defragging harddrive before boot up

witless_steve

I'm trying to find a good defragger bootdisk that will defrag the harddrive without the admin password.
Not sure if it's possible but I've been asked to see if I can find one.
Anyone have any tips?

Diskeeper has a pre-boot option that will defrag the system files that can't be accessed when the PC is running.

I can't remember if clonezilla puts back files where it found them or not.

But one way of defragging any OS is to back it up, do a clean install and restore everything.

Contig and pagedfrg could be run as scripts

Thing is you need at least 15% free space on the disk anyway otherwise it's a pointless exercise.

Also windows optimises for free space so you are more likely to have a contiguous area to drop files into. Almost every other OS on the planet searches for a contiguous area so it defrags each time a file is copied or saved. The windows way means slightly quicker saves and that you can do you defragging out of hours. The way everyone else does in means quicker file reads and either putting up with slowness during a defrag or having the machine turned on for longer so it can do scheduled defrags.

doesn't do an offline defrag, which is what was asked. Neither does auslogics.
