8TB Gold Unable to writ eot last bloc, of device

WD Internal Drives Desktop & Mobile Drives

Hi,
I’m trying to format my 8TB WD Gold. In disk utility on mac (10.10.5) it says it can’t write to last block of drive. Is there a firmware I need to install so my mac will understand a drive this large?
I ordered two drives and they both have the same issue attempting to format.
Thanks,
Mark

Hello there,

Try to format the drive in a different file system or perhaps a different partition table, maybe this will help.

Thanks ArMak. I tried all format options. I also tried partitioning from 1 to 4 partitions and none of those would let me format the drive. I’m still looking to see if there is a firmware update for my mac tower. I would assume if would be part of the OS install for 10.10.

You can also try to format the drives on a different computer and then put them on this one.

I’ve tried to format it on a linux hp, mac trashcan and mac tower. I found an old thread saying to use an old version of disk utility. That didn’t work either.
