1 out of 5 eggs2 of 2 Failing after 24 Hours

Pros: None.

Cons: After 4 years of being on my shelf, I finally opened them to use as backup drives while I build a new RAID array. Both drives exhibit the dreaded "Buffer I/O error on dev sdX".

It's sad that these things are so unreliable as to force people to use a RAID array to backup a RAID array. I guess the Hitachi's are now the top ranked drives. Funny, they used to be called "Deathstars" instead of "Deskstars" because they had a horrible failure rate back in the early 2000's.

4 out of 5 eggsHappy Overall

Pros: Inexpensive when purchased
good quality, and price for the storage size

Cons: green drive causes a little latency when accessing them for the first time after extended down time

Other Thoughts: I've had 2 of these running in my machine for the past 4 years, and am pretty happy overall with their performance. I use them primarily for movie storage and playback. They are the first "green" drives I've owned, and it took a little while to get used to the latency when trying to access then for the first time after some extended down time, or when watching a movie stored on them, and the picture would pause for a couple of seconds while a drive was warming up. Although a little annoying (this is the only reason I didn't give them 5 eggs), it's not enough to stop me from buying more green drives in the future.

1 out of 5 eggsIF YOUR DRIVE STILL WORKS SET PARK TO TIME TO 300seconds

Pros: Alot of storage when drive came out, got almost all my data off it before a partition disappeared and drive became unusable (minutes of inactivity) from retrying to read what couldn't be read.

Cons: Failed just after warranty
Apparently heads park every 9 seconds of inactivity
(60,300 park/load for 6,500 hours of use)
542 reallocated sectors out of 2TB should be usable but I'm assuming the heads aren't working properly because dysfunction has exponentially grown.

Other Thoughts: Never bumped during use, low temperatures with airflow, the drive damaged itself.
Forums filled with similar info.
I set drive aside for a couple years, started tinkering with it again (SpinRite,, MHDD, DOS6 format /u , HD Tune 0 fill.... tinkering)
I figured i'd write this to warn others.
IF YOUR DRIVE STILL WORKS SET PARK TO TIME TO 300seconds AND COPY YOUR DATA OFF OF IT!!!

1 out of 5 eggsThe worst HDD I've ever bought!

Pros: 64MB Cache, 2TB, a lot for the money... at the time of purchase

Cons: They drop like flies!

Other Thoughts: I bought 3 of these to make a RAID, as you will find out, 'Green' HDD don't work for a RAID because of their variable RPM's. After swallowing my pride, I decide to keep them and keep them stand alone; so far, 2 out of the three I purchased have died. When I say die, I mean really die, not even Spinrite would bring them back, one of them, the circuit board died and the drive would not spin, the second one says the drive has "Too many bad sectors", whatever that means.
Anyway, I have some Seagates that are about 8 yrs old and still kicking, the first one of these died after a few month.
My advice, stick with back HDD, stick with Seagate; you don't want to loose 2 TB of data on one swype

2 out of 5 eggsMore Failed Drives...

Pros: Quiet and fast enough.

2 out of 5 eggs4 years of light usage = failure

Pros: Worked okay as a backup drive.

Cons: Failed after 4 years of light usage, 1 year out of warranty. Not recommended -

Other Thoughts: This drive was primarily used as a backup, which meant that heavy read/writes cycles were rare. I was hoping that this would outlast a much older primary Seagate 1TB drive, but it died before.

My Seagate continues to hum along while this drive has crashed and burned. Between this and several other WD portable drives failing, I'm pretty turned off to Western Digital storage as a whole...

5 out of 5 eggsGreat drive great price

Pros: Had this drive for 3 years. I use it for storage, and do run games from it, though rarely. Speed is great for the type of drive it is, no complaints.

Cons: None

1 out of 5 eggs3 Year Drive

Pros: Lasted 1 year more than their warrantee. I have 4 of these in a RAID5, so luckily only 1 died so, I didn't lose all my data.

Cons: It lasted 1 year more than their warrantee. I have this in a RAID 5, so I have to buy more for backup. Would definitely use another manufacturer but concerned about compatibility in my configuration.

Other Thoughts: I gotta hand it to WD for being able to manufacture a product that fails so soon after their warrantee expires. Unfortunately for them, there are many other companies that manufacture the same product that we can buy from.
