This is a quite old drive, it was released almost a year ago. We received it in the OEM package. The set of accessories is not scanty: user manual, interface cables and screws, CD with Roxio's software and a software DVD player. The design of the drive is typical of LG: it has buttons for CD playback control. Its dimensions are shorter by 1 cm than the standard ones.

Nero CD-Speed

  • Vendor : HL-DT-ST 
  • Product : RW/DVD GCC-4120B

  • Maximum read speed : 5632 KB/sec (32 X) 
  • CDDA accurate : yes 
  • Read R-W : yes 
  • R-W packed : yes 
  • C2 pointers : yes 
  • Speed settings : 27 X 
  • Read RAW mode : yes 
The drive provides just minimal possibilities to reduce speed in operation with CDs. 

Nero InfoTool

This is a standard support of reading of almost all existent formats of optical media. In other respects, everything corresponds to the specs. The programs do not agree in C2 errors detention support. 

Nero - Burning Rom

The drives supports such a useful function as buffer underrun protection. Besides, it's able to overburn discs. However, the write simulation mode is not supported. 

The drive is RPC-2 from the very beginning and it's impossible to turn it into RPC-1. But there is a utility which can set the zone counter to zero.
