Hi,

I got some theoretical question, wich came up, while discussing
recovery-algorythms.
Is it possible to AVOID using the disk-cache while writing to the HDD?
Either way: by programming an appl. or by means of the OS

With ATA drive write back cache is generally enabled by default but
can usually be disabled in the OS. It is not always so simple as many
ATA raid controllers, for example, do not allow this.

If you're asking how to make a program that would disable it in all
cases (even when obstructed) without specific user intervention - I
don't know.
 
Write cache can easily be turned off with SCSI drives. With some ATA drives some OSs e.g. WinXP and DOS (if utilities are available for the drive) can disable write cache.
