[QUOTE=Albert;2750685]Ideal available drive for scanning DVD media: any new LiteOn 24x DVDRW drive. (No problem there).
Worth mentioning that the Lite-On ‘W’ drive is NEC-based, so scans like an Optiarc (which is essentially what it is - an unreleased Optiarc design). So no jitter reporting, but better for scanning CDs (C1=E11+E21+E31) and a choice of 1ECC or 8ECC DVD scanning.
The ‘E’ & ‘F’ drives are still Mediatek-based, so scan as one expects from a Lite-On. Although as with all ‘A3’-type Lite-Ons, CD-DVD Speed will not report jitter unless you use the SE3 version.
Your Samsung is Mediatek-based so, apart from not reporting jitter, it should produce similar results to a Lite-On DVD writer.
Ideal available drive for scanning BD: none (Samsung slim BDRE drives can scan but doesn’t report jitter; would have to find a LiteOn iHBS112/212/312/clone to get jitter on BD & DVD scans)
I don’t trust the Lite-On BD writers for scanning DVDs. Both of mine seem to be dropping a lot of samples. They consistently report about half the number of PIE as my Mediatek-based DVD writers and the average scanning interval is about 2 ECC.
There are some Lite-On iHBS drives (and & Teac clones) still available new in the UK. A couple of specialist online shops have them, but mainly Amazon Marketplace (and occasionally Ebay).
Ideal drive available for scanning CD: none. (Nothing made recently supports jitter scanning for CD. The no-longer-produced Optiarc DVDRW drives could give decent results, but didn’t support jitter on anything. The old genuine BenQ and Plextor drives really offered the best set of options in that regard. MediaTek drives still aren’t reliable CD scanners).[/QUOTE]
If you are serious about CD scanning, get a Nexperia-based Benq clone from Ebay, preferably a DW1640 (DW1650 just as good but no firmware which doesn’t pause during scanning, not too sure about the DW1620). There are [I]always[/I] some used ones around, mostly Philips clones starting from under Â£5 inc. P&P (and even at that price most don’t sell). These report jitter and, using the advanced scan in CD-DVD Speed/DiscSpeed, all types of error separately (E11, E21, E31, E12, E22 & E32).
Of the modern drives, Optiarc drives (from the AD-7200 onwards, not AD-7220 = rebadged Mediatek Lite-On) are the best option. In terms of what types of error they can report, they are comparable to the old Lite-On CD writers (C1=E11+E21+E31, C2=E32). Unlike the old NEC drives (and many of the Lite-On CD-RWs) they seem to be consistent scanners.
Mediatek-based DVD & BD writers (Lite-On, Samsung) report fewer error types when scanning CDs - only level 1 & 2 failures (C1=E31, C2=E32). But they are useful if you understand what they are reporting. It is very useful to be able to see level 1 failures (E31) reported separately - continuous errors are a sign of a very bad disc or writer.
In summary, the best [I]current[/I] drive for scanning CDs & DVDs would be [I]two[/I] Lite-On drives - a Mediatek-based one (E or F) and a ‘W’ drive (which I count as an Optiarc in all but name). The former for scanning DVDs (with the latter useful for a second opinion, when set to 1ECC mode) and both in combination for scanning CDs.
