I have a Lacie 1TB Big Disk Extreme. It has recently developed a loud regular whirring noise, that goes on and off every few seconds. What should I do? Thanks! Adrian

Hello,
the first step will be to verify your power supply. When it is plugged to the wall power outlet, it should be silent (no hissing or high pitch noise) and the green light should be on on the power supply.. If it is not the case, replacing it might solve your problems.
Second step is to verify if it is an interface problem. Try using a different port on the drive.
If no success, start Disk Utility and look to the left if you have any mention of a drive of 1TB. If you do, the partition of your drive might be corrupted. You can try running First Aid from Disk utility if its available, else you will need to try a partition repair software or a Data recovery program.
There are a few available that you can get a free copy to see if the data is available before you buy.
Regards,

I have the same problem too on my 2big form lacie . If I use 2x 1,5 tera disk in "fast mode" or in "big mode" my disk manager only shows 746 gigs available (it should be at least 2,5 terra).
If I use "safe mode" so my system can see 1,3 tera available, wich is normal for a raid mirror configuration.
I hope to find a solution quickly.

Maybe. If the current disk-drive has an IDE interface, then your 500GB disk-drive already is the largest IDE disk-drive ever produced. Or, if the current disk-drive has a SATA interface, then the sky (or the thickness of your wallet) is the limit.

you could have two resons for the issue.

1. you disk itself is having a issue
2. the enclosure adaptor ( not the power ) could have a issue.

Call LaCie. Your drive may be eligible for extended warranty support where your power supplies may be replaced FOR FREE.

It's all about the interfaces.
The Quadra has four interfaces: • eSATA • FW 400 • FW 800 • USB 2.0
The triple has all but the eSATA interface listed above.
For doing video work you want a big drive with a fast interface. If you have eSATA available then that's the fastest. If you don't then you're just as well off to go with the triple interface. The FW 800 would be the next fastest, then the USB 2.0, then the FW 400.
Because of the way that data is transferred I believe that when doing video work you would be best served by the FW 400 instead of the USB 2.0 even though the USB is faster I don't believe it is a full duplex communication so the FW 400 is actually better for video.

not sure if it will help, but try setting upnp active in your windows services. seem to remembrr my network assistant not being able to see my lacie network drive due to this in the past

check wires connecting them together first, ok?

then, turn off the LaCie, connect to your MacPro, and then turn on the drive..

that should show as a mounted drive.

need printer drivers update?
