How do you mean there is no port ? SATA ports exist...and there are many of them on MB...and HDD is on C: and D: drive..I had run scandisk, and there are no bad sectors..all seems fine...for now I didn't noticed problem with failure, but maybe it will appear again, because sometimes while I'm in windows, HDD led is active all the time...all of sudden, and then I cannot click on anything..it doesn't react, but I can move cursor...after 30 seconds, or a minute, everything gets back to normal..but sometimes also while having that problem, windows get frozen, and then when I reset my computer, I get that disk boot failure message..so I don't know what it can be..I checked with others HDD repair programs, and everything seems fine..and as I said, on scandisk also...
