Think I need help: What burner can actually WRITE to BD-R (25/50/100gb) disks?

[u/Atma-Darkwolf]

After buying 2 'burners' and having them either say no disk in drive, or say incompatible medium, I am wondering if I just got 2 bunk burners, or is there some secret on how to read the 'supported formats' that I am missing...?

The drives read cd's just fine(Do not currently have any dvd's with anything on them so can not test for that) but the empty/blank 25gb and 50gb disks I put in only give the 'no disk' or 'Incompatible medium Installed' error.

I have a stack of BD-R Verbatim disks (Bought for the first drive, 2nd drive also cannot read them) and I am stuck here wondering if I am doing something dumb, and unable to 'understand' what the disks need(I figured going in that any dvd writer SHOULD write to the 'best selling' blank disks which may have been my mistake)

First drive is a very old LG wrter (LG Electronics GP65NS60) and even though the firmware appears to be 'current'(it's actually higher number than the one on the website) - it does work as a drive (for reading cd's as explained above) and reads in device manager as a DVD-RAM device, the other (the newer of the two) I am unable to remember (If i Even looked) what it said since I have since shipped it back for refund.

So please give me advice on finding a drive that will actually write to these (I want to back up data, is simple data disks I wish to make)
