@Kevin_Z I don't understand, I put the picture, USB - HDD HIBERNATION - TIME - 300 SECOND, sda and sdb are SSD, sdc and sde are HDD and go to sleep after 300 seconds, this is on ASUS ROUTER

@cata2k2k I have an asuss router and it supports this !

Hello, I recently bought an AX20 router and I have the following problem, I tried several HDDs on USB, it works perfectly but the problem is that none enters standby this leading to premature wear...
