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
Andrea

Click Start, Run and enter DISKMGMT.MSC Locate the drive in question and
ensure that its assigned a drive letter. If not, you'll need to manually

Simple Tech HD failing- takes 4 hours to tranfer 512 MB!?


Not exactly a solution but I have had the same problem with one of these Simple Tech Signature Mini 320's for a while. Real finicky. Will only be recognized on direct connected to MB USB ports and even then with Win 7 or XP I get the "This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port." no matter what ports I connect it to. While having this issue on this "main" computer I have previously connected it to some other computer (don't remember which, now) and it connected at 2.0 speed. What's going on??

I have a Acom data hard drive Model HD500uhe5-72


Here's what you need to do:

1. Try connecting the HD (hard drive) into different USB ports of the computer.

2. Try another computer to see if the HD would be detected.

3. Try another USB cable.

Do you hear a clicking sound on the HD itself while it's turned on? Check the Disk Management of your Vista computer to see if the HD would be detected under the Disk Management. Please follow the steps below:

1. On your Desktop screen, right-click the "Computer" icon > select "Manage".

2. Double-click on "Disk Management"

3. Connect the HD while looking at the Disk Management. If the drive letter appear then, it's your Acomdata HD.

4. Check the status if it's healthy or unallocated disk space. If it appeared to be unallocated, you need to reformat the HD to make it work again.

To reformat it, just right-click on the drive letter that would appear and there's an option to reformat.

NOTE: Formatting a HD would erase all the data saved in it.

Have a great day!

Pc doesnt detect/read portable HDD, but a USB connection appears on the task bar


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 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 especialy 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

Mac OS X 10.4.11 SimpleDrive 1TB HD appears on Desktop only occasionally. Does not appear in Disk Utility. Have transferred files to it, light is on, plugged in, just takes several restarts to appear.


If you unplug the power and USB cables from the drive (but not the computer), plug in the power and then plug in the drive, the Mac will remount the drive on the desktop. I am having the same issue, only my old HDD used to be my TimeMachine drive and now I want my SimpleTech drive for that. The issue is that when the SimpleTech drive disappears, OS X automatically uses my old HDD for TimeMachine and all my disk space vanishes.

Very ARRGH!!!

I'm trying to find a better solution, because having to mess with the cables means it's no good for TimeMachine... and very frustrating on top of it.

If you checked and fixed anything there and still have issues carry on reading.
Go to your control panel and then administrative tools, select Computer Management.
Now select Disk Management and expand the window.
Your drive should be listed here, if not then you need to check your computer hardware has not got any issues before proceeding.
If your drive is listed and says healthy then right click on it an select Properties, click Tools and then Error Checking, Check now, tick the two boxes and then Start.
This will attempt to fix most minor / common errors on the drive. It may also ask you to restart which is fine. Allow it to finish its work or you could corrupt the drive. If all went well you should be able to use it normally again.
If you drive was listed but did NOT say healthy then right click and select Format. Choose NTFS as the file system and do not tick any boxes you do NOT want quick format. Again start and let it do its thing. When it is done restart your computer and you should be good to go.
If you still have problems with the drive you might want to look at other areas.

NOT WORKING OF 120GB PORTABLE HARDDRIVE


I think you are using an 2.5" notebook hard disk drive into this external case which hasn't got an extra power supply.

Since you're using an USB1.1 connection this could be a USB1.1 issue, USB2 returns more power to the connected device, since you connected you harddrive too an USB1.1 port you might need an USB cable which you can plug into 2 USB ports.

By doing this one USB port will provide the power to spin the drive up (which needs a lot of power) and the other cable will be able to focus on the data transfer.

You can also check your disk manager, it could be the drive is requesting a drive letter that's aready in use by another device. Go to start -> right mouse click on My Computer -> manage -> storage -> disk management. If the device is within this list you might attach another drive letter to it by doing the following. Right mouse click on the disk -> Change drive letter and paths and there you change the current drive letter into another one.
