Just back from the holiday. I tested the media. Both hard drives are healthy. I tested to mount /mnt/toshiba. Same problem. rsync just quited and after that no files seem to be mounted. A hard restart (pulling of power) was required. Here is $sudo armbianmonitor -u Just after the restarted with the Toshiba unattached. http://ix.io/1uz5 Any help would be appreciated. Thanks, Jerry

Yep. nand-to-sata-install works pretty good.

Thank you. Yes I'll be aware. Currently, all is pure data. Yes, the media test is still on going. I'll test out /mnt/toshiba mount point once the test finished. My book is ext4. Toshiba is NTFS. Both of them are connected to USB 3.0 ports. There 4 of them on NanoPi M4. I tried all of them and got the result.

$ sudo mount /dev/sdb1 /mnt $ sudo mkdir -p /MyBackup $ sudo rsync -avh --progress /mnt/ /MyBackup/ Well as for the reason, (1) testing and (2) mainly, 3-2-1 backup. Another observation, $ sudo smartctl -x /dev/sda1 showing: SMART support is: Unavailable - device lacks SMART capability. pretty weird. I'm running $armbianmonitor -c "$HOME" to test my new 8TB MyBook now. It will take awhile but so far so good. I believe it's finishing writing >1TB; 7TB to go.

Board: Nanopi M4 with 4GB OS: Armbian_5.65_Nanopim4_Debian_stretch_default_4.4.162 Boot from SD, rootfs on an external HDD 8TB (WD MyBook). I attached another external HDD (Toshiba 2TB). I have been trying rsync -avh from the Toshiba one to the main MyBook one. It ran for under a minute before reporting files were vanished and exited with errors. It appeared the / is gone. nothing return from ls. Hard-reboot, fsck ran, everything's back to normal. I've been trying rsync with nice -n 20 as well as --bwlimit 10, 1MB. Nothing helped. stress test the board for 10 minutes, (stress -c 4 -m 4 -d 4 -i 4). All looks good. Any help's appreciated. Thanks, Jerry
