Toshiba external hdd not recognised by any computer i try

Toshiba 350 gig external hdd not recognised by any computer i try it on and is making a soft, repeated double clicking noise. the power light is on and i have tried a new usb cable without success.For a couple of weeks previously the hard drive worked but took an age to get to auto-play. Now it has stopped being recognised altogether. I have checked the usb ports on the computers i have tried it on and these have all worked with other devices. I can only think that the problem is with the box itself.

Hi there, I have a Toshiba external HDD 250GB that is giving me some problems and need some urgent help! When I plug my external HDD into my laptop everything seems to work fine. The lights come on, the...


It sounds as though your issue is one of in adequate power. Do both the external HDD have their own power source, or are they powered through USB? if they are powered through USB it may be that as soon as the second drive spins up to transfer the files, it overwhelms the limited power of the laptop. You can try it with the laptop plugged in (though this may not provide it with more power than the battery) or by purchasing a usb hub with its own external power source so that it is not drawing power from the laptop, or purchase an external hard drive with its own power source
The other option is simpler and free, and its to copy the files first to your laptops own HDD, then unplug the source external hard drive, and then plug in the drive you want to copy to, then transfer the files from your laptops hard drive. This will of course take twice as long, but will cost you nothing.

Formatting an external hard drive


Open up Folder Options\View\Show Hidden Files and Folders. Return to your Toshiba HDD. Do you see an hidden files? If so, try to delete them. You may have to change the Properties of these Folders\Files in order to delete them. BE WARNED, removing or deleting any folders or files that Toshiba placed in there could have negative affects on the way your external HDD runs.

Your OS is not booting. There may be few reasons.
1) Your hard disk is damaged and your BIOS does not recognise your HDD. Goto BIOS setup and see whether your HDD is shown. If it does not appear there, you may have to replace the Hard Disk.
2) Your HDD is recognised by the BIOS but Master Boot Record (MBR) is missing or damaged. Try booting from an XP CD. See whether Windows Setup detects your HDD. If the setup says there is an existing installation, try repairing it. After repairing, reboot and see whether you can use the computer. Otherwise make a new installation.

Hard drive not showing in bios


It appears that your #2 hard disk has died. To test if it is faulty, remove the #2 drive and connect it to an USB hard drive adapter and plug it into the USB port of a working computer. If the computer see it as an external USB drive and you can see the folders and open the files, then it is OK and the fault is possible the disk controller.
If the hard drive is not recognised then it is faulty and needs to be replaced.

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

Size of HDD for Compaq Evo300 Desktop


HI,
This depends on what the Bios recognises.
And which Types of Drive IDE Or SATA.
Depending on the setup, and whats already in there, you could Go 80-100 Gig Comfortably. Or use an external hard-drive, if more space is required.
