USB Flash Drives
There are many different names, shapes, and capacities for USB
flash
drives. Each company calls it something different,
including flash drive, flash pen, jump drive, thumb drive, key drive, and mini-USB
drive.
All have the same
kind of rectangular connector under the cap. This connector can only plug
in one way. Do not force it!
All are small, about the size of your thumb or a large car key, and plug into a
USB port on the computer. No drivers are needed for Windows Vista, XP, 2000, or
Me. Plug it in and the computer reports a new drive! Older
versions of Windows need to have drivers installed.
Such small flash drives can have large storage capacities, from 8 MB to 4 GB or
more! Much better than a floppy disk!
Some flash drives have
a tiny, hard-to-see switch that you can use to prevent writing to the drive.
Some flash drives include password protection, encryption, and the ability to run
software right off the USB drive. So cool!
Floppy Disks
A floppy disk does not look very floppy. But what is
inside the plastic case is very floppy indeed. It is a thin Mylar disk
that has magnetic properties. Your floppy drive "writes" data onto the disk
by setting the direction of the magnetic particles.

Step-by-Step: Using a Removable Disk
|
 |
| What you will learn: |
to insert & eject
to label or mark
to view the contents
to write-protect
to respond correctly to an error message |
Start with:
These lessons will use the floppy disk icon
to mark
steps where you need to save to whatever removable media you are using.
Insert & Eject a Floppy Disk
If you do not have a floppy disk drive on your computer, you can
skip to the next section.
-
Find
the floppy drive on your computer. It is a slot with a button and a
small light which comes on when the drive is accessing a disk. The
button will stick out when there is a disk in the drive. [Old drives have a lever instead of a
button.]
- Put a computer disk label on your floppy disk if it doesn't
already have one. Please use a label designed for floppy disks.
Other kinds of labels may come off inside the drive, with expensive
results.
Be careful when
you put the label on. It should not cover the holes or touch the metal
parts of the disk. Be sure all the label edges are stuck down tightly so
the label won't come off inside the disk drive!
-
Write
your name on the label and the class it is for. This label will help you
keep track of what is on a disk as well as identifying your disks to
others if you lose it. Some computer disk labels wrap around the top of
the disk to the back. Some just fit on the front.
We will call this your Class disk, meaning the disk to
which you are currently saving documents. You will use this disk to
practice working with files and folders.
If you are using the older
5¼" disks, be sure to write on the label BEFORE putting it on the disk.
It is easy to damage the insides of this larger type of floppy by
writing on it. A felt tip pen can be used after the label is on the
disk. Never use a pencil or ball-point pen on a 5 ¼" disk.
- Insert the floppy disk into the floppy drive, with the label
side up and the side with the round metal part down. Be sure the disk is
entering the slot straight and don't force the disk in. Only one will
fit in at a time!
The eject button should be sticking out when the floppy disk is in
the drive.
Be careful when inserting and removing
disks so that you don't snag the metal slide and bend it. That could keep
the disk from working in the drive.
- Now eject the disk by pushing the eject button on the
drive. See how easy this is!
Insert & Stop/Eject USB Flash Drive
If you are not currently using a USB device to store your documents,
read through this part anyway! You will be using such devices in the
future.
-
 Locate
the USB ports on your computer. There may be ports on the front,
on the back, on the monitor base or edge, or even on the keyboard.
(Keyboard ports may not carry enough power for your device.)
-
Remove
the cap from your USB flash drive.
- Insert the USB flash drive into the USB port. Be
careful not to force it in the wrong way!
Windows recognizes that you have connected a USB device.
Any
of several events
may happen:
- a notification sound plays
- a popup message appears, notifying you of that a new device has been found
- a message tells you that drivers are being installed.
- a search progress bar appears as Windows looks for an AutoPlay command
- a dialog offers you several choices of what to do next, including
Open folder to view files using Windows Explorer
and No Action.
- new icon
appears
in the notification area of the Task Bar
- a new window displays the drive's contents
- If you do not have the new icon
in the tray of the Task Bar, skip to alternate
method.
-
If
you have the new icon
in the tray of the Task Bar, left click it. A menu
appears that lists USB devices that are currently connected.
A printer that is connected
to the computer with a USB cable may not show in this list. It probably
will if it can read files directly from a camera or if it has a port for
inserting the storage card from a camera.
-
Click
on your USB Mass Storage Device.
A popup message tells you when you can safely remove the device. The
light on the drive turns off for most drives. If a window was showing the
drive contents, it closes automatically.
In
Windows Vista: If the contents of the device are displayed in a
window, Vista will not let you 'safely remove' the device. You must
close any such windows as well as any open documents from the device.
Problem:
Message - Cannot remove the device
If a file on your device is in use, you should not remove the USB device
yet.
Solution: First close any open documents and Computer windows
that display the contents of the drive. Then try again.
 Problem:
You don't know which USB device to choose
Solution: Right click on
the Safely Remove Hardware icon. A popup menu appears with only one
command, Safely Remove Hardware. Click on it. A dialog appears that
lists the USB devices. Choose one and click on Stop. Another
dialog appears with several names for the same device. Now you should be able
to tell if this is the device that you want to stop. If not, Cancel this
dialog and choose another device in the previous dialog until you find
the right one. Then you can click the Stop button. <Whew!>
- Verify that the drive light is off.
- Remove the USB drive by pulling it out of the port.
Alternate methods to safely remove USB flash
drive:
Method 1: Open a window that shows the drives on the computer
(My Computer/Computer/Explorer). Right click the drive
and select Safely Remove, if it is available, or Eject. Wait for your drive's light to go off. Then remove
the device.
Method 2: Log off the computer. Verify that the device's light
is off. Then remove the device.
Why
go through these steps? What not just pull a USB flash drive out of
its port?
- If the device is in the process of writing, you can corrupt your
file and even damage the device permanently.
- The computer may not recognize the next device you plug into that
port. Rebooting the computer clears up this issue but logging off and
back on again does not.
- The computer may not let go of the drive letter it assigned to the
USB drive. There are only so many letters available! Rebooting does not
usually clear up this issue. It can be tricky to fix.
View Contents of a Floppy Disk
Start with:
,
(removable disk is not in the drive yet)
If you don't have a floppy drive, skip to the
next section.
-
Double-click
on the
My Computer icon on your desktop. A My Computer window opens that shows
icons for each drive on the computer and for certain special folders.
-

