The following partitions/data were probably from a couple years back when I was experimenting around, but have too much stuff spread out over too many devices so trying to start consolidating/organizing.
PC #1 - pclos 2012 KDE on a custom whitebox. 80 gb HD (sda) in master position setup as /, swap, /home (sda1,swap, sda5) respectively
PC #2 - pclos 2009.1 KDE 3.5.x on another custom whitebox. new WD 320gb in master position setup as /,swap, /home, /?, /repos (sdb1 (pclos), sdb7 (/home), sdb8 ( I have no idea why I created it but it does have some personal files on it), sdb6 (repos) respectively
Pulled 320gb HD from PC#2 and put into slave position in PC #1 to use as a temp backup and of course this drive is now seen as sdb ( sdb7 is about 250 gb free space). The 4 partitions of 320gb HD were mounted by PC#1 under /media as disk, disk-1, disk-2, disk-3
PC #2 is no longer.
Have decided I don't need 320gb drive as backup in PC#1 running all the time so pulled it and connected it via USB to daily driver laptop logged in as user01 and it showed up in Dolphin as disk, disk-1, disk-2, disk-3, all read only.
I just needed stuff off sdb7 (disk-3) and noticed it was owned by root although the subdirectories were owned by user01 ( I have several PC/laptops and of course use the same username). Could not transfer these files from 320 drive to lappy so I thought if I:
chown -R user01:user01 disk-3 all would be well, but even as root, console returned that this was all read only.
So returned 320gb drive to PC#1 in slave position and all partitions EXCEPT the one I tinkered ( sdb7) with are visible in Dolphin and/or console.
Accessing sdb from PCC disk management when 320gb drive is installed in PC#1 shows sdb7 and am able to mount and view contents but only in the PCC partition viewer. sdb7 no longer visible in either Dolphin or mountable via console in PC#1. error is "can't find /dev/sdb7 in /etc/fstab or /etc/mtab" . These partitions never were listed in fstab before.
What did I screw up and how to get access to data on partition sdb7?
