External NTFS HDD Power Issues / Disconnects

ah, how would i go about that using dd? i'm not super confident with the command

seth · Yesterday 21:27:40

cd /path/to/disk/art/lotsofpictures
for name in *; do dd if="$name" iflag=sync,nocache of=/dev/null &; done

This reads all files there and "copies" them into /dev/null
The ampersand will fire off all dd jobs in parallel, that should take the wind out of the bus.

was about to try this and the disk just disconnected on it's own. nothing even really triggered it this time.

at this point i have given up, i think it's just busted. a replacement from amazon is on the way, i will likely just format it to ext4 and use it as storage for my games, and other important stuff will go on a usb with NTFS. unless we can figure something out by tomorrow but i doubt it.

The journal also shows a (failing) umount? Do you use x-systemd.idle-timeout ?

Does the drive (and cable) act stable on a different host or w/ a live system like https://grml.org/?

We can stil figure what's wrong - I still don't think the filesystem will help you here.

I believe it works fine on windows, but haven't tested it much. I'm not sure if i use idle-timeout but i could try disabling it.

Any idea what else might have unmounted the drive at that point?

levalithan · Yesterday 23:47:57

My only guess is maybe it tries to unmount the drive when it fails the sync, but beyond that I have no idea. I'm starting to suspect the hardware is at fault
