i was doing a hard drive test on my pc its a wd blue 160 gb hard drive and when i was testing noticed it said warning and it had yellow around current pending sector and it said current 200
worst 198 threshold 0 data 9and status said warning what do i do i have a extra 250 gb hdd but i want to transfer all my data to the 250gb hard drive and i game on this pc

Based on the test results that hard drive has started to deteriorate and should be replaced under warranty. Do you have a backup of your data?

no but I don’t have much stuff

whatever i changed my hard drive to a 500gb
