[PLUG] Boot failure
Yesterday morning I started my Ubuntu 14.04 desktop system only to be presented with "Busybox V1.21.1 (ubuntu 1:1.21.0 1ubuntu1) builtin shell (ash) initramfs Entering "exit" just returned the same "Busybox..." Power off then power back on presented a screen which seemed to present various startup options. (No good notes at this point.) While trying to digest the options it got tired of waiting it booted. Everything has been normal since then. Is it possible that I hit a key during the first startup that triggered the "Busybox ..."? I was a bit distracted, so that is possible. If such a cause is not likely, what might this message be a harbinger of? Thanks, -Denis ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Abrasion bad ;) Back in the 60's I was an electronics tech in a university's chemistry department - think nasty environment for electronics. My boss had a solution (pun intended) to the problem - during routine maintenance we applied a mixture of De-oxid(TM) and watch oil to connectors and switch contacts (particular open style rotary switches). His rational for adding the watch oil to the De-oxid (advertised as a lubricant as well as cleaner) was that the watch oil helped form a mechanical barrier to the atmosphere at the actual point of electrical connection. I found http://de-oxid.com/. They appear to have tweaked the formula, added a hyphen to the product name, and changed the label color in last half century.

I use a lot of those, but they are cheaply made. Connectors have limited lifetimes, because the copper diffuses into the thin gold plating on it. Then the copper oxidizes, making insulating spots, and making the surface much less compliant, with less contact area. You can clean the contact a couple of times with a pencil eraser, but if the gold is thin (on the Kingwin docks, it may be just a few atoms thick), and it will get worn away. It would be nice to find a more expensive drive dock with thicker gold plating. It would also be nice if test labs would measure this stuff and publish results in something like what Consumer Reports used to be, before they devolved into knob counting and political opinions.

This a SATA hard drive dock which mounts in an ATX case. It is a Kingwin KF-1000 BK. When I get a blank panel to fill the hole I will take it out and look it over. I am surprised that there is anything to go wrong inside except connectors. On Mon, Nov 9, 2015 at 9:45 PM, Wayne E. Van Loon Sr. wrote: > Yea, I've had it happen.

[PLUG] boot failure
Thanks for all the ideas and suggestions. I ran for two days on a CD, then tried again to boot from the HD. One time it worked fine, then it failed with the same error ( error: attempt to read or write outside of disk 'hd0'. Entering rescue mode. grub rescue>). The next time I tried with the CD, it could not access the HD. I tried my old HD with the CD. It could not be accessed either. So I took it to the local shop (Portland Support, 3150 SW 87th Av. Portland). He suspected the HD dock, since he often observes problems with them. Yes, that is what it was. He stuck the drive inside, and now everything is fine. $45, minimum charge. Competent, fast, genuinely nice guy. Some of you may recall that I had some suspicions of a HD problem in late July. I replaced the drive and had no problems until this issue. I suspect that July problem was not the drive, but the dock. So now it is likely that I have a good spare drive. -Denis ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
Re: [PLUG] boot failure
Yes, power off was used to recover from a freeze recently. I noticed in some google responses that BIOS restrictions on HD size could cause this. My upgrade in august was from 500G to 1T.

Re: [PLUG] boot failure
The "attempt to read/write outside of 'hd0'" message has me thinking your Grub installation was/is bad. Maybe a fresh "grub2-install" will fix it? I was wondering about the partition table, but if fsck(8) was able to scan/fix the partition(s), then the partition table data is probably OK. The corrupt data in the 'sda1' filesystem isn't good. Do you suspect that power was simply yanked from it at one point? Is there any other reason why the data on your disk might be corrupt?

Re: [PLUG] boot failure
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.)

Re: [PLUG] boot failure
Denis, Be sure you ran the system with the CD 12.04 for awhile, and you used the system as you normally use it. If you have a heat problem, you need to exercise your system as much as possible to see if the problem reappears. You can run diagnostics on your hard drive from the CD to see if you have a HD problem. Someone on the list will know more about disk utilities on your CD than I do. If there is no heat issue and no HD issues, then you may have been hacked. Mark On Wed, Nov 4, 2015 at 2:21 PM, Denis Heidtmann wrote: > Now there is something I can do. CD 12.04 seems to run fine.

Re: [PLUG] boot failure
Now there is something I can do. CD 12.04 seems to run fine. So you would point to SW. How about the HD? Is there a chance that an intruder mucked things up? Our system is not on line all the time--only when it is use. What to do next? Thanks so much.

Re: [PLUG] boot failure
I want to add something here in case it helps. I had emailed PLUG when I had an issue with my computer as well. It's an old MacBook. I ended up going with this solution after doing some research and experimentation: 1. I created a bootable thumb drive with an Ubuntu on it. 2. I accessed the grub menu by pressing the 'alt/option' key during startup. 3. I selected 'Ubuntu Advanced options'. 4. I pressed 'e' to make edits. But instead of making edits, I pressed 'F2' to get the grub terminal. 5. On the terminal I entered these 3 lines: (1) set root=(hd1), (2) chainloader +1, and (3) boot. By following these steps I was able to reinstall Ubuntu from the thumbdrive. Note: I did not salvage any files with this process. I just wanted to completely wipe all files and reinstall Ubuntu.

Re: [PLUG] boot failure
A live cd or live usb stick running properly would tell u your issue is software. If it locks up too heat or power supply could be the culprit.

Re: [PLUG] boot failure
So what to do? I found references on the web in responses to the 'grub rescue>' prompt that said 'set' and 'ls' were useful, so: ls: (hd0) (hd0,msdos5) (hd0,msdos1) (fd0) set: cmdpath=(hd0) prefix=(hd0,msdos1)/boot/grub root=hd0,msdos1 Does this help at all? -Denis On Wed, Nov 4, 2015 at 9:19 AM, benjamin barber wrote: > it sounds more like intrusion than hardware failure. > > On Wed, Nov 4, 2015 at 9:11 AM, Denis Heidtmann > > wrote: > > > The precursor may or may not be related. > > > > I discovered that my wife's gmail had been accessed by an iphone on Nov, > > 1.

Re: [PLUG] boot failure
it sounds more like intrusion than hardware failure.

[PLUG] boot failure
The precursor may or may not be related. I discovered that my wife's gmail had been accessed by an iphone on Nov, 1. We have no iphone, and were home alone at the time listed. So I changed the pass word. Then tried to open firefox. Would not load. Nothing would work, except the mouse pointer would move around. Had to use the power button to restart. Now I get error: attempt to read or write outside of disk 'hd0'. Entering rescue mode. grub rescue> Yesterday the computer froze in a similar fashion when my wife was looking at email in evolution. A power switch intervention was required, but it booted fine at that time. So the two incidents point to hardware problems or intrusion? I have googled for grub rescue recovery, but what I found was aimed at people with more understanding than I have. Are there suggestions that someone here can offer? thanks, -Denis ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
