May 12, 201214 yr I just finally added a cache drive to my system and unmenu shows HPA? Says set drive hpa_ok attribute to 1 to ignore. the drive is a 150Gb velociraptor drive so I dont know if that has anything to do with it or not. User Capacity: 150,039,945,216 bytes On the unraid main menu it lists, 146,523,352 All my drives end in 552, but this one obviously does not, so I guess HPA is possible
May 12, 201214 yr The 552 thing is only above a certain size, I don't remember exactly what size, but it's quite a bit bigger than 150GB. It may be 750GB or 1TB. I wouldn't really worry about it on a non protected disk. The main concern is that you know how the HPA got there, if it was from another system entirely, no worries. If your unRaid system is randomly HPA'ing disks, it could cause havoc if it touches an array disk.

May 12, 201214 yr Author /dev/sdg: max sectors = 293046768/7834096(293046768?), HPA setting seems invalid (buggy kernel device driver?)
May 17, 201214 yr Joe, any thoughts on this? Ignore the warning. As indicated by hdparm, the reported size by the kernel is suspect. Joe L.
