[comp.os.msdos.misc] IDE drive-- is it really UNFORMATTABLE?

conslt01@zeus.unomaha.edu (02/17/91)

I have a question for you people out there who are technical experts.
I recently bought a new Packard-Bell 80386-25 system that came equipped
with a 124 meg IDE hard drive.  A small notice came with the system
that said "THIS DISK HAS BEEN PREFORMATTED AT THE FACTORY..." 
talking about low and high level formats...
and goes on to say...
"DO NOT USE ANY FORMAT PROGRAMS OR DEBUG PROGRAMS ON THIS HARD DRIVE.
IF THIS DRIVE NEEDS TO BE FORMATTED, IT..."must be sent back in to the
factory where they will charge you an arm and a leg to do it, I'm sure.

I would like to know what constitutes a debug program (Norton?) and if
this is true?  Are there drives out there that cannot be formatted by the
user?  I would like to know, because I have files on my hard drive I would
like to put on a partitioned drive, but the program they gave me to 
partition the drive states that I cannot repartition the drive without
reformatting the drive.  I have DOS version 4.x

Any and all help is greatly appreciated.  Thank you in advance,
						John G. Schroeder

If yours is like mine, the formating the warning label talks about is 
LOW-LEVEL formatting.  High level formatting done with the format command
works fine and is needed if you repartition the drive.


WARNING: This is my opinion based on my experience. Your milage may vary.
	 Read the manuals and make backups before doing anything drastic.

	I have a Toshiba MK-234-FCH 104M IDE Drive which "can be low level
formatted" per Toshiba.  Their hardware design allows for low level format
without screwing up the tables.  Not all manufacturers have this capability!
Generally, I wouldn't low level format unless I absolutely had to.  The current
1 to 1 interleave gives 920 - 970kbs transfer rate.  Using CHECKIT I get only 
540kbs average (1989 AMI Bios timing Problem) but get 13.7Mbs rate with
SMARTDRV.SYS installed.  New 1990 AMI Bios I'm waiting for should increase base
rate back to the 920-970kbs rate.
