LaCie Ethernet Disk Mini

LaCie Ethernet Disk Mini
Disk disappears off network and just ticks
LaCie Ethernet Disk Mini is a great way to store back-ups, itunes music, photographs etc but what do you do when your back-up disk fails?
Under two years of service and my second LaCie hard drive dies a death – but has it really? After a bit of checking around on the net, various threads point to a possible power supply failure which stops supplying enough power to the hard drive. We're talking about the black box on the power cable, not anything internal. It's a LaCie AC POWER SUPPLY Model No. ACU057A-0512 that is used. I'm not sure you can use another compatible power supply.
This seems a logical conclusion as the ticking noise suggests a possible lack of velocity with the hard drive, ie the tick would become a continuous tone if it was going fast enough.
LaCie Support
The support page for the LaCie Ethernet Disk Mini is very limited. Basically two options for Mac OS X: restart it or wipe it with a LaCie utility. The Blue button is rendered useless with the ticking problem, so a restart isn't possible.
The ticking and power supply issues are not documented at all with LaCie.
Also, LaCie don't advertise any telephone numbers, everything being done via support tickets. To start one you need to have registered yourself and your LaCie product which is quick enough to do.
I've heard that LaCie are poor at product support, so I'll post back the conclusion to this issue when they get back to me.
As I said, this is the second LaCie hard drive to fail in this way and I'm sure there are plenty of other people in the same boat.
