Have you run memtest on it, Dave? It should be in the repo or already an option from the boot menu. You can download the live CD from http://www.memtest.org if you prefer. If your memory passes, it could be faulty/overclocked CPU or overheating. Check these things too. -c -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

If the machine is unreliable, any kind of hard computation (such as data compression) will have problems. Maybe the problem is caused by something bad in the F12 distro (such as new graphics drivers). I suppose you tried the LiveCD on the laptop, and it looks like F11=good, F12=bad. > If /usr/bin/ark is fubared, any idea how I can best put it right? yum reinstall of the correct rpm (kdeutils?). Try also "rpm -V" to check. But if md5sum and cmp randomly fail, the problem is not ark. The machine is unstable, for hardware or software reasons. -- Roberto Ragusamail at robertoragusa.it -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

So.. what I get is: -no problems when running on the F11 Desktopfor either the md5sum or the cmp, run in a while loop for a long time; -variable numbers of md5sum errors running on the F12 laptop (for example, will run 3 times with same checksum then 1 error); variable cmp errors(again, one or two clear runs then a pile of miscompares, then again several ok runs); -Ran memtest overnight without error; -tried the F12-KDE Livecd, sometimes ark opens the files, sometimes not (also tried various USB ports both direct & via a powered 7port hub with same results); -tried F11-KDE Livecd, ark opens all files without error. On the F11 Desktop, the ark "help-about" gives ARK Version 2.13 using KDE 4.3.4, on the F12 Laptop gives ARK version 2.13 using KDE 4.3.4, F11 Livecd gives ARK versio 2.12, using KDE 4.2.2, with yumex, I find that tar on the F12 is 1:22-10.fc12 arch 1686, on F11 is 2:1.22-4.fc11 arch i586, as I couldn't find any ark info through yumex, I had a look at /usr/bin/ark on both machines: on the F12 machine it is 54.7 KiB, on F11 is 143.2 Kib. If /usr/bin/ark is fubared, any idea how I can best put it right?

Well that's not totally true, the data could be in cache (for read) so with the sync command you are sure that all the bits are written to the physical device, but when you read the data may comes from the OS cache, may be that you can do a large copy (eg. copy 10-12Gb of data depending on your RAM/SWAP configuration) and then make a checksum of the data. you can umount the device, run fsck on it, reboot, remount the device and then issue an md5. If everything is right you should have the same checksum.

I take it one step beyond that. During my nightly backups, I have it create the hash for all my tarballs. Pretty simple to do. As an example: if you have backup /home/you, /etc and /root to tarballs: home.you.tar.gz etc.tar.gz root.tar.gz Doing something like md5sum *.gz > checksum.md5 will create and store the hash info in the file, checksum.md5 Then to verify, md5sum -c checksum.md5 If all goes well, you'll see something like: home.you.tar.gz OK etc.tar.gz OK root.tar.gz OK Of course, you probably knew all this anyways. -- Best regards, Chris “It is always better to have no ideas than false ones; to believe nothing, than to believe what is wrong.” -- Thomas Jefferson -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

The versions that Fedora carries should be able to understand this without the need for the z (or j or x). I found this on the list some time ago (one year?). So if the file is compressed with gzip "tar tvf xxx.tar.gz" should work as tar recognises the compression used. -- José Abílio -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
