March 13, 201313 yr I just finished installing a 4 TB parity drive, replacing a 2 TB drive and rebuilding parity. My main screen reports that the drive is 3907018532 bytes. That sounds reasonable, but I'm getting a strange message on the mymain screen of unmenu which seems to think that I might have HPA on the drive. (see attached image.) I am almost certain that I don't (HPA is disabled in my BIOS and I can find no reference to it in my syslog), but I'm reluctant to proceed until I know this is some sort of artifact since mymain was programmed during an era of 2 TB drives. If 3907018532 is the correct number of bytes that unraid reports for 4 TB drives then there is no way that HPA could somehow have been installed. Can someone confirm the correct number for me from the main screen of their web interface. Thanks.
March 13, 201313 yr 3,907,018,532 is correct. Mymain hasn't been updated with this value yet. You can go into disk properties and set: hpa_ok = 1 as a workaround until Mymain is updated.
March 13, 201313 yr Well, one line in the log shows: Hitachi_HDS724040ALE640_PK1331PAGR9UNS (sdl) 3907018584 But another line shows: (sdl) Hitachi_HDS724040ALE640_PK1331PAGR9UNS size: 3907018532
March 13, 201313 yr Author 3,907,018,532 is correct. Mymain hasn't been updated with this value yet. You can go into disk properties and set: hpa_ok = 1 as a workaround until Mymain is updated. Thanks for confirming this! I'm going to proceed with pre-clearing a second 4 TB drive so I can add it as a data drive. BTW I'm not sure what you mean by "disk properties". I clicked on the link in the shortened serial number in mymain but I don't see a "disk properties" setting. And in the "disk settings" on the Settings page in Main, I don't see it either. Not terribly important as it's only cosmetic, just would be nice to hide it. Thanks for easing my mind.

Not terribly important as it's only cosmetic, just would be nice to hide it. Thanks for easing my mind. Sure. Sorry I wasn't clear. If you go to the default menu in MyMain you can click on the serial ID for a disk, and that will bring up the disk configuration. You can then add an attribute for hpa_ok and set it to 1. That tells MyMain that you are confirming there is no HPA on the disk, even though it isn't a know size that MyMain recognizes. Here's a picture of what one of mine looks like:
