If | you | replace | a | hard | disk | drive | with | a |
| much | larger |
| capacity | drive, |
| ||||||||
normally | you | will | create |
| a | larger |
| partition |
| size | on | the | new | drive. |
| ||||||||
When | you |
| copy | files | from | a | smaller | partition | to | a |
| larger | partition, | the | |||||||||
same | files |
| require | surprisingly | more |
| space | on |
| the | disk |
