October 7, 2025Oct 7 I noticed that when writing data to the array, some drives are not reading the data. Is this OK?Unraid 7.1.4. Edited October 7, 2025Oct 7 by Arnavisca
October 7, 2025Oct 7 Solution This is normal; with standard write mode, only the parity drive(s) and the drive being written to will show activity.

October 7, 2025Oct 7 Author I understand. I always had "turbo write" turned on, and then a week ago I turned on the "disk spin-down function". And if some disks are not spinning, then the write is in standard mode.My english is very bad.
