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 to Install an Operating System on an External USB Hard Drive:



You may have an external hard drive you want to use for more than just document backup.
In this situation, you can install an operating system onto your external hard drive. By doing so, you will be able to run your external hard drive as a fully functional operating system.
If your primary hard drive ever crashes, you will have a backup option unavailable to those who simply use their external hard drives as file and document backup.

1) Plug your external Hard Drive into your Computer using the USB cable. Insert the installation disk for your Operating System into the CD/DVD Drive. Turn on or restart your Computer.

2) Boot from the installation disk. You may have to press a key once prompted to boot from the installation disk.

3) Accept the license terms and conditions. Read through these carefully if you wish to understand your legal rights as a user. If you disagree with these terms and conditions, you may want to purchase a different Operating System.

4) Choose your destination drive. Your external Hard Drive will likely be the E: or F: drive. By default, the C: will represent your main Hard Drive and the D: will usually represent your CD/DVD Drive.

5) Begin the installation. Your external Hard Drive will install the Operating System. You will now be able to run that Operating System off of your external hard drive.


Hope this helps.

Using Windows Disk Management Utility to Manage Internal and External Disks


Disk management utility will help you see all the drives that are connected to your computer, including internal hard drives, CD or DVD Drives, and removable storage like USB sticks and external hard drives. Using this utility, you can check for attached drives that are not visible in windows when attached to your computer. You can also format drives, change drive letters, mark a partition as active and delete partitions. A word on caution about using the Disk Management Utility: This utility can cause destruction of data. If you are not sure of what you are looking at and uncomfortable with using this utility you should consult with an advanced user before making any changes to drives using this utility.


The Disk Management utility can be accessed in two different ways.
#1- You can open the Control Panel,
Click on Administrative Tools,
Click on Computer Management and the Computer Management window will open.
#2- Right click on you “My Computer” Icon
A menu will open
Chose “Manage”
The Computer Management window will open

The Computer Management window is broken down into 3 sections.

The first section on the left side of the window shows a menu. Disk Management is on the lower portion of the menu.

The right side is separated into two sections, top and bottom. The top portion shows a list of active drives on the computer. The lower portion shows all drives connected to the computer. CD or DVD drives that have not disk will not show as active drives on the top section, but can be seen in the lower section.

The lower section will show the drive description, drive size and drive condition (online or off line) in small box on the left side of that section. Disk drives will designate a “Drive” and a number. Drive 0 is usually your internal hard drive. Then it would list drive 1, drive 2, etc, depending on how many internal and external drive sources you have connected to your computer. Then it will list your CD drives and generally show their drive letter assignments.

Next to the smaller section described above, is a larger section which shows the driver letter, size of the driver and condition (if working correctly will show “healthy”)
This is the area you can right click and get a menu that will allow you to open, explore, mark the partition as active, change the driver letter, format the drive or delete a partition. (A note of caution here. Changing the driver letter on your main hard drive partition will cause windows to stop functioning. The main hard drive, or hard drive partition, is normally given the letter “C”.) A hard drive may show two or more partitions with separate drive letters designated for each partition.

A drive this is having a problem may show that it needs to be formatted (status as Unformatted). This can be done from this window. An external drive, whether it is a hard drive or CD/DVD drive, can have the letter designator change done if you want to organize your external drives. There are times when a drive will not show up because the drive letter that they are programmed to use are taken. Most USB drives are programmed to us the letters “F” or “G”. In this area, you can assign the USB drive any drive letter that is not being used and this will make it visible in windows.

My desktop model is Compaq SR5213 with 250G harddisk. Recently, I would add a new internal hard disk (3.5", 1 TB), is it possible? As I don't want to buy a external hard disk. thanks


You can add 1 TB hard as additional to 250 GB Hard disk. You did not need to buy a external hard disk. Both hard disks will work together and make total hard disk space- 1.25 TB.

Hard drive failure in system less than 2 years old!!


Since you are comfortable with working inside your computer, the best thing to do now is to purchase an external enclosure for your type of hard drive, SATA or EIDE.

Alternately you can use a live linux cd, boot up with that, and transfer your data to an external drive.

Once your data is safe, try booting to the Windows cd and attempt a repair installation.

And finally, yes, hard drives can go bad in 2 years or less.
