Thanks for the help @Bennor

“Why would you “loose” the option to update to OS5 if your My Cloud supports being updated to OS5?”
Misread the e-mail from WD. I thought ht free upgrade would end 15thjanuary, now I see is only the support and web access.
“As a troubleshooting step. If you connect the WD MyBook drive directly to a computer and try copying files directly to it from the computer does the file copy fail similar to how it fails when connected directly to the My Cloud?”
One of my first tries but very, very, very slow and also a few fails from what I recall. If I cannot do it while connected to the MyCloud directly I will go back to this.
"Some hard drives will spin down when they think they are not being used. Sometimes one can configure that spin down/sleep setting on external USB hard drives. Check the support for your MyBook drive to see if it supports the option to configure the sleep setting and if so, how to change it. "
One of my checks but I couldn’t find a way to do it yet. Although, the errors appear to be on the read phase @ MyCloud, not on the write phase at the USB Disk.
“My Cloud also includes an option for “sleep” in the My Cloud Dashboard Settings, one can disable that as a troubleshooting step to see if backups continue.”
Yes, disable that also.
“Other troubleshooting steps. Check the MyBook drive to ensure it’s not failing or has bad sectors.”
I’ve had a few warnings in the past and after recovery (blinking red) and test they are gone from the dashboard Logs. This is reason onefor removing all the data from the disk that I can.
“Try a different cable with the MyBook.”
Tried with a few also.
“Export the My Cloud logs (using the My Cloud Dashboard Help section) and see if the logs show any sort of errors or causes.”
Will get into that also.
“Try using SSH to copy files from the My Cloud to the MyBook using Rsync.”
This is for now out of my knowledge.
“On a side note. Sometimes files with special characters/foreign letter characters in the name can cause copy programs to fail. Check your file names just to be sure.”
That was one of the problems with Robocopy. I solved it, but I kept loosing connection midway.
“As a worst case scenario one may have to copy large amounts of files in batches to see if the backup fails with one specific set of files, then work through that batch of files to find the offending file”
Thanks. That is what I’m trying to do.
I believe I may have a few bad sectors and a a few files with errors. But I’m also getting connection errors out of nowhere. Now I’m trying teracopy with twitch for WIN 10 Registry found on their community support forum for copy within WIN 10 and NAS between mapped drives that keeps the connection alive somehow.
Doing a test right now with TeraCopy a folder with circa 300GB of avi and Mkv files, but also a lot of word/excel/PPT/PDF files of small size. An estimated 6h to complete…
I’m getting a few connection warnings but the copy is apparently recovering and moving on instead of collapsing.
I will give feedback on that after conclusion of this test.
Thanks again.

PS I didn’t get how to quote you properly on this editor, sorry…
I found out that the sleep mode was On in MyCloud (must forgot to disable it after last recovery…) . But after turning it off again I could not disable also the web timeout. It’s maxed at 30 min, but I don’t know if it has any relevance on copying trough map drive connections on TeraCopy.
