It was between this hdd, and the OWC FW hard drive, and I think i want to go with the Omega because i have a $50 apple gift card. I have a few questions though, does anyone know if: 1. What hdd is used inside the enclosure? 2. If it has a fan or is whisper silent? 3. Does this ext. HDD go to sleep (or whines down) when there has been no activity? 4. What is the little slit in the front of the drive? 5. Can I have 3 partitions, One for Time Machine, One for Other Mac OS files that i want, and than one more in Fat32 or whatever that would allow me to backup my windows computer at home? 4. Any other comments about the choice? http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=85A10F4B&fnode=home&nplm=TP946LL/A http://www.iomega.com/direct/products/detail.jsp?PRODUCT%3C%3Eprd_id=52194291&FOLDER%3C%3Efolder_id=55978377&ASSORTMENT%3C%3East_id=26890319&bmUID=1195422761017 Thank You For any Help.
