Summary: I bought two for backing up my computer. The first one simply stopped working -- within two days! The second worked but had a firmware glitch that I later found documented on different forums: for the latest Mac Os the hard drive spins down to save power (good) but then does not spin back up (very very bad for a disk that you might use for external backups). This is a real pity as I have had great success with Lacie in the past, and was willing to pay a premium for it.
Summary: Although the drive was purchased in March; we've only been using it for the last three months. Last week the drive failed and we've lost all of the data that was on it. The drive never suffered any 'trauma'; was kept in the same place, same position; just failed. Trying to get 'support' from Lacie is extremely time consuming with them trying to get you to go to every possible 'paid' option for recovery, replacement, etc.; rather than just addressing your problem.
Summary: I've been using one of these for almost a year and a half now, and now the drive is slowly starting to fail: it frequently disconnects from my laptop and I have to power-cycle it, and certain files take absolutely forever to read/copy (probably because they're on areas of the disk that the drive is having trouble reading).
Summary: I really didn't use and the drive failed. Now returning to Amazon. Not happy at all. A year later and It still makes noise like the drive is bad. Now I am stuck with something that doesnt work.
Summary: I never write reviews because things usually work! I used this drive twice and it failed COMPLETELY on the 2nd job. Luckily the footage we shot was backed up on another drive or we would be dead in the water. Wish I could recommend this drive (have 4 of the 500GB rugged drives which seem to perform better) but buyer beware. They look cool but can't say the same for performance.
