I recently purchased a WDCB640GB hdd from a local IT shop for a backup drive (have 2 500GB ones in RAID0) . The drive started to slow down drastically , and lagged quite a bit . I had to back up my data , but some files were not readable , so i Reformated the drive ( full format) , and copywed my data back , but it did not improve , so i downloaded “Data Lifeguard Diagnostics” , and i saw the SMART status beeing a : X FAIL ( written in red ) . I could not even read the SMART disk information . So i rebooted , and the same happened . ( Other drives are green/good )
So i am pretty sure this drive is about to fail . Did i do something wrong , and it should work , or RMA immediatly ?
Extended test says error-08 too many bad sectors detected .
