can hardrive be used as a flash drive?

[jojoroxas72]

i have a fls drive. but i'm worried about if it ever takes up space. buying flashdrives after flash drives
can be very expensive. since harddrives carry terrbytes instead of gigas, suppose if you don't need and old computer. can you use the hard drive as a flash drive? example, unscrew the case and use the flash drive CD? will it work?

harddrive are slower. it mechanical, high chance of physical failure
Are you using them as temporary storage or long term backup?
