NAME

	TD_SEEK/ETD_SEEK -- control positioning of the drive heads.

FUNCTION

	These commands are currently provided for internal diagnostics,
disk repair, and head cleaning only.
TD_SEEK and ETD_SEEK move the drive heads to the track specified. The
io_Offset field should be set to the (byte) offset to which the seek is
to occur. TD_SEEK and ETD_SEEK do not verify their position until the
next read. That is, they only move the heads; they do not actually read
any data.
IO REQUEST INPUT
io_Device preset by the call to OpenDevice()
io_Unit preset by the call to OpenDevice()
io_Command TD_SEEK or ETD_SEEK
io_Flags 0 or IOF_QUICK
io_Offset byte offset from the start of the disk describing
where to move the head to.
iotd_Count (ETD_SEEK only) maximum allowable change counter
value.
IO REQUEST RESULT
io_Error - 0 for success, or an error code as defined in
<devices/trackdisk.h>
