I have two IDE drives in a mostly SATA system. After upgrading from 4.5.4 to 4.7, these two disks are reported as DISK_WRONG. The main web page reports that the drives are 4 bytes smaller than the recorded (or expected) size. See the attached screenshot for the Main menu report which shows the correct disk serial numbers but different sizes.

Search for HPA in the forum.

Thanks. Booting up under 4.7 confirms that HPA is the trouble. But there's nothing to be done to fix it, at least under this OS, because hdparm says:

 

# hdparm -N /dev/hda
/dev/hda:
The running kernel lacks CONFIG_IDE_TASK_IOCTL support for this device.
READ_NATIVE_MAX_ADDRESS_EXT failed: Invalid argument

 

I guess I'll just stick to 4.5.4 until I need to replace these drives.

Can anybody say if the 5.0-rc4 kernel has what it takes for hdparm to remove the HPA from my IDE drives?

Is that drive really an IDE drive?  If not, is you enable the native SATA commands in the BIOS (enable AHCI for the disk controller) you might have the needed IOCTL.  Otherwise, you'll need to boot up seatools, or some other dos based utility to get rid of the HPA.

Thanks, Joe. I'll see if I can set in for AHCI in the bios. Yes, I really have two old IDE drives in the system, 500GB and 750GB. I feel like a dunce for not finding the posts here about banishing the HPA with SeaTools and HDDGuru when this came up in the winter, so I'll put the drives in a windows machine and try them if AHCI doesn't improve the situation.

Only do ONE at a time, otherwise unRAID will think there are TWO new disks in the array and you'll not be able to start it.

 

Remove the HPA on one disk, let unRAID rebuild it onto itself, then repeat the process with the other.
