kind of major breakthrough... one of LGs verified successfully for the first time, it was malfunctioning because of a dirty/dying lens, anyway read speed is still 2x. i burned disc after disc all day long, and then suddenly it stopped burning, same way it stopped verifying before, just froze at 10%. one disc failed, and the next one started burning with 1,9 speed (set 4), instead of 4x with 4 real speed, as successfully before. I have opened drive, it was cleaned before for sure, because it was clear inside (impossible to see no dust in 2009 drive). Someone must have clean it and probably used compressed air, which sometimes (some cans) contains oil/gas ( i was shocked when i saw it once written on container, unfortunately after cleaning my drive with it and when it stopped working because lenses was covered with oil, fixed that easily using method below). Because i have no cotton swab and isopropyl alcohol at this moment (but will order to have a spare just in case) i made few "rounds" of 3 different brands cleaning discs, and then next disc burned over an hour with speed ... 1.2x - but verify was done !!! (with speed ~1.8x) but with success, completed 100%. Then the next failed, so I have no longer hesitation to claim its a faulty drive. Switched to another one - it burns fine - but unable to verify, so it will probably die very soon too. Besides that they are reading slow, but well. Anyway wasted saturday and few discs for 15$ per piece. Was it worth it? Well, I dont think so. Switched to my liteon, and will talk to the seller with unknown doubtful result. I'll try to clean lenses properly when i get my order, but if its dying laser, and it seems it is, then its just piece of trash. I've found out some clues at google regarding dying drive /laser/lens stages, first it fails to verify, then to burn and then will not even recognize disk... to be honest I had dozens of optical drives, and never had such issue (the only one died was SONY DRU800A i remember to this day) I have not tried safe mode, and as far as i know i dont have ahci. Assuming this situation, it was very misleading for longer time period until it became obvious. Liteon scans bdrs burned at this one, still living LG are perfect, even before that second died every burn was perfect. Two words @ liteon, had dozens of them, even before bdrs. My favorite one back in the days. I can say the opposite to my liteon history, and even this one i'm using on a daily basis ihbs112 , since 2012 , near 3k burned discs and works like a champ (each one with verify and additionaly quality test so at least near 10k write/reads) I have no idea what purpose of those drives could be for me. I wont use it if I cant verify against image. Probably most of ppl wont use it as a reader because 2x speed is not enough to play smoothly. Another lesson learned the hard way, damn.

SPTD removed - unfortunately nothings changed, started verify, read speed started ~0.5x and drops to 0.0. at 14 seconds. @ CDROM its just bad naming i think, drivers are dated 2001-07-01, version 5.1.2535.0, type CDROM/DVD - same with other drives, so its not an issue either. anyway i can change / update drivers if there are any newer, but i dont think this is it. LG burns and reads what LG burned, using explorer copying, opening etc, unable to verify and slow speed are the only issues. Also both ways, liteon reads what lg burned etc, it really does a great quality burning job. Burning BDRs. DVDs are dead to me for good since 2012 when i have burned last one. It never fails i guess, log is clear and fine, nothing is reported there when drive getting frozen. It frozen since 10minutes at 0% 0,00 x speed , last log is verifying track 1 of 1 ... I can paste all of it, its only drive/imgburn frozen not the computer/OS one more important thing - if i'm using any other app for read tests which is not blocking tray while read operation, i can "unfroze" drive when it stuck by opening tray, sometimes. Its not going to happen with imgburn , cause it blocks tray, only reboot helps, I'll try to untick blocking tray in imgburn and recheck. LOG I 20:49:43 ImgBurn Version 2.5.8.0 started!

I always use imgburn 2.5.8.0. with write/files folder to disc chosen from menu. (right side , up at ez mode picker) I'm not using any secured data/discs, just burning unprotected "clean" mkvs, no conspiracy theories needed Yes, I'd say that one more time, I've never seen such thing before thats why i wrote. I can complete read and copy to the drive, but cannot verify, funny. disc contains mkvs, different mkvs, I can burn it with pure empty 0 and 1 - and i bet we will have the same situation, copying succesfully done to the drive, verify frozen and dead within 20 seconds. I dont remember about SPTD, probably Daemon Tools back in the days, but liteon works good, could it be so dramatically different for two different drives? I doubt it but we may try to get rid of it if necessary to be 100% sure. I switch drive to liteon ant its ok, then switch to lg and we have a problem, even same cable, same sata port etc... everything is the same way. LG drives are 2009, liteon is newer 2012 and works fine. Its probably not a driver issue, because i can write without any problems, read too, just verify and speed are issues here. XP naming/translating is old, I will recheck but liteon was recognized witch same 2001 CDROM driver/name, but i will recheck this when switched. Yep, manual verify is not going to happen on LG, same thing with any read test with random apps, opti drive, nero disc speed etc. It reads up to 20 seconds and is "frozen."

