Universal Serial Bus (USB) flash drives are currently the most common form of portable data storage device. Questions about USB drives belong here.
1,651 Questions
What is the storage capacity of a flash memory stick?
USB flash drives, also called memory sticks, come in a couple different sizes including 4, 8, 16, 32, 64 GB. Some are even bigger than these, you can get a 1 terabyte usb flash drive for about $1,000. Most people tend to get flash drives between 4 and 16 GB
Solid state drive
How much capacity can a USB flash drive hold?
It depends on how many gigs the flash drive can hold. If you are windows, here is a good way to figure out how much if it isn't on the actual flash drive: first open up windows explorer, and on the left hand side it should say favorites, library's, and computer. Click on computer, and then right click click on the flash drive that you want to know the memory for. it should show you a pie chart of how much the device has on it, and has left.
How do you recover flash drive files?
You have almost much chances to recover lost files from USB flash as long as the user do the right things. By relying on a USB flash drive recovery program (see related link) users can retrieve USB files deleted, formatted or lost due to any reasons provided that the data contained in the files are not overwritten (by new data) which means you'd better immediately stop using the flash drive in case you may ruin the chances of USB flash recovery.
Removable media and non-removable media?
Removable storage media refers to CD's, DVD's, Floppy discs, USB drives. Non-removeable storage media refers to RAM, and Hard Drives. So where the storage media's are found depends upon which you are 'talking' about; but generally non-removable inside the computer, removable outside of the computer.
How do you remove write protection on a compact flash card?
Removing Write Protection from a Flashcard Look on the card, somewhere there sound be a little "lock" slide, much like on a floppy disk, make sure this "lock" is on the side where the card can be written on. This is hard to explain with no pictures.
If this does not work, here you go: This slider slides on its own when you put it in the computer sometimes. You may slide it again and again into the unlocked position and keep getting the "this disk is write protected" error. In this case, if you don't want to purchase a new one, try this:
Using your fingernail, or something similar, slide the fingernail along the side with the slider of the cards crease where it closes, popping it open somewhat. The write protection slider should fall out, if not, open the card enough to just pull it out. It is NOT firmly attached to the inside of the card, so this should be easy. THEN, here's where oldschool meets "NEWschool" get a piece of tape (semi-transparent scotch tape is good, it has to be really thin tape) and wrap it around the area you just made devoid of the write protection slider, carefully not putting the tape on the metal contacts. If you're not sure what I'm talking about, ask someone who used to record their own cassette tapes. You're removing the write protection and making it recordable again. HOWEVER, this is a last resort to buying a new card reader, because you ARE making it possible to delete stuff with no problem.....which for some can be a problem.
How can I get information off of my flash drive?
If you are using a fairly recent edition of Windows and have the appropriate drivers and a working USB port. Plug in the flash drive to a USB port. If you are not prompted to open up the folder then select My Computer either located on your desktop or immediately in your start menu at the bottom of the screen. There should be a number of drives available to choose from, the new one and probably the last one will be the one you want. On some editions it will identify it as portable media.
What are the advantage and disadvantage of primary storage device?
the advantage of primary storage device is
1. a store data temporary when a computer is on example ROM and RAM
2.Is used to store data while a computer is turn on or in use
3.It help to determine the number of characters entered on a computer when a processed data
How much is 4 GB storage in flash drive?
4 GB stands for 4 billion bytes. A byte is bits. A bit, is the smallest unit of information in a computer, it has two possible values, 0 or 1. Put 8 of them together and you have a byte which can hold 256 values. The computer billion is not equal to a decimal billion. A KB, or kilobyte, is 1024 bytes, rather than a 1000. So 4 GB is actually 4,294,967,296 bytes.
USB is an acronym for Universal Serial Bus, the successor to earlier computer peripheral connections such as parallel and serial ports. It is an interface (like Firewire) that connects a wide variety of plug and play devices to the computer. These devices can be connected and disconnected without the need of a restart of shutdown of the PC. USB devices include external HDD's, the USB mouse and keyboard, flash memory devices, and printers.
