Re: Making a Windows disk a file on Linux
You've gotten some good advice so far, but I just wanted to mention another alternative that I've done on several different systems, including GNU/Linux and FreeBSD. If you really are interested in having a FAT32 or some specific filesystem available on a drive without repartitioning, then another workable solution is to create an empty file of the desirable size by using dd if=/your/file of=/dev/zero with other appropriate options. You can then format that file with a file system and mount it with the appropriate options. You can read and write to that file as if it were a regular filesystem. I've even used the above to make a "bootable" file for VMWare. It has been a year or more since I've done that and the specifics vary by OS (lately, I've been using FreeBSD more for that sort of thing), but finding instructions was fairly easy on the 'Net last time I needed to look. Also, if prodded, I could probably get you the proper sequence of commands on your OS choice after a few minutes refreshing my memory with the man and info pages. ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

[Completely OT] Biking for charity
Hi all, This is completely off-topic, but I need some help raising money for a charity bike ride I'm in. Here's the scoop. After an entire summer of riding my bike rather than commuting on the train, and even after getting hit by a car, I'm still not tired of riding :) As a result, I've been talked into entering "The Rodman Ride for Kids" (http://www.rodmanrideforkids.org/) with a couple of other bikers at work. So, why am I telling you all this? Well, because our team needs sponsors :) This 100 mile bike ride will take place on Saturday, October 2nd and will likely take my feeble legs all day to pedal it :) The ride benefits a number of different charities, the one we're riding for is Mass Mentoring Partnership: Mass Mentoring Partnership (MMP) works to ensure the availability of high quality mentoring programs to meet the needs of youth statewide. Through technical assistance, advocacy, and public awareness efforts, MMP seeks to expand mentoring and is a resource for mentors, mentees, and mentoring initiatives. Since 1992, more than 478 organizations and 3,000 mentors have received MMP training and support. MMPs goal is for each community to have access to an active and vibrant high-quality mentoring infrastructure to meet the needs of its youth. Donations can be made out to 'Ride for Kids' and can be in any amount you would be so kind to sponsor me with :) Please send any donation to me at my home address by October 2, 2004. If you don't have my address, please let me know :) Or, if you prefer, you can donate online at: http://www.rodmanrideforkids.org/site/content/donate.asp You can either choose to sponsor me directly, or our team. If you choose the latter, our team name is the 'Permabit Wheelers'. If a financial contribution is not possible at this time, then please at least keep me in your thoughts that day as I attempt to pedal almost 3x further than I've ever gone on a single bike ride :) [ OBLinux: I need to hire a rather senior Linux/Unix sysadmin.

Re: Making a Windows disk a file on Linux
Unless it's vitally important to preserve some of the obscure Windows-specific file attributes, tar seems like a fine solution. Otherwise, if I were doing this I think I'd create a partition that's just large enough to hold the collection of files in question, initialize that raw partition with some repetititve pattern (read: highly compressible, like all zeroes) then initialize that partition with a Windows filesystem, then use Windows to copy all files of interest to that partition, then dd that partition image into Linux file, then compress that image file, but noting whether any useful compression was achieved. If no useful compression I'd access it via straight loopback mount, else compressed loopback mount. BTW, somebody mentioned "logical block addressing" but note that LBA doesn't come into play at this level. ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

That is why I was asking about compressing stuff. There is a file system call squashFS that compresses filesystems. I just noticed that last night. I don't know if 2.6 kernels have it, but that might be an option. The other option for getting rid of extra space is shrinking the partition. I haven't played with those tools, but I'd imagine parted or a similar tool on a Knoppix CD is reliable.

FAT: Volumes from floppy disk size up to 4 gigabytes (GB). Maximum file size is 2 GB. FAT32: Volumes from 512 MB to 2 TB. In Windows XP, you can format a FAT32 volume up to 32 GB only. Maximum file size is 4 GB.

I believe this can be done using '-o loop' in mount, allowing you to
mount a file as a mounted file system. I haven't tried it myself, so I'm
not sure.
You'll just need to specify '-t vfat' or somesuch. And, you may also
need to specify something to force logical block addressing for the
filesystem. It will require someone who has done it before, or some
playing with on your part. But it should be do-able.

I don't know enough about VFAT vs FAT32 to know if the 110GB file will
pose a problem or not.

Are you just trying to preserve just the data, or are you trying to preserve the Windows system itself? If you are just trying to preserve the data, you could use mkisofs and create an iso9660 file system, then mount it like this: mount -t iso9660 -o ro,loop=/dev/loop0 windows.iso /foo All of the files will be preserved and usable (not writable, though), but it will no longer be a usable windows system. Or, you could just tar and bzip the filesystem, then extract it when you need it. HTH, Kenny -- Kenneth E.

I don't think you can do it that way. FAT32 is a file system.
But, you could use tar or zip to save all the files as an archive, or
simply copy the Windows directory tree into a Linux directory. The main
difference here is that the Linux permission structure is used on native
Linux file systems where FAT32 has some attributes, such as hidden.
Note that Win4Lin and WINE simulate Windows file systems as Linux
directory trees.
