LG GGW-H20L mini review by hwp

#1

This thread is to collect my findings about LGs GGW-H20N (HL-DT-ST BD-RE GGW-H20L) with Firmware YL02.

The drive is of the SATA variant and connected via PATA-SATA bridge (Marvell) to an Intel ICH4 UDMA 100 PATA port.


#2

[B]Firmware Update[/B]

A firmware update to YL02 with the drive connected externally via USB to SATA bridge (Scythe Kama Connect SCUPS-1000, JMicron) was not possible. The Update would start but hang. The update succeeded with the Marvell bridge.

[B]Reading a badly pressed Data-CD-ROM[/B]

This is the Driver/Software-CD that came with my LiteOn LH18a1p drive.

TRT-Test:

[B]Taiyo Yuden, Type 1, 700MB, 52x[/B], as sold by Verbatim

40x P-CAV writing speed selected, no slowdowns.
1538 C1 errors. A very good result for a full speed burn.

C1/C2/CU and Beta/Jitter scans done with the Plextor Premium:


#5

[B]Mitsubishi Chemicals Corporation, Type 3, 700MB, 52x[/B], as sold by Verbatim

40x P-CAV writing speed selected, no slowdowns.
18283 C1 errors. A very good result for a full speed burn.

C1/C2/CU and Beta/Jitter scans done with the Plextor Premium:


#6

[B]Ritek, Type 7, 700MB, 52x[/B], as sold by Maxell

40x P-CAV writing speed selected, no slowdowns.
11210 C1 errors, 63 C2 errors.

The result can be judged ok, since these media seem to come in a mixed quality. For comparison here the Plextor Premium2 has no problems with them (without PowerRec!):

[B]Taiyo Yuden +R 16x (Yuden000 T03 00)[/B], as sold by Verbatim

Burn speed 16x P-CAV, no slowdowns.
While the error levels seem to be consistent with what i get from other drives with this batch of media, there seems to be so be a problem that let the B/J-Test fail.

#8

[B]Taiyo Yuden -R 16x (TYG03)[/B], as sold by Panasonic

Burn speed 16x P-CAV, no slowdowns.
The error levels are somewhat higher to what i get from other drives with this batch of media. Again there seems to be a problem that let the B/J-Test fail. This time this coincides with a PIF spike.

[B]Verbatim +R 16x (MCC 004 00)[/B], CMC made, as sold by Verbatim

Burn speed 16x P-CAV, no slowdowns.
A very good result.

#10

[B]Verbatim -R 16x (MCC 03RG20)[/B], Prodisc made, as sold by Verbatim

Burn speed 16x P-CAV, no slowdowns.
The error levels (especially PIE) are somewhat higher to what i get from other drives with this batch of media. See for example Samsung SH S202N:

[B]Sony +R 16x (Sony D21)[/B], as sold by Sony

Burn speed 16x P-CAV, no slowdowns.
A very good result.

#12

[B]Sony -R 16x (Sony 16D1)[/B], as sold by Sony

Burn speed 16x P-CAV, no slowdowns.
Aside from a lone PIF spike of little consequence, a very good result.

#13

[B]CMC Magnetics -R 16x (CMC MAG AM3)[/B], as sold by Philips (labeled made in Taiwan)

Burn speed 16x P-CAV, no slowdowns.
Quite a bit of PIF. Again B/J scanning fails at the first occurrence of a PIF spike.

[B]Infomedia +R 16x (INFOME R30 00)[/B], as sold by Philips (labeled made in Taiwan)

Burn speed 16x P-CAV, no slowdowns.
A (very) good result.

#15

[B]TDK +R 16x (CMC MAG M01 0)[/B], as sold by TDK

Burn speed 16x P-CAV, no slowdowns.
A bad result. Especially since the drive continued to write a full speed and did apparently not notice the rising problems.

[B]TDK -R 16x (TTH02)[/B], as sold by TDK

Burn speed 16x P-CAV, no slowdowns.
A (very) good result. The PIF-cluster might be an individual media problem.

[B]Moser Baer India +R 16x (MBIPG101 R05 01)[/B], as sold by Imation (labeled made in India)

Burn speed 16x P-CAV, no slowdowns.
Aside from a lone PIF spike of little consequence, a good result. The two PIF-clusters might be an individual media problem.

[B]Moser Baer India -R 16x (MBI 03RG40)[/B], as sold by Imation (labeled made in India)

Burn speed 16x P-CAV, no slowdowns.
Aside from a PIF spike a good result. Jitter goes up.

[B]Preliminary DVD-DL results[/B]

A word of warning to all who want to use this drive to burn DVD-DL media:

So far i’ve wasted two perfectly good Verbatim +RDL 8x media while trying to run tests. In both cases the writing process ‘hung’ after writing some MB into the disc. Since my current setup works just fine with DL on any other drive I have I supect the drive to be at fault. I’ll report back once if find more time for further testing.


#20

Nice review.

How do you find it at reading DVDs?

I tend to find it seems to give up reading and the error correction is not that great compared (using CDSpeed) to some of my other drives.
