What Jerry is saying is that linux partitions always are numbered, just as: Thanks Bruce. I'm usually not quite so terse as I was in my post :-)

Well, I verified the numbering of my HD. It's as follows:

/dev/hda/ 55.8G Toshiba MK5021GAS

/dev/hda1/ 46.1GB HPFS/NTFS /windows/C

/dev/hda2/ 9.7G EXTENDED

/dev/hda5/ 509.8M Linux swap swap

/dev/hda6/ 9.2G Linux native /

Now I'm really confused. I seem to be missing /dev/hda3/ and /dev/hda4/. When I installed, I installed Xp first, then installed SuSE using defaults except for the size of the partition. So, SuSE sees this as a combination of two physical volumes with the Linux physical partitino divided into to logical volumes? You will only have an hda3 and hda4 if you actually created them. As

Wouldn't the MBR be its own physical partition? Not at all. The MBR is never included as a separate partition.

If i understand what I'm seeing correctly, I only have two Physical partitions. Partition Magic shpu;ld give me the option of creating either another physical partition of a logical one. If I create a physical one, wold it be /dev/hda3/? If I create a logical one, it would be /dev/hda7/? If /dev/hda1 and /dev/hda2 use the entire drive, then you will not be able to create hda3.

And, SuSE will see all this without my needing to renumber things? SuSE will see everything, but you need to tell it what you want it to do. You can run the YaST partitioner and it will tell you what you have physically and what the mount points are, and you can also use it to set up the mount points (so you don't need to edit /etc/fstab). the fsdisk command line utility will also tell you, but both should also tell you the start end end cylinders so you can get a picture of where things are on the disk. And, YaST will also create a FAT32 partition for you. While I have used QTParted to resize NTFS partitions, anytime you perform a resize operation whether Partition Magic or GNU Parted, you do risk damage, so make sure you are backed up. -- Jerry Feldman Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9

Yes, Bruce did pointed it out, but I wasn't totally clear as to what was meant. This is my first time trying to alter partitions on an already installed system. I guess maybe I got a little flustered. I do understand now. Partition tables are a real pain.

You will only have an hda3 and hda4 if you actually created them. As previously pointed out, the logical partitions in the extended physical partition start at hda5.

Hello, I'm surprised with such a partition table, usually primary partitions are called hda1, hda2 ..., the extended partition is always called hda4 by Unix or Linux and logical partitions begin at hda5. Don't try to resize a linux partition with partition magic, it won't work even for ext2/3 partitions and SuSE 10. You can use instead "Partition Manager" from Paragon. I use to write occasionnaly to linux partitions from windows with "Mount everything" from Paragon, and to write to NTFS partitions from Linux with "NTFS for Linux" from Paragon. It works well even with the lasts kernels. But when I've to write often - for instance for sharing my thunderbird mailbox - I use a FAT32 partition. Good luck. Michel.

I don't think you are right on this..... (scsi drives)

here's my /dev/sda

Device Boot Start End Blocks Id System /dev/sda2 * 2 11740 94293517+ 5 Extended /dev/sda5 2 7834 62918541 83 Linux /dev/sda6 7835 9787 15687441 83 Linux /dev/sda7 9788 11740 15687441 83 Linux

and /dev/sdb

Device Boot Start End Blocks Id System /dev/sdb1 * 1 7 56196 6 FAT16 /dev/sdb3 8 7827 62814150 5 Extended /dev/sdb5 8 109 819283+ 82 Linux swap / Solaris /dev/sdb6 110 118 72261 83 Linux /dev/sdb7 119 119 8001 83 Linux

Hello, My drives are all SCSI or SATA drives and the partition table is as I told !! But it doesn't matter. Michel.

It may be that SUSE's partition tool in YaST (which is really parted) will always name it hda4 (don't know, don't remember, and I'm not about to repartition my drive to find out) but that is very different from saying it's always like that in unix and linux.

I do believe DOS fdisk will always use this naming structure though. Perhaps that's what you were thinking of

The MBR partition table has 4 entry positions for the 4 possible primary partition entries. Partitioning tools tend to use those entry positions in FIFO order, but there is no rule that says they must, nor is there one that says the 4th must be the one used for the extended if there is an extended. It is not uncommon to have a disk with primaries at both beginning and end of disk, with an extended in the middle. When this happens, the extended will be xda2 or xda3 instead of xda4, and xda2 is fairly typical after configuring with M$ supported partitioning tools that first set one primary, then set one or more logicals. I don't think I've ever seen an extended as xda1. I think all tools reserve the #1 position for a primary. In any event, logicals are always labeled beginning with xda5. -- "Blessed is the nation whose God is the Lord." Psalm 33:12 NIV Team OS/2 ** Reg.

Wasn't this exactly what I said in the section of my mail that you snipped?

No. Multi-platform executable and M$-only executable partitioning tools generally don't ask you what to call anything, only what you want, which is why I excised the whole paragraph as having no relevance to the point I was attempting to show the OP or PP. -- "Blessed is the nation whose God is the Lord."
