Very Computer

Hello,

I don't know what to do.  RedHat is only seeing 7.8GB of my disk.
I have a Maxtor 36 GB IDE disk.  16383 Cylinders 16 Heads and 63 Sectors.
LINUX only sees 5240 Cylinders 16 Heads and 63 Sectors.

When I use fdisk x (expert mode and add the correct settings in everything
looks ok but the disk is still 7.8 MB.
Please tell me what I have to do to install the disk with a ext2 file
system.

NOTE ** I can install the disk in Win98 make a 36 GB partition format it.
Then when I load linux run :
mount -t vfat /dev/hdc1 /hdc1
This works fine but I need the FS to be ext2.  So I can chmod and chgrp to
use with Samba.  How do I fix this so Linux sees the blank disk correctly?
Pass command to LILO? hdc=16383,16,63.  But I don't know how.
Or is it something else?

Thanks for you help
Chad

Hmmm.  You did not say what version of Linux you were using.  I know from
experience that the older versions of fdisk will not work with big IDE drives.

If your fdisk is old (2.9w is near current), then you will need to upgrade.
I had the same problem with a 12.7 a while back.  Fdisk can be found in a
package called  util-linux-2.9.

You can get it from:
ftp://metalab.unc.edu/pub/Linux/system/misc/

Note that older fdisks will gladly partition the smaller size, but
windows/DOS fdisk might have problems with the partitioning (My DOS Fdisk
[came with drive... EasyDisk?] did not like what the old linux fdisk did, and
said the disk was corrupted... Upgrading linux fdisk solved the problem.

As for the LILO options, check out the LILO HOWTO.

Good Luck

P.S. Where did you find a 36GB IDE drive?  The biggest I found was 27.

Well, one solution would be to go get a copy of Partition Magic 4.0.  You
can use it to convert your drive to ext2 and it only takes a couple of
minutes.  Very easy solution, and it works well.

"Nobody" is rather confused about concepts, I suppose.
If the Linux kernel does not see the entire disk, then
it doesnt help to change the contents of the disk.

So, forget about Partition Magic.

What can you do?
Perhaps read the HOWTO at
http://www.win.tue.nl/~aeb/linux/Large-Disk.html

The part at
http://www.win.tue.nl/~aeb/linux/Large-Disk-12.html#ss12.1
discusses very large disks, but perhaps the problem comes
already earlier.

Anyway, all such problems are solved by reading the kernel
boot messages. They tell what the kernel thinks about the
situation. If that is not what is desired than usually it
helps to give explicit boot parameters.

These disks larger than 34GB have some additional problems,
and one may need a very recent kernel.
