Quick question about reformatting

I've been thinking it's time to reformat, but I have one concern. If I take out my D drive and just reformat the C drive, can I plug back in the D drive after and use it as it was? I ask because I store a good deal of movies, programs and such on there and don't want to lose them.

 

yes, should be no problem

 

Thanks, I'll probably do this later in the evening.

 

just to make sure
the C and D is different partition or hdd ?
if it is 2 hdd, then no problem,
if 2 partition, just make sure only reformat C and it should be fine

 

Data will be fine, worst case you may have to take ownership of the files again because of NTFS permissions.

If you use Windows' EFS to encrypt stuff, decrypt it first or backup your certificates/private keys.

If you installed applications on D:, they may or may not work, depends on the specific app (if all its files/components/dependencies sit in the main app directory it should work, but some dump stuff into the Windows directory or who-knows-where, which will be missing after the reinstall).
Program settings stored in the registry/user profile directory will also be gone, obviously.
