View Full Version : cfdisk partitions and knoppix mounted drives disagree?

06-20-2005, 02:23 AM
Hi, just wondering if someone can help me understand why this might be... I'm waaay new to this (everything I know I learned here/have an unfinished thread in the windows forum), and ended up here as I suppose many do because during a Win2K reinstall my MBR and/or partition table(s) got trashed, and all my data was "gone".

Now that I've had a few stable hours in knoppix, and followed the great explanation in this thread (http://www.knoppix.net/forum/viewtopic.php?t=3311) for fixing partition tables, I've got a good (beginner's) handle on cfdisk.

Sorry that's a lot of preliminary for...

I have two SATA drives, so /dev/sda and /dev/sdb rather than hda and hdb, otherwise they seem to work the same? cfdisk has successfully restored my sda partitions, and reactivated the wandering/lost boot partition as it should have (btw why when there is only "free space" and sda5+ does it activate as sda2? but I digress...)

sdb shows up in cfdisk as one big drive (120GB) and a little left over, but the thing I don't get is, why do I correctly have mounted sdb1 2 and 3 in knoppix if cfdisk says those partitions don't exist? I'd love to just rewrite my sdb partition table as it was--and as knoppix recognizes it--but cfdisk says no go? Is there a way to rebuild the table as knoppix reads it, and not as cfdisk does?

Thanks for running a great forum...

Uh... perhaps that wasn't clear? I'll try again, just in case.

I can read and write from sdb1, sdb2, and sdb3 through Knoppix, but cfdisk tells me only sdb1 exists. If I could simply rebuild the partition table, it would save me having to archive 10-15 DVDs...

Thanks again

Read the man page for gparted and see if you think that might help.

Hi again Harry, unless I'm mistaken gparted and QTParted use the same engine. QTParted agrees with cfdisk, not knoppix. How can two partitioning programs see one thing, and knoppix the other?
