Mounting an additional hard drive, guide question

I am adding an additional hard drive following this guide which uses gparted. https://help.ubuntu.com/community/InstallingANewHardDrive

However there is a line of code which I dont understand (sorry I am very much a beginner):

  /dev/sdb1    /media/mynewdrive   ext3    defaults     0        2 

Specifically I want to know if using /dev/sdb1 is generic and not particular to the person who made the guide and what are the 0 2 for? I want to make sure that this does not alter anything that I currently have.

Is it possible and how to clone Ubuntu and Windows 10 OS’s into one big drive?

I have an existing Ubuntu 18.04 installation in one drive and Windows 10 in another. I’d like to have them both without reinstalling in one big drive separated by partitions. How can I do that? Simply using dd to clone to each? how about dual boot with grub? How do I ensure that it works?

Taking a guess I would clone first Ubuntu into that huge drive and later accommodate additional partitions for the Windows 10 & 7 installations. Then run grub-update and/or boot-repair.

Any suggestions?

PS: the “big drive” is an Adaptec 8850 holding 4x 1TB SSD’s in RAID-0 which should give all these OS’s a huge IO boost I presume.

Booting Windows from external Hard Drive?

I have searched the whole forum and couldn’t find anyone having the same problem with all the specifics in mind.

My laptop uses Linux exclusively. I wanted to have an option to run Windows every now and then, so I have installed Windows on my external SSD. Before installing I have switched drives and inserted an empty brand new SSD in place of my hard drive with Linux. I have installed Windows 10 (legal copy from Microsoft website with no key) on that drive and everything was working fine until I removed the SSD from my laptop and tried to boot it as an external hard drive. It troubleshoots my PC, eventually giving me an option to restart the computer. After restarting exactly the same thing.

Read Only problems with shared Data Drive after Win 10 upgrade

I have Win 10, UbuntuMate, and Deepin plus a partition called Data on my machine.

I recently upgraded Win 10 because it asked me to. Now I cannot access my Data drive with write permission on Linux OS’s on my machine.

To test whether anything I did was successful, I right click in Caja and see if I can create a folder.. NOPE..it is grey

I have tried:

shift + shutdown (Usually works for c-drive r+w problems)

Changing permissions to full control in Windows

Changing sharing to everyone in Windows

How can I restore DVD drive operation following recent Ubuntu r10.04 `apt upgrade`

Some time in the last day or two, following one of the recent apt update-s the DVD driver on my desktop has stopped working.

  • between: 2019-09-15 (UTC) or so
  • until: 2019-09-20 (UTC)

After several unsuccessful attempts to understand what happened, I have backtracked a few steps and decided what I need to do ‘work forward from here‘ and restore the DVD and replay operations.

Here’s my thinking:

  • The player should work (it can work)
    • I did work prior to what ever has changed in the software.
  • By restoring function, not only will I learn something about that kind of thing, it may help others get past this kind of issue.
    • I have seen earlier problems back with Ubunty 14 and 16 that look similar on stackoverflow/askubntu.
  • What ever has happened looks very largely like a regression
    • Nothing has changed in the drive or hardware itself.
    • And the ‘target’ DVD I chose is one that played fine 8 or 9 days ago.
  • If I need to back-out a package or update, so be it. The best way to findout what it is is to identify today’s problem.

Symptoms

My layman’s view of the problem is that for some reason applications cannot read the DVD content. dvdbackup for example reported that ti cannot find titles. Handbrake and handbrakeCLI have similar issues. They try to read but the interpretation is unintelligible.

Same with VLC no doubt as it just ties and tries and displays a black screen — Nothing happens. There are reports of scrambled cells and I/O errors.

You might think a DVD is corrupt. That’s why I picked one I viewed successfully in the recent past.

My aim is to look at what I’d do with a new DVD drive installed.

  • What steps would I follow to get a new DVD working?
  • What installation errors and problems are showing up now?
  • To resolve them if that’s practical / feasible.
    • Back out a package or ammeliorate things with alternative or supporting packages that may be not-yet-delivered/installed.

I hope you can help. Here is the delta between a “before” and “now” scenario where I did a domestic reset and had a cup of tea.

I don’t know if the dmesg people read these questions, but I’d very much prefer it if dmesg output showed the local time so I have a better idea of what is happening and where that was on the time line. Looking forward to your insights.

Delta experiment …

What do we know?

Tonight …

  1. I took down a Harry Potter DVD that has played on this PC before (some time last week actually).
    • The result is that VLC just shuffles a bit and gives up.
  2. So then unloaded the DVD
  3. Ran dmesg > tmp.01
    • to get the “baseline”
  4. Reloaded the DVD into the drive
  5. Used the VLC “Play disk” Media menu option
  6. Allowed the DVD player shuffle and grunt
  7. Once that’s done, ran dmesg > tmp.02 again.
  8. took a delta (with diff) as shown

I apologise for pasting so much here. I am not clear on what’s important and what is just a repeats of the same errors.

Unable to install Ubuntu server LTS via USB drive


View post on imgur.com

Errors received shown above. I’m not exactly sure what they mean or if they can actually be fixed (is a hardware problem a real possibility?) So far I have:

  1. Reset CMOS
  2. Tried every USB port on my mobo
  3. Reinstalled iso on thumbdrive multiple times
  4. Disabled USB 3.0 in BIOS
  5. Installed ubuntu on a different computer and moved the drive to this one. This did work and ubuntu technically ran but there were other errors that I couldn’t seem to fix (for starters eth0 wouldn’t show up)

Potential solution (that I will try tomorrow):

After further research, it seems that there is a quirk with Gigabyte motherboards. I will use a 4gb partition and enable IOMMU as highlighted here: Dual Boot Ubuntu 14.04 with Windows 7 on UEFI

If this solution fixes my issue I’ll delete this question tomorrow.

mounting an old raid external hard drive

New to the group. I have an old MyBook external, networked hard drive that windows could not connect to. I removed the hard drive and threw everything else away (should not have done) thinking I would just connect it as an external hard drive. I then figured out that is was a raid drive with a linux file system and it would not boot to the windows machine. I have a an Ubuntu machine that will not auto detect the drive. I can see it using the gnome drive tool or through the terminal. All of our digital pictures are on this drive so I do want to lose it.

Can this be mounted manually without damaging the drive?

Id of each file is generated as 33 characters and contains non-alphabetic characters.

=> Is it possible to compress it into 32 characters using base decoding.

I realize that all Id of listed each file starts with 1. So could I assume this pattern on the creation of the Id, where all of them starts with 1 and could I discard the 1 at the beginning.
