Disabling Write Caching

NTDEV

I was wondering how would i go about re-enabling write caching for a hard disk, if at all possible. It has been turned off by some stupid filter driver, and im wondering
how i would go about turning it back on.

I suspect it has been turned off for a reason, which might make this ‘stupid
filter driver’ not quite as stupid as you think. The documented way is to
send the specied IOCTL (IOCTL_DISK_SET_CACHE_INFORMATION) to the physical
disk. Your ‘stupid filter driver’ will most likely get in the way of this,
or the properties page for the disk would work for you right now. Perhaps
you could explain exactly what this ‘stupid filter driver’ is, as I am
pretty much disinclined to tell you how to hurt yourself without more
information regarding why you want to hurt yourself.

the stupid filter driver is the name i gave to the driver that makes my USB
flash card reader work properly :P. i want to re-enable write caching to it
because i basically use it as a removable disk. ive formatted it with NTFS
and it never is removed from the slot, so there really isnt a need to keep
write-caching off so… anyways. thanks for the help
