Want to have external DVD Writer so what will be the total cost of LGH42N and good external 5.25" casing? moreover my comp has USB 1.0 port so will newer external casing support USB 1.0?
Yes, USB 2.0 is backward compatible with USB 1.0, but why do want to connect it externally ? It might result in several coasters with the external drive.
Yep. Burning at USB 1.0 speeds will mean a lot of interruptions because of the poor data transfer rate and the disc burn quality will be very poor, if it finishes burning at all.
got a laptop with combo drive so thats why wanted external drive. But if it will lead to various problems as u both say then will connect it internally.thanks to both of u for ur guidance.
