2 years is well below the expected lifetime of a hard disk.
And, by the way, it's well below the expected lifetime of a battery also, IF (a big if) you run it with the power adapter connected as a rule and only occasionally on the battery.
- You didn't happen to opt for a 3 year warranty? On some Dell's this is offered (and not free).
- Why did you run that disk test? Did you expect any problems?
- Most Dell's come with built-in diagnostics (reachable via some function key, like ctrl-f11, check the manual, at boot). Can you run that for the disc and tell the results?
- Can you make and publish a speccy of your laptop? Go to https://www.piriform.com/docs/speccy/using-speccy/publishing-a-speccy-profile-to-the-web and post the link in your reply.
I have a Dell Inspiron 3558 laptop which will be 2 years old on October 11, 2018. The other night while I was on Dell.com looking up the cost of a replacement battery for the laptop I ran a hardware diagnostic test called Dell Support Assist. The test took about 5 minutes. After the test was done the test results stated I needed to replace my laptop's HD. The HD which came with the laptop is a Dell 500GB 5400 rpm HD; [ Part #400-ABCT ].
At the end of the diagnostic test results Dell showed the cost for a replacement HD was $149.00 if I shipped the laptop back to Dell to have it replaced by them or for $229.00 a tech would come out to my house or place of business and replace the HD there. Dell's page didn't list a part number for the replacement HD nor did it list the HD's size. Could my laptop's 500GB 5400 rpm HD already be starting to play out with the laptop not even 2 years old yet? The laptop's a low end Dell Inspiron 3000 Series which cost $452.51 almost 2 years ago.
