Ext. Hard drive no longer recognised by computer operating on XP
Just today I discovered that my Maxtor External Hard Drive (1TB) is no longer working. At first I thought the adapter was broken. The green light still turns on when usb cable is plugged but when ''my computer icon'' is clicked and opened, the drive does not appear.

Re: Ext. Hard drive no longer recognised by computer...
Your file system on the drive might be corrupt along with all the data on the drive. You can try to download data recovery software or try the drive on a different computer. I hope this helped solve your problem.

Pleaes open the Device Manager and right click on the Yellow exclamation mark. Now, click on update Driver and select Install from Advanced Location. Type the Location as C:\Windows\inf and click on Ok. The Driver should be installed now.
Here are a few things to try. If you have access to a secondary PC or laptop, try connecting your drive to it using a different USB cable. Also try unplugging your drive from the power outlet for a few seconds and then connecting it again. If it?s still not being recognized, Maxtor has a free utility called PowerMax (available at www.maxtor.com) that lets you run various tests on your drive till it identifies the problem. Good luck!
You will probably need to install the drivers that came with the drive for Windows to see it. Check out the instructions that came with the unit and it will walk you through installing drivers and connecting the drive to your computer.
You may want to open the drive and check the internal connections first to make sure none came loose after you have powered it down.
I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.
1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability
2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)
3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.
4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.
5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port
If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further USB flash drives can fail for no apparent reason. Sandisk Cruzers are especially bad for this.
USB hard drives should be treated with extreme care. this is a real hard drive and knocks and bumps can quite literally kill them.
If a drive is CLICKING after an accident there is a very strong possibility that it is dead or dying. This is known as the "click of death".
Go to add new hardware wizard. This may not come with a disk if you do have a disk it will ask you to put disk in. If you do not find it there go to the HCL directory of the western digital website for installation directions.
Right Click on My Computer, click on Manage, go to Disk Managment, if the drive is available you will see it there. Check to see if it has a drive letter assigned to it, if not right click on it and choose Change Drive letters. Make sure you are on the external drive though, you don't want to change your C drive accidentally. It should pop up in My Computer.
im going to assume your on XP for these instructions. other wise you still need to do the same thing.
right click the my computer desktop or the start menu. go down to properties. open the hardware tab. open the device manager. Scroll down to it, remove the driver, just delete the whole entry. unplug the hard drive, then plug it in again. See if that works.
