No C2 support

[PedroT99]

So I just downloaded dBp and am getting started. I have not done the marker triangle test but I did let. EAC scan my drive. It says that my drive supports AccurateStream, does NOT cache audio but also says No to C2 error information.

Should I buy a new drive? Can't I still get error-free rips? I have no problem dropping 40 bucks on a new drive for a drive with C2 if it helps. That said, how do I know if a new drive would support C2 BEFORE I buy?

Re: No C2 support

If AccurateRip verifies a disc, it would not matter if you had C2 pointers or not.

Re: No C2 support

That is what I was hoping. Either way, I'd like to buy a second drive for tough discs as I think you recommend. I know you stay clear of recommending drives as they change often. To that end, the DAE features DB you have posted doesn't list a single drive that I can still find here. Is there anyway to figure out things like caching, C2, etc before I buy? Some sort of "advanced" documentation? I can't seem to find any specs besides the basics....speed, etc? I can't imagine everyone just buys drives and just hopes it has the features they want??

Does anyone else have a recommendation of a good internal (or preferably external) drives??

Thanks again!

The brand name on the box might not be the same as the identifier from the hardware itself. Confusing indeed. Matshita? That is Panasonic, and others. A search on UJ-85J, just to pick from the top of the accuracy list, indicates (but I'm not sure) that this is also used by Apple. Lots of them on eBay.

Externals, that's an issue: if you put a good drive in a USB enclosure, then there is no guarantee that this one will transmit to/from the drive anything except what is required to actually get it running. Even if the drive supports C2 error pointers, you cannot expect that to carry over.

Re: No C2 support

Thanks guys. Porcus, I've heard that externals can be an issue with respect to power and/or spinning at the right speed. That said, I thought putting a good internal drive in an enclosure would alleviate those problems. Am I misunderstanding that? I ask because I have no drives left and was probably going to get a laptop when this thing dies as its not worth upgrading.

Re: No C2 support

Anyone: would eSATA on a laptop usually hook up to the motherboard just like an internal SATA?

I don't think a good internal drive is enough. My impression is that you need to be lucky with both the enclosure's chipset, the USB-to-motherboard chipset and the firmware. I put up a question on top for whomever knows to answer -- it may or may not solve your problem.

Well ... how tech-savvy are you?

If the laptop has an internal drive, then it is replaceable. Google up the specifics for your particular choice of laptop.

Now if your laptop does not have an internal drive, then for an ugly-looking solution I would not keep permanent, but which may be useful for a few discs that need re-ripping: if it has a tray for a 2nd hard drive, then open the lid, get a SATA extension cable, and hook the drive up to that one. If you do not buy an &*8220;external drive&*8221; but rather an internal drive and an enclosure, then you can just bypass the enclosure's SATA cable and hook it right to the motherboard, yet using the enclosure's power supply (the drive may or may not need more power than an internal HDD).

The same could be the case for the eSATA thing I asked about at the beginning. I don't know.


If you have an internal laptop drive (say, intended to use as external by way of an enclosure), you can -- possibly by way of an adapter, if it is a slimline type produced for laptop use -- hook it up to your old computer too.

eSATA would not have pass through problems.

Re: No C2 support

Guys,
Thank for all your help! I'm almost done configuring/choosing formats, etc. and ready to start ripping.

One last question. I did the black marker test on one of my CDs. It made it about 10 to 12% through which took about a minute. Then dBp said that C2 pointers were detected, will be used and then automatically checked off the box to use C2.

My question is shouldn't it have made it about 25% through? I measured 1cm like the guide says to. Also....and not to commit a faux pas by bringing up other SW, but before I settled on dBp, I downloaded EAC and when it scanned my drive, EAC said that it did NOT support C2. If my drive does support C2, I'm pleasantly surprised....I'm just not sure what to think. Thoughts??

EDIT/Update....I clicked on CD ROM under dBp options and when I click on "technical" it says no to C2 error pointers. So on dBp, the marker test said it did detect a C2 error but the technical details of the drive (also in dBp) says it doesn't have C2 error pointers!

Not sure what to do!

Re: No C2 support

Try the marker test again, but do it right on the edge, you should see it only detect after > 50% of the disc read.

Re: No C2 support

There are a few of drives which falsely report not to support C2 pointers (for example, my Pioneer DVR-107D and 110D), when they actually can report C2 errors. Take into account the "Detect C2 support" test, it can detect if drive can report corrupt symbols when ripping.

According to latest post, I think you drive can report C2 errors. Try ripping a slightly damaged CD and check the ripping log: Search lines like this (C2 dropped n). If not sucess (any decent modern drive can read slightly damaged discs in a go, without rereadings), try ripping a heavily scratched CD and stop process when dBpoweramp reripped a few of frames. Then, check the log for C2 dropped n lines.

Isn't this precisely what is going on if you ask it to test for C2 support using a scratched CD?

Anyway, for the opposite scenario -- drive which reports to support C2 -- then you might encounter C2 errors everywhere. Perform the test, and it will immediately say C2 errors were found. Rip more or less any CD, and it will start re-ripping an enormous number of frames. In that case, turn it off.

Re: No C2 support

You are right, it is redundant. However, I am a little perfectionist and double-checked everything.

The opposite scenario is the case with Hitachi-LG SATA drives based on Renesas drives. They report falsely lots of frames as bad. I tested such drives in the past, and discovered that C2 pointers works perfectly ok only when using a app configured for reading sectors one-by-one, not in bursts of several sectors. Sometimes, the 8 KB option (I assume that it means bursts of 3 sectors, (2352+294)*3) of dBpoweramp can solve partially the problem.

I've seen it do precisely the opposite though. It doesn't hurt trying, as long as one doesn't panic over error messages.
