Model numbering/internal hardware difference issues :

1.What does the drive model name/number mean?

Older LG DVD writers generally have a model name/number of the following form :

HL-DT-ST DVDRAM GxA-yyyyZ

From left to right :

• HL-DT-ST stands for Hitachi LG Data Storage
• DVDRAM indicates the drive supports read/write to DVD-RAM media
• 3 letters :
  • GSA drives are retail models
  • GWA, GMA and GCA models are OEM versions (see Q3, Q4 and Q11 for more information)
• 4 digit model number (e.g. 4160)
• one letter, usually :
  • B for internal desktop units (e.g. 4160B)
  • D for external units (e.g. 2166D)
  • N for ultra slim notebook units (4082N)

Newer LG DVD writers generally have a model name/number of the following form :

• The first three parts are still the same
  • HL-DT-ST, DVDRAM, GSA- for retail models
  • HL-DT-ST, DVDRRW, GSA- for OEM models
• one letter :
  • E for external units
  • H for internal desktop units
  • T for slim laptop units
• 2 digit model number :
  • even numbers are retail models (e.g. E10N, H20L)
  • odd numbers are OEM models (e.g. H11N) (see Q3, Q4 and Q11 for more information)
• one trailing letter :
  • A non-lightscribe models (10A)
  • N also non-lightscribe models (10N)
  • L for light scribe capable models (20L)
