Question about LaCie 500GB d2 Quadra 500 GB USB 2.0 Hard Drive

Two units conflict when connected thru Firewire 400

I have two LaCie Quqdra units (500 GB each). When connected thru two firewire cables to my firewire 400 PCI card and both switched, both units don't appear on Win XP. Turning on just one (no matter which) they work fine. Connecting one thru firewire and the other thru USB 2 is also OK. I have checked my firewire PCI card with two external drives from other manufacturer and both drives worked fine. Bur with one of then connected via firewire and the other being a Quadra unit, the problem reappears. It seems that the Quadra unit doesn't like to see another firewire unit sharing the firewire interface. Quite weird!! Best regards.

Re: Two units conflict when connected thru Firewire 400

Windows XP and most pcs running it does not natively support firewire,as it was developed by Apple computers. Most Firewire ports on PCs are 4 pin. Your PCI card ( and I take it, its a desktop youre referring to ) should have a 6 pin connection. Firewire connections also have a 7 watt supply via the bus. You may need to open the computer and see if the molex jack on the card is being powered by your computers power supply. Two firewire drives, especially the power hungry Lacie quadras, may be to much consumption for the card. Hope this helps.

I have a LaCie Rugged Drive, with multiple interfaces (USB, Firewire 400/800). Firewire interface works fine. When I plug the drive in the USB port, it won't mount (MacBook Pro OS X), and a faint beeping...

the problem is that your lacie drive operates using the NTFS (New Technology File System) under USB which is the standard file system of Windows. Apple mac is not interopable with native NTFS therefore you need to install a read-write NTFS file-system driver on your mac if you wish to use it via the USB connection.

an excellent free mac NTFS driver can be found here-

download and install the software then restart your mac.

Having Problem with both LaCie hard drives being recognized on both macs

Try to connect to another computer, and see if it recognizes the drive. If Not, you can dismantle LaCie and take the disk out.

Connecto your disk to another external box (USB or Firewire) so you can have access to you data.

Can't accept Quadra 500 on my owerMac G5 Quad

Scrap LAcie!! Sounds like in this case, it may have been jostled around during shipping. None the less, Lacie drives are nothing more than bricks waiting to fail. Go Western Digital, but if oyu can, zip straight for Seagates!!!! Professional grade!! ALways check the cables, the ones that come with them are bottom bin cables, made by little singapore children with no fingers..... Invest in a good cables...a drive is only as good as the weakest datalink.

Cash on the warranty!!!

Keep me posted.

LaCie FireWire drive

I would seek out the latest drivers for the card in addition to checking to see the firewire card is properly installed. I would test the cable with another or ports. The D2 has a various array and combination of Firewire ports on each model. Also, try bringing the drive to another computer, to eliminate all other variables. Always of course, properly eject external hardrives and wait for confirmation whenever disconnecting it from the computer, and allow the drive to spin down before turning it off.

LaCie 500 GB hard Drive - does not register on my desktop

if it is a USB (or you have low disc space), it does take longer to show up on desktop and patience is required... on my iBook it takes over a minute for my Brick to show up... Whether it is USB or firewire, do try another cord (I had similar problem with my lacie firewire external... I used a different firewire cord and all was fine. If you have tried these already, I hope you find the answer... good luck
