I tried to plug in my simpletech ext hard drive 320 g into my brand new laptop and the computer doesnt recogonize the hard drive at all. took it all to best buy geek squad and they told me I needed to dwnld a simpletech driver from the internet. Have been searching and the simpletech website doesnt have a driver for my 320g version, please help! I need to transfer all my files that I have saved on my ext hard drive

The drive has failed, sorry.

power source jack/plug might be the problem if it has been bumped about or if it was powered up and running before plugging in to the comp.....
i had the problem of my 1tb ext/hdd no longer being recognized because when i plugged it into my comp, the jack was live and not switched of at the wall. the only way i got it to work was to pull it out of the casing and switched it with the 320 ext/hdd i have as they are they same brand..just diff sizes. going to put the 320 into comp to become master drive as the internal is a measly 40g. i think i had burned out the connector pins on the power jack when it was plugged in live. i hope this is an idea for you to try.

Although I have seen it fail often, in your case it is worthwhile to try the 'Add hardware' wizard in the Control Panel. If you have an installation disk of any kind, have it at hand. Let the system look for the drive (plugged in of course) and if it finds it and has no drivers for it, it will ask for the installation disk but you may have to tell Win where to look for it by drive letter. If you don't have an installation disk, you will have to go through the drivers list offered to see if SimpleTech is listed.
SimpleTech still has an active website so I would check there first:
SimpleTech support page
If you have no luck you find no driver, there are several websites that have a huge array of drivers for current and obsolete hardware.
Good luck- 

I had the same type of problem and found when I took the cover off that the harddrive worked loose from the plug. Pushed back into socket and reassembled, works great.

check the power for the drive and also try changing the cable.
does the system display that usb device not recognised if it doesnt then the problem is with the wire.

This may or may not help, but it worked for me! After about 4 hours of trying everything (Device Manager/Uninstall, Disk Management, etc..) nothing at all would work. The USB external hard drive would power up but when you plug it in, the New Found Hardware will pop up and search unsuccessfully for drivers for a PLUG AND PLAY external drive!?!?!

In any event, I simply plugged another USB drive into my laptop (and desktop) and viola! The new hard drive was recognized and installed immediately as 'plug and play' should do. I then unplugged the new drive and tried plugging in the one that was recognized and all of the sudden....IT WORKS AGAIN!!!!

This fix might not help anyone who doesn't have a second USB external drive, but you could try plugging another USB device in and get it to load and then unplug it and try your drive. It worked for me on my laptop and then I did the same thing to my desktop (which also wouldn't recognize it) and it worked on the desktop too! Problem solved for me, thank GOD!

Hopefully, this bypass can save you a few hours of google time and unwanted anguish. Like I said, you may not have another USB drive but try plugging in any other USB device until it loads and then unplug it and then plug in your USB drive that wasn't working. It worked perfectly for me.

Hope it helps!!!!

I've had this problem before.

I tried a different cord and it started working again. Additionally i've had this work for me (see below)

Try This:

1. Unplug all USB devices
2. Turn off Ext Hard drive
3. Shut down computer
4. Power on ext hard drive (then wait like 1 min)
5. Turn on computer
6. Wait for windows to finish loading
7. Plug in the USB cord from the ext hard drive to your computer (may take up to a minute for computer to recognize it)
8. If it doesn't recognize it then keep trying it in different USB ports

If it still won't recognize get all the latest windows update and reboot. If that doesn't solve your issue try your external hard drive on some other computers, check to see if drive needs special drivers installed (which most don't).

From SimpleTech's website: "1) I have the drive plugged in but I cannot find the drive in "My Computer", why?
The most likely cause would be not enough power provided by a single USB port on your computer. Unplug the portable drive from the cable and unplug the cable from the computer. Now, plug the cable into 2 USB ports directly on your computer. (If you have a desktop, you should plug the USB cable directly into the USB ports on the back of the computer. If this is a laptop, you should plug directly into a USB ports on the computer. Do not plug into a USB hub or docking station). Then plug the drive into the cable. In a few seconds you should see the drive listed in the "My Computer" window as a SimpleDrivePS."

If all that fails you need to RMA (Return to Manufacturer) your external hard drive. Most hard drives have a pretty decent warranty on them. Your simpletech 250GB has a 3 year warranty on it. Info on the warranty can be found at http://www.simpletech.com/support/warranty/. If you want to RMA it, click the "Technical Support / RMA Request" on the left hand side of that page.

if you are running windows, then check the following:

go to control panel -> administrative tools -> computer management -> storage -> disk management.

you probably have a drive (located on the bottom right) that is listed with no drive letter, just assign it a drive letter and see if it comes back, if not, the drive is probably not initializing and you might have to either format it or replace it.

i doubt you can do anything about it. Code 10 is a hardware failure, so you will have to return it and get your warrenty.

If you are having issues accessing the drive i've encountered that situation before
