Thanks for the information. I have been running the system on the dvd for a number of hours without incident. I just ran sudo fsck.ext4 -fv /dev/sda1. There were a number of errors, but nothing which looked very serious to me. (All errors corrected.) I should have captured the reports to a file, but instead I took two photos. Errors were inodes part of a corrupted linked list, inode w/zero dtime, block bitmap differences, free blocks count wrong, inode bitmap differences, free inodes count wrong. There were no bad blocks. If the details are important I expect I can get the photos up.
I should point out that this HD is new as of August, as is the OS (ubuntu 14.04 replacing 12.04). Assuming I have been hacked, how do I recover? (I have not tried to reboot since running fsck.) Thanks again for your advice. -Denis On Thu, Nov 5, 2015 at 2:20 AM, Mark Phillips <m...@phillipsmarketing.biz> wrote: > Denis, > > Be sure you ran the system with the CD 12.04 for awhile, and you used the > system as you normally use it.
