[Bug 1253443] Re: "failure writing to sector" error at boot with Advanced Format Disks

[Kent Baxley]

** Description changed:

  Testing the 14.04 daily server images, I noticed a minor error popping
  up at boot time.  See attached photo.
  
  I call this 'minor' because the system will still  boot by itself within
  10 seconds or so of the error popping up.
  
  This only seems to happen so far with Advanced Format disks when
  installed in EFI mode.  I tried two different hard drives and got the
  same result.
  
  Systems that are not equipped with Advanced Format disks but installed
  in EFI mode do not show this error.
  
  Steps to reproduce:
  
- 1) Install 14.04 amd64 daily server build. 
- 2) System needs to have an  Advanced Format disk installed and needs to be booted in EFI mode. 
+ 1) Install 14.04 amd64 daily server build.  Select the 'use entire disk' option to auto-partition the drive. 
+ 2) System needs to have an  Advanced Format disk installed in it and needs to be booted in EFI mode.
  
  Actual Results:
  Installation finshes fine but upon reboot the "failure writing to sector" error pops up after the grub menu.  System will boot on its own after about 10 seconds.
  
  Expected Results:
- Boot without the error message
- 
+ Boot without the error message.  
  
  The disk layout on this drive according to Parted:
  
  Model: SEAGATE ST91000640SS (scsi)
  Disk /dev/sda:  1000GB
  Partition Table: gpt
  
  Number   Start        End         Size         File system      Name   Flags
