I recently bought an internal DVD drive on eBay. I spoke to someone from LG but they say it's not an Australian model so they don't know anything about it. The drive didn't come with cables or a MANUAL, so I need help please.

About the DVD drive:
It is a 'Super Multi DVD WRITER GH24SD1'
It has two holes to put cables in. One is long and narrow and is labelled 'sata power CONNECTOR'. The other is short and narrow and is labelled 'sata signal connector'
Manufactured June 2016 (so it is not an old model)
ROM VER: LG00
S/N: 606HBXG102418
SVC Code: NSD1
Also it has HF20C above the holes for the cables

What I need to know:
1. What sata cables do I need to use this with my laptop?
2. Should the DVD drive still work in Australia, with Australian DVDs, EVEN though it is a different country's model? (I don't know which country, and nor does the LG rep)

I've found it listed in some people's PC builds which suggests it is internal as well.Yes, sorry, you're right about it being an internal DVD drive. I've corrected this in the edit. Those -SD1 model drives are seen in PCs sold in Germany, so maybe that country or mainland Europe generally. If it is region locked it is usually possible to change the region five times in Windows XP/Vista/7/8.1/10.
And any regular SATA cables can be used for the drive...The region setting would only affect trying to play region coded video DVDs (movies, TV show box sets etc).. It would not affect anything else like music CDs or CD-ROMs and DVD-ROMs, software install disks and so on.
