue that initiates installation of your operating system. When the USB disk appears on the list of which drive format comes, then your USB is in the clear.

Depending on the options, you must opt out the re-installation of the operating system at this point. If it is still running, simply quit and leave the other drives alone. Try to reset the computer to boot from the disk instead of the CD drive as before. If your USB flash drive is already usable, it must now be detected in windows. If you fail to do this operating system re-installation, then just continue following the installation instructions. However, never try to install the operating system onto the USB disk drive.

Before going over your USB problems and trying out some troubleshooting tricks, have all your files backed up first, this task is something that must not be taken lightly. Although formatting seems easy, it is a lengthy process that needs to be done by somebody who fully understands the application. If everything else fails, get hold of your USB's warranty so you can get it fixed from customer support.

I was asked in the comments of a previous post how I managed to run multiple versions of Skype at the same time and while answering him, I thought it was worth turning my answer into a post. It isn’t just Skype that this can be used for. You can also use this method to run multiple versions of your favourite instant messaging program (if you have more than one ID) or multiple versions of your internet browser if you have more than one email account with the same provider. For instance, using this tip you can access multiple gmail accounts at the same time.

With the Windows operating system, everything runs under a user account which you log into when you boot up the computer. Say for the purposes of this discussion, my main default user account on my PC is MARK_1. Well when I boot up the PC in the morning, MARK_1 will load and all programs I subsequently use will run under MARK_1.

But I sometimes help out a friend who runs a virtual telephone answering service through Skype. So obviously only one Skype line isn’t going to cut it. To open more Skype lines (without having to log in and out of Windows all the time), here’s what you do :

First, you need to set up more Windows user accounts. To make this simple, I’ll name them MARK_2, MARK_3 and so on. Since I have a German language computer, I can’t really post too many screenshots and I am unsure of the terminology on an English language computer so I will describe it to you in general terms and perhaps you can tell me the exact wording. In the Windows start menu, you have a “System Setup” option and in there is an option called “User Accounts”. This is where you maintain your Windows accounts, including the main administrator account.

Just open that option up, choose the new account option and set up as many new accounts as you need. YOU DON’T HAVE TO LOG OUT OF YOUR CURRENT USER ACCOUNT TO DO THIS! Plus you need to have administrator privileges to set up new accounts. So trying this at work is probably not a good idea as your IT department will probably not appreciate it.

Once the accounts are set up, go to the desktop icon (or the start menu link) of the program you want to start again and choose “run as”. This will open up a sign-in box with a drop-down list of your user accounts (which by now should contain the new ones you have just created). Just choose another account, enter the password (if you set one up during the account creation process) and the program will instantly open again under that new windows user account.

Using this method, I have run up to five Skype lines simultaneously and the ICQ chat program three times (although I am sure more is possible if you have the CPU capacity to support them all). As I said before, you can also use this method to run more than one Firefox browser to check email accounts or perhaps you want to be logged in as two different users in a social network? The possibilities for running more than one Windows user account is endless.

Can you think of other scenarios where running more than one user account would be beneficial? Let’s hear it in the comments!
