OK, I used all my harddrive on the first install of RedHat and then when I re-installed Linux I left 3gb of free space. When I enter fdisk in DOS mode there is no free space. How can I make it so that fdisk in DOS mode can read that free space and I can make another partition?

I'm going to possibly move this to the General forum as I am suspecting you mean actual DOS mode with a boot disk and a: prompts. If you mean something else, please clarify. If not, this is not a linux question

Cool

Indeed, with a boot disk.

Moving to the "General" forum where non-linux questions/topics go

I do believe that linux fdisk will be able to format that space for you, into a fat32 partition no less, but DOS fdisk is beyond me

Cool

How would I get into "linux fdisk"?

You need to be root and just run 'fdisk' - if that doesn't work, it's in /sbin.

How can I view all my partitions?

What do you mean? How to use fdisk? fdisk /dev/hda -l or fdisk /dev/hda, then get the prompt and do 'p'. It's got an 'm' at the prompt for a menu of options and there's the man page.

(For "hda", whatever your drive is or drives are, of course.)

OK, how come I have no free space? I should have 3gb of free space.....

You're a bit scrambled there. To unscramble it for a better view:

Primary
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda3 14 332 2562367+ 83 Linux
/dev/hda4 333 396 514080 82 Linux swap
/dev/hda2 797 1027 1855507+ f Win95 Ext'd (LBA)
Extended
/dev/hda5 797 1027 1855476 c Win95 FAT32 (LBA)

Looks like you've got a hole from 397-796. Unfortunately, all primary partitions are accounted for. I'm not sure what to do about that. I believe all logical drives have to be inside the area marked off by the extended partition - /dev/hda2 - I don't think you can just say "Make 397-796" a new logical volume. And you can't create a 5th primary partition. I may be wrong but it looks like you're going to need to... hm... I hate extended partitions. Maybe resize /dev/hda2 to take up 397-1027 and then create a /dev/hda6 inside it from 397-796. And definitely back up the data on the Win95 and really the whole computer. That's what *I'd* try but I'm not entirely sure it would go cleanly. I think it would, though. You might give it a shot or wait for somebody who was certain.

Afterwards, you might also try 'fdisk /dev/hda' then 'x' then 'f' to unscramble the table - I did that once when I got scrambled and it seemed to go okay but if it's not causing problems, maybe you could just leave that alone.
