I have my simpletech in 2008, when I plug it then there is red and blue light. once the blue light is on I can access my data. I had vista before. from the time I have upgraded my computer into windows 7 I can not access my ext drive simpletech anymore. I have now windows 7, 64 bits

Try Geek Squad or a computer store that can do hard drive recovery.

Take out the hard disk from your case and put it inside a desktop- if there's still some life left in it it will appear in My Computer. If it doesn't appears even there then it's dead for sure and all the data on it is lost.

Hi,

You usually get this cable from nearest Bestbuy, Staples or Walmart store.
You can take the SimpleTech SimpleDrive to the store and ask for the adapter and they should be able to supply it.

This way you wont have trouble of getting you wrong part shipped as well.

Thank you for contacting FixYa

do you connect the both usb`s plugs?

AFTER THE BLUE LIGHT GOES OFF A RED LIGHT GOES ON

The red light is an indicator of drive failure. The fall it took, especially if the drive was on at the time, could easily cause the drive to break something internally so that it will not function. I found SimpleTech drives to fail pretty easily, even when you're not dropping them. That's been my experience, anyway.

Data recovery is a very expensive proposition. If the hard drive doesn't respond to the interface as normal, they have to be pulled apart and data extracted from the internal platters. This isn't something you can do without a full safe room (dust-free, wearing special suits and all) because any dust can ruin the platter. Since it's so involved, it's usually really, really expensive. Generally, most people don't bother when it reaches that point unless it's business files (like all of your financial data, for instance).

However, if it's something you really need that bad, DriveSavers is one of the best:

Right click on MY COMPUTER and select MANAGE.

Go to DEVICE MANAGER and expand the DISK DRIVES category on the right side window.

You should see the Simpletech drive listed under there. Delete the Simpletech drive and click on OK. Restart the computer.

Windows should re-detect the simpletech and re-install the built in drivers automatically.

Yes you should. 

do you mean that you used this as a "Data" drive and do not have the data stored on your pc...

that is basically the same as having no backup... if it is important, store the data in more than one location.

it is possible that a power surge killed the usb adapter on your storage device.... you may be able to transplant the HDD onto a working adapter or USB->HDD bridge to get your data back
