Hello Bbsing!
15 Aug 19 20:39, you wrote to me:

Never had that happen with USB thumb drives... but heat is bad for any
electronics period.

Standard USB external HD (not a SSD! I don't use or trust that garbage)

I can SEE THE PARTIOTION in test disk... it just comes up with the Message
"Can't mount drive.... " if I plug it in and try to access it like normal use.

This is why I don't use SSD unreliable and write limited.

Caveat, I don't use any thingBUT LINUX. OK, Z/vm, z/os, s3xx, :) ;) :) but
other crap? nope. :)

dd is too dangerous for use for exactly #1, and #2.

What info for real drives? ie:
9339387.713615] usb 1-3: USB disconnect, device number 6
[9339387.714581] sd 7:0:0:0: [sdb] Synchronizing SCSI cache
[9339387.714706] sd 7:0:0:0: [sdb] Result: hostbyte=DID_NO_CONNECT
driverbyte=DRIVER_OK
[9339395.976052] usb 1-3: new high-speed USB device number 10 using ehci_hcd
[9339396.186116] scsi8 : usb-storage 1-3:1.0
[9339397.184886] scsi 8:0:0:0: Direct-Access Seagate BUP BK
0109 PQ: 0 ANSI: 6
[9339397.186602] sd 8:0:0:0: Attached scsi generic sg1 type 0
I guess I am more interested in:
1) What acn be done via testdisk to use its internal backup/recovery
options.... BEFORE I DO
2) Reset the info, likely the partition info, so that plugging it in and
selecing to open in file manager or mounting it other ways works
I have HUGE RISK AVERSION. Meaning that measure 40x then review, measure 50x
more, review.. backup backup backup.. try it...
So I'd like to use testdisk to suck out the data I can to say either another
4TB drive I attach to the box and then I can review what I've recovered and go
from there.. then test out the steps to recover the disk.. ie: do the x,y,z in
testdisk to reset it and then see if it is mountable...
I just can seem to find a GOOD STEP BY STEP EXPLAIN it in full for testdisk ,
that after I am at the point, below, do, x,y,z to reset things so the drive is
mountable...
Here is some info from testdisk... I have a box with 7.xx testdisk, but where
this golded is at is another box, and I quickly attached and ran this to see
... Which based on looking via the testdisk file browser the STUFF IS STILL
THERE, the partition table is fubar'd and needs to be reset????
