HAY,
I HAVE A 2 QUESTIONS ABOUT REDUCING CAPACITY OF AN HARD DRIVE.

SO, I HAVE AN 1024 MB HARD DRIVE, AND I NEED TO REDUCE IT TO JUST 10 MB (SINCE I WOULD USE IT TO INSTALL MS-DOS 2.0 WHICH SUPPORTED HARD DRIVES OF JUST 10 MB).

I HEARD THAT PROGRAM CALLED "MHDD" CAN REDUCE IT.
SO, HOW TO REDUCE CAPACITY OF AN HARD DRIVE WITH "MHDD" PROGRAM, AND WILL THE CAPACITY BE THE SAME AFTER REFORMATTING THE HARD DISC USING SOME OTHER PROGRAMS (FORMAT COMMAND IN MS-DOS COMMAND PROMPT)?

OK, I WOULD LOVE SOME REPLY, BUT IF YOU DO NOT, IT IS OK, AFTER SOME TIME I THINK THAT I WILL FIGURE IT OUT MYSELF, BUT I WOULD PREFER REPLY.
OK, BYE.
YBY

use HPA command in MHDD .

OHH, OK. THAT IS GOOD TO KNOW. I WILL CHECK IT.

BUT ONE MORE THING:
IF I REFORMAT HARD DISK WITH FORMAT COMMAND IN MS-DOS, WILL THE HARD DISK CAPACITY LIMITATION BE THE SAME AFTER THAT?
YBY

Yes.

P.S. Please stop writing in all capitals - in Netiquette, it is equivalent to SHOUTING. Thanks

Correction : instead of using HPA why not use CONFIG command setting the MAX LBA to desired value ?
it is permanent and more transparent until you re-CONFIG again.

WELL, SORRY FOR THAT, BUT I DO NOT SHOUT. IF I WANT TU SHOUT I PUT THIS SIGN "!!!".
BUT I ALWAYS PUT THIS SIGN "." AT END OF MY SENTENCE, SO I DO NOT SHOUT. AND YOU WILL GET THIS SIGN, SO YOU CAN BE SURE, I AM NOT SHOUTING. ":P"
I MEAN, SORRY FOR THAT, BUT I NEVER PRESS "CAPS LOCK" BUTTON. UNLESS IF IT IS REALLY NECESSARY (LIKE WHEN I AM WRITING IN C++), BUT ON INTERNET I ALWAYS USE CAPITALS, BECAUSE I AM TOO LAZY TO PRESS CAPS LOCK. I WOULD NEVER SHOUT, IF I EXPECT TO GET SOME HELP FROM SOMEONE. OR IN ANY OTHER WAY. I DO NOT LIKE SHOUTING. BUT CAPITALS-I JUST DO THAT-IT'S HABIT.
SORRY.


OH, OK, GREAT TO KNOW, MHDD, IS GREAT PROGRAM.
THANKS FOR YOU REPLY.
YBY

CONFIG?

WELL, OK.
YOU KNOW WHAT, I WILL TRY BOTH OF THOSE COMMANDS.
AND I WILL SEE WHICH ONE IS BETTER FOR ME. (BECAUSE WHEN I CUT OFF SIZE OF AN HARD DISK, I NEED IT TO REMAIN AFTER I FORMAT IT WITH MS-DOS, SO THAT I CAN INSTALL OLDER VERSIONS).

THANKS FOR SUGGESTION.
YBY

May i know why do u want to do that?
there are for sure alternatives

Yes drive will not change capacity after format only way to restore capacity is by nhpa command in MHDD .

