Part1: I have a pretty annoying problem:( A few months ago, I bought a new computer. Its hard disk was
SATA Hitachi 320 GB. I installed
Windows 7 and everything ran fine. But after some weeks,
Windows 7 started to hang. The only way to shut down the computer was to hold the power button. But when I tried to turn it on, BIOS didn't detect any HDD. I was really frustrated. After 15 minutes I tried again to turn on the computer again, and this time Windows 7 started perfectly! But the hangs of the computer continued in the same manner - I turn it off, wait 30 minutes maybe(otherwise BIOS doesn't recognize HDD, I don't know why) and I could start it again. After a week I couldn't start it for hours. Sometimes I could start it only on the next morning. I ran the
Hitachi drive fitness test and it complained about corrupted sectors. But can corrupted sectors prevent the BIOS from recognizing the HDD? Also it was a pain in the a** to run the fitness test, because BIOS recognized the HDD very rarely. My computer is in warranty, so they changed my HDD. It seemed to solve the problem.
Part2: After my HDD was changed with another Hitachi of the same size, I happily worked with my computer for some months, again with Windows 7. But on a perfect sunny day, my computer again hanged and the same story I described above, started again:( Is my computer eating hard disks?! Again the BIOS rarely recognizes the Hard Drive. But when it is recognized, Windows 7 starts perfectly, till the next hang. Again the fitness test says about corrupted sectors like the previous HDD. I ran S.M.A.R.T and a warning sign was next to the CRC. I am afraid to take a third hard drive to be eaten again:(
Thanks for reading my whole post. What could cause all this pain? I would be grateful to any clues you have!
P.S. I would like also to know what are the possible reasons that can cause the BIOS not to recognize the HDD sometimes.
Wish you all the best, Petar
