USB external drive: NTFS/FAT32 detected, ext3 not
 
Hello,

I looked around and it seems partitions have caused a lot of people problems, but I couldn't find one like mine:
I have a dual boot system, WinXP and FC5, and I also have an external USB drive. On my external, I have 2 partitions. One is NTFS, and the other I use for testing. I was able to mount the NTFS partition onto Fedora (using the kernel module appropriate for my kernel version). Now, the other partition, when I format it as FAT32, it is detected automatically and I can access it from Fedora (no surprise there, Linux can read/write drives of FAT format). However, when I format that partition as Ext3, Ext2, or Reiser FS, it does not appear anywhere in Fedora.

I do my partitioning work in Windows with Acronis Disk Director. Could that be part of the problem? I have even tried formatting that partition as "None". No matter what file type I format it as, it does not appear in Fedora, unless it's a FAT type of some kind, or NTFS.

Any help would be much appreciated.

I would remove the partition and then under fedora create it again and set it as linux partition. Then format it under linux.

Re read it again. What does the command as root ' /sbin/fdisk -l ' report.

Hello Brian,

Thanks for replying. The output of that command is:

Disk /dev/hda: 100.0 GB, 100030242816 bytes
255 heads, 63 sectors/track, 12161 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda6 35178 36481 10474348+ b W95 FAT32




EDIT - I forgot to mention that I have formatted that second partition as NTFS and merged it with my first partition, also NTFS. I have only NTFS and FAT32 on my external at the moment. Should I attempt to format the second partition as Ext3 and run the command again?

So I guess you want to change /dev/sda6 to ext3 correct?
If so then use the command as root ' /sbin/fdisk /dev/sda '
Hit ' t ' for type, select partiton' then type ' 83 '
Hit ' w ' to write and save.
Run command ' /sbin/mkfs.ext3 /dev/sda6 '

Apparently it worked, given the console's reply.
But now, when I click that drive (which now appears, so that's an improvement), Konqueror gives me "Failed to mount device." That doesn't sound right, I don't need to mount ext3 drives correct?



EDIT - I restarted Fedora, the drive appears, 10GB drive label, that looks ok, but NOW when I click it, Konqueror says "An unknown error occurred."

How are you mounting it?
What is your mount command?
Do you have a line in /etc/fstab for it?
basic would like this.
create a directory in /mnt and name it say /mnt/sda6
Then the mount command ' mount -t ext3 /dev/sda6 /mnt/sda6 '

Yes, my folder in mnt is called ext3
My command is this:
mount /dev/sda6 /mnt/ext3 -t ext3 -r
