How to Fix an Undetectable USB Flash Drive?
- While USB flash drives are a convenient and easy way to quickly transfer large quantities of data in a tiny space, the way that they store data can cause them to become easily corrupted
- If your computer will not detect the USB flash device or will not allow you to interact with the data stored on the drive, you can use the built-in features of your computer's operating system to attempt to fix the problem before resorting to buying a new drive
- Plug the drive into a USB port that you know is working on a separate computer to make sure that the port itself is not causing the problem. Place the drive back into the original USB port if it remains undetectable on another system
- Open the "Start" menu and click on "My Computer" to bring up a new window that lists all of the drives connected to your computer. Take note of the letters assigned to the drives connected to your computer. Click on the blue button at the top left end of the window labeled "Map a Network Drive." Click "Continue" if a second window pops up asking for your permission to open the new menu
- Click the "Drive" button at the top of the new window. Select a drive letter from the drop-down menu that is not already in use, such as "Z" or "M." Click on the "Browse" button and locate the USB flash drive that your computer hasn't been detecting. Click on the drive and then click the "OK" button
- Click the "Finish" button to close the window and map the USB flash drive to your computer. Restart the computer and then return to the "My Computer" menu and check to see if the USB flash device is usable. Navigate to the "Start" menu if the device still isn't working properly, and open "Control Panel."
- Click the "Administrative Tools" link in the Control Panel menu. Click "Continue." Double-click the "Computer Management" link at the top of the menu. Click the "Disk Management" button at the left side of the window to bring up a list of drives on the computer. Right-click the USB flash drive and choose the "Format" option. Click "Start" and wait for the formatting process to finish. Restart the computer and then attempt to use the USB flash drive again
Design and Implementation:
- One end of the device is fitted with a single male type-A USB connector. Inside the plastic casing is a small printed circuit board. Mounted on this board is some power circuitry and a small number of surface-mounted integrated circuits (ICs). Typically, one of these ICs provides an interface to the USB port, another drives the onboard memory, and the other is the flash memory
- Drives typically use the USB mass storage device class to communicate with the host
There are typically four parts to a flash drive:
- Male type-A USB connector - provides a physical interface to the host computer
- USB mass storage controller - implements the USB host controller. The controller contains a small microcontroller with a small amount of on-chip ROM and RAM
- NAND flash memory chip - stores data. NAND flash is typically also used in digital cameras
- Crystal oscillator - produces the device's main 12 MHz clock signal and controls the device's data output through a phase-locked loop
The typical device may also include:
- Jumpers and test pins - for testing during the flash drive's manufacturing or loading code into the microprocessor
- LEDs - indicate data transfers or data reads and writes
- Write-protect switches - Enable or disable writing of data into memory
- Unpopulated space - provides space to include a second memory chip. Having this second space allows the manufacturer to use a single printed circuit board for more than one storage size device
- USB connector cover or cap - reduces the risk of damage, prevents the ingress of fluff or other contaminants, and improves overall device appearance. Some flash drives use retractable USB connectors instead. Others have a swivel arrangement so that the connector can be protected without removing anything
- Transport aid - the cap or the body often contains a hole suitable for connection to a key chain or lanyard. Connecting the cap, rather than the body, can allow the drive itself to be lost
- Some drives offer expandable storage via an internal memory card slot, much like a memory card reader
Size and style of packaging:
- Some manufacturers differentiate their products by using elaborate housings, which are often bulky and make the drive difficult to connect to the USB port. Because the USB port connectors on a computer housing are often closely spaced, plugging a flash drive into a USB port may block an adjacent port. Such devices may only carry the USB logo if sold with a separate extension cable
- USB flash drives have been integrated into other commonly carried items such as watches, pens, and even the Swiss Army Knife; others have been fitted with novelty cases such as toy cars or LEGO bricks. The small size, robustness and cheapness of USB flash drives make them an increasingly popular peripheral for case modding
- Heavy or bulky flash drive packaging can make for unreliable operation when plugged directly into a USB port; this can be relieved by a USB extension cable. Such cables are USB-compatible but do not conform to the USB standard
How much can you store?
