Typically USB flash storage devices are small, lightweight, handy, low cost, rewriteable and removable; USB flash drives are NAND-type memory, a data storage device integrated with a USB interface. There are several advantages over other portable storage devices; predominantly on conservative storage devices like floppy disk, USB Drives are faster, grasp more data, and are considered more dependable than any other storage devices available in market today.
By comparison to 88.2 million USB flash drives shipped in 2005, and 115.7 million shipped in 2006, Gartner Dataquest statistics shows average 100% raise on number of USB memory drives user worldwide. SanDisk ranks No. 60 on FORTUNE’s 100 fastest-Growing Companies List.
USB flash drives are a relatively dense form of storage, even the cheapest and smallest flash memory chips will store dozens of floppy disks worth of data. Most flash memory chips today can hold more data than a CD. Top of the line flash drives can even hold more data than a DVD. CompactFlash storage devices ready to hit the market soon include 64 GB’s of PRAM memory. The most common USB flash memory devices are 1GB in size Recent industry reports indicate a rise for the first time in over a year for these 1GB USB storage devices due to their popularity. The flash memory market had recently only been experiencing drops in prices. This is an indicator that the profit margins on memory products may see much more positive profits this quarter.
Most modern operating systems can read and write to USB flash drives without any supplementary device drivers. Instead of exposing the composite technical detail of the underlying USB flash memory devices, the USB flash drives export a simple block-structured logical unit to the host operating system. The operating system can use whatever type of file system or block addressing scheme it wants.
Most USB flash drives do not utilize a write-protect mechanism. Such a switch on the housing of the drive itself would keep the host computer from writing or modifying data on the drive. Write-protection would make a device suitable for repairing virus-contaminated host computers without infecting the USB flash drive itself.
USB flash drives are more tolerant of abuse than mechanical drives, but the rate of USB flash drive failure under eprovided.com statistic shows 300% raise each year due to quality-control problems, mishandling and an increasing number of poorly manufactured devices on the market.
According to expert Bruce Cullen, president of data recovery services eProvided.com, “Similar to other mechanical storage devices USB flash drives also have mechanical storage and threshold margins, and face issues with potential fragmentation problems. This fragmentation occurs when documents are created and then saved or erased and when the new files are bigger than the available adjacent space. The data in these files is broken up and is randomly placed on the drive cells, resulting files start to become fragmented. Issues related to fragmentation are not known to consumers, so consumers aren’t defragging their flash drives properly.”
Generally a consumer is expected to find that a standard single level cell of a NAND flash drive can acknowledged 100,000 read-write cycles, usually an immeasurable amount of read-writes for common users. Issues like virus attacks, damage causes by extreme heat/cold, power outages, shock, etc. can shorten the life span of the drive or cause it to malfunction suddenly in many cases.
However, the real problem for the colossal rise of USB drive failures is manufacturing & quality control issues; faulty flash drives with poorly manufactured specifications in the market are dominating compared to the quality high price drives with similar configurations.
“I expect a dramatic rises in problems with USB flash drives as there are a lot of mushroom companies growing and manufacturing flash storage devices these days” Bruce Cullen said. “Most of the USB flash storage producers are based in Taiwan, Singapore and China, due to price competition these companies are disregarding quality controls, and due to this price competition even quality manufactures are manufacturing and selling products using low-grade flash memory circuits, capacitors and crystals, resulting in massive increases in USB Drive failure rates and reliability issues. This is creating flash memory technology questions on quality” he further added.

How-To Guide – Block USB Storage Devices on Windows XP
Last Updated on Wednesday, 29 December 2010 02:26 Written by databank Wednesday, 29 December 2010 02:26
Joshua Bulman asked:
This guide is written to help an administrator block the access of USB storage devices in Windows XP. This is particularly useful for large offices who work in data sensitive information, like the Health Care industry.
Setting User Permissions
1. Log into an Administrator account in the desired Windows computer.
2. Open up a Windows Explorer window, and in the address field type: %SystemRoot%Inf
3. Locate the files Usbstor.inf and Usbstor.pnf, select both files, right-click and go to Properties.
4. Click on the Security Tab.
5. In the Group or User Names list, add the user group that you want to deny permissions to.
6. In the Permissions for that group, click the Deny box next to Full Control.
7. Now repeat step 6 for the System Account.
This will prevent any new access to a USB storage device, but if a device is already installed on the computer you will need to complete these additional steps.
