read errors from the larger disk: Re: Re Request for help Was: BerkeleyLUG (website): Removing spambot Users - User action needed ...
ddrescue(1) could be handy.
If you've 2TB drive, to (attempt to) recover that, you'll want at minimum
drive/device/volume that is at least moderately larger than that ...
preferably up to about twice as large or larger in total capacity.
... plus whatever you want to backup additional drive(s).
Once you've got image copy of the disk (or as much as feasible),
can then work ... not directly on that - but a (virtual) copy of
that, as needed/desired, to (attempt to) recover further - as feasible.
You can do read-only operations on the original as feasible to see what
can/can't be read ... but it might not all matter - if it's not used
space, you may not care. Depending on the extent to which it's (partially)
readable, stuff like find and cat can be useful.
Also, ... "virtual" copy - could be a copy-on-write - so rather than
double space yet again, only increase actual space used by what's
As for read-only, don't merely mount ro - that won't fully suffice,
as mount may change things upon mount or attempt thereof - even if ro
is specified on the mount. You can use blockdev(8) to set the devices
themselves (e.g. drive & all its partitions).

You were off topic. Next time compose a new email to
Anyways. There is a meeting this Sunday at the blue door Cafe from 11 to 2.
You are welcome to bring the machine.
But I have to say that data recovery is unlikely. If the OS can't see the
drive then no commands can act on it. That said there are some tricks to
get the drive to work a short while and data recovery is possible in that
But bring the machine and some new drives and we can help you to reinstall

my apologiez for that but here is my question
I'm on a System76 laptop. It has a 250GB SSD and a 2TB Spinning Disk.
My backup hygiene is less than perfect.
I'd gotten read errors from the larger disk in a few directories. I
decided to reboot.
I then didn't even see the secondb larger hard drive as a device (no
I then decided to fully power it down, and start it up.
I am hearing an internal whirring/beeping(?) sound when the computer
starts, and the disk light stays on. I get some ASCII art startup screen
that looks like it's from the BIOS, and starting Ubuntu fails.
I would like:
1) A backup of both disks, as much as recoverable. I can provide a 4TB
removable drive with enough free space.
2) A box that boots to Linux again.

BerkeleyLUG (website): Removing spambot Users
If you are a registered User on the web site (https://berkeleylug.com/)
you may want to pay attention to the above posting. We'll be removing
(suspected) spambot accounts bit over a month from now.
In relevant part you may particularly want to pay attention to:
User action needed / how do I avoid getting my User account removed
along with the spambot accounts?:
o Looks like the spambots can't be bothered to set a First Name and/or
Last Name on the profile of their account, so set a non-blank
First Name and/or Last Name on your Profile Personal Options.
o Be or become a subscriber to our BerkeleyLUG list (Google Groups).
For all email addresses subscribed to that list, for Users Registered
on our BerkeleyLUG web site where we have a matched email address,
we'll presume that user isn't a spambot and won't remove that
registered User account in our spambot purging efforts (be sure your
email addresses match - do you need to change/update for them to
o Be grandfathered in (only applies to a very small number of Users) -
if your account was already on the site before we migrated hosting
(your account was created before 2019-08-30), we'll consider you
grandfathered in and not a spambot - that's only these Username
