My venerable QNAP TS-251-4G (from 2015) seems to have given up the ghost. I just want to double-check with the wisdom of the community whether that is the case, and if so what to do next (e.g. suitable replacement chassis that will take my two 3TB WD Red SATA drives with existing mostly home video/p…

Migration Path [image] Compatibility for NAS Migration - QNAP Check compatibility for migrating hard drives from one QNAP NAS to another. LPC Death (a google search on that will turn up a few other links as well) https://forum.qnap.com/viewtopic.php?t=15745…

Sounds like the LPC death..often asked ..often answered https://forum.qnap.com/viewtopic.php?t=157459 https://forum.qnap.com/viewtopic.php?t=135089

Thanks both for confirming the symptoms. So I understand (per the migration page) that my QTS cannot migrate to NAS running QuTS hero safely. So I need a system running QTS. Meanwhile, according to the migration tool, my TS-251 can’t migrate to TS-216G or TS-233 directly (it talks about backing up…

[image] bluemeerkat: it talks about backing up, which is not an option with my bricked TS-251 Backups need to be done !!before!! stuff breaks or is deleted…if you ever get your data back, start doing backups, it will save you lots of tears and/or money

Thanks for the info about QTS folks. Will also look into RAID5 and 4 bay options. dolbyman… sorry I wasn’t clearer. The reference to backups from the migration tool was as follows when I specified source of TS-251 and destination of TS-233 or TS-216G:: ”Your source NAS does not support direct migr…

[image] bluemeerkat: those two drives back-up each other for starters well..internal backups are a bad idea, as you can see in your case. But cloud backups are a good idea for the worst case. I wonder how much the retrieval costs are, an external backup HDD might still be worth it

dolbyman - All fair points. Am considering a WD Elements USB drive or equivalent. I did dig out an old SATA hard drive dock this morning, but I’ve changed laptop since last using it, and don’t have an eSATA port to access that dock any more (but I’ll order a new eSATA to USB-C cable).

When I purchased my TS-264, it came with QTS.
