| Description | 18x DVD burner Supports DVD-RAM |
Before we complete this review, we will run some advanced tests on the LG GSA-H22N.
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 LG GSA-H22N supports all features CloneCD tests for.
The LG GSA-H22N is a "Two Sheep Burner" that can successfully write Safedisc up to V2.51.
16x and 18x DVD writing in an external enclosure:
We have placed the LG GSA-H22N in an external FireWire enclosure built around the Prolific PL3507 chipset for the following test burns.
A 16x DVD+R burn completed in 5 minutes and 42 seconds, the same time as it would have taken in an internal setup.
The drive's buffer level is stable all the way to the end of the burn, demonstrating the drive's ability to communicate at 22 MB/s necessary to achieve the full 16x speed.
An 18x burn shows signs of exceeding the maximum data transfer rate possible in our setup, but the LG GSA-H22N manages to complete the 18x burn without a significant slowdown, in 5 minutes and 17 seconds. This is about 15 seconds longer than it would have taken in an internal setup, but still quite impressive for a drive in an external enclosure.
The quality of the burned disc is nothing short of excellent, even in the final area where the drive was forced to repeatedly suspend and resume burning. We can observe some additional PI failures near the end, but their number is minimal, a testament to the drive's good implementation of buffer underrun protection.
DVD-RAM writing performance
i cannot burn a dvd multisession because i get "are you sure you want to burn multisession? any further session will not be recognized by your operating sistem" or something like this every time i want to start a multisession disc. if i select to continue i am able to write another session on the disc but this ruins it because it becomes somehow unreadable. can this be because the write mode is "disc at once" and not "track ar once"?
i tried to change it to track at once but the field for this option is not active so i can't
PLEASE help
Glad to see it isn't me! Excellent drive otherwise, reasonably quiet, extreemly fast and doesn't mind my dirt cheap no name disks.
earlier it used to write in 10 mins.
plz help me

It destroys DVD+RW media: I have new discs that are supposed to be good for 1000 re-writes but after 10 burns or less I started getting a message like, "this disc is nearing the end of its useful life." I have never seen this before in all my years of burning discs, and it does not happen when I burn these same discs in my BenQ. Also, I find that other drives have trouble reading DVD+R's that were burned with this LG. I replaced it with a Sony-NEC-Optiarc AD-7173A that seems to be much better. I will be very reluctant to ever get another LG. [And by the way, I did do the firmware update but it is very hard to find these updates on LG's website.]
