I get done with my parity sync this AM and look at my cache drive in MyMain (unMenu) and it's showing HPA?.  How can this be, I'm not using a gigabyte board (asRock z87 extreme4) and it's a SanDisk 64GB drive.

 

From MyMain:

Cache Disk HPA? cache sdl Unknown 63G 5986 2,449 2,620 63G 5% 59G 33C Spinning sm hd sy sh

 

From Main Menu:

Is there a problem, or is it time to walk this to the dumpster?  Yeah, I'm PO'd, it don't make sense….

 

I notice all this after I start my parity check which won't be done until this evening.  What do I do, stop the check, turn something off,  I'm going to have my morning coffee and stew for awhile…..so much for my backup idea

 

I just changed the attributes to hpa_ok=1, I hope I did OK?  Confirm, anybody?

Are you sure it hasn't always been like that?

 

No idea how it may have acquired an HPA, but the fact is it shouldn't matter.  As long as all's working well, the small amount the HPA "eats" isn't a big deal.    It's not even clear that it's actually an HPA ... JoeL can comment on how MyMain shows that, but I'm not sure why there's a "?" after the HPA indication -- might just be some status difference with an SSD that's causing an anomaly in the display.

 

In any event, as long as all's working well otherwise, I wouldn't worry about it.  And this shouldn't have any bearing at all on your backup plans 

... by the way, r.e. backups => here's some backup storage for $33.33/TB !!
