RawWrite

RawWrite

This utility reads a file on a mounted volume, given its file name, and
writes a number of blocks from the file to the named device and unit.

****** WARNING !! ******

This utility is dangerous ! It should not be used to write to a mounted DOS
volume. The data written to the device will almost certainly not be the same
as the old data, and the filesystem that has responsibility for the device
may misbehave or crash if the data is changed.

Dismount the volume before writing to the device !!

*************************************************

Command Syntax:
F=From/K/A, B=Blocks/N, K=KB/S, M=MB/S, T=To/K/A, U=Unit/N

From:	Enter the name of the file that is to be written to the device. This
		argument is required.
Blocks:	Enter the number of blocks to be transferred. This argument is optional
-
		if you leave it out, the program will read the whole file and write it
		to the target device.
KB/MB:	Enter exactly ONE of these arguments if you want to specify a block
		size. They specify the size of the "blocks" in kB or MB. One (and 
		only one) argument is permitted, but is only required in conjunction
		with the "Blocks" argument.
To:		Enter the name of the device (ie the Exec device, eg "usbdisk.device").
		This argument is required.
Unit:	Enter the Unit number of the device, eg 0, 1, 2, etc. This argument
		is optional and if omitted, assumes Unit 0.

****** WARNING !! ******

Be sure - be very sure - that what you have entered is what you mean, before you
type the Enter key. If you specify the wrong Device or the wrong Unit, you may
write over and destroy a volume with important data.

*************************************************

Notes:
1 The utility will check that the file exists and has enough data to satisfy
  the request. If the file does not exist, the operation will not be started.
2 If the (number of blocks * the block size) is greater than the file size,
  the maximum file size will be used. 
3 If the number of blocks and block size are omitted, the program will read
  the file in blocks of 1 MB, write them to the device, finishing with one
  partial block to complete the transfer.
