This is the best NAS on the market. It works quietly and efficiently and gets the job done. I had it up and running in about 30 minutes. I gave it a static IP address so that all my laptops could access the same content off this drive. Highly recommend this one.

Have had a couple of these drives connected to a 1Gb switch. They work fine with SMB and Windows networks, but we experienced big problems accessing from Macs using Tiger. The drives would perform ok for a few days then AFP access would fail - have to delete the .appledb file from a Windows machine or SMB connection. Also files over 2Gb tend to get corrupted - not good when backing up large video projects. Overall, disappointed in this drive & would not recommend them.

I just got Time Machine with my new Leopard operating system, and needed a big disk to back up to. Oops. This disk is incompatible with Time Machine. So I tried using SuperDuper to back up instead. Nope. Runs for hours, then crashes. The disk records a system log - it fills up with uninterpretable error messages. LaCie support doesn't know what the error codes on *their own disk* mean. Tried to return it - can't make returns without every bit of the original packing material and paperwork. Nice paperweight, though.

This HDD has a very poor interface to the cpu and the network. If you are looking to share a drive across the network you are better off getting the standard USB drive and sharing it from the server, or one of the network users. I have already sent my Ethernet drive back for the standard USB one.

Purchased this item hoping to use it with Leopard OS X on the newest iMac. Unfortunately, Time Machine does not support this drive as an ethernet network back up drive. It is recognized on the network but not by Time Machine. Attempted to use the drive as a direct USB 2.0 connected back up drive. Unfortunately, the drive was not recognized by either the new iMac nor an older one running 10.4. Online tech support was not helpful at all. If you choose to buy this product and need tech support, dig for the number and call them directly. Pity, on paper it would have been a great set up.

I bought this network drive from Amazon for use with a new Mac running Leopard. The IP Config routine that shipped with the disk was out of date and the newest version from LaCie could not connect to the disk via USB, direct (to computer) ethernet, or to an Air Port Extreme hub. Under Network, the drive was tagged as being connected via modem. Nor could it be connected using the Air Port disk Utility. Last, LaCie offers no path to uninstall the code created by their installer. LaCie on-line support folks tried hard to help, but after more than a week of back and forth, I gave up and returned the unit to Amazon. Thank you Amazon for no hassle returns.Short story: don't by this for a Mac running OS 10.5.1 until LaCie figures out Leopard and does a fix. This drive system was a a real disappointment from an otherwise good manufacturer.
