hard disk partitioning - less space


Hello.
I have 160GB ATA TOSHIBA MK1646GS HDD, and I had 3 partitions on it, however, when I deleted all the partitions with gparted, using Ubuntu LiveCD, it sees only 149GB. The former partitions were made using 'automatic' mode in Ubuntu installation. The 11GB seem to have disappeared along with / and /swap partitions. Right now I have 149GB unallocated free space and I want to install openSUSE, but I want to fix this mess first. What should I do to get 160GB free unpartitioned space?

I've tried gparted liveCD, however it ends with an error "no screens found" after trying startx, but I don't know if it would help anyway.

I would be grateful for some advice.
Norua.

Despite the fact that your drive is labeled "160GB" there is, sadly, only 149GB on the drive. I believe it has to do with the either the block, or the cylinder, count being a base-2 number.

Check out this article. It further explains the logic behind hard drive sizes. (Scroll down to the Hard Drive Capacities section.)

I believe it's not the case, because I had more space before deleting the partitions - I had 149GB on /home, and something like 11GB on both /swap and /.

Also, when I try to install Ubuntu, on step 4, when I try to manually set the partitions it say I have 160041 MB (just noticed it).
Is it possible to set the partitions through the Ubuntu installation without actually installing Ubuntu? :/

It should be - I don't know how Ubuntu's partition tool works, though. What I used to do was go through the partitioning section in the Debian installer, and after it formatted the drives, I would just do a hard power off (hold the power button until my computer turned off).

Installing Suse

You can also Partition while installing suse. I also agree with indienick about the size of the harddrive. 1KB = 1024B 1MB=1024KB 1GB=1024MB (160041MB = 156.2900390625 GB). Also, filesystems take up a part of the harddrive to record where the information is located. A windows file system does it in the first part of the HDD, other systems do a dynamic allocation.
Anyways, it is doubtful that you can get more than the 149 out of it and you can just partition with suse when you install. It's an easy and good partitioner.

No you didn't.
You mis-interpreted what you read.

160041MB=160041000000
160041000000/1024/1024/1024=???.
Have a guess ...

An example of the difference between Gigabytes and Gibibytes.
