Thank you all for the helpful replies and information. I've done some web searching today and just have a couple other (really "newbie!") questions. Thank you for your patience... this is new to me. I bought my Sawtooth over eBay about 5 years ago and have upgraded the RAM, added 2 more USB slots, and upgraded the processor over time... but have never messed with the hard drive. (And I do love the computer.... I need it to work for awhile longer!) Am I understanding you correctly that I could feasibly purchase something like the: ** 120GB Seagate Barracuda 7200.9 7200rpm 8.5ms 8MB Cache Ultra ATA/10 ** from a website like OWC for around $75. With this "drive", I could either: A) install it INTO my Sawtooth in the "second" drive available spot? (I didn't know there was such a spot/slot...) B) replace the current (27GB?) hard drive with this new, bigger drive of 120 GB C) put this new drive into a firewire enclosure (for about $50 more?), and use it as an "external" storage/drive IF I chose to do Option C, why would that (or would that) be faster than just buying an external firewire hard drive in the first place? I am not a technician in ANY way, but I did manage to follow the specific directions thus far to upgrade this computer. I primarily need the upgrades now to handle my work with Photoshop. Buying a new Mac is just not in the budget at this time. Thank you- Michelle -------------- next part -------------- An HTML attachment was scrubbed...
