[chris <1222313@xxxxxxxxxxxxxxxxxx>]

I've just got kernel 3.2.0-54-generic-pae. Still experiencing inconsistency.. 
- 1st testing : no delay
- 2nd testing : 30 seconds delay
- 3rd testing : 30 seconds delay
- 4th testing : 30 seconds delay
Those  testing running under different random conditions and I still haven't found the pattern.

PS: I said 30 seconds, but actually around 30-35 seconds

Title:
  0bc2:2300 [HP Pavillion dm3-1109TU] External HDD goes into low power
  mode delaying saving by 10-20 seconds

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I found that my 0bc2:2300 Seagate USB HDD with NTFS goes into low
  power mode delaying saving LO files by 10-20 seconds.

  250 GB Seagate Expansion Portable Drive
  ST902504EXM101-RK

  I don't know which part number is right, looks different what is written in the HDD sticker & box: (even same S/N)
  - P/N: 9SD2A2-500 (HDD sticker)
  - PN:9SC2M2-572 (box)

  sudo hdparm -C /dev/sdb1:
  /dev/sdb1:
   drive state is: unknown

  Neither of the following stopped the driver from entering a low power state:
  sudo hdparm -B 255 /dev/sdb1
  sudo hdparm -B 254 /dev/sdb1
