Sector size

#1 Post by unaaa » 03 Jan 2017, 17:14

How did you restructure the sector size?

So far I've only managed to change the sector size by using

> [create]
> Disk
> ['partition table type']
> [Geometry]
> [Sector Size] 512

from there I managed to restructure the geometry from 1024 byte to 512 byte sectors, at least it is shown in this way by testdisk. When I now run another program i.e. rufus.akeo to create a bootable usb flash drive, I still get a message telling me that the geometry is using a 1024 byte geometry instead of 512 byte-structured sectors.

Further If I quit testdisk from the [Geometry] Menue > [Quit] > [Quit], the sector size jumps back to 1024 bytes which makes me think, the restructuring was just not safed/written to the flash drive.

Can anyone let me know how to restructure the sector size permanently?

thank you

TestDisk can not change the physical geometry. The modified sector size is only valid inside TestDisk.