USB 1.1 is obsolete.
USB 2.0 is currently the most popular interface used.
USB 3.0 is out, but still in its early days.
With each USB version release comes new features, such as backward compatibility with previous standards and speed enhancements.
How do you remove write protection from a mini SD card?
Removing the Write Protection Depends on the Source of the Problem.
Broadly speaking, it can be any of the following scenarios
- There is a write-protection tab on the mini sd card HOLDER. Every time you insert this into your PC or card holder, this tab slides to the write protect position. Either keep resetting, inserting & reinserting until it doesn't slide or tape it down.
- There is nothing wrong with the mini sd card. Simply locate the write protection key and push it.
- The mini sd card has some error: Go for a low level formatting.
- The card has virus: Remove the virus. The link for the steps is present in the related link at the bottom of the article.
There is an easy way to solve this problem: Simply put the yellow lock in the middle of its slider. No sticky tape required, as shown below. But if your still having the same problem i suggest you try the sticky tape.
Problem is only that small moveable yellow lock switch is not making, just put sellotape over it maybe two layers needed to make switch.
Even though what is written below may work, the problem is probably that on the card reader (if you have one) there is a small switch that has lock written on the side. If this is pushed down, the drive is write protected, push it in the opposite direction and it may fix your problem I had the same problem with several cards but eventually found a way around it. DON'T buy a new one!
Make sure the SD card lock is 'off' and then use thin, opaque sticky tape (ie non see-through; eg insulation tape) to cover the whole gap but keep clear of the metal contacts at the back.
Your card should work fine now.
Additional Information:
- Reason #1: The mechanical lock switch accidentally moves to the "locked" position during insertion due to the poor quality of the switch. Hence, by taping it, you are actually preventing the lock switch to travel towards the lock position. i.e. downwards.
- Reason #2: If the above fails, it is likely your SD card reader/writer's fault. But don't discard it or buy a new one yet. Allow me to explain the mechanical design of the SD card lock mechanism. So that you may choose to repair it if you want to. You will need a small paper clip and screw-driver to open your card reader. (Don't proceed if your card reader is still under warranty, please return/exchange with manufacturer) There is a mechanical switch very much like a micro push button (I wish I could show you the picture/drawing). Anyway, depending on the position of the lock switch. You either push or release this micro push button inside the SD card reader.
Due to mechanical wear and tear, or some forceful insertion of the SD card, the micro push button is in its "open" circuit position, i.e. write-protected. In order to make the SD card reader writable, we will need to "close" the circuit. (Note: this is an irreversible process as I will be telling you how to remove the write-protection feature of your SD card reader. Once you do this, you would be unable to use the SD card lock switch to lock your data. So, just be careful not to accidentally delete your data)
To proceed, you need to remove the main circuit board from the SD card reader/writer enclosure. The location of the micro push button switch is the same location as the unlock position of the SD card when inserted in the SD card reader/writer. From the BACK of the exposed SD card reader, insert the unfolded paper clip (same way when you try to poke something like a device reset button) except, that it has to be long enough to allow the micro switch to touch together for contact. Then insert the SD card. Once the contact is "closed", your SD card reader/writer can write again. I understand that without a drawing, this may not be very helpful. Please provide suggestions or better explanation if you can. Thanks.
Or, just tape the lock switch to unlocked. This also works for SD cards in normal size. back up all the files u have on ur card then follow these steps
1. Go to Control Panel
2. Go to Administrative tools
3. Go to Computer management
4. From the tree menu on the left select Disk Management
5. Now on the right side you will have a list of all storage devices connected to your computer. Select the one that is your mini SD card. BE CAREFUL WHEN CHOOSING THIS BECAUSE YOU COULD FORMAT YOUR HARDDRIVE. Double check the name in My Computer
6. Right click on the SD card and select format. A new window will pop up showing format options. Select FAT32 from the file system drop down and check the quick format option and then click on OK
7. Enjoy your mini SD card without that annoying write protection
How do you save emails to thumb drive?
