problems mounting fat32 partition

[Tom]

Hi,

I have just installed Fedora Core 3, dual boot with Win XP. I have a 
separate partition for my files and so on, and I want to access it from 
linux. This is the set up of my system:
hda:
- hda1 (Windows XP - NTFS ~15GB)
- hda2 (Files - FAT32 ~ 25GB)
hdd:
- hdd1 (/boot - ext3 ~ 100MB)
- hdd2 - LVM Physical Volume (containing swap and /  ~20GB)

This is recognised by the Hardware Browser, but when I try to mount 
hda2, it does not seem to exist in /dev, so unsurprisingly, I get the 
error: "mount: special device /dev/hda2 does not exist"

any ideas?
Tom.

Thanks, but that still doesn't explain why I can't find /dev/hda2 in the 
first place.

I have since found that booting into rescue mode from the install CD 
does find /dev/hda2 and mounts it accordingly. But it still doesn't work 
on a normal boot up.

After the boot in normal mode, at the prompt on a terminal, what the 
command "ls /dev/hda*" shows?

Also what's the output from these two commands (must run as root),

  fdisk -l /dev/hda
  cat /proc/partitions

Very odd... fdisk seems to recognise it, but nothing else does:

[root@localhost ~]# ls -l /dev/hda*
brw-rw----  1 root disk 3, 0 Jan 28 02:48 /dev/hda 

[root@localhost ~]# fdisk -l /dev/hda

Ok, have been playing around a bit and found that by running 'partprobe' 
I can get it to pick up the partitions on /dev/hda.

I think there is a problem with reading the partition table during the 
initial boot, as I get the error message: "Buffer I/O Error on device 
hda, logical block 0", just before it starts redhat nash.

Is there a way of fixing this, or could I include partprobe in the boot 
procedure somehow?

Please note that this is one sign of a failing disk. And the partition
table is *precisely* where you do not want a disk to fail.

Please run, as root,
smartctl -H /dev/hda

smartctl -l error /dev/hda

smartctl -t short /dev/hda
which will do a low-level check on the disk: wait a minute for that to
run, then do
# smartctl -l selftest /dev/hda
to see the results.

And make sure that you've got good backups.

James.

your hard disk is probably going to crash. file a bug in
bugzilla.redhat.com if you are unsure
