Hey, So basically, the internal hard drive on my mac has a weird problem. The intenral hard drive works perfectly in the morning after no use for a long period of time. All SMART tests pass, it shows as though theres nothing wrong with it. But as soon as we get a bit later into the day, nothing. Nothing picks it up, at all (we tried Ubuntu, TechTools, and CloneZilla in last ditch efforts to pick things up from it, they all picked it up fine in the morning, but later they saw nothing). This also all began happening after we suspect it overheated. I was planning on buying a new hard drive for it, then getting it put in there, but before I bought the new hard drive I thought I better double check that does sound like the problem. Thanks!
