Hello. After scanning hard drive I have found 50 bad sectors. I do not know what to think about this. Is this a lot or is this some insignificant number. I have 160GB hard drive and I would like to know how many GB I am losing thanks to this bad sectors. What drive percentage is it? Thank you in advance for your answer.
This is insignificant portion of your hard drive. Usually, one sector is around 512 bytes. So you have 50 bad sectors so you have lost 50x512bytes which is unnoticeable on 160GB hard drive. Regarding question about drive percentage I think that you can calculate this on your own when you know how many bytes are in one sector.
