I bought the last burner I have, about 3 or 4 years ago at wallmart,
everything but Blue Ray, for about a $25 dollar bill. Internal, sata
interface. It has to date burned 2 or 3 100 count spindles of cd's and
dvd's, and has never hicupped unless the disk was phony. Some brands
have a high phony percentage. From an lshw report:
*-scsi:2
physical id: 11
logical name: scsi4
capabilities: emulated
*-cdrom
description: DVD-RAM writer
product: iHAS424 B
vendor: ATAPI
physical id: 0.0.0
bus info: scsi@4:0.0.0
logical name: /dev/cdrom
logical name: /dev/cdrw
logical name: /dev/dvd
logical name: /dev/dvdrw
logical name: /dev/sr0
version: GL1A
capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
configuration: ansiversion=5 status=nodisc
I've had a small wagon load of junk optical drives over the last 18
years, must have at least 10 laying around because I'm a packrat, but
this one has been a workhorse that doesn't seem to need any oats.
