No powe-up. Not good. Try it on another PC/laptop. There is no reset switch. I assume it's a USB drive? Could be aconnection in the enclosure that's come loose?

My desk top computers screen went black, can my data be save on the hard drive and how can i take it off


Not posting the model number of the Dell desktop computer, get's you generic information.

The model number can be found on the back of the computer, next to the Windows product key.

Moving on......


Suggest use an external enclosure.
Remove the harddrive from the computer, and install it in an external enclosure.

The external enclosure has a USB cable, and you just plug it into any available USB port, on a working computer.

Then go to My Computer, or Computer; depending on which Windows operating system the computer has; and double-click on the drive letter that corresponds with the external enclosure.

(WinXP: Start > My Computer
Win Visa / Win 7: Windows logo button > Computer )

Examples of drive letters;

C: Drive = Harddrive of the computer you are using

D: Drive = Separate partition on the harddrive for Restore files, or is for the optical drive (CD/DVD drive)

E: Drive = Optical drive generally, but may be the drive letter that corresponds to a Removable Device.
The external enclosure you plugged in, is a removable device.

None of the above is 'etched in stone', except the C:Drive
Things change from computer to computer, and the way you may have it set up.

Easy way to know?
Before plugging in external enclosure, open My Computer, or Computer.
Look at what each drive letter corresponds to.

Now when you plug the external enclosure in, you will see the change; and know which drive letter corresponds to the external enclosure you just plugged in.

Double-click on the name next to the drive letter, that corresponds to the external enclosure you plugged in.

Go into My Documents, or Documents.
Again, depends on which version of Windows you have.
Win XP = Start > My Documents
Win Vista / Win 7 = Windows logo button > Documents

Now open each folder, until you get the personal files you want to keep.
Photos, music, videos, documents you have created, or downloaded.

You cannot remove programs, or applications. Just your personal stuff.
(You can, but that is for a separate discussion)

Also open Downloads.
(WinXP = Click on Start > My Documents > DOUBLE-click on Downloads.

Win Vista / Win 7 = Click on the Windows logo button (Start), click on Documents, click on Downloads.

Harddrives are measured in Width.
2-1/2 inches across for a laptop harddrive. 2.5 inches.
3.5 inches for a desktop harddrive.

Don't know what Dell this is again, don't have the model number.

Cannot tell you if the harddrive is an IDE (PATA) unit, or a SATA unit.

So you will need either a 3.5 IDE (PATA) external enclosure,
OR,
a 3.5 SATA external enclosure.

There are external enclosures that are 3.5 and IDE/SATA, also.

Basic examples,

Easy way to identify what type technology is used, for the harddrive in your computer; IDE/PATA, or SATA;

I looking for a pcb boad for hd western digital


That would be on another WD2500JB Caviar harddrive

Either that, or start looking on the internet posting -
WD2500JB PCB Board, and see what search hits come up.

Here,.....let me try.............

http://www.hdd-parts.com/18100096.html

Before you replace it, let me ask........
1) Was it in a Desktop PC?

2) Was it in an external harddrive?

External harddrive?
Then suggest you obtain a 3.5 IDE (PATA) external enclosure,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3883498&CatId=2780

In an external harddrive there is a small interface circuit board.

The Harddrive plugs into the small interface circuit board, and the USB cable is attached to the small interface circuit board.

It is this small interface circuit board that usually goes bad.

The external enclosure is just like the case of the external harddrive.
Has a USB cable going to a small interface circuit board, and the harddrive plugs into it.

WD 500G HDD suddenly un-readable; changed name to local disk, says I need to format in order to use it. I have tons of important stuff on there.


Could you confirm if the problem with the drive not being recognized is a problem with the USB cable? I have a 250GB passport and it worked fine with my XP. Once I decided to reformat it to NTFS and tried to do so by plugging into my new windows7 laptop the problems started.

Can not get computer to recognize hard drive any more?


You could try using another USB port on your computer. Perhaps that USB port you have the IOmega external harddrive plugged into is bad.

More than likely not, though.

