I have noticed something. When I am formatting a hard drive using an XP boot disk for a full format, it takes a lot longer than when a computer with the same size hard drive is being reformatted using the PC Restore function that comes on new computers for the past several years.
I haven't timed it with a stopwatch or anything, but I'd say the PC Restore formats take about 10% to 25% of the time of an XP boot disk format job.
Why is this? Does the PC Restore just do a real half-assed format, just wiping file names and leaving the viruses on the disk, or has it found a better faster way, or is the XP boot disk format much more thorough?
I also have found a program called Active Killdisk that does really good formats and it takes a while too but it is the free version. The paid version has many more options for the formats it can do.
