3 Disks failed, 2 back, still trying case # 20574298

Yesterday (July 17th) Tech Support is rescalating the case, I just double check that ReadyNAS is reachable from their facilities through a PUTTY check, but, I got curious and issued a sfdisk -l command, and got:

# sfdisk -l

Disk /dev/hdi: 243200 cylinders, 255 heads, 63 sectors/track
sfdisk: ERROR: sector 0 does not have an msdos signature
/dev/hdi: unrecognized partition table type
No partitions found


As far as I understand, the HDD#4 /dev/hdi reports error as it is just a brand new HDD, and I have not partitioned nor change nothing, I wonder if some Jedi could make a guess about the situation and how bad it looks...

A sfdisk size command shows:

# sfdisk -s
/dev/hdc: 1953504344
/dev/hde: 1953504344
/dev/hdg: 976554308
/dev/hdi: 1953504344
total: 6837067340 blocks
#


And that is correct, as HDDs 1,2 and 4 are 2TB units while #3 is the original X-RAID survaivor of 1 TB.

I'm just waiting for a L3 engineer to connect to the ReadyNAS, something I just not be witness since April...and feel a little bit armless...so close as I recovered 2 of 3 damaged HDD, but no Volume C recovered yet...
