My guess is that the pc is trying to use a drive letter that is already taken. Make sure the drive is plugged in. Goto Start -> run -> type compmgmt.msc and hit enter. Click on disk management. You should see the drive in the list. Right-click the external drive and click change driver letter. choose a letter that is not already taken. that should do it..

Cant detect hdd


Hi Martin...

The problem is being caused by the Logical Disk Manager
Administrative service and possibly the logical Disk Manager service
not being started or the services might be disabled. to solve the
problem, click on the "Start" menu, click the "Run" command, and then type
in the box: services.msc , scroll down until you see both the above services.
right click on each of the services about and select properties, on the
general tab, change the startup type to "automatic" and click the start
button under the service status. do this for both of the services, and
that should will fix your problem."
-------------------------------------------------------------------------------------------------
For Windows 2000 and XP:
Right click on My Computer.
Choose Manage (This will open the Computer Management window).
Go to the Storage category and select Disk Management
Right click the new drive (usually listed as Hard Disk 1) and "initialize"
You now have the option to partition and format the drive.
The default settings of Primary Partition and NTFS- Quick Format are recommended for most users.

-------------------------------------------------------------------------------------------------
External hard drive can not be recognized, are more common on computer
failures, what's the reason caused this failure?
1, Setting the CMOS parameters
If you never used the USB external device, there may occur the case:
The system can not detect USB hard drive even if the driver is properly
installed, which was mainly due to the motherboard CMOS default port is closed, if not set to
open state, it naturally Windows can not detect the external hard drive. In order to solve this
problem, we can re-boot into the CMOS settings, and set "Assign IRQ For USB" to "Enable" in
"PNP / PCI CONFIGURATION" column, now the system can be assigned to the USB port available
interrupt address.
2, Power shortage
As the USB drive need to consume some power when it at work, if directly through the USB interface
to take power, the power supply may be not enough. Thus, almost all of the external hard drive
comes with a separate external power supply or a PS2 keyboard to take power transfer interface,
at this time you should connect external power supply or through the transfer cable ps2 connected
to keyboard to ensure that it have provided adequate power to the external hard disk,
recommended that you should ensure the external hard drive have adequate power supply when you
use it, otherwise, the external hard disk is likely to be damaged due to insufficient power
supply.
3, USB extension cable fault
USB interface type does not match the external hard disk interface ,this case caused it can not
be used. For example the standard USB interface of the computer configuration is 1.1, while the
external hard drives purchased are USB 2.0, which requires the cable connected computers and
external hard disk must support USB 2.0 standard. Because high-speed mobile device plug in a
low-speed hub, the device may not be properly installed, and some people use external hard disk
while using USB flash drives, For convenience, they directly used USB 1.1 standard cable that
supplied by USB flash drives, as a result, the USB 2.0 standard hard drive not be recognized
correctly. Just replace it by the USB 2.0 standard cable can solve this problem.
4, Windows version is too low
Pre-Windows 98 operating system does not support USB peripherals, so in any case to install the
driver, set the CMOS parameters are unable to make normal use of external hard disk. In this
case, one solution is to upgrade the operating system up to Windows 98, another way is to
Microsoft's official site, download the appropriate patch to make it can identify mobile hard
disk.
5, The system is set incorrectly
When installed driver, the external hard disk icon will be seen on the Device Manager for some
Windows 98 users, but the Explorer does not include the corresponding letter identification,
which is improper system settings. In the Device Manager, double-click the Hard Drive icon, and
click the pop-up window in the "Properties" button, and you could see disconnect, could be
deleted, synchronous data transmission and Int 13 unit four options, of which "could be deleted "
is no tick in front of the system, and simply check this option to restart your computer, you can
see in the Explorer, the new external hard disk drive letter.
While the failure of the external hard disk does not recognized are more the reasons, but
generally not the USB interface or external hard disk's own fault, so it requiring us to consider
some more from around the association when exclude it, I believe you can successfully use the
external hard disk.

Hi I had the same problem and solved it like this assuming that you are running windows xp

With your external casing powered-up (it does not get power through USB does it?) and your WinXP
PC running, plug in the USB.
You should hear 'chime', what happens then?
If harddisk is recognised here, but does NOT have a drive-letter and cannot be seen in Windows
Explorer, the answer is in Windows Disk Management
...
Go Administrative Tools > Computer Management > Disk Management. ( on left column)
Maximize this page. Physical Drives appear at the bottom; Logical Drives at the top.
Hopefully your drive will appear at the bottom (physically), you must then 'import' it into the
Windows installation
; Windows will put its 'signature' on the drive and assign it a logical drive letter :^)
you can try to format it here if it is new and has no info on it , check back to My computer and see if present.

How do i get my computer to use my external hard drive which i just installed


Which Operating system are you currently using? By default XP/Vista/7 should have generic drivers sufficient for using the device as external storage, To Check and make sure the drive is being properly recognized simply double click on the "My Computer" icon on your desktop if using windows XP. Or in Vista/Windows 7, click on the Start Button and then scroll over to Computer and Click. the hard drive should be listed in there. Take note of the drive letter . If you'd like to save items to it simply save to the new drive ( when within the program of your choice, Word, Windows Media Player etc ) by selecting the new drive in the "Save To" Window. ( Be Default most windows systems should store all information on the C:\ Drive ) your new external drive should be listed with a different letter ( F:\ G:\ etc )

Hard disk


Before formatting the drive, be sure to back up any data from the external hard drive that you want to keep. If you want to make your external hard drive bootable, make sure the "File System" option on the "Format" screen matches your operating system. For Windows XP, the file system should be NTFS, while for Windows 98, it would be Fat 32.
Step1 Attach the external hard drive to your computer with the supplied cables. Most modern external hard drives are attached via one of the USB ports on your computer. Older drives may be attached via either the serial port or the parallel (or printer) port.
Step2Click on "My Computer" to see if your computer recognizes that the drive has been installed. If the drive is not showing, reboot your computer and check again. Step3Right-click on the letter that corresponds to your external hard drivemag-glass_10x10.gif. This will most likely be the letter "E" or higher, as your primary drive will be "C" and your CD or DVD drive will be "D." Step4Click on "Format" from the option screen that is displayed. Step5Choose the options you want from the "Format" screen. In most cases, the first three options should be left as is. You can give the drive a volume name in the text box that is provided, if you desire. Step6Click on the "Start" button to begin the process. When the formatting is complete, the external hard drive will be ready for use.
