Slashdot Asks: SATA DVD Drives That Don't Suck for CD Ripping?

I recently retired my ancient AthlonMP rig for something a bit more modern, and in the upgrade got a new DVD±RW drive. Since I have the new rig and a lot more disk space, the time has come to re-rip my ~450 disc CD collection into FLAC (I trust active storage more than optical discs that may or may not last another twenty years). The optical drive I had in my old rig was one recommended by Hydrogen Audio or somewhere similar for ripping CDs, and can grab an hour long album in about five minutes. My new drive, unfortunately, takes about fifteen to do the same. With the number of discs I have to churn through and the near-instaneous encoding, it's somewhat annoying. After searching the Internet high and low for advice I came up empty handed, and so I ask Slashdot: are there any SATA DVD burners that don't suck at ripping CDs? Read on for more details if you wish.

To work around the problem, I've temporarily yanked an old Promise IDE card I had in an ancient K6-2 rig (timothy found parts of it in a dumpster even) and am using the old drive, but it's approaching a decade and was pretty heavily used. What with having lots of moving parts and a laser or three, I don't see it lasting another decade, and I'd like to have a drive usable with a bus that hasn't been deprecated for almost as long. I'd also like to avoid anything that can read/write Bluray, because the hardware implemented DRM is pretty heinous.

For those interested in the gory details of the hardware I ran cdparanoia -A on both drives: ide drive, sata drive. As you can see, the old drive is way faster, and it looks like the primary difference is that it also has a cache that works with non-linear access, but that behaves "correctly." If you own a drive you want to recommend and can analyze it with cdparanoia, I'm interested in seeing the output.

A note on software suggestions: it has to be FSF-definition Free Software, and GNU/Linux is the only operating system in my house. That basically leaves... cdparanoia. I'm a bit uptight when it comes to tagging (mostly because: once I've done this, will I ever have the stamina to re-tag? Nope), but I'm not trying to start a pirate CD factory and don't really care about getting 100% frame-accuarate rips, just error-free ones.

You want to use Secure Mode with NO C2, accurate stream, disable cache. Yes, we said DISABLE cache. Trust us on this. We checked. Very very extensively. Yes, we know it runs slowly: that is because it actually does need to physically read every sector at the very least twice - that's the POINT. Sadly EAC isn't open-source (and despite many years passing, there still is no open-source software that does a Secure Mode), and runs under Windows (although it will function in a virtual machine if the drive is passed through well, such as VMware).

    2. Use AccurateRip in that if you can. Matching the read offset is strongly-recommended-to-required - ideally, find one of the few drives that can overread into lead-in AND lead-out. You won't hear it on many discs, until you come across That One Disc that has the track transitions exactly just so and thoroughly audible if they're off (despite the Red Book standard having a truly ridiculous amount of defined leeway either way).

    3. Hardware time.
    a) Best case scenario: The Plextor Premium, which does have a (rare) SATA version as well as the IDE version. That is the best CD drive ever made, and it is the highest quality DAE drive ever made, by far. That, and the above software (especially if you set the drive to "first session mode", or use AnyDVD), will rip clean through any "Copy Controlled" discs you may have in your collection too, by virtue of sheer quality. Be warned: that drive is no longer made, and REALLY sought-after. It will cost hundreds of dollars to find one new, and any used ones will be totally clapped-out by a lifetime of ripping and burning discs in professional CD-R duplication towers, or poorly refurbished.
    b) Can't get that? The Plextor PX-716SA will do the best job of any DVD drive. If you can find one easily, grab it.
    c) OK, plan C: something else. You'll need to check up on DAE quality. Check the offset tables on AccurateRip, which might give you a few clues. Lite-ON are way, way more reasonably priced, and some models work well at this; check them. So do a few LG drives. If you get lucky, you may have some good hardware already. Be warned, however, that you may NEED AnyDVD to rip any "Copy Controlled" discs that you may have correctly if you don't use one of the few drives that are out there that can do the job.

    4. Destination: Rip it to FLAC --best.

I mentioned in another reply here that I've used cdparanoia pretty reliably, although there are still issues (you need to keep a close eye on the quality gauge, as its repair mechanisms can actually deterministically mess up a CD rip!) But with a high-quality CD drive (Like the Plextors you mention) that gives low error rates by default and some double-checking of cdparanoia errors (i.e. assume that if cdparanoia reports that a track has errors that it didn't correct them), cdparanoia will work about as well as any other option. Yeah, you can't recover from errors as well as EAC or dBPoweramp can, but if you've got a pretty clean CD collection, you won't be too bad off. Combine cdparanoia with some of the command-line AccurateRip tools out there (as you mention), and you can probably be pretty sure your rips are good.

      2. The only downside with AccurateRip is that it's not actually compatible with the GPL (use of the database imposes additional restrictions that aren't GPL compatible). The CUETools Database is GPL compatible (and even can repair some errors using some parity data!), but as of right now, no command-line tools play with it on Linux, and it's probably always going to be a little worse than AccurateRip due to fewer tools supporting it.

