    I remember hearing before that you should keep about 25 percent of your hard drive space free so the hard drive can operate more efficiently. Does anyone know if this is true?

    Well if you are talking about fragmentation and wanted to defrag....yes it helps having free space so that the drive can just write/read sequentially and hopefully not have to jump around too much. Defragging with free spaces makes it easier for the drive to reorganize the files in a more efficient manner.

    But it is not as if the hard drive breaks if you use all its capacity...

    On a system drive though it is generally a good idea to keep 15% free.

    And window's defrag requires 15% free to start defragging, however there are a lot of 3rd party options out there that are better :) (and don't demand 15% free).

    The number I've heard is 20%, but yes, it's best to keep the drive from being completely full - I remember reading that there's a performance impact if remaining space is low, but I'm not positive.

    Shoot, I'll buy a new hard drive if I have less than 50% free space.

    Microsoft's NTFS format likes some free space on the drive. Otherwise, there will be some performance degradation and possibly fragmentation.

    If you are just going to use the drive for just storage (not system drive), then you might be able to get away with less free space (like 5-7% free space).

    There's always fragmentation on NTFS whether the hdd is full or not. The performance degration is almost always due to the physical limition of hdd and fragmentation.