WHY?
WELL, BECAUSE I AM EXPERIMENTING, AND TESTING EVERY MICROSOFT'S OPERATING SYSTEM EVER SINCE THEY STARTED WITH MS-DOS 1.0, UNTIL THE LATEST WINDOWS 8. I AM PLANNING TO TEST ALL VERSIONS OF THEIR OPERATING SYSTEMS. (AT LEAST THE ONE WHICH ARE AVAILABLE TO DOWNLOAD FOR FREE (ILLEGALLY, I SUPPOSE). SO, I HAVE ALREADY TESTED MS-DOS 1.0 (PC-DOS 1.0), AND MS-DOS 1.25, AND NOW I AM TESTING MS-DOS 2.0. AND I SOW IN ARTICLE ABOUT MS-DOS 2.0, THAT IT SUPPORT 10 OR 15 MB HARD DRIVES. BUT NOT BIGGER ONE. SO, SINCE I HAVE 1024 MB HARD DRIVE, I WOULD LIKE TO CUT OFF ITS CAPACITY SO THAT IT CAN BE COMPATIBLE WITH THE OPERATING SYSTEM I AM TRYING TO INSTALL.
BY THE WAY, I DO NOT USE THAT HARD DISK FOR ANYTHING USEFUL, SO IT IS OK IF I PLAY WITH IT, AND CHANGE ITS CAPACITY.
THAT IS WHY.

WELL, ALTERNATIVE IS EITHER TO BOOT MS-DOS 2.0 FROM DISKETTE, WHAT I DO NOT LIKE, OR TO INSTALL IT IN VIRTUAL MACHINE (THAT IS WHAT MICROSOFT SUGGESTED TO ME), BUT I THINK THAT INSTALLING IT ON HARD DRIVE WOULD BE THE BEST FOR ME. I DO NOT MIND WASTING 1009 OR 1014 MD OF DISK SPACE IN ORDER TO SUCCEED IN INSTALLATION. BECAUSE I AM NOT SURE WILL MS.DOS 2.0 START FROM 1024 MB DRIVE (PROBABLY NOT), AND THINK THAT IF IT DOES, THAT IT CAN PRODUCE DAMAGE TO HARD DISC SINCE IT DOES NOT KNOW HOW TO USE SUCH A BIG DISC. (IN 1983, THERE WAS NOT SUCH THINGS LIKE 1GB HARD DISCS [AT LEAST NOT FOR PERSONAL COMPUTERS], SO THERE WAS NO NEED FOR MAKING COMPATIBLE OPERATING SYSTEMS FOR SO BIG DISCS. SADLY, SO NOW I HAVE TO MAKE HARDWARE COMPATIBLE WITH SOFTWARE. IT WOULD BE BETTER IF IT IS OTHERWISE, BUT SINCE HERE IS MHDD, I THINK I WILL NOT HAVE INCOMPATIBILITY PROBLEMS). SO, FOR ME IT IS THE BEST IF I REDUCE CAPACITY TO MAKE HARD DRIVE COMPATIBLE. UNLESS YOU KNOW SOME DRIVER WHICH IS SUPPORTED IN MS-DOS 2.0 FOR EXTENDING CAPACITY SUPPORT.

BUT IT IS NOT A BIG DEAL, SINCE CAPACITY IS NOT REDUCED FOREVER, AND IT CAN BE RESTORED, AFTER, IF I WANT.
YBY

THANKS FOR SUGGESTIONS.
I HOPE REDUCING CAPACITY WILL MAKE MY HARD DRIVE COMPATIBLE WITH MS-DOS 2.0.

Why not use a virtual machine?

