Asus 22B2ST

#1

Does anyone has any idea if the Asus 22B2ST is a liteon drive?
I’m asking this beacause my sony dru860A@iHAP322 is almost dead (the cd part is no longer with us:iagree:)


#2

Asus has had many models following the LO trend.

This is my guess.
DRW-22B1ST = iHAS122 8
DRW-22B2ST = iHAS122 9
DRW-22D1S = ?


#3

Thank you KTL, i might get this, and flash it into a liteon, i only hope that this drive will be better than the ihaxx22 8 series.


#4

Well the drive has the MT1869L chip.

DRW-22B2ST == iHAS122 9 as they are using different chipsets.
DRW-22D1S = Using Panasonic chipset, may be a LG GH22NP20 clone?


#6

Verbatim -R 16x
MCC03RG20 @20x
All on


#7

Well, as far as I’ve collected, the MT1869L chipset has been used in iHAS120, DVR-218L, SH-S223F, and SH-S223B.

Can the 22B2ST perform a DQ scan in CD-DVD Speed?

Yes it scan dvs’s here is a scan.



#9

The Drive also supports jitter report with CD-DVD Speed V4.7.7.16 SE3.


#10

Trying to flash it with the 122 9 firmware didnt do anything the drive is identified as asus DRW-22B2ST plus it will do jitter as 2601 said.


#11

It does seem like the 22D1S is a LG 22NP20 clone. This is the closest to seeing a real picture and noting the closeness of the activity light and manual eject hole, as well as the 16x DVD+R9 write speed.


#12

ok here are some scans with the [B]DRW-22B2ST[/B] and the [B]DH20A3P[/B]

Is there a iHAS122 9 drive at all ? There are iHAP122 9 firmwares, but I have not seen a iHAS122 9 firmware.


#14

There probably isn’t an iHAS122 9, but iHAS122 A, since there are DL0A and DL0P firmwares available for the latter.

Thus, there are the original iHAS & iHAP 8 series, but the revised are iHAS A and iHAP 9.

I can sent you the firmware of my asus, assuming that this drive is an [B]iHAS122 9[/B].


#16

Your 22B2ST firmware is a DH22AZS firmware.

I dont remember any DH22AZS drives from liteon, thanks ala42.


#18

Could anyone share original unpatched DRW-22B2ST firwmare? I’ve restored our customer’s 22B2ST which was bricked by wrong firmware with C0deKing’s patched firmware but this drive reads discs very unstable on such high speeds (probably because of bad pickup). Thanks in advance!


#19

I no longer have the original firmware for that drive, maybe someone else has it and can upload it.


#20

I’ve found DH22AZS firmware and tested it on this drive - works perfectly. But still need original DRW-22B2ST firmware because the “ASUS DRW-22B2ST” name in Windows is required for this customer… :frowning:
