Yes. Examples of this would be the following drives:
- LiteOn SHM-165P6S
- LiteOn SHM-165H6S (includes LightScribe)
- NEC ND-4550
- NEC ND-4551 (includes LabelFlash)
- NEC ND-4570
- NEC ND-4571 (includes LabelFlash)
- Pioneer DVR-111 (but be careful with the different versions of this drive, many versions don't support DVD-RAM writing)
LiteOn DVD drives can scan CD media for C1/C2, but they are completely untrustworthy for this purpose. LiteOn DVD drives can scan DVD media for PIE/PIF and they are the best drives for this purpose (along with Plextor drives).
NEC drives can scan CD media for C1/C1 and can scan DVD media for PIE/PIF. They are not considered very reliable scanners for PIE however, and sometimes they are even flaky for PIF scanning.
Pioneer drives in the past have been known to be very unreliably scanners. Whether the same applies to the DVR-111 remains to be seen.
Only you can decide that.
I think that's your best bet. The drives I mentioned are all internal drives.
I have tried the NEC ND-4551 in an external enclosure based on the Prolific PL-3507 chipset, and it can read at 16x using FireWire, but only about 15x with USB. Writing is also limited to approx. 14-15x using either USB or FireWire. The same is true for most other drives which use UDMA-2.
LiteOn drives use UDMA-4 and can run at full speed in an external enclosure (I have my LiteOn 1635S connected this way). I don't know how good their writing quality is with DVD-RAM media however. But if I had to make a single suggestion, it would be a LiteOn SHM-165P6S in an external enclosure with a Prolific PL-3507 chipset!
