Question: will it work with mid 2007 Macbook running Snow Leopard or Lion?
Document: Bought it for my mid-2006 2.16ghz 17'' macbook pro and it works great! Noticeably faster than the stock drive and runs quiet. As a side note you need to have the Snow Leopard (or better) installation disc (Leopard may work, not sure) as the Tiger installation disc will not work when using Disk Utility to format the drive.
I was getting frustrated with my 13" Macbook that I bought in 2007. It slowed down after the Snow Leopard upgrade and I was getting the Spinning Beach Ball all the time and I knew that something had to be done.My Macbook was standard with a 120gb HD 5400 RPM and 1 gb of RAM. So going to this 320gb HD with 7200 RPM was a huge step up and I love it. It's fast and quiet.
Love WD drives and this didn't disappoint. Swapped this into a late '08 MacBook to increase storage and speed over the OEM. Loaded Snow Leopard on it and really breathed new life into the old MB. The drive runs very quiet and fast. Not as fast as an SSD, so don't expect miracles if you're running SSDs in other machines. But since this is 7200rmp, it's fast enough considering the other limitations of the MB it's in.
I wanted more HD space than my 13-in Macbook originally came with (80 GB), so I originally upgraded to a 1 TB Samsung drive. That one arrived with a bad boot sector, so it kept freezing and then wouldn't reboot. Sent it back and got the WD Scorpio Black instead. After an upgrade to Snow Leopard (be warned, the drive won't work with anything less than Mac OS 10.6), I finally got it installed and working. It's quiet and fast.
It makes a slightly louder sound than my old HD but it runs well on my macbook pro thats on a snow leopard operating system.
I have the 2006 black macbook that came with the standard 120GB hard drive ! I needed a change and opted for this western digital 250 GB 7200 RPM !! The transition was flauless !! It's great !! I installed snow leopard in it and again it's great ! !
I got this when my stock hard drive was dying in my 5-yo macbook, and it's been a month or so and it works great. The increase in size (from my stock 75GB to now 320GB) also helped me be able to upgrade my OS to Snow Leopard from Tiger, so it's like a whole new computer!
I got this to replace a failed hard drive in my macbook. I did a clean install of Snow Leopard on this and have been computing away ever since. I can definitely notice the difference in speed between this and my old drive (7200 v 5400). I have absolutely no complaints/issues with this drive and don't even think about it any more after using it for a couple weeks. That's as it should be. :)
Love it on my Late 09 13" MacBook white unibody. Even the $24.99 Snow Leopard installed without problem on a empty new HD.If you plan to replace your Mac's stock HD, take this model WD3200BEKT as it has NO free-fall sensor and will not conflict with Apple's own. Watch out for the sibling WD3200BJKT which HAS free-fall sensor and is not recommended.
I just finished installing this drive in my MacBook Pro, and I can definitely tell a difference, for better and for worse.I had a clean install of Snow Leopard (10.6.8) on my 5400 RPM stock Toshiba hard drive (320 GB). After installing this drive, I performed a clean install of Snow Leopard (10.6.8). I timed the boot-up on both drives after installing all software updates.
Answer: As long as you can find drivers for it and the Macbook has SATA connectors then it will work.
