What's your linux filesystem? Is it ext2 or reiser or something else? One reason I always use ext2 is because pqmagic only supports ext2. So far I encountered no corruption problem (it's not like I repartition every day ;-), except that linux's fdisk (e.g. to set active partition) will "correct" the order of partition.

As far as partitioning tools are concerned, there is no difference between ext2 and ext3. ext3 is nothing but journaled ext2. Once I learned that, I converted all my ext2 to ext3.

Another option is the Acronis Partition Expert... which also supports most of the linux FS's. And it uses a linux kernel as it's base even though it sometimes looks like a Windows program. The only FS it doesn't handle is XFS (JFS too?) and I expect that it will whenever they switch to a kernel that natively supports XFS.

I use Acronis Partition Expert, which understands more formats than I have heard of. It happily recognises Linux swap parts and Reiser parts. (As do all the Acronis tools, they install cygwin as part of their main install which is presumably why they can handle it) I haven't tried it on anything mission critical yet, but if you can wait a few days I will have used it to do a resize/move on a Reiser part. -- Tim Nicholson BBCi at http://www.bbc.co.uk/ This e-mail (and any attachments) is confidential and may contain personal views which are not the views of the BBC unless specifically stated.

Hi guys I used Partition Commander 8 to establish the partitioning I needed for the install of SuSE 8.2. I don't know if any of you found the same problem of conflicts between partition software - in my case PC8 - and linux bootloader (GRUB)- but I found it essential to uninstall PC8 after configuration of the partitions and prior to the installation of SuSE 8.2. I learnt this the hard way having to reinstall all the software!! Not sure if this will help you with your install. Humvee On Tue, 2004-01-06 at 01:38, mjt wrote:

Yeah, they're not that expensive these days ... especially the IDE ones. I've run into one problem with partition tables, and learned this. To be on the safe side, make sure to keep all your "valuable" data in one partition. Like /home, this simplifies the backup procedure, because you really only need to backup this part, not the whole system. When partitions are concerned, I've once encountered that one version of a partition tool (can't recall which) skewed the partition table, by one cylinder. Made only the first partition usable, not the rest. I was able to overcome this, as I had a copy of the partition table and their starting points. Just a pointer to keep in mind, if you intend to keep a lot of partitions.

Actually, the drive in question has only Linux partitions on it. The problem has nothing to do with Windows, except perhaps that the PM people used some Windows info for their partition definitions (don't really know about that). Paul Abrahams
Paul: I've experienced your PM problem as well. It is no doubt true MS has its own ideas about disk layouts. I do not have the detail of the difference in the the LINUX world's and MS's view of partition formats. I was under pressure to get a project done so I picked up Partition Commander(PC) from VCOM, Inc. It has explicit support for ext2, ext3, and ReiserFS. I used PC for ext3 imaging as I worked through an Upgrade problem so as to save the current state of a production harddrive. It worked for me although the product does have a Windoze slant, some features need to be turned off. Page 53 of the Box product manual has a list of things I did not need for creating and copying ext3 partitions. Turning off some of those features shorten the partition coping from 4 hours to 40 minutes. Also when it copied partitions from one drive to another it had the annoying habit of Hiding the partition to "Keep the drive letters the same". Why for ext3 partitions? You have to manually unhide primary partitions, the extended primary partition does not suffer this issue. I do not know. Well, I got the job done but was not sure about all the problems. A further issue relates to the way the SUSE partitioner works and the error messages I saw coming from the LINUX fdisk utility. The difference in the way LINUX partitioner actually sets up a partition. My disks, two 40 GByte Maxtors, are configured in my ASUS A7N8X-E as Auto which is LBA which you know about already. I partitioned the first using the SUSE install YaST text mode which I prefer. It appeared very sequential, almost like it was partitioning using the raw Cylinders, Heads, and Sectors. It looked different inside PC. Once PC made a copy of the primary disk's to the secondary disk, PC reported very different Cylinders, Heads, and Sectors allocations. I just may be that these two partitions are different! I'm to busy to get out a raw disk editor, in fact I don't know one to use. I will find one or maybe someone could suggest one. GNU's parted is another partitioning utility whose manual I've printed but not read. It is high on my list of to do's in the next few days. It is worth a look as it is scriptable and could also be used in system recovery after a complete wipe out. It would be good if some knows where to find information about these different disk formats. Good luck Paul W. Abrahams wrote:

"runs natively under most or all the operating systems for which it supports native formats" means you can run the same utility with no relearning regardless what you have available to boot to use it. DOS is nice and small and boots fast even from a floppy. DFSee has a nice small image available for those who want to put DOS and DFSee on a little floppy and get the job done quickly.

