(I'm sorry I don't have some of the error messages, I'm typing from another computer)

I recently ran emerge -avuDN world...and 60 something files were pulled in...

...upon 'finishing' it's update, a number of very strange error messages flashed across the screen...then I couldn't log into anything, it went into a read only mode...

Gentoo then tried to repair some files, it seemed like fsck commands...'error reading block 328883' stuff...

now I rebooted and get this:

Code:
[  1.88717] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,3)
[  1.887377] CPU: PID: 1 Comm: swapper/0 Not tainted 3.10.17-gentoo #1

then a few more lines then

[  1.88810] Call Trace:

then lines with question marks such as

? dump_stack
? panic+
? mount_block_root

and a blinking cursor at the end

I also cannot mount /dev/sda3 on the boot disc...

I see /dev/sda3 with
Code:
fdisk -l

and
Code:
mount /dev/sda3 /mnt/Gentoo
mount: wrong fs type, bad option, bad superblock on /dev/sda3, missing codepage or helper program, or other error
In some cases useful info is found on syslog - try dmesg | tail or so

please help!

What is the output of file -s /dev/sda? ; dmesg | tail after the mount failure you showed? What did the strange error messages say?

ok, bear in mind I'm typing all this out:

Code:
/dev/sda1: Linux rev 1.0 ext2 filesystem data, UUID=(a bunch of numbers)
/dev/sda2: Linux/i386 swap file (new style), version 1 (4K pages), size 479940 pages, no label, UUID=(more #'s)
/dev/sda3: Linux rev 1.0 ext3 filesystem data, UUID=(more #'s) (needs jounal recovery) (large files)

then some numbers, then

warning: process 'hwsetup' used the deprecated sysctl system call with 1.23.
NET: Registered protocol family 10
foredeth (#'s) no link during initialization
IPv6: ADDRCONF(NETDEV_UP): enp0s20: link is not ready
Adding 1919760k swap on /dev/sda2. Priority:-1 extents:1 across:1919760k
EXT3-fs (sda3): error: no journal found

I can fill in those #'s, but didn't think it was necessary...

ok, I looked around the internets and here's what I tried
Code:
e2fsck -p /dev/sda3
/dev/sda3: Superblock has an invalid jounal (inode8).
CLEARED.
*** ext3 journal has been deleted - filesystem is now ext2 only ***

Error reading block 17432576 (Attempt to read block from filesystem resulted in short read) while reading inode and block bitmaps.

/dev/sda3: UNEXPECTED INCONSISTENCY; FUN fsck MANUALLY.
(i.e., without -a or -p options)

so that's what I'm waiting on now...
Code:
e2fsck /dev/sda3
e2fsck 1.42.7 (21-Jan-2013)
/dev/sda3 contains a file system with errors, check forced.
Pass1: Checking inodes, blocks and sizes

Invalid journal and short reads are both bad signs. How current is your backup of that filesystem?

Yes, looks like hardware failure.
I would said your best option is stop trying to fix it, replace hdd with a sane one and fire up a livecd to try copying what could be recovered.
Fixing a dying hdd is best way to let it die for real, better keep it safe until you are ready for the operation.

thanks krinn...that was my idea...I have a usb-sata/IDE cord and I hope that I can recover my home folder...this probably is the reason that I've had these other problems that I just can't seem to solve

to answer both thread i think you need XSESSION set to the proper session, and that name change if you old use kde (by old i mean stable) or new kde (~)
to my knowledge this could be set thru ~/.xsession or /etc/env.d/somefile (gentoo suggest 90xsession, so editing /etc/env.d/90xsession)

and how you should set it depend on what kde version is running, so XSESSION="kde-4.11" (i suppose stable kde) or XSESSION="KDE-4" (i suppose for ~kde)
you can see the current state with
Code:
env | grep XSESSION

I have some real problems here...

...the XSESSION is KDE-4

...on trying to save my home folder information (especially std.vcf), I get this error
Quote:
The specified folder does not exist or was not readable.

not sure how to proceed, because I need the folder and the contents of the folder...any ideas on how to 'read' this info?

I have no idea what folder it could be, my KDE knowledge are limits to knowing kde exists.
but you should just check it exists or not, and its permissions (and owner).

I thought it might be permissions, as well, so I used
Code:
kdesu dolphin

which I think is superuser...still get the same answer, although the folder and files are there...

Still if the permissions of /home/donald or /home/donald/.kde4 aren't good, accessing/creating files in it won't be allow...

and running it root won't help your cause as you think, look at output of :
