What can I do to improve HDD health? which factors affect on HDD health? How long does a hard drive last? What is the optimum temperature for a HDD?
To answer your first question: In simple terms you cannot improve HDD health as it's a mechanical device with move parts etc. Yes there are tools but I can't see how it may improve if not extend the life if anything.
Second question: The condition of the drive, how it's treated i.e. dropped, bumped around etc. Heat is IMHO is the number one threat to any HDD.
Third question: There is no straight answer, any HDD can fail at any given time regardless of the age. Others can last decades.
Fourth question: Recommended manufacturers numbers - use google. The cooler the better but not too cold
Edit: Made some corrections to grammar and spelling.
Thank you! My HDD works in 36C and I hope it's good! I really worry about the HDD failure! I had a Seagate Barracuda 500Gb SATA2 but it failed after 2 years (less that 2 years of course)!!!! the previous devices were perfect! for exampled I bought my 1st system in 2002 ans it worked properly for 8 years until I sold it!!! I worked very well and didn't have any problem!!!!!! I wonder why those components were so High-Quality but now only expensive components are High-Quality!!!!
I use multiple backups spanned across multiple drives, so the odds are in my favour that if I lose one drive I have another in place to pick up where that drive has failed.
I know honey but I don't have any money to have multiple HDDs!!!!!!!!! I'm planning to buy a monitor first! I'm going to sell this monitor to Louvre!!! Samsung SyncMaster 765MB!! older than MONA LISA!!!! LOL!
