Question about Hard Drives

1 Answer

Can't find my harddrive

My external worked fine for about a year, but this past week, my powerbook no longer sees it. I've been using the firewire 800 connection and also tried the 400 connection, neither works. When I plug it in and turn it on, the lights still turn on. So it seems like the harddrive works and that it recognizes it is plugged in but my computer doesn't show it and I can't access files from it. Any advice would be greatly appreciated.

My external hd (fantom titanium) doesn't regularly open on my mac suddenly


Inside the case of that Fantom is a regular harddrive.

Also inside that outer case is a small circuit board, that either the harddrive plugs directly into it; or there is an interface block the harddrive plugs into, and there are wires from it, that connect to the small circuit board.

(The USB cable is connected to the small circuit board)

It is this small circuit board that usually goes bad.

My suggestion is to remove the harddrive inside, purchase an economical external enclosure, and install the harddrive in it.
Have your harddrive back, and be able to use it as an external harddrive again also.

The Harddrive Inside:
Harddrives are measured by their Width.
A laptop harddrive is 2.5 inches across in width. (2-1/2 inches)
A desktop harddrive is 3.5 inches.

The Fantom Titanium II 500GB's harddrive inside, is 3.5 inches,

Details > Physical Spec > Form Factor > 3.5

What I can't tell you is whether it is an IDE (PATA) harddrive, or a SATA harddrive.
However this external enclosure for 3.5 inch harddrives, is for both IDE, (PATA), and SATA harddrives,

[ You can also look at the label on the harddrive, and look up it's model number online, to see if it is IDE or SATA. Just type the model number in your search bar ]

Just want to include information on IDE (PATA), and SATA, in case you are interested,

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.

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,
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.
Buy a quality, in-expensive External Enclosure, take the harddrive out of the LaCie, and install it in this enclosure.

(From $15 to $35, is a good range for a decent external enclosure)

Maxtor 3200

Seagate troubleshooting Error Code 10, states that drive has failed. (Seagate bought out Maxtor)

Before you resign yourself to everything is lost on this harddrive, how about trying one more thing?

How about putting the harddrive inside in a new external enclosure, and see if it works? I suggest that perhaps the external enclosure it's in, is bad.
The harddrive inside is a 3.5 inch harddrive. Same width as used by a desktop computer. It is a Sata harddrive.

Here's an example of a 3.5 inch Sata, external enclosure,
Just pop the external enclosure open that holds it now, take it out, and install it into an external enclosure like the example above. Plug in the USB cable.

Don't know if this applies to your particular Maxtor Personal Storage 3200, but when I went to search for the type of harddrive it uses just now, I ran into thsi, and thought I would pass it along.

Acomdata external harddrive is not recognize on vista

I had a similar issue with windows 2008 and windows 7. the drive lost all its info and had to be reinitialized under both of those O.S.'s..
You can try that as long as it doesn't have any data you need.. Once you do that the drive will work and you can start using it. The file system under vista and above is slightly different than xp.

Worked fine on my macbook but not by my powerbook g4 or any other computer

I would suspect a corrupted catalog file, these are the map that a comupter uses to find its way around the drive, they are also the first casualty when a crash corrupts something. Disc warrior will write a new catalog and fix everything. PCs do not see discs formatted for macs.

Maxtor II external-Won't work on new MacBooks or MacMini's w/duo core CPU's. Junk.

Did you have to format the external drive when you set it up on your G4? You'll probably have to format the drive with the computer you want to use it with. I have seen external hard drives unusable until formatted.
I hope I'm wrong about this, and good luck.

LaCie 500 GB hard Drive - does not register on my desktop

if it is a USB (or you have low disc space), it does take longer to show up on desktop and patience is required... on my iBook it takes over a minute for my Brick to show up... Whether it is USB or firewire, do try another cord (I had similar problem with my lacie firewire external... I used a different firewire cord and all was fine. If you have tried these already, I hope you find the answer... good luck
