About 1,5 months ago I bought Toshiba P300 3TB drive for my PC. From the beginning when I looked into HWiNFO there was one parameter which attracted my attention - "Number of Mechanical Start Failures: 6". I searched throught the Internet and it turned out it's normal for Toshiba drives. Number was always 6 untill two days ago, when I started to have problems with this drive. With some operations it started to make loud click sound and then spinning up. In a few hours it was getting worse and worse, but at the end it turned out, that there was a problem with power cable. I have fixed it but after that I noticed, that "Number of Mechanical Start Failures" changed to -1476193263. Why it's not displaying proper number now?
