HDD (5) not format to gpt

[luca63]

Good morning everyone.I have a big problem, I am trying to format 5 HDs and then create a container for saving data.My problem is that I can only see one HD at a time without being able to make pools.The strange thing is that I can initialise maybe 3 of them with GPT and then one disappears not giving me the possibility to create a pool. What could it be?

Maybe a power issue, where the 5V or 12V line drops too low when a few drives are active? Did those drives in that system work fine before or did you recently install them? It could also be memory corruption. Anything relevant in journalctl (use the arrow keys to scroll to the time of the issues)?

yes now that you have given me a doubt it could indeed be power failure, when there were 3 HDs they worked perfectly, now I will try with 4

well miraculously 4 HDs have come to light, it means I only use those or another method of cloud
