I had the same problem with an MP3 player once. What causes it is the connection between the Pc and The ext Hdd. What you need to do is either find another plug for the hdd, dont replace the hardrive just the USb cable, or muck about with the cord untill your computer notices 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.

Ihave Simpledrive 500GB external hard drive but now all of a sudden my PC does not recognize it when I go to my computer and look for it


If you have a SimpleTech SimpleDrive connected to your computer and you're experiencing problems with the external hard drive, there may be several reasons why it's malfunctioning. Troubleshooting your computer can help rule out common problems and the possibility that the hard drive may be defective. If you recently purchased the device and suspect there is something wrong with it, return the defective drive to SimpleTech or the reseller for a replacement.

Incompatible USB Port Problems W 7 First, please disconnect all USB devices and then perform the following steps:


Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.


In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".


Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".



Then, restart your computer and Windows 7 will reinstall all USB controllers automatically. for XP or earlier click start right click on computer select properties device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X you will need to update/reinstall drivers right click to reinstall drivers if you can see your usb drive but its not working ports (com&lpt) right click update driver if this fails to fix the problem Check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts b> SimpleTech SimpleDrive plug and play options makes it easy for you to connect the device to your computer. But you may encounter problems if your computer's USB (Universal Serial Bus) ports are not compatible with the external hard drive. Make sure your ports are powerful enough to operate the drive. USB 2.0 ports are recommended, but if you're using an older computer with 1.0 ports, the hard drive will function much slower or you may receive an error message that the device is not compatible with your system. b> Missing External Drive Letter b> If you're unable to find the SimpleTech external hard drive's letter on your desktop after you have installed the drivers for the device, it's possible that the external drive may be assigned to another drive. Sometimes, the hard drive is assigned to a network drive and you may need to manually change the drive's letter in Disk Management. Enable Drive Letter View b> Click the "Start" button and choose "Control Panel" from the start menu. Click "Folder Options" and navigate to the "View" tab. Scroll down and place a mark next to "Show drive letters," then click "OK." b> Configuring Drive Manager b> Click the "Start" button to launch the start menu. Right-click "Computer" and choose "Manage" from the menu. Click "Storage" in the menu on the right side to extend the section. Click "Disk Management" under the "Storage" header. This will show you a list of drives and removable storage on your computer. It will also report the status of the drives, such as "Healthy." If the removable storage does not have a drive letter or has a drive letter in conflict with another drive, you can assign it a new letter. Right-click the icon of your removable storage drive and click "Change Drive Letter and Paths." Click the "Change" button, then choose a drive letter from the drop-down menu. Select a letter that is near to the end of the alphabet to prevent drive overlap issues. Click "OK" to allow the changes to take place. You should now see the removable storage listed with your other drives on the "My Computer" screen. SimpleTech SimpleDrive Incorrectly Formatted b> SimpleTech SimpleDrive is normally pre-formatted for Windows NTFS (New Technology File System), but Mac users may need to copy the backup software and reformat the external hard drive for FAT32 or Mac OS to be able to use the external drive. If the external hard drive is not formatted correctly for your system, it may not function or work properly. b> External Hard Drive Inaccessible b> If you receive an error message that says "Drive Inaccessible," the SimpleTech SimpleDrive may not be able to read the service area of the platter. If the external hard drive emits a loud or abnormal sound, this could mean the device is failing. Test the drive on another computer to see if it is working properly. Otherwise, the external hard drive's surface area may be damaged or corrupted. b> Replacing a Defective Hard Drive b> You can return a defective hard drive that is under warranty to SimpleTech. The manufacturer will exchange the device if the seal is not broken. But if you break or tear the seal on the case, any warranty claims will not be accepted and the device will be returned back to you. SimpleTech will only accept the device if you contracted a commercial data recovery company to retrieve critical data from the external hard drive and the seal needed to be broken. Before returning the defective drive, you will need to secure a RMA (Return Merchandise Authorization) approval number from SimpleTech and furnish any invoices or documentation regarding the data recovery company's services. Hope this helps.

Computer not recognizing external Hard Drive


Aren't usb drives fun? Anyway, there are a few points where this can break down. Your external drive is actually made up of a few parts. It has a normal hard drive, and either what is called a "SATA to USB Bridge" or a "IDE to USB Bridge". If it is a full desktop size hard drive, it will come with a power supply that you plug into the back of the drive. If you have a laptop hard drive it can be powered through the usb port.

When you plug it in, the computer should recognize that you plugged in a new device and show you a message saying found new hardware, found usb to ata bridge, found disk drive etc. in that order. If you get these messages and still no hard drive shows up in my computer, then you may need to assign a letter to the drive or even format it. Right click on the "My Computer" icon, then select "Manage". On the right hand side of the window that appeared, double click storage, then disk management. It should list all drives attached to the computer. Your TB drive should show up as a removable disk, and should already have a partition. If it does not have a partition, you will have to partition it. Just right click on the rectangular part (on the right side) and select format. If you cant format it, try right clicking on the left hand side, the square bit, and select initialize. Then format.

If you just need to set a drive letter, right click on the rectangular part and select 'change drive letters and paths"

Here are some other things that can go wrong:

Not enough power, the drive isn't getting enough power and cant mount. Try plugging in the power adapter that came with it or try a different usb port. If it came with one of those funny looking Y shaped usb cables, plug both ends into the computer, so that it can get enough power.

Bad hardware, either the hard drive or the bridge is bad.

Then you need to return it to the store you got it from. If that is not possible you may be able to pull the drive out of the enclosure and use it as an internal drive.

Bad USB ports.

This can be hardware or software. If other usb devices work fine then this is probably not the case.

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 )

400GB Freecom external hard drive stops functioning itself.


I assume you are running windows operating system. You need to uninstall all your usb devices. Go to computer manager/device manager and select all USB devices and unistall them. Go to the start menu, click on run type compmgmt.msc. Find all your USB devices on the right side. Follow the instructions for each device to uninstall them by double clicking and then select uninstall. once you uninstall, click on the icon to scan for hardware changes located on the sub menu. Your operating system should recognize new hardware or reboot and the operating system should install them automatically again. After you reboot, logon do not connect the harddrive until you are logged in completely. The operating system should recognize a new device and install it automatically. I hope it helps.

I cant get my computer to read my external drive


If your Operating System is Windows XP or Vista? Then disconnect the external hard drive and start the computer, and let windows load until at least a minute or two after your desktop appears then connect the External drive and open "My Computer" to see if the drive is shown there along with your internal Drive(s).
The above works to recognize lost external devices for me most of the time. Good luck.
