i just purchased lite-on LTR-40125S over the web.
it came with the ZS0N firmware which is the latest.
i was so anxious to overclock it that i didn’t test
the drive at 40x. [:D]
i overclocked it to VS06 using mtkflash and tested with nero cdspeed.
nero successfully recognized the drive as LTR-48125W
and maximum speed was about 49. great. not!
everything looked o.k. on the screen but the disaster
laid upon me when i tried to burn a cd.
i tried to burn a single file, 700mb, and when the writting
process reache 54%, everything slowed down.
it took me 3:34 to write a disk at 48x. too long, huh?
and when i checked the cd quality using cdspeed about
7 million errors showed up and the green line had steep
dips going up and down. ummm.
i tried to solve the problem by
unchecked smart burn. didn’t work
tried different cdr mediums including fuji, tdk, verbatim, and
imation. all 48x compatible. all with tons of error and slowdown.
enabled and disabled dma. tried both settings. none worked
changed the firmware to VS02, VS04, VS08. nope.
reinstalled nero and installed the latest version. nah. didn’t work
changed the firmware back to ZS0N. no slowdown (burned 700mb in
3:06) but too much errors. about 3000 errors in cdspeed.[:(!]
tried windows version of flashers. same thing.[xx(]
yes. i’ve checked the jumper setting.
my computer has
pentium 4 2.0ghz northwood
asus ps533 with SiSÂ® 645DX chipset motherboard
samsung pc2100 512mb memory
western digital 40 hd (primary master)
western digital 120 hd (primary slave)
gefore2 mx200 64mb
generic cd-rom (secondary master)
lite-on LTR-40125S (secondary slave) (when using mktflash i used option 4, secondary slave option)
i misplaced my screw driver so i didn’t try putting lite-on drive on the secondary master, not that i think it’s gonna help.
so, any suggestion?
could it be that it’s a defect?
please help me out.
any suggestion will be greatly appreciated.
thank you very much for reading such a long post.
