Misleading device numbers in QtParted
 
Hi,

I do not know if any of you have had this problem before. The QtParted program which comes with the Dapper Drake release displayed wrong numbers for my partitions. For example, it displayed /dev/hdc6, while the actual partition is /dev/hdc8. Then based on the graphical display of the partitions on the top, I tried formatting the partition /dev/hdc6. But, it ended up farmatting the actual /dev/hdc6 which was in a different position. In fact, I lost some data due to this.

Has anyone else had this problem? I there a workaround for this problem?

I've never experienced that problem with Ubuntu Dapper Drake (or any other Ubuntu release).

Sorry I forgot to mention, I'm using Kubuntu (not Ubuntu).

Also, this problem does not crop up when I use fdisk from commandline. But due to this, I'm scared to recommend Kubuntu to my friends.

Kubuntu and Ubuntu are the same distro and use the same software repositories (i.e., the same QTParted).

The only difference between Kubuntu and Ubuntu are their default applications.

I knew that. I insisted on Kubuntu coz it has it on the Install Disc. Anyway do u have a solution to it?

Has no one experienced this problem before. If so, is there any specific way in which my partitions should be organized so that QtParted can handle them properly?

I just downloaded kubuntu 6.06.1 i386 image in order to replace my amd64-kubuntu with 32bit version. I have also windows XP x64 and had windows XP-32bit version. I had following setup:

300GB sata disk:
/dev/sda1 ntfs 20GB (XP x64 "C:")
/dev/sda2 ext3 30GB (kubuntu amd64 "/")
/dev/sda3 swap 1,5GB
/dev/sda4 extended
/dev/sda5 ntfs 200GB (win "D:")
/dev/sda6 ntfs 30GB (XP 32 "E:")

My plan was to resize /dev/sda5 -> 170GB and create 30GB ext3 partition for "/home" where I could backup my home-dir from /dev/sda1. Qtparted did the job and new 30GB partition appeared as /dev/sda6 and my ntfs-partition moved to /dev/sda7. It seemed logical but then I left-clicked "Format" to new partition /dev/sda6 and result was that it formatted my 32-bit XP partition (which was originally /dev/sda6). I checked with fdisk that new linux-partition number was /dev/sda7, not /dev/sda6 like qtparted showed. So somehow I can confirm this misleading behaviour.

It would have been better for me if it had been that XP x64 partition that destroyed, which is waste of blocks in disk. Well, now I can reinstall partitions however I want...

Is this topic known at ubuntu-forums?

Posted at kubuntu forums
 
I have posted the same post in kubuntu forums too. but no one had a solution to this. I think it is a bug in the current version of QtParted. I hope it would be fixed in the next release. Till then fdisk would be my choice.