The problem is usually inside the IOmega's case. (External enclosure)

Inside that IOmega external harddrive's case is a regular harddrive as used in a desktop, or laptop computer.
To explain;

Harddrives are physically rated in width, as well as type, and size.
A laptop harddrive is 2.5 inches across in width. (2 and a half inches)
A desktop harddrive is 3.5 inches.

The larger desktop harddrives are usually used in external harddrives that are 500GB, and larger.
(Not always the case when it comes to the 500GB size)

Harddrives have two technologies, or types.
IDE (PATA) or SATA.

You didn't state the Model Number so I can't even hazard a guess at this point.

The harddrive inside the case plugs into an Interface.
The Interface may be separate, and connected via a cable to a small circuit board, or the Interface may be soldered directly to the small circuit board.

It is this Interface, and circuit board which go bad.
The solution is to remove the harddrive inside, purchase an inexpensive external enclosure, and install the harddrive into it.

The external enclosure has a USB cable just like the IOmega external harddrive did.

As stated the harddrive inside is just a normal harddrive. Made by a harddrive manufacturer.
Could be a Western Digital, or Seagate, or Hitachi, or Maxtor, or Fujitsu, or IBM, just to name a few.
(Seagate bought out Maxtor)

On the harddrive will be a decal with it's specifications.
You will also be able to physically measure the width.

This external hookup will support harddrives that are 2.5, or 3.5 inches in width, (And 5.25), plus will support both IDE (PATA) or SATA harddrives,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7220658&CatId=3770

This external enclosure is for a desktop sized harddrive, 3.5 inches, and will support either IDE (PATA) or SATA harddrives,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1951866&CatId=2780

This external enclosure example is for laptop sized harddrives, 2.5 inches, and will support either IDE, (PATA), or SATA harddrives,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7041055&CatId=2783

Just one example of how to disassemble an IOmega Select Portable harddrive,

http://www.youtube.com/watch?v=NvUvz5Qb4vw

Other styles are listed in the Suggestions column down on the right.
Not a good source for information on disassembling an IOmega external harddrive, but there is very little info available.

(It isn't that tough for any external harddrive enclosure. The screws are usually hidden under labels, and the case pops apart in two halves. Just a little different design here, and there)

My Lacie external hard drive used to turn on when the computer using XP was turned on. It has stopped doing this. Any suggestions to solve this?


if your computer came with a motherboard disc the drivers could be on it
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
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, sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
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 hope this helps

Having a similar problem with the La Cie 500gb. Powerbook G4.


The problem that has been inherent with all LaCie external harddrives, is the interface in the case itself.

Interface:
All external harddrives have a Style of harddrive that is used in a laptop, or one that is used in a desktop computer.
Laptop harddrives are 2-1/2 inches across in width.
Desktops are 3-1/2 inches across.
Your LaCie will have a 3.5, (3-1/2) inch desktop style harddrive, inside the case.

There are two main Types of harddrives.
IDE and SATA. (There is also a newcomer. SSD. SSD isn't being used in LaCie external harddrives at the moment, to my knowledge)

Your LaCie will use a SATA harddrive inside it.
This is an example of an average SATA harddrive,
http://en.wikipedia.org/wiki/File:Hdd.jpg
The photo of this harddrive is tilted at an angle, that doesn't readily show the interface connection, but it helps to explain.

At the bottom of this harddrive in the photo, and to the left, is the interface area.

Viewing the harddrive, look at the four metal pins on the extreme right of the harddrive. To the left of these pins is the Jumper pin area. (Has a white jumper on two of those pins)

To the left of the Jumper area is an opening, and to the left of that, is a long slot. The first small slot area is for the 7-pin Interface cable.
(Data cable) The next slot to the left, is for the 15-pin power cable.

This 7-pin Interface mates up to socket holes in a connector, of the case of the LaCie external harddrive.

It is this interface connector, inside the LaCie external harddrive case, that is the problem.
Solution?
Buy a quality, in-expensive External Enclosure, take the harddrive out of the LaCie, and install it in this enclosure.

Examples of 3.5 Sata External Enclosures,
http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=2780&name=3.5-eSATA-enclosure&Nav=|c:2778|&Sort=0&Recs=10
(From $15 to $35, is a good range for a decent external enclosure)
