You can.2] If you buy a new computer, can you re-initialize / re-partition the space which is there?
Thanks.
Your OS will have a disk management section where you can format, erase, create partitions.
There usually isn't a need to do that with a new computer as the computer is likely to come with a fresh install of whatever OS,
and, if you wanted to install a different OS, choosing a partition to install would be part of the setup process and you'd be offered the same disk management tools there.
and 2 other drives. One for daily and incremental backups from software, and one that the C: drive was mirrored to weekly. Because of the redundancy, I never really worried, and I never had a drive failure. Now that I'm retired, I'll mirror the C: drive a couple times a year just to backup everything.
