The operation can’t be completed because an unexpected error occurred (error code -50)

I had been transfering data from my macbook to my EX2 (and back) successfully for months. In january I started getting this error message (The operation can’t be completed because an unexpected error occurred (error code -50).). I can’t transfer to the EX2, and I can’t delete anything from the EX2 with my macbook.

I need helped! Not sure if it is a problem with the EX2 or my laptop, I am hoping someone can point me in the right direction.

first check the dashboard if any alert or color orientiation to disk issues.

It could be any issues. Did you tried rebooting the NAS and try again.

What was the setup you have RAID 0 or 1 or JBOD.

How much storage left . What file you are trying to copy. Some times file naming convention can be a problem.

Give more details and will figure out the issues.

No alerts. Says everything is fine. I tried rebooting and it did not help. It’s set to RAID 1. 1.45 TB free.

I use the NAS to back up my work files, so I am trying to copy many files at the same time.

Way back I used to use WD sync but it was unreliable so now I backup manually.
