My computer all of a sudden started running really slow. I go to school in Grenada and the electricity isn't always very stable, I have a surge protector to protect against electricity spikes, but is it possible that the electricity dipped low and caused my hard drive to spin slower and get damaged that way? Just because this is my second hard drive ruined on this island. They were both Toshiba hard drives the first was in a toshiba laptop and now in a dell. Anyway virus scans and spyware scans came up clean, i ran multiple updated programs to check this so i am 95% sure this is not due to a virus or spyware. I ran a check disk and it found a corrupt block on my hard drive, and I am assuming it 'fixed' the problem but my computer is still running slow.

What do I do now? I have read that having one corrupt block isn't bad, and that most laptop hard drives have one corrupt block. So why is my computer still slow?

Do I just need to reformat and from then on my computer will run fine? Also if I reformat won't that erase the part that was marked by check disk as unusable, and windows will not avoid that corrupt part of the hard drive when i re-install the OS. Thank you for any help. When faulty HDD sectors are 'repaired' they are actually blocked from further use in the future, so there should be no problem with formatting and doing a clean install. Sounds like you have some sort of other issue besides the HDD like malware a virus/trojan or perhaps a new program installed that is eating away at your resources. Hit ctrl-alt-delete to open up your task manager and watch to see if any process is spiraling out of control.if you see one choose to 'end process' and see if your computer speeds up.then ferret out exactly what process it is and try permanently killing it. This can be a PITA, and to be honest I rarely spend the time to figure it out and rather choose to do what you have described.reformat/clean install.

Yes, if your HDD is has many corrupt sectors that it has to reallocate and remap (something transparent to the end user), then you will have very slow computer performance no matter which system it is - especially bootup. The articles I wanted to link from TSF are no where to be found right now.

Anyway, download, install and run Speedfan: Go over to the SMART Disk Status tab and choose the drive - click on 'Perform an in-depth online analysis of the hard disk' It will try and access a website and allow it permission to. Read the information it posts about your HDD and if possible give us a screenshot back or the rough contents of the condition report. Tiny fluctuations, especially dirty line noise which is not cut out of the PSU/cable transient filtering can damage a HDD very quickly. Ok there's the in depth report about my hard drive. I am not worried about virus/spyware because i can reformat and that will clean everything up and make it all better, but if there's a hardware problem i can't fix that by reformatting. Anyway also the report says that my power on time is too long.

Meaning my hard drive has been on for more than average amount of time, but my computer is only 1.5 years old and i have been turning it off every night, so it's on probably about 8-14 hours a day, could it be possible that dell sold me a computer that they made with a used hard drive? Also how do I remap a spare sector? It says that i have plenty of spare sectors and I should remap the files that were in the damages sector to a spare sector. How do i do that?
