External USB disk

Suspect that sPD5110CC has had partition details deleted. Not viewable in Windows. Windows sees the device but cannot access it via explorer. The disk has been used so I know it is not faulty.

Simply formatting the hard drive does not remove all residual traces of the previous installation. When you get to the step for formatting, go to the advanced button and delete the partition that contained windows 8. Then create a new partition in the space, format, and install windows 7.

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.

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.

I was given a computer with a homemade tower... I need to factory reset it but don't know how??


Basically you need the Windows installation CD plus the product installation code. Boot up with the Windows installation CD to install Windows on the hard disk, follow the on screen instructions - delete the existing Windows partition, create a new partition and format the new partition (full NTFS format - not a quick format) and continue with the installation.
Next you need to install the motherboard device drivers, you can download them from the motherboard manufacturer's WEB site from a computer with internet access. Copy these drivers onto an USB memory stick and insert this memory stick into you PC tower and install these drivers.
After installing these drivers you can now connect to the Internet to activate your Windows, You can activate Windows over the phone.

Convert to Basic and Dynamic Disks in Windows XP


Windows XP Professional supports two types of disk storage: basic and dynamic. Basic disk storage uses partition-oriented disks. A basic disk contains basic volumes (primary partitions, extended partitions, and logical drives).

Dynamic disk storage uses volume-oriented disks, and includes features that basic disks do not, such as the ability to create volumes that span multiple disks (spanned and striped volumes).

General Notes
Before your change a basic disk to a dynamic disk, note these items:

You must have at least 1 megabyte (MB) of free space on any master boot record (MBR) disk that you want to convert. This space is automatically reserved when the partition or volume is created in Microsoft Windows 2000 or Windows XP Professional. However, it may not be available on partitions or volumes that are created in other operating systems.

When you convert to a dynamic disk, the dynamic volumes cannot be changed back to partitions. You must first delete all dynamic volumes on the disk, and then convert the dynamic disk back to a basic disk. If you want to keep you data, you must first back up or move the data to another volume.

After you convert to a dynamic disk, the dynamic volumes cannot be changed back to partitions. You must first delete all dynamic volumes on the disk, and then convert the dynamic disk back to a basic disk. If you want to keep your data, you must first back up or move the data to another volume.

After you convert to a dynamic disk, local access to the dynamic disk is limited to Windows XP Professional and Windows 2000.

If your disk contains multiply installations of Windows XP Professional or Windows 2000, do not convert to a dynamic disk. The conversion operation removes partition entries for all partitions on the disk with the exception of the system and boot volumes for the current operating system.

Dynamic disks are not supported on portable computers or Microsoft Windows XP Home Edition.

Before you change a dynamic disk back to a basic disk, note that all existing volumes must be deleted from the disk before you can convert it back to a basic disk. If you want to keep your data, back up the data, or move your data to another volume.

How to Convert a Basic Disk to a Dynamic Disk.

To convert a basic disk to a dynamic disk:

1) Log on as Administrator or as a member of the Administrators group.

2. Click Start, and the click Control Panel.

3) Click Performance and Maintenance, click Administrative Tools, and the double-click Computer Management.

4) In the left pane, click Disk Management.

5) In the lower-right pane, right-click the basic disk that you want to convert, and the click Convert to Dynamic Disk.

NOTE: You must right-click the gray are that contains the disk title on the left side of the Details pane. For example, right-click Disk 0.

6) Select the check box that is next to the disk that you want to convert (if it is not already selected), and the click OK.

7) Click Details if you want to view the list of volumes in the disk.

8) Click Convert.

9) Click Yes when you are prompted to Convert, and the click OK.

Try deleting upper and lower filters in regedit (Registry Editor). See if this helps.

Also make sure that other USB devices can be read on your system.

Double check BIOS settings as well and try to reload default settings. (Make sure USB is on)

Reinstall software to use my 160GB freeAgent Go USB


Hi, I am assuming that you are referring to a USB based external hard drive called Free Agent, by Seagate I think.

Which operating system are you using ?

Windows XP has native support for USB, and it should automatically detect the hard drive when you plug it in.
It should NOT require any other software to access the drive.

if not:
1) Check that the HD is powered up
2) Try a different USB cable
3) Try a different USB socket

4) Make sure that the HARD drive is correctly formatted:
i.e. Assuming you are running Windows XP
(Vista should have similar facilities)

Goto to the Control Panel -->
Double click on Administrative Tools
Double click on Computer Management
Look down, under storage,
Click on "Disk Management"
Give it a couple seconds to search for drives,
and to populate the list ...

Check to see if the external disk appears in the list:
It should be partitioned with an EXTENDED partition,
containing a LOGICAL drive, and formatted with NTFS.

If necessary, partition and format the drive, assuming
you have not already done so, and the drive does not
contain any data.

If the drive did previously contain your data, you can
either loose the data and re-format it, or you can hire
a data recovery company to repair the damaged drive.