The best way to save email to your hard drive is to convert the email (or emails) to a file type that can be easily stored or moved. There are two common file types for this process: PDF and pst. A pst is created when you use and offline mail client, like Outlook, to backup your email. A PDF can be created from your email in several ways. You can download one of many different PDF printers, or use an online site, to convert and export your emails to PDF for backup. See Sources and Related Links for more information. The benefits of creating a PDF is that most smart phones and tablets are also capable of reading PDF file, while a pst file is the easiest to create when using an offline mail client. Consider looking at the Related Questions on 'How to backup emails?' as this depends on the type of email account and if there is already an offline email client on the hard drive.
Where is drive e on your computer?
The disk drive with the logical drive letter H: can be almost anything; it can be a CD drive, a network share on a server someplace, or a flash drive. It all depends on how you define it.
One of the more common examples of drive letters in the "G" through "J" range are sometimes the multiple slots used by card reader devices. These may include SD chips or CF cards such as might be used by a digital camera.
In many cases, right-clicking on the drive letter in Windows Explorer will give you some information. For example, if "Eject" is one of the options, then this is almost certainly a CD device. Select "Eject", and see which device bay opens.
How many movies can be downloaded in a 2GB pen drive?
That, of course, depends on the size of your flash drive. A typical DVD quality movie would range from 700 Mb to 1 Gb in size. Note that the size mentioned on your flash drive is always a bit more than it can handle!

Most computer hard-drives are labelled C:
The recovery partition is usually labelled D:
The internal CD or DVD drive is usually labelled E: and
Removeable storage usually gets the label F:
At least - that's how the drives on my laptop are labelled !
USB flash drive does it make computer go faster?
No, Depending on what processor you have and how much ram you have can depend how fast your computer is. also a hard drive RPM speed as well.
Edit: Windows 7 has a feature called ReadyBoost that can increase your RAM by using a USB Flash drive. It only works if your computer would benefit from its use (e.g. you are using a lot of virtual memory, and your hard drive is slower than the USB port). When ReadyBoost is operational, it will increase the speed of your computer by reducing hard drive virtual memory swapping. So the answer is actually "maybe."
How do you save a program to a USB or CD?
While you can install computer software from a CD or DVD onto the local hard disk, you cannot normally reverse this process. Installation typically is more than copying several files into several places, and it is those "other tasks" that cannot easily be reversed. You can uninstall the software through the means provided and re-install it later, provided you still have the installer and all license keys and/or serial numbers. Manually removing portions of some unwanted software by removing or deleting files from the hard disk is NOT RECOMMENDED. At best, the application in question will no longer work. At worst, other applications and components may also suffer from this move. The "other tasks" that are typically done during software installation, in addition to the copying of files and data, include the registration of various aspects of the installed software within the system. Microsoft Word, for example, registeres the .doc file extensions such that you can double-click a .doc file, and Word opens. Many other, more complex, registration steps are typically implemented by modern software.
Is a USB Flash drive an input or an output device?
A USB Flash drive is considered a storage medium. Data can be both read, stored, and sent to / from a USB Flash drive, but it does not in itself input or output any data.
Is a flash drive the same thing as a external memory card?
yes, external memory counts as portable/External Hard drives, USB flash sticks/drives, SD cards, CD's/DVD's and floppy disks (ancient but still count :P). Anything that you can put files,pictures, movies, etc on counts as external memory.
What to do when a usb port on motherboard is failing?
The key to this question is that it is "a port" not all the ports. Updating the BIOS is not likely the best answer. The book this question comes from actually has the answer but many people are not finding it because it is in a blue box. The answer is to disable the port in the BIOS or by jumper and add an expansion card.
<Old answer> upgrade the BIOS or download the latest drivers
What the speed for hi speed USB?
Up to 480Mbits/second, and being increased over time with improvements.
Can you download movies from harddrive to a flashdrive?
Yes. But do to space considerations, as well as the relatively slow speed of writing to a USB drive, you may want to consider a different medium.
