comment /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
Sure, that will fix sudo, but it isn't going to fix the dozens of other things that were broken.

comment IO error after PSU change
Looks like your drive is broke. Boot the live cd, open the disks utility, and check the SMART health of the drive.

comment Ubuntu Server installation on SSHD
Question really doesn't make sense. If you have an SSD an an HDD, then install on those. If you have a single SSHD, then install on that.

The question is about an SSHD not an SSD + an HDD

comment Unable to Mount ext4 filesystem: bad block size 65536
You somehow formatted this filesystem using a 64k block size which is not supported on typical PCs.

comment What caused this GRUB error?
What do you mean? You already did find out what is happening: your drive is failing.

comment Disk /dev/root full, but cannot identify the reason
It isn't corrupt; you simply have files in that directory and once you mount another fs on top of it, du can no longer see those files because the other fs is in the way.

comment Disk /dev/root full, but cannot identify the reason
Are you actually running Ubuntu? That /dev/root and devtmpfs stuff doesn't show up on Ubuntu... iirc, it is older versions of redhat that do that.

comment How to clean up partitions when partition that 'does not start on physical sector boundary' is not listed in gparted?
The message appears to be a bug in fdisk since you don't have a partition 4. Partition 3 on the other hand, seems to be the one that does not start on a physical sector boundary. Since it is just an extended partition, that is fine so you can ignore it.

Ummm... no... 9 bad sectors certainly is the problem.

comment SSD & Security & wipe Oh My
Using the ATA SECURE ERASE feature ( see hdparm ) will erase everything, including the reserved erase blocks. This also leaves all erase blocks in the erased state, unlike writing zeros to all logical blocks.

Check dmesg for more detailed errors, and return it for a refund?

comment Drowning in cache
Poor responsiveness isn't caused by too much cache... if anything it is caused by too little.

comment How do I move several LVM VG's on a pair of software RAID5 arrays from one Ubuntu install to another?
Yes, Ubuntu should automatically activate any lvm volumes when you plug the disk in. You may want to add them to /etc/fstab if you want them to be mounted in specific places.

What do you mean? If you are installing the new OS on the same computer, then there is nothing to move.
