Summary: Bought a refurbished 2007 Dell Vostro 1700. Lo and behold it had an empty slot for a spare hard drive! Dos drives, WOW! I had to fill that slot so I shopped around and found the twin to the one that already occupied the first drive bay. Works like a charm. I store some big file there, most notably full system image backups and massive chess game databases that total almost 20,000,000 chess games.
Summary: I installed the 320-GB version of this drive into an HP G72 Laptop, everything Was working fine for about 4 or 5 days - - - - Then the Drive started making squealing Sounds and would no longer boot! No Boot Found! This is the second bad experience that I have had with Seagate this year. I bought one of their expensive 2-TB Hybrid drives at the beginning of this year and it was defective right OUT OF THE BOX!
Summary: The good: fast shipping. drive was packed neatly in bubble wrap and anti static bag. installed easily. The bad: makes a click and beep / whine noise. makes it pretty frequently and regardless if the system is idle or active. updated my drivers and ran multiple diagnostics including Seagates own SeaTools and nothing gives an error. Win7 home premium and all updates installed, in a Toshiba Satellite L455-S5009.
Summary: I re-installed Win7 Pro from a previous bad hard drive. It worked like new and was very fast; a cold boot took about 30 seconds. How long this will last, I'll never know. I repaired a broken laptop with this and immediately sold it to a well-pleased buyer.
