This PC has a mix of SATA & PATA HDDs: 2G for data Something with a 64G partition for OS, linux mint And an old 250G used now & then for a partial backup - other backup HDDs ar e larger.
All working well. I fit a 500G HDD from a PVR on SATA, gparted format it, k eeping it as FAT32. After this the pc won't even try to boot. Setup shows t he correct HDD is still flagged for first boot attempt, but nothing. It doe s its hardware checks, reports the HDDs then hangs.
Remove the new 500G and everything works again.
Er, what's going on?
