Hi!
I have a computer that I have build myself. Mostly of the parts is less than 3 years old.
Although my harddrive is from my previous computer, so the hard drive is 5-6 yers old I think.

From that I can deduce that when you turn the computer on you only have it on for an a little over an hour. That is nothing, its trivial. I have drive with 400 POH with 86 cycles and I have only had it for six weeks.

What makes you think you need a new hard drive. Are you getting errors,. Are you getting any SMART warnings. If everything is working as it should don t try and fix something that is not broken.

Just make sure you do regular backups so that when the drive fails, which it will eventually, you are prepared for it.

Longevity of a hard-drive is often a crap-shoot. If it's a major manufacturers' brand (which is about all that is left), like the WD you list, then I'd stick with it if it's lasted this long with no problems (the parameters you list are pretty much usless except for the power-on time) and the stated MTBF on most hard drives is generally exaggerated:

Nothing will protect your data quite as well as a couple of reliable backups (to some other media---I prefer something optical, other people will have different preferences). 2 backups are much more dependable than just one...

Re the link in #2.

Read the comments about misunderstanding MTBF - they are right.

Always pop back and let us know the outcome - thanks
