Just before trying to upgrade from F-40 to F-41, I did a back-up to a
USB 3 stick.
[snip]
But now when I insert the back-up stick into a port on either tower,
it's claimed the back-up stick is un-formatted and empty. Fedora's
"disks" and windows-10 (file browser and defender) agree.
I do not recall which file system the back-up stick was formatted with
beforehand.
How can I recover the back-up (without cost)?
Note that I'm needing to recover the back-up as a whole, not just a
file or 2 from a back-up.
How did you do the backup?
Windows doesn't like any Linux filesystems and will consider the drive
corrupted or unformatted. But it doesn't usually overwrite it unless
you say so.
This was an "incremental" back-up.
1. insert stick into port.
2. open file browser; navigate to the stick.
3. open another file browser; navigate to what I want to back up.
4. in the second file browser, select what I want to back up, and drag
it to the first file browser.
5. when the copy is done, clear cache and then do a diff to check that
it worked.
This was done weekly.
Once a back-up is 3 weeks old, it's deleted from the stick.
You can try running "gpart" on it. That will try to discover the
partitions.
# gpart /dev/sdb
Begin scan...
Possible partition(DOS FAT), size(14782mb), offset(3mb)
End scan.
Checking partitions...
Partition(DOS or Windows 95 with 32 bit FAT, LBA): primary
Ok.
Guessed primary partition table:
Primary partition(1)
type: 012(0x0C)(DOS or Windows 95 with 32 bit FAT, LBA)
size: 14782mb #s(30274944) s(8064-30283007)
chs: (3/60/1)-(1023/63/32)d (3/60/1)-(14786/39/32)r
Primary partition(2)
type: 000(0x00)(unused)
size: 0mb #s(0) s(0-0)
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r
Primary partition(3)
type: 000(0x00)(unused)
size: 0mb #s(0) s(0-0)
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r
Primary partition(4)
type: 000(0x00)(unused)
size: 0mb #s(0) s(0-0)
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r

I don't know what to make of this. The defender totally zero
everything, or are the files and directories actually out there but with
nothing pointing to them?
