Question about LaCie Computers & Internet
Lacie 500gb firewire will not show up on my macbook or macpro. It starts spinning when connected but will not show up on desktop. I have switched out firewire cables and tried the USB. It will show up in disk utility repair but will not fix as it states that it is not mounted.
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

I am sad to say that it's probable that this drive has failed. But if there is critical information on it, please unplug and discontinue use immediately.
You do stand a chance of recovering data if the drive has failed, but you lessen those chances as you continue to try to use it.
Definitely take this drive to a qualified repair outlet who can help with data recover if you need the information off of the drive.

This is a fault in the power supply itself, I have just repaired one of these power supplies successfully.
The fault is caused by the failure of the filter capacitors on the 12V supply rail, and if the power supply is left connected to the mains supply (In our case 240V 50Hz) without the drive connected as a load, the unloaded output voltage will exceed the voltage rating of the capacitors, causing their failure. The failed capacitors had very obvious bulges at the top, and one was beginning to leak onto the PCB.
The filter capacitors on the 12V supply rail are rated at 16V, and the cpacitors on the 5V rail are rated at 10V, and when operated without a load, the 12V rail rises to approximately 19V, and the 5V rail rises to approximately 8V. All output filter capacitors are 1000uF, and 105deg C temperature rated.
I repaired my power supply by replacing all of the filter capacitors on the DC low voltage output rails with 1000uF 25V capacitors. Be careful to only fit the 105 deg C rated caps, as they operate at elevated temperatures in an enclosed environment with no ventillation to cool the power supply.
To ensure that the repair was reliable, I also replaced the filter capacitor on the 5V rail with the same 1000uF 25V, even though that capacitor showed no immediate signs of failure.
When reassembling the power supply, care must be taken to ensure that parts like the ferrite cored transformer are thermally bonded to the aluminium heatsink with a smear of heatsink compound.
When the power supply was first powered up following repair, everything was normal, the green power LED came on as usual, the supply outputs both came up OK, and the unit was not making any buzzing sounds, completely silent. The HDD now operated as normal when once again powered from this power supply.
This was the fix for my particular LaCie power supply model ACU057A-0512, and the supply once again works normally.

If you can hear clicking then I am afraid there is a serious problem with the hard drive.
The noise you can hear is usually known as "the click of death" when referring to hard drives.
Make sure you use ONLY the cable that came with it or a SHORTER one.
Dont connect via a USB hub
Make sure you only user the power supply that CAME WITH IT.
Most common causes are that the drive unit was dropped or mishandled or just plain old age
There is no known cure unless the data is mission critical
In which case you could sent it to a data recovery specialist but this is usually VERY expensive.
If you are advised to place it in a freezer or anything similar then that is up to you
but my advise would be to run from the person who may give this advise.
This is very old fashioned advice and meant for very old types of drives that used to get very hot.
If it a drive that was / is from an external enclosure then you could still use the enclosure and just place a new hard drive in there.
Another way to test it it to remove it from the enclosure and connect it directly to a PC with a suitable interface eg. SATA or IDE.
