SOURCE: power cord buzzes and MACPro does not recognize it

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.

SOURCE: The power supply is green until connected to the

I devised these simple steps that tend to remedy quite a few issues with most portable / external hard drives (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability
2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)
3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.
4. Use ONLY the power supply that came with it if it has an external power supply
Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.
5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again.
If you checked and fixed anything there and still have issues carry on reading.
Go to your control panel and then administrative tools, select Computer Management.
Now select Disk Management and expand the window.
Your drive should be listed here, if not then you need to check your computer hardware has not got any issues before proceeding.
If your drive is listed and says healthy then right click on it an select Properties, click Tools and then Error Checking, Check now, tick the two boxes and then Start.
This will attempt to fix most minor / common errors on the drive. It may also ask you to restart which is fine. Allow it to finish its work or you could corrupt the drive. If all went well you should be able to use it normally again.
If you drive was listed but did NOT say healthy then right click and select Format. Choose NTFS as the file system and do not tick any boxes you do NOT want quick format. Again start and let it do its thing. When it is done restart your computer and you should be good to go.
If you still have problems with the drive you might want to look at other areas.

Just take the hard drive out the caddy and use it in another caddy. It will be easier and cheaper than fixing the caddy.

check usb leads for secure dust free seating

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

My Mac suddenly cannot find my Lacie external storage device. I have turned off, unplugged, restarted... etc. and it is still not finding it. The Lacie seems to be on, at least the blue light is...


A continuous flashing light on a Lacie drive is a notification of a problem. I do wonder if the light is flashing the same if the drive is plugged in to the Mac or unplugged.

Lacie external drives tend to have power-supplies which become weak/bad. Most users replace the supply and it will work again for awhile until the supply dies again. Try bringing the drive to a retail dealer with Lacie drives -ask them if you can just test your drive with another power-supply (if you do not have another). You can also try calling Lacie, it's always slightly possible they will be aware of this problem.

Alternately, IF the light is only flashing when the drive is plugged-in to the computer, try using a different USB or Firewire cable.

If the green light on your LaCie power supply does not light, you likely have a bad power supply. You can buy a new one from LaCie. If you are purchasing a new power supply from LaCie ask for the higher wattage unit. LaCie upgraded this a while back.
