Question about LaCie d2 Extreme 250GB External with Triple Interface USB 2.0/Firewire 400/800 - 300790U ... Hard Drive

1 Answer

A lacie d2 extreme 250gig triple won't mount anymore

System profilers on all 3 of my macs only recognize that there is an unidentified device attached to the port (i've tried them all, fw400 800
& usb 2) with a data rate of (whatever port it's on). It seems hopeful that this is not a problem with the actual hard disk, but with either drive or cage electronics. (I'm trying to keep optimistic here as it's been having to do duty as the media scratch drive for a macbook pro so stuffed with apps, app-support, plug-ins, beta builds and extras that there simply was no way it could handle the raw media libraries. If you just have a pointer as far as what direction to look to learn more, that'd be fine. Or, anything really. I'm just looking for a starting point.

SOURCE: bought a new LaCie drive; isn't recognized by mac or pc

Lacie Porsche drives in my experience or infamous for not having the most durable bridge boards. The bridge board is a chip that has a chipset on it which take the SATA or PATA connection and send it to the USB and or Firewire ports on the enclosure. If the drive is powered up, you should get a small red or orange light on the front. When connected to either mac or pc ( porsches are MS_DOS formatted out the box ), if it does not mount or does not appear in DISK UTILTY, then it is a high probability that the enclosure/bridge board has failed and the drive ( if not making grinding, buzzing, clicking or beeping sounds) will have to be extracted and placed into a more stable enclosure. Hope this helps.

SOURCE: Lacie Drive making awful noise!

Lacie D2 drives in my experience are infamous for not having the most durable bridge boards. The bridge board is a chip that has a chipset on it which take the SATA or PATA connection and send it to the USB and or Firewire ports on the enclosure. If the drive is powered up, you should get a blue light on the front. When connected to either mac or pc ( porsches are MS_DOS formatted out the box ), if it does not mount or does not appear in DISK UTILTY, then it is a high probability that the enclosure/bridge board has failed and the drive ( if not making grinding, buzzing, clicking or beeping sounds) will have to be extracted and placed into a more stable enclosure. If the drive is grinding like you say, most likely the disk is physically damaged. If this is something you experience often, maybe you should consider power conditioners. if the drive is being moved around alot, you should be gentle with it in transit. Drive enclosures, look rugged and have flashy lights and metal enclosures, but should be treated like babies. Drives are feircely sensitive. They should be padded, kept away from magnets, and treated like laptops. Hope this helps.

SOURCE: Don't get it

I notice that you had issues initially installing the drive. Is it possible hat your actions as noted in the link corrupted the HFS+ formatting that was shipped on the drive?

Review this link

If as you noted THIS WAS THE FIRST TIME YOU USED THE DRIVE, you have no data on the drive to loose or recover.

Especially if you believe your actions may have corrupted the formatting of the drive, reformatting may be the appropriate response and could yield a working drive eliminating many return headaches. However if this does not seam reasonable contact with LaCie as to why the drive did not work directly out of the box may be appropriate. (I did confirm in the drive specs that the drive should have been formatted correctly for an apple computer -- windows users need to reformat the drive before they can use it )

I hope this helps

SOURCE: How to format the LaCie 500GB d2 Quadra for Windows XP??

This way it should work...
Connect your drive to the computer...
Go to: Start > Control Panel > Administrative Tools > Computer management.
A new window will appear...
Select Storage > Disk management on the left of the window.
Now you will see the different drives that are connected or part of your system.
One of the drives listed there is your LaCie, i think you'll recognize it by name...
Right-click on it, and select 'format'
In the new window, select the new volume label (as you like it), the file system (use NTFS), and set allocation unit size to default.
Make sure 'Perform a quick format' is not checked...

Then click OK. Your drive will be formatted now... Don't interrupt the process

SOURCE: la cie hard drive mount issues

I had the same problem and surprisingly, after many attempts to get the drive to mount with different connections, etc., the problem turned out to be the power adapter. If you've got the same kind of adapter on another drive, switch it out and see if your drive shows up. Good luck.

Deference Lacie d2 Quadra1TB/Lacie big disk ?


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.

Chances are the drive is bad. Try taking it to another computer- if it doesn't work there, then the prognosis is poor. Data recovery services are available, but pricey.

Disconnect the Lacie dvd drive, then reconnect it and open "system profiler" to see if the drive is now recognized under "firewire" or USB depending on your connection. If that doesn't work disconnect all peripherals and turn off your mac for 5 minutes. Start reconnecting your devices one by one.
