The drive was left on for an extended period of time and may have overheated.

When the drive letter is clicked, the response states that I need to format the disk.

The drive now makes a noise as if it is spinning but the noise is louder than the noise made by an identical drive that I also own.

XP and Vista cannot read any information on the drive.

The drive cannot be read so that a Windows diskcheck cannot be performed.

Properties of the drive show 0 free space and 0 used space

I tried an alternative power supply from an identical drive – no success

I tried an alternative USB wire from an identical drive – no success

Using a forensic tool I acquired an image of the device that shows the following

Type of file: DD File
Size 4,194,300 KB

The forensics tool provides the following report about the drive:

    Whenever I try to open a file from my hard drive, it disconnects after a few seconds, but then it comes right back. I tried to move all of my files from my external hard drive to my PC but it disconnects after a few seconds again. What do I do? I bought it 9 months ago!

It has to do with the way computers count. Computers count in binary where we count in decimal.
Hard drive makers list there drives capacities in the decimal format, where windows lists it in it's binary format.
Wikipedia has a good explanation.

Also, the drive may have some preinstalled software on it that could be taking up a bit of space (it's usually not much).

SimpleTech has problems with their controller board. The HDD inside probably still works fine. You might want to get an external chassis and take the hard drive from the SimpleTech and put it into the external chassis. You will need a sata one.

SOURCE: SimpleTech SimpleDrive Pininfarina 320GB Power up problem

It could be that it's internal power supply burnt out,
in which case the drive itself could still be fine.

Try opening up the external case, and removing the drive.
Once you do, plug it in to your computer directly using its SATA cables, and see if that works.

Hope I helped,

SOURCE: SimpleDrive 160 GB drive is recognized by XP, but

The drive was damaged during the interuption. This has happened to alot of my flash drives and there is not way to fix it. You can, however, replace the hard drive in the case. Open the case and you will see a small laptop hard drive (that's all it is), purchase a new replacement and throw it in there.

I seriously doubt the integrity of this question as any forensics Dept would know how to do this.

There are plenty of data recovery programs on the net that will do the job.

SOURCE: My SimpleTech Hard Drive has stopped working

Okay , so there are some steps to figure out what is wrong with your external.

Firstly , if your computer makes a sound when you plug in your external , go to Start-Control Panel-Administrative Tools-Computer Management-Disk Management , and see if your external drive is listed here with your local drives. If it is listed , right click on the drive and change the drive letter to make it appear in "my computer".

If your drive does not make a connection sound when connecting to your computer and also does not show up , please follow the next step.

Remove the hard drive from the casing if possible and install it in your computer case or another external case.If the drive works , the problem is with the casing and you can ignore the drive.

Now , if the problem is with the casing , there are still 3 possibilities.

  1. The USB cable between the drive and the computer may be damaged.
  2. The circuit board which connects your drive to the interface of the external may be blown.
  3. The power supply (if applicable) may have a blown transformer.
The latter is the easiest to diagnose , does your external light up at all when you plug in the power? If not , then this is probably your problem. On the bottom of the adapter is a label which you will be able to use to have a new adapter made at your local electronics shop and this will cost about $30 max. They will also be able to test the adapter with a clamp meter to see if this is really the problem and this should be free.

The second component you want to test is the USB cable. If you have a printer , swop out the cables and see if your printer functions normally. Most externals use the same connector so you should be able to test it in this manner. If the cable works go on to the last step. If the cable is defective , replace it with a new one which you can find for about $10 at most electronics and chain stores.

The last component to test is the circuit board. This is a bit of a grey zone as you probably won't be able to spot the blown component unless it failed really badly. With the casing already opened , locate the external's circuit board and check to see if you have any blackened components or fluids leaking from some components. If all the other components of the external worked perfectly , then this is the faulty part. It is not really economical to replace the circuit as most of the time it is out of production by the time you need to replace it and it still costs a lot even if it is available so if your drive is working perfectly when connected via sata or IDE on your computer , the best is to buy a new casing and place your old drive in the new casing.

A casing costs about $50 and you could get it at most tech shops and big chain stores like Best Buy.

I hope this solves your problem and please reply if you need more help.

Kind Regards

How can I get a replacement power supply?

What you are after is an AC adapter this model I found on ebay has 120 volts to 240 volts to 12 volts make sure the DC voltage output matches the Voltage of your hard drive. The current output has to be the same amount or larger in value. So if your drive needs 2A a 2A or larger value means it can handle the current load put on it by the Hard drive.

this one below matches the exact model number of your hard drive
