A question about IOCTL_ATA_PASS_THROUGH_DIRECT

Using ZwCreateFile + ZwDeviceIoControl, I was able to send "EC" Command with "IOCTL_SCSI_PASS_THROUGH_DIRECT" from kernel mode driver, and recieve information from SCSI devices like USBs.
and searching around I've seen mutliple people who state that "IOCTL_ATA_PASS_THROUGH_DIRECT" doesn't work from kernel mode driver sending IOCTLs,
is it possible to send ATA commands from kernel driver at all? if so how?
Howdy, Stranger!

IOCTL_ATA_PASS_THROUGH_DIRECT can bsod if sent from kernel mode due to the buggy MS implementation. Best to stick to IOCTL_ATA_PASS_THROUGH from kernel mode.
SCSI and USB don't communicate using ATA protocol so sending native ATA to them using ATA pass through won't work. I am guessing your EC command was sent using IOCTL_SCSI_PASS_THROUGH_DIRECT, wrapped in a pass through CDB, and handled by the firmware of certain drives that support it.
Should that be kernel mode or user mode?
