I have a Dell Optiplex 9010 machine running windows 7 Pro with a ATA WDC WD10EALX-759 SCSI 1TB drive. We Use a small piece of software for imaging our computers and the last time it was run I received a bad sector warning which made me go investigate the error. I checked Event Viewer and found a Disk error with Event ID 11: The device, \Device\Harddisk0\DR0, has a bad block. I went to go do a chkdsk and here is the result

No Bad sectors reported, However comparing this chkdsk with another computer running a 1TB Seagate drive it took much longer to complete. Not sure If I am just too paranoid or maybe something is going on with the disk that I am not seeing..
