RE: Inspiron One2310 how to replace a possibly deffective sata cable on hard drive

Agree100% with Ron. A bad SATA cable will not work at all. I actually had one. The computer would not boot, period.  An intermittent failure because of an almost broken wire would be rare, as intermittent failures are usually related to something moving and giving broken wire separation and rejoining. You will need to get the new cable to sort it out. They are available in several configurations, either straight plus or 90º, based on clearance near the hard drive.
