sudhish · #1 2nd December 2011, 07:08 AM

Hello EBDY,

I have an issue with fedora 14.....I have two hard disks on my desktop..The primary is dual bootable ..it has windows xp and fedora 14...... the secondary is 500 gb hard disk with 2 partitions....both its partitions get detected in windows but in the case of fedora 14 only one partition gets detected the other doesn't.

Any solution

As can be seen from the log, 500Gb hard disk is detected having a single partition, but it has two partitions.

There is no windows dynamic disk support in fedora

Code:

Device Boot      Start         End      Blocks   Id  System
/dev/sda1              63   976768064   488384001   42  SFS

Then why is one of the partition(250GB) of the same disk(500GB) detected ?

are you sure it's a sfs partition the second one too? can you use gparted and check if it sees the 2nd partition?

the reason why the partition is not showing up because must be missing value in the partition table. Fedora is able to moun the other sfs because probably it's not an sfs partition but an NTFS instead(wrong id#???). also you can double check in windows.

I have attached the screen shot of gparted......

In windows i find both the partitions of the disk to be of NTFS filesystem

so both gparted and windows are recognizing the partition as an NTFS partition, that means that there is an error in the id# of the partition table , that's why fdisk shows it as sfs, i think.

can you post the output of mount?

Code:

mount -l

also how much space do you have in your "movie" folder? 250GB or 500GB. It looks like the whole disk is mounted in movies , so i would check the content of the movie folder. It may be that because of wrong partition table data (maybe both partition are using the same UUID code) both patritions (which are theated by fedora like it's just 1) are mounted in the same place.

Code:

df /dev/sda1 -h

sudhish · #11 3rd December 2011, 06:52 AM

So what's the solution ?

Should i reformat the partition to NTFS

i would suggest you to format (using fedora) all the partitions you need in FAT32 (it's the best way to exchange data between *nix , win and mac systems) just to make it easier for the future.

sudhish · #13 3rd December 2011, 07:09 AM

I have attached the gparted view of the other hd also..Please let me know if i committed any mistake in its case

fdrake · #14 3rd December 2011, 07:15 AM

did you check my post #10? I added some commands. I just want to check if both partitions are threated just like a unique one. can you post the out put and check in the movies folder (/media/movie) that you have files belonging to both partitions?

Here are the details of mount-l and df /dev/sda1 -h:

I do not find the missing partition contents in movies folder.......

free space in movies folder is around 11GB/250GB
