Question about LaCie External USB 2.0 500GB 7200 RPM 500 GB Hard Drive
This is now the second hd that has the same problem in this past month. When I turn the drive on to boot up, i can hear the motor start, but then it stops and starts again, sputtering trying to get up to speed and it never does. One drive now doesnt even try anymore and the other one just started and I'm afraid that it will completely die on me soon.
What do you think?
Mine does a similar thing (start and stop for a few seconds when turned on) then the front light goes pale yellow instead of orange and it gives up. It may be coincidence, but on a couple of occasions when the power pack is left unplugged (so is cool) it has worked for a while. Perhaps others could try this. It would point towards a power supply issue. I do have 2 of the 500GB HDDs and have had the same problem on the newer one once or twice too. It is very worrying and I would certainly not buy anything else from LaCie.
Power outages or brownouts can trip up the eMac's switching power supply. That usually manifests as a failure to strart at all, but can occasionally appear as a partial latchup. To fully reset the eMac's switching power supply, remove all peripherals other than the keyboard and mouse, remove the power cord from the side of the eMac (to remove the trickle current drawn by modern electronics even when nominally off) and wait 15+ minutes. Then reattach the power cord only and start the Mac. This is for future reference; if your eMac did eventually restart normally, it should be OK now.
However, it would be prudent to use your OS X Install disc to run Repair Disk as described in Using Disk Utility and fsck, since if the Mac was writing to the hard drive when the power failed, that can damage the disk directory. In cases Disk Utility can't fix, DiskWarrior has proven invaluable.
You can find a basic USB-capable Uninterpretable Power Supply (such as the BackUPS models from APC) for around US$40 to $200 depending on battery size and features such as cable and Ethernet port connections. OS X 10.3 and higher have built-in support in System Preferences -> Energy Saver to recognize a UPS connected to the computer via USB and can gracefully shut down the Mac in case of an extended outage. Even the low-cost basic UPS models protect against momentary outages and brownouts, which besides being more frequent than full-blown outages can potentially be more damaging.

When the motor and the heads start getting noisy, clicking andwhirring, and the hard disk access time gets abnormally longer thanusual, that means that the disk can fail at any time.
Better saving all your data and get a replacement drive.
If this happened on two Lacie and they did not receive any shock, then call Lacie to complain : Contact Support
Let me know if you need info on how to get data recovery.
