My imac g5 20 inch Isight after putting a samsung 850 EVO SATA ssd that I had in the pc no longer gave me problems and has a very GOOD speed and silence under morphos it has been mounted for 6 months considering it is already at least 5 years old and many hours of on and constant use from 10 hours a day on
I'm practically done with the 3.5-inch hard drives with many years of age and rotation of the disks
sooner or later they jump and better not use them anymore this kind of discs

Amigaharry2 - it's a PowerMac G5. The HDD does not spin down. I can see the contents of the HDD just fine from within OperFirmware, the boot command actually loads the boot image from the SATA disk itself but it will either start without seeing anything SATA or just crash if I use any other command line. It's a bug, not a feature :)

Have not tried another HDD, those are original Apple-branded ones with their firmware.

I know, it's a PM G5 - I have the same modell as described earlier - and with exact the same problem. Therefore I asked.
I think it's a timing-problem ( and no matter whether this HD is apple-branded or not).

Meanwhile I changed HDD on this G5 and it works normal again - no need fo edebugflags any more....
