9. r/techsupport exists.
r/Datahoarder is not a sub for tech support,
r/techsupport is for posts which could have been a google search, e.g. a post with CrystalDiskInfo screenshots with the title "is my drive ok?". Literally every question about SMART status. A**udio recordings of "is this click noise normal?" More technical questions are allowed, e.g. "what is the optimal ZFS configuration of a 24 disk array" or "how else can i automate the archiving of this [thing]"
