Lacie Hard Drtive not seen by system

by njs21 / January 30, 2010 5:10 AM PST

I am running OSX On aniMac, I have 2 Lacie 2Tb external Hard Drives connected. The system only recognizes one of them , it is a big disk extreme+. This is after regular use for over a year, recently it started acting up a little noisier than usual. But it was fully operational. About 3 days ago I got an error message warning me that I need to eject the drive properly and after that the drive was not seen on the desktop. I can not even run Diskwarrior to diagnose the problem. Any suggestions?

Does it spin?

Have you tried turning it off and then back on?

Usually when you get an error message like that, it means that the device dropped off the USB bus without any warning to the system.
Usually it means that the drive just died or the USB interface in the external case, failed.
That's probably not the case if the other drive is seen and is functioning.

Ahh, the beauty of RAID.

LaCie = bad
by mhollis55 / February 2, 2010 3:04 AM PST

The answer, unfortunately, is to not trust LaCie with your data ever again. For some time now they have been making drive enclosures that cook the electronics within them or cook the internal hard drive(s).

I have had considerable experience with their drives as a video editor. And I will not purchase their equipment due to assumptions they make that their enclosures will cool their drives without fans or they don't need to worry about moving much air because their aluminum enclosures will keep things cool.

If you can get them to work or mount one more time, I recommend immediately backing up all data on them to a non LaCie system. And never buy LaCie again.

So what back-up product do you use for Mac

I am currently using a Seagate 1TB drive and Time Machine.

Prior to that I was using a 500GB LaCie Firewire drive and Backup from Apple.

I don't have a problem with LaCie drives.

What backup strategy do you employ?

Don't like the Iomega drives,

been too many posters with problems.

BTW, you never mentioned that your Lacie just died. Unless you posted under a different name.

Check out the Seagate drives. Longer warranty, larger capacity and, usually, lower price

LaCie drive not recognized
by Jack J. / March 12, 2010 6:41 AM PST

You did not mention how your drives were connected or the model of your iMac. If you are using a newer iMac and Firewire 800 cable to connect the drives you could be experiencing the same problem that I am, where the first device is recognized until another is plugged in, then the first one dismounts. I think it's a problem with their Firewire interface. In any even the drive is warranted for three years, so contact them for a replacement. If the bad drive is not recognized when it it plugged in alone, and if it can't be reformatted using the Disk Utility, it's bad.

I'm using Omega now, so far so good. I had the same problem with (first device is recognized until another is plugged in, then the first one dismounts).
I come to the recollection the you need to buy two back-up hard drives. the first to do an initial back-up( then stored in a in a filing cabinet, the second to use as your everyday backup.

(NT) A very wise move.

LaCie drives

In reply to: Lacie

We have about 15 LaCie drives, only two have ever died and that was because the HD inside was past 4-5 years old. BUT. We have had some power packs die, I understand that LaCie have abandoned the 4 pin power plug system because the packs were dying too frequently, other than this issue, the drives usually don't show because of having missed a firmware update and then, if you've updated the OS you might consider a PRAM boot so as to "tell the computer" where these drives are.
