Dear Andryi, Thank you for your input. However: - when putting the harddrives in a different PC, the gptzfsboot: error 128 lba some_block_number changed into gptzfsboot: error 32 [if I remeber the number correctly] lba some_block_number - the same disk(s) worked in the same system without errors previously (prior version of freeNAS with less disks of the same type) - I have not been able to revert to the errorless configuration though (I think I tried all versions of freeNAS I think I could have used and seen working, with the original number of the harddrives). So I am reluctant believing the disk timeout would be the cause… Although the disks are kind of large [HGST HUH721212ALN600, 12TB] and the system is rather old (IBM x3200), and yes, the disk gave a problem ty my oldish MacPRO (macOS could see the disk only on fresh start but not on restart).... nevertheless I have specifically checked the disks worked OK in the IBM machine before ordering (more of) them and they did (initially). There is no power-up-in-standby option/toggle in the BIOS :-( Best, Peter > On 30 Jan 2020, at 18:14, Andriy Gapon <avg@FreeBSD.org> wrote: > > On 30/01/2020 16:42, Peter Rapčan wrote: >> Hi, >> >> Is there a way to tell gptzfsboot NOT to analyze other disks (or specify >> which disks to analyze)?