  8. Mass ripping by girlintraining · · Score: 5, Interesting

    The problem isn't the drive speed, but the amount of manual labor involved in placing hundreds of drives, sorting out the ones that have failed to be retried, and then restocking them. There are multiple optical disk loaders out there, but they aren't intended for transient use and usually require a painful data entry step at the beginning before the drive can locate them.

    I have a similar problem, but for a collection of over a thousand mixed-media items. What I've settled on is building a three-spindle set and using a robotic arm with a vaccum sucker to life each item off the spindle and set it into the drive. The spindles are incoming, complete, and failed. The arm is controlled by a simple microcontroller and a couple of sensors to track position and success of each pickup, and connected by USB to custom software. The software alarms if there's a failure, and stepper motors for precise location. The arm "free-falls" from the top of the platter (on a gas piston to reduce contact shock) and a pressure sensor to detect when contact with the next item has been made. It also controls the drive eject/load and the ripping software is triggered using auto-it scripts. Any failure is detected the same way, by watching window titles, and then signalling pickup of the optical media after. There is also a webcam placed directly over the optical drive insert with a bright LED, and a picture is taken of the 'top' of each inserted media at high quality (in case the title is only printed on the inner track). The picture is placed in the same directory as the ripped ISO, and each directory labelled sequentially.

    All of this makes post-processing a lot easier; The system can be loaded once a day (before I go to work), and when I get home, it will have ripped about 13 bluray discs. It only takes me a few minutes to rename each ISO to match the disk title from the image, after which it's placed in the pending folder which the ripper autoloads periodically.

    But this setup requires knowledge of basic programming and some basic understanding of how robotic tasks are performed; And a significant understanding of electronics and assembly. Any of the homebrew microprocessor kits out there can perform the interface tasks as long as they have GPIO pins. Arduino, for example, has pre-built shields for controlling stepper motors to further simplify this process. The hardest part for me was building the actual robot arm; For that, I looked to how 3D printers are assembled as they've largely solved the problem of using stepper motors and precise placement within a 3D space without significant feedback.

    Just make sure your robot's "sucker" can reliably release the optical media and not drag it; it only takes a little bit of moisture or stickiness to lift the optical media slightly and misposition it in the tray, and once the LOAD command is sent, your drive will eat the disc, permanently damaging it. It's also difficult to detect this in software -- the only indication of fault will be an unreadable disk and drive being unresponsive to load/eject commands. Make sure your apparatus fails safe, and I suggest testing all possible failure modes with throw-away media before using on production material.

    I came TERRIFYINGLY close to losing 20+ years' worth of files permanently last year when my SSD, my Velociraptor-300, AND my 2TB Seagate hard drive all kicked the bucket within a 3-month window of time. At the time, I had the SSD backing itself up to the Velociraptor daily, was backing up the Velociraptor (including the SSD backup) to the 2TB drive weekly, and had the Seagate drive itself backed up to a 3TB external drive once a month or so (the Seagate drive was normally stored at my best friend's house ~15 miles away).

    The problem was, as the drives failed and I replaced them, I ended up with multiple copies of recently-modified data, and ended up having a HELL of a time figuring out which was the new and which was the old copy. It took SO LONG to straighten out the resultant mess, that drive #3 ended up failing before I'd finished fully restoring everything from drive #2. And worse, because it took an eternity to do a full backup of the 2TB drive to the external drive (and 4-16 times eternity to restore it), I lost about a month's worth of stuff, and was in cold-sweat panic when I ran out to the store to buy yet another external drive to back up my last surviving copy of the data in case THAT drive failed, too.

    Yeah, 2011 was a really, really bad year for my data. In addition to the two external drives, I now also have a complete backup of their contents on ~50 BD-R discs sitting at my parents' house. It took me about a week to burn, and a loss bad enough for me to ever NEED those discs would be devastating... but at least I can sleep at night now knowing that I still have one backup of last resort to fall back on if necessary.

    After the crisis, I did a lot of soul-searching and research to find the most robust way to back up my data. What I learned (besides the fact that hard drive reliability has totally gone down the shithole over the past 5 years) was eye-opening.

    I'd argue that the SAFEST media for long-term archival backup of files is probably non-LTH BD-R media. It's phase-change magneto-optical, unlike the organic dyes that were the norm for CD-R/RW and DVD+|-/R/RW.

    For the record, "LTH" BD-R media uses organic dyes, just like older media, and anecdotal evidence suggests that data written to them has a half-life of approximately 6 months before they start getting correctable errors, and an estimated 18-30 months before they start getting their first uncorrectable errors.

    In contrast, most of the phase-change magneto-optical media made by Matsushita and Sony ~15-20 years ago is still readable today (assuming you can find a working drive), and there's no real reason to think BD-R will be any worse (fundamentally, it's the same process now as it was back then... just smaller particles and tighter laser & magnetic fields). In case you're wondering what's magic about them, it's because MO drives use the laser to briefly liquefy the substrate so metallic particles within it can move, and use magnetism to align those particles while it's liquid. Once they re-solidify a moment later, your data is basically "cast in stone" and has no real expiration date.

Plextors are, overall, among the more troublesome drives _unless_ you're using a ripper that does no retry checking (ie, NOT cdparanoia and NOT EAC). If you use iTunes, you want a Plextor. Otherwise, avoid them.
