I have a Qmemory Hi-speed desktop drive, usb 2.0 external hard drive that will not power up. Is the drive damaged or does it need a new power cable?

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.

Hi Kathleen,
Depending on the extent of the damage it may be possible for your local PC store technician to repair the USB connector.
Take the drive to your local PC store and enquire about a repair and what the cost would be.
At the same time you can ask them what it will cost for a new external USB hard drive case. They can easily remove your hard drive from the damaged case and install it into a new case. This will most likely be cheaper than having the old one repaired, as a new case should only set you back $10 or $20.
Best wishes,
Graemevm

Hi wfowler05...
This is for an external hard drive, but the same applies to your MP3 player

The external storage device has several major components:

* USB cable

* external power-supply

* disk-drive inside the enclosure

* USB-to-disk-drive adapter inside the enclosure.

Try a different USB cable.
Try a different USB port on your computer.
Try a USB port on a different computer.

Take a multi-meter, and measure the output voltage/amperage of the power-supply,
and compare with the specifications on the label of the power-supply.

Open the enclosure, and remove the disk-drive, and attach it as a "slave" drive in a desktop computer, to see if bypassing the USB-to-disk-drive adapter bypasses the problem.

Look at the label on the disk-drive, for manufacturer, product-number, serial-number, and manufacture date. Access the manufacturer's web-site, and use "check warranty status" to see if the warranty still is valid. If so, the drive can be replaced, at minimal cost to you.

Buy a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Search online for a professional "data recovery service". For a significant fee, they can repair your disk-drive, just long-enough to copy your files to a new disk-drive.

Try connecting it to a different USB port on your computer.

Try connecting it to a different computer.

If the problem persists, either:

* the USB cable is damaged,

* inside the enclosure, the disk-drive is not functioning
(although the lamp indicates that it is getting electrical power)

* inside the enclosure, the USB-to-disk-drive adapter has failed.

If the warranty is still valid, Seagate will replace it, at no cost to you.

Or, open the enclosure, and remove the disk-drive, and temporarily connect it as a "slave" disk-drive in a desktop computer, to see if it is working at all.

Or, buy a new, compatible, disk-drive, and mount it into the enclosure, to make a "new" external disk-drive.

An I/O error indicates an issue with the device driver(s) that handle input/output processes such as copying files to/from hard drives, data in resident memory (RAM) waiting to be processed by the CPU or the controller chipset that handles the primary calls to/from the subsystems or a faulty hard drive.
Below are a few solutions that may help resolve the issue and allow you to transfer your files:
Before proceeding, you will need the following:
A. Computer B. External USB Hard Drive C. USB Cable D. RAM Module (Replacement, if necessary) E. Hard Drive (Replacement, if necessary) F. USB Hard Drive Enclosure (Replacement, if necessary) G. USB Cable (Replacement, if necessary)
Note: Solutions B/C apply only to Windows OS.
Solution A. Faulty USB Cable
1. Replace the USB cable. 2. Connect USB hard drive to the computer. 3. Attempt to copy a file from the drive. 4. If successful, copy additional files, as needed. If not successful, skip down to Solution B, step #1.

Solution B. Locked I/O Processes
1. Press and hold the power button on your desktop/laptop for about 10 seconds (or until the system has powered off completely). Then release the power button. 2. Make sure the USB drive is plugged in. 3. Wait another 10 seconds and press the button once again to power on the computer. 4. Once logged in, attempt to copy a single file from the drive 5. If successful, go to step #6. If not successful, skip down to Solution C, step #1. 6. Continue to copy files from the drive. Make sure to pay attention to what files (if any) prompt the I/O error message. If you receive an I/O error, skip down to Solution C, step #1.

Solution C. Motherboard Device Driver Installation/Update
1. Click on the "Start" menu and click on "Control Panel". 2. A new window will open, double-click on "System". 3. A new window will open, click on "Device Manager". 4. A new window will open, listed in the hierarchy are all the hardware components installed on the desktop/laptop. Look for any devices that display either a red "X", yellow "!" or yellow "?". These devices have either incorrect, incomplete or missing drivers/software and need to be installed, as they might be the root cause of the trouble. 5. If any of the above icons are present, perform a Windows Update by visiting the site below:
http://update.microsoft.com
Perform any updates available on the software and hardware side. 6. Restart your computer. 7. Follow Solution C, steps #1-4 to determine if any drivers still need updates. 8a. If updates are not needed, attempt to copy files from the hard drive. If successful, go to step #9. If not successful, skip down to Solution D, step #1. 8b. If updates are needed, you may need to visit the support site for your desktop/laptop's make/model and download any missing drivers. 9. Continue copying files, as needed.

Solution D. Faulty RAM
1. Power off the desktop/laptop and disconnect all cables. 2. Open the desktop/laptop. 3. Remove all the existing RAM. 4. Install the replacement RAM. 5. Power on the desktop/laptop. 6. Connect USB hard drive. 7. Test by copying some files from your hard drive. 8. If successful, close your desktop/laptop and continue copying files, as needed. If not successful, remove replacement RAM and reinstall previous RAM and skip down to Solution E, step #1.

Solution E. USB Hard Drive Case Faulty I/O Board
1. Power off computer/desktop and disconnect all cables. 2. Open your USB external case. 3. Remove your existing hard drive. 4. Install hard drive into replacement USB case. 5. Power on your computer. 6. Connect your USB external drive. 7. Copy files from your external USB hard drive. 8. If successful, continue to copy files, as needed. If not successful, skip down to Solution F, step #1.

F. Hard Drive Malfunction
1. Power off computer/desktop and disconnect all cables. 2. Open your USB external case. 3. Remove your existing hard drive. 4. Install replacement hard drive into USB case. 5. Power on your computer. 6. Connect your USB external drive. 7. Copy files from your external USB hard drive. 8. If successful, continue to copy files, as needed. If not successful, this could be an indiction of a much larger problem in the form of a Motherboard issue.
If the motherboard is malfunctioning, this is a sign of bigger things to come and will require a replacement board in order to correct.
In the event that the motherboard needs replacement, depending on the make/model of the desktop/laptop, the cost could range from $35-120 for 3rd-party boards or $85-300+ for consumer-level systems from manufacturers such as HP, Dell, etc. and $350-1000 from Apple.
If your desktop/laptop is still covered by the manufacturer's warranty or 3rd-party extended warranty, any hardware component that needs replacement should be covered at little to no out of pocket expense to the end-user. This also includes the external USB hard drive, as well.

I can think of 3 possible causes to your problem:

1. Faulty cable - try replacing the cable by borrowing a working cable from a friend. If this solves the problem then you need to buy a new cable

2. Lack of power - some USB drives especially those for high capacity drives require extra power aside from that provided by USB. If you do not have a separate power leading to your drive, check if there is a separate power slot and run a cable from it to your outlet/USB slot. Just make sure that the voltage levels are correct.

3. USB Slot - some laptops' USB slots do not produce power enough to drive a hard disk. Other devices may work (e.g. keyboards, mouse) but not hard drives. Try to use another slot in your laptop. If this works, remember to use the same slot next time.

Hope this helps.

if this drive has 2 usb cables you need to connect both. one is for power other is for data. it may be also drive physical damage.

here are several possibilities
Bad Cable - Well it is probably unlikely, but I would first try another USB cable just to make sure the cable is not damaged.
2. Power Supply - Try another power supply if you have or can borrow one
3. Controller Failed – The Controller inside it has failed.
4.Drive Failure – The Hard Disk inside has failed. Drives typically have an average 5 year lifespan, some last longer and some can fail much sooner. Unfortunately, you rarely have any warning, thus the need for backups.
