SOURCE: wd mybook lights flash and cannot acess drive

Just an FYI for anyone else with a similar problem. I had my buddy look at it and it was discovered that the problem was with the power cord.
If your hard drive is still under warranty, call WD and ask that they send you a new power cord. It worked for me instantly.

Worth trying anyway,

SOURCE: Toshiba 160 GB Hard drive is not seen by 'new' computer

I have had a similar problems with external drives that only plug into a USB port (no ext power adapter). It is very common that the power supply fed through the USB port is inadequate to power an external hard drive. Some enclosures have a external A/C input to resolve this. Also, some computers (motherboards) only have a select number of USB ports that are powered. Since this device is detected by your other computer and not on the new one, my next attempt would be to locate a USB hub with external A/C power. There is a good chance that this will resolve the problem. By the way, when you plug in the drive does it spin up?

Remove and refit your hard drive. If that doesn't work, you may have a faulty drive. First look in the BIOS under Storage and see if the Drive is actually being seen by the computer. To check if it is the computer or the drive you should try a known working one to see if your drive is shot!

I have toshiba 250 gb HDDR250E03X i am unable to write a data of 4 gb or more(single file of 4 gb or more)..?

Hi this is a file system issue. It is probably formatted in fat32, which does not support files above 4 gigs.
To solve this problem you'll need to reformat it (my computer => right click on the drive => format), using ntfs file system (under file system select ntfs).
So back up everything before proceeding.
After it is done you will be able to copy files of any size onto it.

Alternative solution: download winrar and split your files into chunks smaller than 4 gigs.

Good luck!

click start control panel administrive tools ,computer management ,device manager look through all of your devices if you see a yellow question mark?or exclamation mark ! or red x
right click to reinstall drivers or
if you can see your usb but its not working
ports(com&lpt)right click update driver
sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again,
check the USB leads that attach to the motherboard usually red-white-green-black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems also make sure the computers Ram and Cmos battery are securely seated
hope this helps

I have just tried, for the first time, using my new 320GB Canvio. The white pilot light comes on, and I feel the disk spinning for a short time, but there is no operating software presented, and no file...

External harddrives do not come with an O/S. They are for external storage, beyond the master harddrive you have installed.

The master harddrive has the O/S.
The Platters are spinning because BIOS had a look to see what is on the Toshiba 320GB external harddrive.

[You press the Power On button. The first chipset to receive power is the BIOS chipset.
(Basic Input/Output System)

BIOS looks to see what devices are connected to the computer, does a Ram Memory count, turns the Processor on, then hands the computer over to the operating system.

BIOS finds THE harddrive with the O/S on it ]

When the Windows O/S (Operating System) is installed on a computer is assigns hash values to certain major hardware components in the computer.

A) Processor
B) Harddrive
C) Motherboard. (Motherboard chipsets and BIOS software on the BIOS chipset)
D) Graphics chip. (Whether it is Integrated Graphics, {OnBoard}, or a graphics card)

Change any two of these hardware components and Windows throws up a 'red flag'.
Microsoft's User License states, "One genuine copy of Windows per One computer"

If a hash value has changed, such as there are different hardware components, Windows 'feels' it is being stolen.

Why do you feel there should be an O/S already installed on the external harddrive?
Awaiting your reply please state in a Comment.

Why can't I access anything that was copied onto my Toshiba 500G external harddrive. The computer doesn't recognize the program that made any of it, even though it's the same computer.

It is very possible the voltage on your computer's USB port is not handling the load. I would buy a "powered" USB 2.0 hub, plug it into your computer's usb port and plug the harddrive into the powered hub.

Windows failed to load because a required file is missing or corrupt This is what it keeps saying.

This happens with Windows sometimes. One of the little 'Quirks', as it were.

Do you have the Restoration disk? These will be CD's, that Toshiba MAY have supplied with the computer.
(Should be one of the following:
1.Restore CD
2.Recovery CD
3.Reconfiguration CD
4.Configuration Builder CD, {CBCD}

I indicate May, because many computer manufacturer's had/have stopped supplying them. The trend as far as I can tell, is that they are now supplying them with laptop's, and desktop computers, again.

Their reasoning?
Cost, versus whether or not the user/owner of the computer, will actually use the Restoration disk.

Let's say it will cost 50 cents. (US), to produce this disk.
Now take that times 50,000 to 100,000 computers.

$25,000 to $50,000 dollars.

If the computer owner isn't going to use them, why supply them?
Sometimes, the computer owner is afraid to use the Restoration disk. Winds up taking it to a computer repair shop. That little disk stays right there, in the computer desk drawer.

Restoration is also put on a separate area of the harddrive. A separate partition on the harddrive.

Problem is when this form of Restoration is used, the computer is brought back to the way it was, when it came from the factory.

Back to Day 1.

This means all the programs, and applications the computer owner has physically installed on the computer, are GONE!
All the one's downloaded also.

All personal files are gone. Pictures, videos, music, and any documents the computer owner has put on, is GONE!

The computer goes back, (Restored), like it was when it came from the factory.

The Restoration disk has a Repair option. The necessary Windows files are repaired, and all personal documents, plus programs, and applications are saved.

Just the necessary Windows 32, files are repaired.

It could be a harddrive that is failing.

The way to get to the bottom of this, is to use the Restoration disk.
Or, completely wipe off all your personal data, and restore the computer back to Day 1

Which way would you like to proceed?

If you have the disk we can proceed from there. Or you may want to order them from Toshiba.

Dead USB external HDD. Disk spins, light is on, but no one is home.


it does sound like the Hard drive enclosures circuit board may be the problem, there are ways to get the data off that will void your warranty, or there are services you can send it to who will get your data back for you and then replace it.

Let me know what your preference is and I can assist you either way.

Start up

what a pity! if you Windows is really just had a corrupt system file that caused it, try boot with this CD to recover bad sectors: "HDD Regenerator 1.51". This is also available in Hiren's BootCD.
By the way, what Antivirus you are using on the laptop? The cause of this may due to a Virus wrote a startup system file entry into the registry but your Antivirus picked up the file and removed it however not the action. That's why a file is "missing" upon reboot.
What you can do lastly is to take the harddrive out, put it into a external harddrive case, backup all your data from another PC, and reinstall Windows on the laptop.
