750GB drive failed within two weeks
27 Dec 2011
Amazon Verified Purchase
Before I get into specifics, this caution - note the date and model on this (and other) Seagate internal hard drive reviews. Amazon lumps together drives of differing technology, size, and generation into one review pile. Look for the reviews that actually apply to the drive you're considering.
Even though I read multiple reviews warning that this 750GB drive is prone to failure, I'm an optimist so I bought one anyway. About two weeks later, my computer crashed with a BSOD (Blue Screen of Death) which turned out to be due to a bad sector that had developed in a critical system file. I ran a repair, got the machine working again, and two days later got another BSOD from more newly-developed bad sectors. The drive's built-in SMART diagnostic system is now predicting imminent drive failure. Given the number of people who have had similar experiences with this Seagate 750GB internal laptop product, one that has not been on the market that long, Seagate should stop selling it until they fix the problem.
If you're even more optimistic than I am and buy this drive anyway, be aware of another problem (albeit fixable) that nobody will tell you about in advance. This 750GB drive uses a new 4k sector size. Seagate advertises that they have built-in code that should make the sector size transparent to your system. While it seems to be true that the drive doesn't require you to install special software to accommodate its sector size, nevertheless your machine may require that you install an updated version of Intel's Matrix Storage Manager before the drive will function properly. You will get errors that don't tell you that this is the problem. I had to figure it out for myself by web searches, and if I had not had been computer literate I would never have gotten the drive working in the first place.
Note that all this feedback only applies to the 750GB drive. Drives of capacity up to 500 GB use a "standard" sector size and don't have identical issues. I have owned the 500GB drive in this same line for a long time with no problems.

Perfect for my Sony Vaio VGN N250E
16 Jan 2011
Amazon Verified Purchase
I needed a hard disk for my Sony Vaio laptop as I was getting cyclic redundancy check failures. I wanted a 1 TB hard disk (after all, I am spending the bucks, why not go for the trophy capacity) - but soon realized after some research that all 1 TB 2.5" hard disks in the market now are little thicker (taller) than most laptops have space for. Unless yours is a new laptop that can take a 12.5 mm thick hard disk, you have to stick to the standard 9.5 thick ones - which means you cannot get 1 TB, at least now. I am sure 6 months down the line, WD or Seagate or Samsung's gonna come up with a regular sized 1 TB disk. Anyway, I downgraded my capacity wish to 750 GB, and after some research, zeroed in on this one - reading some good favorable reviews on newegg and tigerdirect. I went with Amazon because of Amazon's great return policy (it is a hard disk to be shipped on a truck after all). Fit perfectly. Lots of space now, don't know what to do with it actually! Unless this one dies on me before its average life expectancy is over, I am going to stick to this 5 star review!

Great product!
12 Dec 2010

I used this HDD on my MacBook Pro instead of the original one. I expected it to be much faster as it's 7200RPM. But that's not the case.
Speed is ok while accessing data files, but it still takes some time when launching "heavy" applications.
My only problem now is trying to launch BootCamp on vmware Fusion (Win Vista on BootCamp runs great on its own). I still need to get that issue fixed!
I didn't notice any noise from the drive as I read in some reviews, so I believe it's quite enough for whoever works in the night when there's silence surrounding him like I do.
Great product and recommended for whoever is looking to expand his MBP's HDD.
