Re: [RndTbl] drive partitioning for Linux install
by Dan Martin 09 Oct '05

It turns out that my BIOS and ATA interface cannot handle HDs bigger than 137 GB, so I am switching my new larger drives to another computer and using its drives in the P3 - ie, lots of copying drives and partitions. The dd command has worked well, and saves me a lot of time compared to copying in DOS. Thanks. I have 2 other problems: 1) I need to copy a primary partition on one drive to a logical partition on another. I assume that if I do something like this: # dd if=/dev/hdc3 of=/dev/hda7 bs=1M that the boot sector of the primary will overwrite partition info in the boot sector of the logical partition, destroying extended partition info. Is there a way around this? If I create the logical partition with Partition Magic under DOS and copy into it, skipping the first sector, will that work? 2) I also installed Linux in my P4. When Linux complained it couldn't read the partition tables for sda, I let it rewrite them, thinking this was the new drive I put in. Instead, it was my serial ATA drive array. I have it configured to show up as one large drive under Windows. A large number of ATI video files were stored on the drive, which shows up in Linux as 2 drives (unallocated) and continues to show up in Windows as 1 drive - but now unallocated. The original drive was partitioned as a single FAT32 partition for the whole drive. My guess is that the data is still intact, and could be recovered if I put the right partition info onto the boot sector. Is there a simple way to recover this? If I created a new FAT32 partition in the "unallocated" space using Partition Magic in DOS or Windows, is that likely to recover the data? Also having some boot problems, but I think I can get around that. As a newbie, I'm getting into a little more than what Disk Druid can handle for me.

Another followup to HFS+ partition on a USB drive
by Mike Pfaiffer 05 Oct '05

Not a problem. Just a followup. Last night I had a friend format the area I reserved for Mac stuff on the hard drive. It was formatted HFS+. The Mac mounts it and the M$ partitions fine. The Mac sees the ext3 fs as a UFS (Unix File System) drive and does not mount it. Linux doesn't see the HFS+ partition. The hardware browser program in Fedora 2 says there is no file system on the partition. I haven't tried it under M$ yet. Past experience says it will only see the FAT32 partition. So far this drive seems to be happy with what I throw on it. Apart from the HFS+, everything is EASY to do with Linux.

Video DVD question
by Mike Pfaiffer 05 Oct '05

05 Oct '05

The end result is I want to burn a video DVD I can throw in a console unit. Here is what I've done so far... I've obtained a sample video file from the net (an AVI I think). I ran a program called videotrans to translate into a VOB file. MPlayer plays them both. Then I used a package called dvdauthor to take the VOB file and create a directory structure as well as the IFO and BUP files. It turns out I have to change the permissions of everything created by this package to 777 or I get a certain set of errors. Next I tried both k3b and (I think - this was over a month ago) growisofs separately to see if anything will burn. Apparently there were problems with the Fedora version of the cdrecord package so I updated it from the source. Both programs choke. The messages seem to be related to file names. I tried altering the names to what it said was missing to see if it would help. No joy. Am I close? If so, what am I missing? Is there a better way of doing this?

MUUG Meeting, Oct 11, 7:30pm -- GPS & Mapping with Open Source Tools
by gedetil＠cs.umanitoba.ca 05 Oct '05

05 Oct '05

[Posted to man.unix.general and other news groups] ------ Forwarded Article <di0ujb$jnd$1(a)canopus.cc.umanitoba.ca> ------ From gedetil(a)cs.umanitoba.ca (Gilbert E. Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, October 11. The meeting topic for this month is as follows: GPS & Mapping with Open Source Tools, Part 2 If you have ever been lost (and who hasn't), you will know just how important it is to know exactly where you are. With a handy little GPS unit, you can know exactly where you are in the world down to a few meters at the push of a button. In Part 2 of last month's presentation, Shawn Wallbridge will present on web-based mapping. He will primarily be covering Mapserver, a web-based mapping application by the University of Minnesota. This month is also the annual general meeting, where the new MUUG board will be elected. The group holds its general meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15pm, so the meeting can start promptly at 7:30pm. Don't be late, or you may not get in. (But don't come too early either, since security may not be there to let you in before 7:15 or so.) Limited parking is available for free on the street, or in a lot across Ellice from IBM, for $1.00 for the evening. Indoor parking is also available nearby, at Portage Place, for $2.00 for the evening. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Also note that MUUG maintains two mailing lists, called "muug-announce" and "roundtable". If you're not already on these lists, we encourage you to subscribe now: http://www.muug.mb.ca/mailman/listinfo/ The "muug-announce" list is used for monthly meeting announcements (such as this one) as well as other important announcements of interest to MUUG members. The "rountable" list is meant to be a forum for follow-ups to topics discussed at the meetings, or for round-table-style discussion on other topics that come up between meetings. Of course, for this to be effective, we need to reach a certain critical mass. So, please subscribe, and stay involved! -- Gilbert E.
