We've had a high number of hard drive failures occur within the past 6 months. The systems are IBM manufactured with two Maxtor 160GB Serial ATA hard drives installed. I estimate the failure rate at about 30%. The failures have always occurred on the primary drive (master).
I'm trying to consider if we are doing anything on our part which is contributing to the harddrive failure rate. One of the things I'm wondering about is the software installation method we use.
We use a custom restore CD which does a bit by bit write to the hard drives. I'm unsure of the specifics as it was done by a third party we contracted. Is it possible for a software program to increase the chance of hard drive failing by doing something "unsafe" in the program?
