Advanced Test
To round off this review, we will run some advanced tests on the Sony DRU-830A.
The “Sheep Test”:
For this test, we will use the Sheep tests made by Alexander Noé. Why is it called sheep test? That’s because the logo of the first 1 to 1 copy program called CloneCD is a sheep. When looking at supported writers, you will notice that the feature list has sheep to indicate if a feature is supported or not. In this case we are interested in the writer’s ability to backup/write weak sectors. Also called: “Correct EFM encoding of regular bit-patterns.”
- No sheep: Can’t backup any Safedisc 2 versions without the help of software tricks
- 1 Sheep: Can backup Safedisc 2 up to version 2.4x without software tricks
- 2 Sheep: Can backup Safedisc 2, including version 2.5x
- 3 Sheep: Can write all possible weak sectors, few if any writers could do this.
One of our forum moderators Womble, has written a guide concerning the “Sheep Test” that can be found here.
In the screenshot below taken from CloneCD, we see the Sony DRU-830A supports everything.

The Sony DRU-830A supports RAW-DAO recording mode, which basically means, it can write uncorrected data and sub-channel data.





As we can see from the table the Sony DRU-830A is a “Two Sheep Burner”, it successfully write the Safedisc V2.90 but however failed to write the Sheep3 tests.
CD-R Overburning test:
To test the CD-R overburning capabilities of Sony DRU-830A, we used the overburning test in Nero CD-DVD Speed. According to Nero CD-DVD Speed the drive can overburn disc larger then 99/100 minutes. For this test we used unbranded Infodisc 99min/900mb CD-R which is rated 10x speed.


The Sony DRU-830A reported no problem with an overburn capacity of 99:00 minutes in simulation mode, so we attempted to created a test disc using Nero CD-DVD Speed. See below:

There are no problem writing this media around 99 minutes. We now ran a quality scan to check the created discs readability.

The scan shows a very good result. We conclude that the Sony DRU-830A supports overburning 99 minutes CD-R.
DVD+R Overburning test:
To test the DVD+R overburning capabilities of the Sony DRU-830A, we used the overburning test in Nero CD-DVD Speed with Taiyo Yuden DVD+R 8x certified media.


From Nero CD-DVD Speed Overburning Test screenshots above, the drive does not support overburning. The test stopped at 4482MB which is the standard size for DVD+R media. We will now attempt to verify this using Nero CD-DVD Speed Create Data Disc:

As you can see that the drive failed to overburn the media. We conclude that the Sony DRU-830A does not support overburning 4600MB DVD+R.
This concludes our Sony DRU-830A review, lets head on to the last page to read our conclusion…

my dvd riter sOny DRU-170C giving me same things. it isnt reading any of DVD s and saying that insereted disc is a blank cd (instead of a DVD ).all of my frnds having same problem . it s IC problem . The IC of sony dvd riter /cd riter is faulty ! and they arent taking pains to rectify the errOr! sony sucks!!!!
P.S http://sony.storagesupport.com/dvdrw/firmware.htm
I personally feel with most stores carring blank DVD's there is a large market for making back-up copies of your DVDs and Sony has missed the boot on this issue! The Lie-On DVD Burners is a better choice for those of use who have a need to make back-up copies of their DVDs and no drive that does not support BOOK TYPING should not be considdered! :g

Dru 830 a is pure madness... Are you complaining about "complex" things like recording? Well let me tell you about the most shitty issue on this player/recorder... My dru 830 wouldn't play movie dvd's correctly... And I bought this unit to enjoy the capabilities of my computer to watch movies... At this moment I have no money to afford a new dvd-rw... I've tried everything... from the new firmware to the IDE device set up thingy. none of them worked... The error message when playback? "Css copy protection failed" I'm really pissed off...
