if you are having trouble
with your drivers here is a general look at
the drivers and how to update them if your computer came with
a motherboard disc the drivers could be on it click start control panel
administrive tools ,computer management ,device manager look through all
of your devices if you see a yellow question mark?or exclamation mark
! or red x right click to reinstall
drivers or if you can see your usb but
its not working ports(com&lpt)right
click update driver make sure the lead/s that
attach to this drive have a secure seating and are not bad/faulty the light on
only tells that its getting power it might not be getting enough power you
might test the lead/s or just replace the cable of
the hard disk, when you plugged the external disk drive you got that
windows could recognize the USB device change the cable everything should work
fine again, sometimes the wires inside the cable will be damaged due to bending
or stretching or placing heavy equipment upon the cable, 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 hope this helps
I would unplug the external drive then shut down your computer. Plug the drive in(be sure the USB port is in good working order.)Turn the computer on. If it does not recognize the drive search online for tech support for that particular drive. Install any drivers or software. Be sure to find out if the drive is compatible with your operating software. Make sure all connectors are seating firmly and correctly. Make sure that everything is plugged in where it should be plugged in.
I would be very concerned that the drive may be failing, and make copies of anything important. Is the external drive full? Go to My Computer and right click on your external drive and click on properties and it will tell how much is free and used. 90% is very full. Check all your hard drives while you are at it.
You should go to the website of your hard drive maker and download a diagnostic utility to check the health of your hard drive. It will be on the website under support. This must be run from bootable floppy, bootable usb, or bootable cd.
This generally means you have a hardware failure in the drive or enclosure. The simplest way to test which is to have a hardware tech move the drive into a new enclosure and see if it works.
This will void your warranty if you do it, so, if the drive is under warranty and there are no files you consider valuable on the drive, call the manufacturer for warranty support.
If you value the data more than the drive is worth then take it to your local hardware vendor and ask them to test the hard drive in a new enclosure. Good odds it will work this way but if not you may need the help of a data recovery specialist.
In North America I use Armor-IT, if you are in a different region and the new enclosure fails to garner results, comment back with your region(Country, State, City) and I will supply you with the closest reputable facility.
I have that problem similiar to yours. My simple tech stopped working for like two years so i decided to open up my simple tech and removed my HD away from the old enclosure so I can try building my own external hard drive for the first time. I bought another new 3.5 enclosure, IDE/ATA for the old HD. I put it in the new enclosure and it worked!
It's the only solution you can have. No need to retrieve data or re-format your HD. You can leave it the way you like...if you wanna reformat it...up to you.
Yes, you need a power supply. I have several USB peripherals that, in a similar way, APPEAR to be on when you plug them into USB. But that interface cannot supply enough power to actually run the machine. The maximum is 0.5 A * 5 V = 2.5 W. The wee portable drives can run on that power, but a normal desktop drive, such as is inside a full-size desktop external enclosure, use ~ 8 W.
So you need a DC power supply! I bet SimpleTech can tell you what the correct current, voltage, and polarity is. Good luck.