Personal data transport:
- The most common use of flash drives is to transport and store personal files such as documents, pictures and videos. Individuals also store medical alert information on MedicTag flash drives for use in emergencies and for disaster preparation
Secure storage of data, application and software files:
- With wide deployment(s) of flash drives being used in various environments (secured or otherwise), the issue of data and information security remains of the utmost importance. The use of biometrics and encryption is becoming the norm with the need for increased security for data; OTFE systems are particularly useful in this regard, as they can transparently encrypt large amounts of data. In some cases a Secure USB Drive may use a hardware-based encryption mechanism that uses a hardware module instead of software for strongly encrypting data. IEEE 1667 is an attempt to create a generic authentication platform for USB drives and enjoys the support of Microsoft with support in Windows 7
- Flash drives are particularly popular among system and network administrators, who load them with configuration information and software used for system maintenance, troubleshooting, and recovery. They are also used as a means to transfer recovery and antivirus software to infected PCs, allowing a portion of the host machine's data to be archived. As the drives have increased in storage space, they have also replaced the need to carry a number of CD ROMs and installers which were needed when reinstalling or updating a system
Computer forensics and law enforcement:
- A recent development for the use of a USB Flash Drive as an application carrier is to carry the Computer Online Forensic Evidence Extractor (COFEE) application developed by Microsoft. COFEE is a set of applications designed to search for and extract digital evidence on computers confiscated from suspects. Forensic software should not alter the information stored on the computer being examined in any way; other forensic suites run from CD-ROM or DVD-ROM, but cannot store data on the media they are run from (although they can write to other attached devices such as external drives or memory sticks)
- Some value-added resellers are now using a flash drive as part of small-business turnkey solutions (e.g. point-of-sale systems). The drive is used as a backup medium: at the close of business each night, the drive is inserted, and a database backup is saved to the drive. Alternatively, the drive can be left inserted through the business day, and data regularly updated. In either case, the drive is removed at night and taken offsite
- This is simple for the end-user, and more likely to be done
- The drive is small and convenient, and more likely to be carried off-site for safety
- The drives are less fragile mechanically and magnetically than tapes
- The capacity is often large enough for several backup images of critical data
- And flash drives are cheaper than many other backup systems
- It is also easy to lose these small devices, and easy for people without a right to data to take illicit backups
Advantages and disadvantages:
- Data stored on flash drives is impervious to scratches and dust, and flash drives are mechanically very robust making them suitable for transporting data from place to place and keeping it readily at hand. Most personal computers support USB as of 2010[update]
- Flash drives also store data densely compared to many removable media. In mid-2009, 256 GB drives became available, with the ability to hold many times more data than a DVD or even a Blu-ray disc
- Compared to hard drives, flash drives use little power, have no fragile moving parts, and for most capacities are small and light
- Flash drives implement the USB mass storage device class so that most modern operating systems can read and write to them without installing device drivers. The flash drives present a simple block-structured logical unit to the host operating system, hiding the individual complex implementation details of the various underlying flash memory devices. The operating system can use any file system or block addressing scheme. Some computers can boot up from flash drives
- Specially manufactured flash drives are available that have a tough rubber or metal casing designed to be waterproof and virtually "unbreakable". These flash drives retain their memory even after being submerged in water, even through a machine wash. Leaving such a flash drive out to dry completely before allowing current to run through it has been known to result in a working drive with no future problems. Channel Five's Gadget Show cooked one of these flash drives with propane, froze it with dry ice, submerged it in various acidic liquids, ran over it with a jeep and fired it against a wall with a mortar. A company specializing in recovering lost data from computer drives managed to recover all the data on the drive. All data on the other removable storage devices tested, using optical or magnetic technologies, were destroyed
- Like all flash memory devices, flash drives can sustain only a limited number of write and erase cycles before failure. This should be a consideration when using a flash drive to run application software or an operating system. To address this, as well as space limitations, some developers have produced special versions of operating systems (such as Linux in Live USB) or commonplace applications (such as Mozilla Firefox) designed to run from flash drives. These are typically optimized for size and configured to place temporary or intermediate files in the computer's main RAM rather than store them temporarily on the flash drive
- Most USB flash drives do not include a write-protect mechanism, although some have a switch on the housing of the drive itself to keep the host computer from writing or modifying data on the drive. Write-protection makes a device suitable for repairing virus-contaminated host computers without risk of infecting the USB flash drive itself
- A drawback to the small size is that they are easily misplaced, left behind, or otherwise lost. This is a particular problem if the data they contain are sensitive (see data security). As a consequence, some manufacturers have added encryption hardware to their drives-although software encryption systems achieve the same thing, and are universally available for all USB flash drives. Others just have the possibility of being attached to keychains, necklaces and lanyards. To protect the USB plug from possible damage or contamination by the contents of a pocket or handbag, and to cover the sharp edge, it is usually fitted with a removable protective cap, or is retractable
- Compared to other portable storage devices such as external hard drives, USB flash drives still have a high price per unit of storage and were, until recently, only available in comparatively small capacities. This balance is changing, but the rate of change is slowing. Hard drives have a higher minimum price, so in the smaller capacities (16 GB and less), USB flash drives are much less expensive than the smallest available hard drives