These steps require that you modify the registry. This can cause serious problems if you modify incorrectly. You should begin by creating a backup of your registry. This can be restored in the event that you incorrectly modify and cause an error in Windows.
Backing Up The Registry
1. Click Start, Run, and type: %SystemRoot%system32restorerstrui.exe
2. Click OK.
3. On the Welcome to System Restore page, click Create a Restore Point and click Next.
4. On the Create a Restore Point page, type a name for the Restore Point and then click Create. -if you have restores turned off it will ask whether to turn on now, click yes, in the System Properties dialog box, clear the Turn off System Restore check box and click OK.
5. After the restore is created click close.
Changing the Registry
1. Click on Start, Run and type: regedit
2. Click OK.
3. Locate and click the following Registry Key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesUsbStor
4. In the details area, double-click Start.
5. In the Value data box, type 4, click Hexadecimal (if it is not already selected).
6. Click OK.
7. Exit the Registry Editor.
Now the system should be locked from using USB storage devices. Plug in a USB drive and you will see that it will not load. You can check that it does register in the Device Manager but is not permitted to load drivers.
Verifying in Device Manager
1. Click on Start, then Right-click My Computer and choose Properties.
2. Click on the Hardware tab.
3. Click Device Manager.
4. Listed under Universal Serial Bus Controllers, there should be a device with an exclamation mark. This would be the USB drive with blocked drivers.
Restoring The Registry (ONLY use this if you have incorrectly altered the Registry)
Do not use this to reverse the above effects at a later date, as restoring to this date will undo any adjustments in windows between these dates.
1. Click Start, Run and type: %SystemRoot%System32RestoreRstrui.exe
2. Click OK.
3. On the Welcome to System Restore page, click Restore My Computer to an Earlier Time and click Next.
4. On the Select A Restore Point page, click the system checkpoint you recently created. In the On This List Select the Restore Point area, click “Guided Help (Registry Backup)” and click Next.
5. A system message may appear that list configuration changes to be made, click OK.
6. Confirm Restore Point Selection, Click Next.
7. Windows will restart, click OK on the confirmation.

3 Reasons Why the USB Mass Storage Device Driver is Important
Last Updated on Monday, 27 December 2010 09:17 Written by databank Monday, 27 December 2010 09:17
Logan Albright asked:
A USB Mass storage device driver is the part of the software that helps to power those mass storage drivers. For one thing, we need to know what exactly is the USB drive and what kind of applications can be associated with this. Universal Serial Bus flash drive bays offer prospective advantages fin de si?cle previous portable storage devices, particularly the diskette magnetic disk. They have a more compact shape, operate faster, handle a great deal more data, have a more durable conception, and function more faithfully due to their want of running components. To Boot, it has changed state increasingly common for computing machines to be sold without floppy disk drives. USB interfaces, on the other hand, appear on almost every current mainstream computers and laptop computer.
These types of drives use the Universal Serial Bus mass memory standard, sustained natively by contemporary controlling systems such as Microsoft Windows, Mackintosh OS X, the Linux systems, and other Unix-like systems. Universal Serial Bus forces with Universal Serial Bus 2.0 endure can also operate quicker than an optic disc drive, while storing a extended measure of information in a much minute place. Nothing in reality moves in a standard small memory flash drive: the term force persists because computing machines read and write flash-drive data using the identical scheme commands as for a mechanical disk drive, with the storage coming out to the computer operating system and interface as merely another drive.
A standard small memory flash drive comprises of a minute printed circuit board preserved within a reconstructive, metal, or rubberise case, robust enough for holding with no additional protection-in a bag or on a key string, for instance. The USB connexion is protected by a extractible cap or by drawing back into the body of the drive, although it is not in all probability to be notorious if exposed. To The Highest Degree flash drive bays use a measure type-A Universal Serial Bus link providing plugging into a port on a microcomputer, but drives for other interfaces also endure. The first reason that you need to know that the device driver is important is because it is able to ensure the reliability of the mass storage device driver.
The next reason you need to think about is of course, the overall speed of the device, as the best drivers would allow you to be able to capitalise on the true speed of the USB port and the driver. The last reason you need to think about is that so that you can avoid some of these conflicts and of course allow Windows to actually detect and recognise the device in the first place. These are the reasons why you should always have the latest USB mass storage device driver on hand, because you would always want the storage driver to work at all times. The good news is that you can easily find these drivers online, and all you need to do is log on to a search engine.
