Hi, I bought my 2-1TB Lacie 2big quadra in 2009. A few months ago I got a drive failure that even DiskWarrior couldn't recover from. Since I have redundant backups, I bought another drive (this time a 2tb Lacie single drive) and it's been working well for many months. But since I have this beautiful aluminum case on the 2big quadra just sitting gathering dust. I thought I'd triple its capacity by putting 2 Seagate 3TB Barracuda 7200k's in it (the 2 original drives were 1TB Barracuda's). I opened a trouble ticket with Lacie and got no help (i.e. it would void the warranty, the RAID might not work, the drives might not work), just a bunch of naysaying gloom. I even asked if their was a firmware upgrade for the chassis, but he didn't reply to that question (nothing's listed on Lacie's web site). Has anyone upgraded their 1TB Lacie 2big quadra with larger drives? The current 2big quadra's go up to 6TB 2-3TB. I would upgrade the power supply to take the larger drives (mine came with a 4A output; Lacie's selling a 4.6A with the drive now. If nobody's sure i can upgrade, maybe you could suggest a good external chassis that's quiet (big fan) and that can take 2-3tb drives. Not NAS, just FW800 (I'd connect it to my 2009 iMac). Thanks.