I was under pressure to get a project done so I picked up Partition Commander(PC) from VCOM, Inc. It has explicit support for ext2, ext3, and ReiserFS.
I first learned about partitioning in MSDOS and it's never been a mystery since. Linux, Solaris, they look pretty much the same to me, perhaps I suffer from myopia or some such affliction.
I used PC for ext3 imaging as I worked through an Upgrade problem so as to save the current state of a production harddrive. It worked for me although the product does have a Windoze slant, some features need to be turned off. Page 53 of the Box product manual has a list of things I did not need for creating and copying ext3 partitions. Turning off some of those features shorten the partition coping from 4 hours to 40 minutes. Also when it copied partitions from one drive to another it had the annoying habit of Hiding the partition to "Keep the drive letters the same". Why for ext3 partitions? You have to manually unhide primary partitions, the extended primary partition does not suffer this issue. I do not know. Well, I got the job done but was not sure about all the problems. A further issue relates to the way the SUSE partitioner works and the error messages I saw coming from the LINUX fdisk utility. The difference in the way LINUX partitioner actually sets up a partition. My disks, two 40 GByte Maxtors, are configured in my ASUS A7N8X-E as Auto which is LBA which you know about already. I partitioned the first using the SUSE install YaST text mode which I prefer. It appeared very sequential, almost like it was partitioning using the raw Cylinders, Heads, and Sectors. It looked different inside PC. Once PC made a copy of the primary disk's to the secondary disk, PC reported very different Cylinders, Heads, and Sectors allocations. I just may be that these two partitions are different!
I'm to busy to get out a raw disk editor, in fact I don't know one to use. I will find one or maybe someone could suggest one. GNU's parted is another partitioning utility whose manual I've printed but not read. It is high on my list of to do's in the next few days. It is worth a look as it is scriptable and could also be used in system recovery after a complete wipe out.
It would be good if some knows where to find information about these different disk formats. Good luck
For cloning the two 40G drives as masters on separate IDE interfaces, I'd simply use "dd if=/dev/hda of=/dev/hdc bs=1024k" and go shopping.

I have a hard drive that works perfectly well under Linux but Partition Magic thinks it's incorrectly formatted. I've heard that there's some disagreement between PowerQuest (the company that wrote PM) and the Linux world over what the correct format of a partition table is; each thinks the other has it wrong. Does anyone on this list know about the disagreement and the best way to get around it? (The SuSE database yields nothing.)

Some partitioners complicate a very simple operation. Some weeks ago an ex-colleague and I installed SuSE 9.0 on his machine which was using what he considered the bees knees in partitioning software, it understood ext3, but not reiserfs and refused to boot SuSE - unknown partition and operating system. Now it was OK with RedHat and Mandrake which were both ext3. We found we had to install grub in the SuSE partition, then it recognised it as Linux, unknown partition and booted without problems. We've never experienced problems with dual boot machines where there was just the standard Windows partitioner available. Regards Sid. -- Sid Boyce ....

I am told there is a difference of opinion about partition marking between *nix and windows. We can handle their markers but they have issues with our sequence. Various solutions seem to be reformatting the Windows partitions with their format even though qtparted can do that. Knoppix 3.4 is out but I dont know if the partition problem has been fixed. I have used PM and find it very slow if you set it to do a drive you basically go to breakfast and it will be done after dinner. qtparted while requiring things done is stages takes only minutes.

Ok, here we go again: I just decided to give a try to GNU parted. Yep, error message, so I stopped. Here's parted's startup message. "Error: The partition table on /dev/hda is inconsistent. There are many reasons why this might be the case. However, the most likely reason is that Linux detected the BIOS geometry for /dev/hda incorrectly." [Bad parted]. "GNU Parted suspects the real geometry should be 4866/255/63 (not 77557/16/53)." [cyls/heads/sectors?]. "You should check with your BIOS first, as this may not be correct. You can inform LINUX by adding the documetation for mor information. If you think Parted's suggested geometry is correct, you may select Ignore to continue (and fix LINUX later). Otherwise, select Cancel (and fix LINUX and/or the BIOS now)." Selecting Cancel... "Information: The operating system thinks the geometry on /dev/hda is 77557/16/63. Therefore, cylinder 1024 ends at 503.999M." I also used Partition Commander to make drive copies and got the following as geometry from its information window. Cylinders: 4866 ....Heads: 255 ..Sectors: 63 The BIOS has multiple reports. When set to Access Mode = Auto Cylinders: 19161 ....Heads: 16 ..Sectors: 255 When set to Access Mode = LBA Cylinders: 4866 ....Heads: 255 ..Sectors: 63 When set to Access Mode = Large Cylinders: 1277 ....Heads: 240 ..Sectors: 255 Interesting results. Which information is right? The real way to find out is to get out your favorite low level disk editor and see what is where. Since I have a blank target drive and I'm short of time, it's time to throw caution to the wind a see what happens.

The dd command is useful for cloning. Beyond that my comment was more focused on the actual layout of a partition using the SUSE partitioner vs the acutal layout using Partition Magic or Partition Commander. When I view, using PM or PC, a partition completed by the SUSE partitioner the actual reported layout is different than creating a partition from PM or PC. I first spotted this difference when I created an ext3 partition set for LINUX and then copied them to the 2nd hardrive. The orginal looks like a raw drive partition and the copy looks like a LBA like drive layout; Cylinders, heads, and sectors. The difference is noted but why?
