Summary: This drive died on me today after living at majority of its life (1 year) alone in an ATX "project" case. After only 124 power cycles, at least 20 of which occurred just today, this drive already has 103 bad sectors. Avoid.
Summary: This hard drive failed in 11 months. Initially I got warnings from S.M.A.R.T. that the hard drive is failing. In a few days, the hard drive started making loud grinding noises and the OS would hang after some time. I used this as a data drive (didn't install any OS on it). After reboots, the drive would work for a minute or so and the loud noise would start again. Samsung just replaced the drive with the same model. I hope it works a bit longer !!
Summary: Transferred all my critical data to this drive as backup when replacing main drive. Trashed all the data on the original main drive. Installed a nice new 1TB main drive and started to transfer data back from Samsung and the considerate little so and so just sat there clicking away with mechanical failure. Checked the samsung site and it is still under warranty. They will replace the drive but not recover the data.
Summary: This drive was included in my HP Pavalion M9457c. It worked perfectly for 120 days then had a hard failure. HP's warranty expired at 90 days. It was the primary drive. I was able to retrieve most of the files but couldn't boot the system nor access the original system image files. I'm disappointed in Samsung quality.
Summary: Worked great for almost 5 months, fast, almost silent. Then right in the middle of transferring a large video file... the dreaded click, click, click. And that was it... all my data gone! Luckily I hadn't got round to wiping the source drives. So I only lost a minimal amount of data, but that was just down to pure luck. Amazon has offered a me credit to buy a new drive, but I'm not sure if I'm going to accept this, as I've already bought a Western Digital replacement.
Summary: Lasted 5 days, then a cyclic redundancy error. I did a windows disk check (which took about 5 hours) then returned to find the machine hung at the bios stage with the drive emitting the dreaded mechanical click, click, click sound. Totally dead from that point. Luckily most of what was on the drive was backed up elsewhere, just lost about 100 photos and a few hours of my time.
Summary: I should have listened to the other reviewers here!! I will not buy fragile PC equipment through Amazon again! The drive arrived in a box big enough to carry 10 hard drives and when I felt the contents sliding around inside my heart sank. Sure enough after opening the box the drive sat inside with just a jiffy bag for protection.
