galen,

  Looks like drives sold in external USB enclosures do have different
firmware on the drives. As a response on that thread wrote, "There have been
several posts about this type of problem in the past on this forum. The
usual culprit is a USB drive enclosure that has a 32-bit limitation. ...
I've never heard of this problem showing up in Linux with internal drives,

  So I guess it's now a 750G drive since it started life as an external
drive and I intended it to remain so, but in a multi-drive bay.

galen,

  I used parted -l /dev/sdc. The tool showed all three disks; it reported sdc
having 802G capacity. parted /dev/sdc print reports the same 802G.

  Seems like this drive just will not allow access to the full 3T when
outside of its original case. Perhaps Seagate builds the firmware
differently when the drive is sold in an external enclosure rather than for
internal use in a desktop.

  So, since we seem to have exhausted possibilities (fdisk, cfdisk, lsblk,
parted, gparted) I need to replace it with a known-good internal hard drive.
Will order from Newegg later today.

Re: [PLUG] Mounting USB flash drive

[John Jason Jordan]

Also, I find it is better to give the partition a label with gparted
and then use the label in fstab rather than /dev/sd??.Not only does
this eliminate confusing fstab as to which device to mount, but it also
means that my label is what appears in the GUI file manager, so I am
also less likely to be confused, e.g.:

 /mnt/flash vfat auto,user,rw 0 0

[PLUG] rsync: worked once now perms error

[Rich Shepard]

  Yesterday rsync copied ~/ from the current desktop (salmo) to the new
desktop (baetis) using this command from ~/ on the new desktop: rsync -av
salmo: .

  /opt on both hosts have perms 777.

  However, when I try to copy the /opt partition from salmo to baetis I get
a permission denied (publickey) error. Running 'ssh -vv salmo' from the new
desktop shows sending and receiving packets with no issues until this:

debug2: service_accept: ssh-userauth
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: publickey
debug1: Next authentication method: publickey

debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
Permission denied (publickey).

  Line 5 looks to be trying to send the private key rather than the public

  Here's what I checked:

  1. Perms for both hosts' .ssh/ are 644 except for the private keys for
which it is 600.
  2. Both hosts have the other host's public key in ~/.ssh/authorized_keys.
  3. Both hosts have the other host recognized in ~/.ssh/known_hosts.
  4. From salmo I can successfully connect to baetis,

  Since rsync worked on baetis yesterday to copy my home directory from
salmo I'm not seeing why today it will not copy /opt. And web searches
(almost all from ubuntu and github users) offered nothing different from
what I checked.

  A clue stick will help.

  In /etc/fstab is this entry:
/dev/sdc1  /mnt/flash   vfat  auto,users,rw  0   0

  When I try to mount it as a user the system tells me that only root can
mount /dev/sdc1 on /mnt/flash. What might cause this response?

[PLUG] Wanted: handheld data collection device with Linux OS

[Richard Owlett]

I'm looking for a current production Linux handheld data collection 
device {aka PDA} similar in form and function to a Palm Pilot 
(https://en.wikipedia.org/wiki/PalmPilot).


A major justification of Linux OS is to allow custom software.

Specification:
  be currently available from U.S. retail vendor.
  have a physical form factor similar to a Palm Pilot
  should have provision for using a USB/Bluetooth connected keyboard.
  be able to read/write a USB flash drive (preferably FAT32 or ext2).
  *no* cell network connectivity .
  must *NOT* be shipped with Android OS

Yes, this thread resembles one from a year ago.
I'm renewing by search first done a decade ago.
I kick myself for not having purchased a Palm Pilot back in the day.

My web searches have turned up "we're working on it" type answers and 
crowdfunding appeals.


Any suggestions other than putting up with a smartphone?
TIA