WELL, I DO NOT LIKE VIRTUAL MACHINE.
IT LOOKS TO ME LIKE I AM PLAYING A GAME. IT IS ALL VIRTUAL. VIRTUAL MACHINE ONLY SIMULATES WHAT SHOULD HAPPEN WITH REAL OPERATING SYSTEM. BUT I DO NOT LIKE SIMULATIONS. I LIKE TO INSTALL AND TEST IT FOR REAL. AND VIRTUAL MACHINE REDUCES COMPUTER PERFORMANCE. CAN YOU IMAGINE OPERATING SYSTEM WHICH REQUIRE FOR EXAMPLE 32 KB OF VIRTUAL MEMORY RUNNING ON MACHINE WITH 4194304 KB OF VIRTUAL MEMORY.
VIRTUAL MACHINE REDUCES AVAILABLE MEMORY. I NEED TO HAVE RUNNING WINDOWS 7, AND BACKGROUND PROGRAMS FOR IT, AND VIRTUAL MACHINE AND ALL THAT WILL REDUCE FOR EXAMPLE VIRTUAL MEMORY FROM FOR EXAMPLE 4096 MB TO 1024 MB OR SIMILAR. THE SAME THING IS WITH PROCESSOR. PROCESSOR SPEED IS ABOUT 4194304 KHZ AND SYSTEM REQUIRE MAYBE 120 KHZ. WHEN I START WINDOWS 7, AND ALL BACKGROUND PROGRAMS, AND VIRTUAL MACHINE ALL WHAT WILL LEFT FROM PROCESSOR SPEED WILL BE MAYBE IN AVERAGE 2097152 KHZ OF PROCESSOR SPEED FOR EXAMPLE. SO MY MAIN COMPUTER PERFORMANCE WILL BE REDUCED BY MAYBE 50% AND THE REST WILL BE LEFT FOR RUNNING SECOND OPERATING SYSTEM. I KNOW THAT SECOND OPERATING SYSTEM REQUIRES ONLY 0.01% OF REMAINING SPEED AND MEMORY TO BE ABLE TO FUNCTION, BUT STILL I WOULD PREFER THAT IT HAVE MORE 'POWER'. DESPITE THAT OPERATING SYSTEM WILL NOT USE THOSE PERFORMANCE, BUT STILL, IT LOOKS BETTER IF I BOOT VERY OLD AND WEEK SOFTWARE FROM VERY NEW AND STRONG COMPUTER.

ANYWAY, IN GENERAL, I DO NOT LIKE VIRTUAL MACHINES. VIRTUAL PC REQUIRES WINDOWS 7 TO RUN (AS I KNOW), AND I DO NOT HAVE THAT VERSION. (OR NEWER). SO, IT WILL NOT WORK, ANYWAY. I KNOW THAT THERE ARE OTHER VIRTUAL PROGRAMS FOR SIMULATIONS, BUT I NEWER LOOKED FOR THEM, OR TEST THEM, SO, I DO NOT KNOW HOW TO USE IT. NOR I WOULD LIKE TO LEARN.


ANYWAY, GENERALLY, I LOVE REAL THINGS, NOT SIMULATIONS. THAT IS WHY.

SO, I FIGURED OUT THAT ACCTUALLY THERE IS NO NEED TO REDUCE THE SIZE OF THE HARD DRIVE TO INSTALL MS-DOS. I HAVE THE OPTION IN MY BIOS IN WHICH I CAN SPECIFY ONE OF SEVERAL DIFFERENT ACCESS MODES. IT TURNS OUT THAT MS-DOS, EVEN MS-DOS 2 WILL RECOGNIZE THE HARD DRIVE IF THE CORRECT ACCESS MODE OPTION IS SET, EVEN IF HARD DRIVE IS LARGER.

MS-DOS WILL JUST RECOGNIZE THE DRIVE AS THE DRIVE WITH THE MAXIMAL CAPACITY WHICH MS-DOS SUPPORTS, AND WILL SIMPLY 'NOT SEE' ANYTHING BEYOND IT.
SO, I CAN USE FDISK AND FORMAT COMMANDS TO MAKE A PARTITION AND FORMAT IT AND WILL WORK JUST FINE. EVEN OLD DATA WRITTEN BEYOND THE LIMIT OF ADDRESS WHICH MS-DOS CAN ACCESS WILL REMAIN INTACT AND CAN BE RECOVERED WITH DATA RECOVERY SOFTWARE LATER.

IT IS ACCTUALLY AMAZING THAT I CAN USE LARGE DRIVES, I USED EVEN 2TB DRIVE, AND MS-DOS INSTALLED JUST FINE. IT DISPLAYED IT AS SOMETHING LIKE 30 MB AND THAT IS IT. SO, EVEN WITHOUT REDUCING ITS CAPACITY IT WORKED.

BUT, IN ANY CASE THANK TO ALL PEOPLE WHO REPLIED.

WELL, pepe, I INSTALLED IT FEW YEARS AGO, BUT I JUST NOW FIGURED OUT TO WRITE IT HERE, JUST TO LET PEOPLE KNOW THAT I NO LONGER REQUIRE ANY HELP.