Just tried to start verify only surface of the disc (from main menu). It starts to read ~2.5x then drops to 0.00 and goes to sleep/dead after ~ 20 seconds of reading, led is not blinking, nothings happening........so weird. Cancel wont help, because bus does not respond i think, the only way is to reboot, power offline. Meanwhile I can normally work on computer, clock is ticking, and imgburn is working, just with no read speed. After reboot, I can read files and copy them to drive with no problems, just slow. What is going on here ... weird

The thing is I'd like to verify with the same drive, or if its not possible and we will not resolve issue with LG drive, then to choose another. I'm burning single files from HDD, not image, so I cant verify them other way sector by sector, cause when its not image it only scans surface of the disc right? (it does not compare/verify sectors from disc with sectors on hdd/file ? ) So the only way is to verify with "tick" when burning, also using same drive, cause there is no other choice when prompt to verify/eject tray/choose other drive to veirfy? Never had to do this the other, the hard way, been used to verify tick and done, is there any other way to verify the same way as with tick or also choosing other drive to do this? I guess verify from main menu, without image selected, scans only surface of the disc, and "verify after burn tick" compares it at the same time with hdd / files burned of hdd, so its completely different verification right? Surface of the disc, and burn may be good, but if we have bad ram for example, cable or so, there can be lot of miscompares, which verify of disc only will not reveal. I've found it probably has something to do with firmware-hardware restrictions @ LG, kind of riplock. Yes, i can copy with LG what LG burned, its just veeery slow, because of some restriction, and its not bad quality of media, cause it looks good and fast at other drive, takes ~16mins to copy x8 23GB (liteon ihbs 112), unfortunately LG needs ~50mins ~2x to do the same. I bet its not the age, just LG. I have older and much more used drives and they are doing just fine, besides its about 2 pieces, not one, which could be failing. Probability of 2 pieces failing same way, same time is very doubtful. Besides they write and read perfectly, really ! Just so slow read speed and unable to verify needs to be resolved somehow. thanks for replies

Hello everyone, my first post here I've been burning CDs,DVDs,BDRs since it appeared, usually with slysoft clone, nero, and since few years imgburn, great app and free ! I have no problems related to my drive which I use on a daily basis liteon ihbs 112, but recently i bought for 30$ two pieces (15$ each, so very good deal i think) of used Hitachi-LG Data Storage drives, BH20N models, both made in JAPAN (with fujitsu-siemens stickers) LGE - DMBH20L( to be exact. 5V/12V = 1.2A / 1.6A manufactured june 2009, rom ver 1.01 I've spent few hours to read about my issue which is probably not a defect (because both drives have it), but some riplock or so. Not sure i'm posting it in good place cause it may be and probably is hardware/firmware related mainly. I have no such nor any problems with imgburn using liteon. It is impossible to verify burned successfully disc, even if it starts (it may reach up to 10%) the drive "dies/freezes", led is no longer blinking, speed is 0.00, it does not respond and even computer cannot shutdown or reboot, i have to use power off or wait 15-30mins or sometimes even waiting/cancel does not help. Same thing applies to transfer rate test in opti drive control, it runs for a few seconds and stops. Same with copying files burned correctly before (also tested on another drive(s) - it will copy 1 or 2, 7-8GB files and "die" at the end of disc during copying 3rd file same size. When I copy files separately its fine. Quality of read and write is perfect. Its only about the issue of freezing drive, unable to verify. I've already tried to update firmware with success, but this issue is not resolved. I had FW 1.03 and then 1.15, then tried to speedpatch. in failsafe mode its model HL-DT-STBD-RE BH08NS20 COR4 and i will try to crossflash it soon, but anyway it should be able to verify now right? I'm aware of no quality tests available because of LG chipset , but hey we're talking about verify. Read speed of drive is very slow ~2x, besides it has 6x specs and even 8x possible @ hardware when crossflashed. It takes ~40mins to copy whole disc 23GB. It burns well, quality tests of discs burned with these LG's are very fine. It would be good to have possibility in imgburn to choose/change which drive should be used for verify. How can I burn with drive(s) I cannot verify... makes me sad, please help. I'm using on daily basis imgburn with verify and even opti drive quality test with liteon ihbs112 pl06 drive, so never had such weird LG-infamous-issues. Oh and i use it at win XP, so win7 hibernation/driver related issues, fixed with later firmwares does not apply to this case. After many hours of testing and reading I gave up now, maybe some of you have any ideas that can help with firmware/crossflash, low read speed and mostly - freeze - verify things. I can attach any files, screenshots, logs etc when needed, everything is correct i think, no problems with other drive, and it just stops (not to be mistaken with slows @ bad quality) reading right after verify starts. edit: FW. 1.15 with speedpatch applied - it takes 45mins to copy 22.8GB thanks in advance
