File Copying from one drive to another.

Pyrophorus2 · 2023-07-15 01:19:05

I have the journalctl output all copied to a file.

However; A couple of commands I used, seems to have copied the file over to my USB drive
When I move to this windows computer, the file is not there. I do not have internet on the affected computer.

What were these "couple of commands"? How big is / was the journal? Did you sync the filesystem and / or wait for a complete unmount?

EDIT: and how many partitions are on the USB? Does windows see / mount the proper partition(s)?

I tired with mv, cp, rsync and dd.

Results:

mv: inter-device move failed "startup.txt' to 'dev/sdc1'; unable to remove target: permission denied
cp: cannot stat '/dev/sdc1/startup.txt : Not a directory
rsync error: errors selecting input/output files, dirs (code 3) at min.c(770) [Receiver =3.2.7]

dd:
14200+1 records in
14200+1 records out
149709437 bytes (150 MB, 143 MiB) copied 4.94358 s, 30.3 MB/s

The drive is read fine on the Windows machine, but the file is not present.

Because this is not how this works at all, https://wiki.archlinux.org/title/Mount

Have you mounted the USB drive to your filesystem before cp/mv/rsync/dd?

E.g.:

mkdir /mnt/usb-drive
mount /dev/sdc1 /mnt/usb-drive
cp startup.txt /mnt/usb-drive/
umount /dev/sdc1

Your first two failed for what should be obvious reasons (see above). But the third one with `dd` appears to have been successful. However, if it was successful, this would most certainly no longer be true:

That is with a potential exception if startup.txt was smaller than any pre-partition-table gap in which case you got very lucky or perhaps if you removed the device before the data was actually flushed to it... but if `dd` in this case was successful, it'd successfully earn it's nickname of "disk destroyer". Be glad it wasn't and don't try using it again.

Whatever filesystem might have existed on sdc3 is now gone…

Im now getting

Cp: cannot create regular file '/mnt/usb-drive1/startup.txt' : Read-only filesystem

Chmod 777 has not worked

chmod is not relevant. What is the filesystem? Did you (have to) reformat after the `dd` incident? How is the device mounted?

… you want to post the output of

mount
