Question about LaCie 500GB USB 2.0 7200 RPM 8MB 500 GB Hard Drive

2 Answers

External hard drive read only on my mac?

I have been using my LaCie External Harddrive as my backup since last November, and is working fine until now. The harddrive has all of a sudden become read-only even though I am the only user of the computer. I can view all the files in the drive, I just can't write and back up my computer.
Any help would be much appreciated!

That's a very strange occurrence, I agree with you. The good news is that one of the standard administrative applications included with Mac OS X will doubtless fix what's happened on your disk, which is that a folder permission has somehow been messed up.
The program you need is Disk Utility and you can find it in Applications --> Utilities --> Disk Utility. Then simply select the drive you want to fix:

Lacie External Drive won't turn on (blue Light doesn't go on)


Inside the LaCie D2 250GB (300770) external harddrive's case, is a 250GB IDE (PATA) harddrive that is 3.5 inches across in width.

A desktop computer sized harddrive. (May be a Western Digital WD25000JB)

The harddrive plugs into a small circuit board, (Bridge board), and the circuit board has a USB port on it.

Using this Western Digital Passport for an example,

http://www.xbitlabs.com/misc/picture/?src=/images/storage/wd-passport-250gb/p3.jpg&1=1

Scroll down to the second photo, and left-click on it. The case of the external harddrive is shown open.
Inside is a 2.5 inch laptop sized harddrive.
An aluminum tape strip covers the small circuit board, attached at the back of the harddrive.

The second photo down on this page, shows you the small interface circuit board, that the harddrive plugs into, with the aluminum tape removed.

http://www.xbitlabs.com/articles/storage/display/wd-passport-250gb_2.html

(Another design has wires coming from the small circuit board, to an interface the harddrive plugs into )

It is this small circuit board that goes bad in a LaCie. QUITE common.

Solution?

Simple.
1) Obtain a 3.5 inch IDE external enclosure
2) Remove the 3.5 IDE harddrive from the LaCie's case.
3) Install the harddrive out of the LaCie into the external 3.5 IDE enclosure.

An example of a 3.5 IDE (PATA) external enclosure,

My Lacie 500gb external hard disk has stopped working. it has a scratching like sound and no computer couldn't detect it. even it is not detected in device manager. when it is connected to computers it...


is the scratchy sound coming from inside your lacie or outside ??

it might be a power problem trying to connect to your lacie but unable to find the device or a dirty hard drive the reader arm skipping across the platters you could give your lacie a firm tap on the side to free up the reader arm

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
if this fails to fix the problem

you might have to install a usb 2 or 3 card they are cheap and easy to install you can buy these on Ebay very cheap
hope this helps

My lacie drive fell off desktop and is not recognized as readable by my Mac. What chance do I have of recovering the data?


Inside that LaCie external harddrive's enclosure is a regular SATA harddrive.
The kind that fits in a desktop computer (3.5 inches in width), or laptop. (2.5 inches across in width)

Open the external enclosure (Case) of the LaCie, remove the harddrive, and install it into a suitable external enclosure.
(Laptop size, or desktop size)

The external enclosure has a USB cable also. Just plug it into any available USB port on your desktop computer.

Do I know for a fact that the harddrive is okay, and this will fix the problem?
No sir/maam I do not.

But IMHO this is the first diagnostic method to use.

IF the harddrive is a desktop sized harddrive, it could be installed in your desktop computer as a Slave drive.
However the above method is so much easier, and it allows your harddrive to be an external harddrive once more.

Inside the external enclosure of the LaCie external harddrive, is a small circuit board that the Harddrive plugs into.
It is this small circuit board that receives the damage in most cases.

If the problem is the Harddrive itself, a professional data recovery shop will;

A) Try a new, or good used harddrive circuit board.
Check to see if the harddrive's circuit board received the damage.

B) If the circuit board proves to be good then the next step is to remove the Platters inside.
The room used is a Clean Room.
A room that is 99.9 percent dust free. (In most cases)

The Platters are installed into the case of a compatible harddrive, that has the Platters removed.
Then as much information as possible is copied off.

There are other methods data recovery specialists use also.

[A Harddrive is built in a Clean Room. 99.9 percent dust free. The technicians wear a Clean Suit, that resembles what a doctor would wear in an operating room.
They enter the work area after going through a corridor, fitted with air jets at various levels.

If a harddrive is opened up in a room that is not a Clean Room, the harddrive's 'life expectency' drops to a day, or a few hours. The dust 'kills' them ]

Observe the other videos also.

Examples of both a SATA 2.5 external enclosure, and a SATA 3.5 SATA enclosure,
(The Harddrive's width is measured in inches. (2-1/2 inches for a laptop drive, 3-1/2 inches for a desktop drive)

The icon for my lacie exyernal hard does not show


Here's two suggestions. (If your using Mac OS X 10.x)
Make sure external hard drives are to be shown by clicking "Finder" in the menu bar then "Preferences" and under the "Sidebar" section selecting "External Disks".
Also check that the hard drive is mounting by opening "Disk Utility" by first opening the "Applications" folder then the "Utilities" folder and double clicking "Disk Utility" and in the left sidebar checking to see if your external hard drive is listed as one of the mounted drives. Hope this helps, don't forget to comment/vote if this helped. Thank you.

Will erasing my LaCie ext HD impact any files on my Mac Book?


It will only effect thoes stores on the external harddrive. You will have to check the contents of the LaCie drive and see if it has any files you typically access from your Mac Book. Other then that no it will not effect files stored on your Mac Books drive.

Bob,
I had a similar problem with two LaCie external hard drives.
LaCie doesn't manufacture hard drives, they only purchase drives from other companies, like Seagate, and mount those drives in LaCie external enclosures.
If the drive is nearing the point of total failure, then your Mac is letting you know that point is very close. You had better find a new backup device to use. The Mac will let you access the drive for a while longer, but if you do not act, there will come a point when the Mac will not be able to read the data on the drive and any backups you have there will be lost.
When you get a new external hard drive to use for backup, you may not need to do anything with the current drive that is failing, as long as you do not anticipate that you will need anything from the backups that it contains. You can set up the new device as your primary backup. I would then advise that you perform a total backup on the new device ASAP, so that you are not left without at least one good backup.
