How often you reformat the hard drive of your computer?

I reformat the hard drive atleast twice a year. I actually do it whenever my computer is very slow and has many viruses. I would say that there are really certain viruses and other harmful entities in our computers that are so difficult to delete.

hello learn i format my computer's hard discs once in two weeks, i know its bad for my pc, but i don have a choice, my computer becomes a fun place for viruses, i don know where they come from, the smartest anti viruses even gave up, so i back up my files and then i format it, am tired of them, last time i lost about 21GB of all my musics because of them! thats why i reformat it once in 2 weeks!

hi only when i have a problem or when i do OS upgrade

When my computer was using windows 98se, I use to format it twice a year. Now with a newer machine and now with windows xp, I format it 2 or 3 times a year. But I have this computer at work and I have Vista installed on it since January this year and so far I have already formatted it 2 times. It seems that the VISTA software has still lots of bugs, and reformatting it seems the only solution. The only problem is that I forgot to partition the hard drive and stash my files to a spare partition. So when the Vista Machine conked out(blue screen and it wont boot), all my files were deleted and I have to make do with the old files i stashed away in my flash drive. So it all depends on the type of software/Operating system installed in your machine and how reliable is it. So my suggestion is this "before you migrate to a new OS, let the technology age out a bit, for there are still lots of bugs in these new programs".

I format my pc like six or seven times a year, sometimes i just format and reinstall windows and sometimes i just feel like installing linux, of course i always backup a bunch of files to another partition...

I try to wait as long as possible between formats. I typically do it every year and a half to two years though.

I had to reformat my hard drive recently because the system 32 got lost and I don't even know why. I was suspecting that my 6 year old moved the folder or might have accidentally deleted the file. Anyways, it's a good thing because I also found a virus, so that was taken cared of as well.

Only if its the easiest way of solving my pc problems,what i do nowadays is to keep most apps on an external hard drive, so if i have to reformat, i have all my apps etc externally stored.

i reformat my drive very rarely
