Seagate Technology 200 GB USB 2.0 and FireWire External Drive ( ST3200823A-RK )
Plays well with Mac
Been using the Seagate for a few months.  Like most back up products, you really won't ever know until something bad happens.  Recently I had to recover some files I trashed, (hard to do a Mac but possible if you try).  Files were there just fine, saving some once in a life time photos.  Have not had that catostrophic failure yet.  However, with my Windows PC and another Seagate back up product I've had to recover several times and it worked just fine. The reason I picked Seagate this time. <br /> <br />As others note Mac install is up to Mac expectaions, clean - fast. <br /> <br />Plus+ <br /> <br />+Software works well with Mac.  Every few days it asks if I want to back up.  I turn on the drive and say yes.  If I say no, it will ask again a few days later. <br /> <br />+You can turn the drive off when not in use. <br /> <br />Only one minor Minus - <br /> <br />-While not loud the drive makes enough noise to completely drown out the iMac and be noticable.  (To be fair the iMac G5 is very quiet there is no way you could hear the drive over any Windows desktop PC I've been near.)  You can turn it off when not in use, so noise is not really an issue.  I've been told the drive is quiet by most standards. <br /> <br />I would buy again.