Double-click on
the 3½"
Floppy (A:) drive in the My Computer window. The icons are a little
different in each version of Windows:
Win98
,
WinXP

(Be sure the drive is empty for this step!)
You
will see the failure message at the right. You will hear the drive
trying to access the floppy. (A scary sound when not expected!) You may
hear the computer's error sound. This message usually just means that
the disk is not in the drive.
Problem:
You get a message when a disk is
in the drive that says the device is not ready or tells you to insert a
disk. It may mean that there is either a:
- Physical problem:
Dirt inside the cover or other
physical damage. Perhaps the metal slide is stuck or the disk won't
spin inside the plastic case because of grit inside. (Ouch!)
What you do:
Eject the disk and move the metal slide
back and forth a few times. Turn the disk to the back and rotate the
metal circle a time or two in both directions to be sure it is
spinning smoothly. If all seems well, insert the disk and try again.
- Data problem:
A magnetic field has scrambled or erased the
data on the drive without doing physical damage.
What you do:
Re-format the disk and use it again, if
there is no physical damage. Your data is lost.
Sometimes
disks
formatted in one computer are indigestible to another one for no
apparent reason. Don't assume that your data is lost forever until you
try the disk in the original computer.
Insert
the Class disk into the drive and
click on the
Retry button in the error message.
The
My Computer window that appears will be blank - if the floppy was blank
to begin with!
Always view the
contents of a floppy before formatting! It is very easy to grab the
wrong disk.
View Contents of Other Removable Media
If you are using a removable disk other than a floppy disk, the drive
may not show in My Computer or Computer until you actually insert your disk. It
depends on the kind of drives you are using. Internal Zip drives will show up as
well as card readers (which read media cards for cameras). USB drives will
not show up until a flash drive is inserted into the port.
- Without inserting your removable media yet, open a My Computer or
Computer window by either:
Double-click
on the
My Computer icon on your desktop.
OR
Start menu > My Computer or Computer
A window opens that shows
icons for each drive on the computer and for certain special folders.
- Look for an icon for your removable media drive. If
you are using a permanently attached drive like a Zip drive, you will
see an icon for it. If you are using a USB flash drive, you will not see
it in the list yet.

The example above shows 5 hard disk drives, which are actually separate
partitions of a single physical drive. Under Devices with Removable
Storage, there is a floppy drive A:, a CD drive I:, and several removable
disk drives, H:, J:, K:, and L:.
H: is a Zip drive that is installed in a bay in the computer. J:, K:,
and L: represent different slots in a USB device that reads three
different media used in cameras. Drives H:, J:, K:, and L: are showing even
though they do not have media in them at this time.
There are no USB flash drives are showing because no USB drives are
currently connected. A confusing difference!
- Insert your removable media. An icon
appears with a drive letter that depends on how many other drives you
have. A USB drive can have a letter assigned permanently.
You
should hear a sound that indicates that Windows has found a new device. AutoPlay will look for an
AutoRun command. In some situations, a
window will open to show the contents of the drive.

My Computer window now shows a USB drive.
Problem:
Message - the
drive needs to be formatted
This message may be sent because there is a serious problem with your disk,
but the problem might be
with what you connect it to or insert into.
What you do:
Clean the parts of the disk and of the
drive or port of all dust or particles, try to
carefully straighten the bent connector, and try again.
What you do:
Re-format the disk and use it again, if
there is no physical damage. Your data is lost. Be SURE that the
problem is with the disk and not what you plugged it into!
Reformatting
a flash drive is not recommended unless absolutely necessary.
Sometimes a flash
drive is not readable in one computer but can be read by another computer.
Be SURE your drive is dead before trying to reformat. Remember also, if a
flash drive was removed incorrectly (not with Safely Remove Hardware),
the computer may fail to see a new device on that connector until
after the computer has been rebooted.
Reminders on care of removable media
- Label it with your name! If the device is too small to
write on, put a file on the device at the top of the folder tree that
tells whose device it is.
- Keep away from heat.
- Keep away from magnets, even small ones!
- Keep away from smoke, dust, crumbs and dirt.
- Don't bend or put heavy weights on it.
- Don't spill anything on it.
It's
not a good idea to carry removable media loose in your purse or in your
pocket. It's too easy to damage one this way.
