HPA Detected - What's it mean?

Featured Replies

Hi Guys,

 

First, thanks to everyone for their help troubleshooting the previously reported issue I was having after upgrading. Replaced the SATA cable and the problem seems resolved.

 

Looking at my syslog, I see the following:

 

Oct 21 12:54:32 Tower kernel: ata1.00: HPA detected: current 1677721620, native 2000409264

 

Not sure what HPA detected refers to. Full diagnostics are attached.

 

Thanks again for everyone's help!

Your SSD is not using all available space.

If I don't care about the lost space -- this is my cache drive -- is there any need to worry/take action?

HPA is only a real big deal if its on the parity drive.  Additionally, if the motherboard placed the HPA partitition on the cache drive, then as a general rule, it will not place HPA onto any other drive, so in that case its actually a decent idea to leave the HPA on the drive to prevent it from going on anything else

I didn't realise HPA was still a thing, I remember it being an issue with Gigabyte boards back in the day.  Never realised it still happened.

This drive was purchased from Amazon and labeled as Incorrectly Provisioned - discounted. So I think that's the problem. I don't think the OS caused the problem. I'm using a highly recommended MOBO, new, I just can't remember the model off the top of my head

Good to know! Thanks

Sounds like a better explanation.  It used to be some Gigabyte models caused issues back in 2011 - 2012 I think.  But I haven't heard anybody with issues for years.

WAG, Since were talking about a SSD, maybe the manufacturer is using HPA for housekeeping? <shrug?>

I like to keep everyone on their toes
