Hi Uwe,
I am wondering if i can use hddriver to do a low level format of my CF card to 1024 bytes per sector.
is it possible to format media to 1024 bytes per sector

Re: is it possible to format media to 1024 bytes per sector
HDDRUTIL supports formatting media with a user-defined physical sector size, but the device you want to format must also support this. If a drive does not support to select the sector size, the corresponding option in the format dialog is disabled.
I don't think that any recent hard disk drive supports user-defined sector sizes or any other sector size than 512 bytes, and non-SCSI drives or memory cards have never offered this feature at all, as far as I know. There are very old SCSI drives by Fujitsu, for instance, that support almost any sector size that is a multiple of 4.
The advantage of formatting a hard disk drive with a physical sector size of 1024 or 2048 bytes instead of 512 bytes is an increase in the available free capacity, by the way. TOS cannot boot from such a drive, though, because it can only boot from drives with 512 bytes per sector.
