Format big FAT32 partitions

February 27, 2009 at 08:21:58
Specs: Windows 2000

Looking for a (free?) format program---found only one & it required running Win-98 so now thinking of Caldera or DRDos as possibles(?). Information about or anyone know of a useful FAT32 format program for big HD? WHERE-IS?

Old-existing is 160 Gb with 32 Gb as fat32 and balance as NTFS, want to change that to half/half. Just baught new 500 Gb and would like to have two 100 Gb Fat32 partitions and one 300 Gb NTFS. Cluster size is unimportant at this time as will mostly be storing large photos.

There was another FDISK for HDDs, that can handle more than 64 GB.
It's available at the Microsoft home page.

Please send a reply, if you solved the problem !!!

The windows 98 or ME partitioning command, FDISK, and FORMAT work just fine on partition sizes up to about 127 gig. They don't need to run in windows. All you really need is a bootdisk for either 98 or ME.

I'm pretty sure 98/ME fdisk and format will work with larger partitions but there are problems with 98 scandisk, and maybe some other 98 utilities, with partitions larger than that:

(The 32 gig limitation there only applies to XP and win 2000.)

As already mentioned, for partitions larger than 64 gig you need the updated FDISK when using 98. The ME fdisk command does not need an update. Most of us just copy the ME version of fdisk to our 98 bootdisks and don't even bother with the official update.

I don't think the XP version of scandisk has the 127 gig limitation. XP itself won't allow you to create a fat32 partition larger than 32 gig but seems to work OK with one larger than that that's already been created.

Have mostly relied on Dos-7 (Win-98) to Fdisk & Format my harddisks but could never get either to work at sizes over about 34 Gb. Thats why was looking for other software. Thanks to all for the suggestions.

You shouldn't be having any problem partitioning and formatting drives of that size with the 98 versions. If you are, then something else must be going on. Some older bios' can't properly recognize drives above 32 gig.

Have been using this DOS version for many years, always had the 32 Gb past instances and old systems I am sure the limits were Bios related but current computers are 2 ASUS P5N-E motherboards/computers W/ dual core at 3.2 Ghz , (about 2 years old) so don't think thats my problem now(?) as already have new ASUS Bios update.

Also have an old ME boot disk---did not realize its potential until this forum so going to investigate +++ also downloaded the (new-to me) microsoft 80 Gb program, optimistic....

Apparently somewhere along the way Microsoft just decided that 32 gig would be the maximum size for a fat32 partition in 9X. I found that statement in several places. Here's one:

But that doesn't make sense since FDISK will create partitions larger than that and FORMAT will format them. One of the following must be true:

1) The 32 gig limitation applies only when setting up the drive from within windows and not from a bootdisk (I never tried it that way with a >32 gig drive.)

2) It only applies to Windows 95:

Here's an MS link that says 98 fdisk won't create a partition larger than 512 gig:

Well, microsoft, which is it--32 gig or 512 gig?

Classic M$ blither.

I thinks it's ~63GB for 98 and ~127GB for Me. Nowhere close to 32 or 512.

Note: I partitoned an 80GBG into 3GB and 'the rest'. Fdisk showed only 20GB total but had actually created the ~76GB part. Go figure.

If at first you don't succeed, you're about average.

Mechanix2go said "I partitoned an 80GBG into 3GB and 'the rest'. Fdisk showed only 20GB total but had actually created the ~76GB part. Go figure."

Interesting!!! Thats exactly the result-messages I get with Dos-7 on big HD, just never pushed it and actually tried to create the "large" partition, abandoning the effort when FDISK seemed not to recognize the actual size of the HD.

Must be a bit of MS obfuscation here.... ;-|

Have in the past been moderately successful in creating/formating big FAT32 by using Partition Magic-7 but even with that pgm sometimes did not get a useful partition---anyway, lost or loaned that CD and not now sure the pgm is even for sale.

Well, today (Sunday P.M.) is the big day! Already backed up all my data so now will start the resize effort on my 2 HD, wish me luck!
Will be off this forum until effort complete, so THANKS to all who responded with suggestions.

If you're not using the updated (or ME) fdisk then for drives larger than 64 gig fdisk reports the drive size as the difference between the actual size and 64 gig. So an 80 gig would show somewhere around 16 gig. I'm not sure if that's counting as binary--1024 bytes per kilobyte--or decimal--1000 byes per kilobyte. Maybe that's why your 80 gig drives are showing less.

I had heard the old fdisk would partition full size but only show that difference, as M2 mentioned, but wasn't sure if that always happened. Anyway, using the newer fdisk made that a moot point.

its very simple....
create a bat file.......
and type the following code in it......

@echo off
set input=
set /p choice=Type Drive you want to format with FAT32 File System: %choice%
echo y|format %choice%: /Q /fs:fat32


now run bat file and type your disk drive i.e. c,d,e ect....ect....

What that has to do with partitioning is anybody's guess.

Yeah, that sure beats just using the FORMAT command. It's so much easier using your batch file than just typing 'format C:'
