I have a Toshiba HDTC940XK3CA external hard drive and CrystalDriveInfo is showing a Reallocated Sector Warning with a raw value of 8. I ran Toshiba's Diagnostic tools full test and it passed. I also did the diagnostic tools 6 months ago and the raw data was 8 then as well. It is still in the limited warranty period so my question is is the drive failing since the number has remain low and the same for 6 months? Since it passed the diagnostic tool I am wary of returning it and getting a refurbished one as a replacement that may even a higher count and passed their tests.
