Burn time getting slower [not Q, but solve the mystery]

vbimport

#1

i’m using 4163b with whatever firmware that last supported (the thing doesnt even show up in LG’s support page anymore)

when i first got my burner, i used ridata 8x dvd-r and i got consistent burns of 7-8 mins for ~4gb of data
then i switched to same but dvd+r and got around the same times

then i bought fujifilms 8x dvd+r for my crappier ‘i’ll burn these stuff for you’ disks, and they avg from 7-8-9-10-11-12 mins
i thought my dvd burner was crapping out because the burn times got slower and slower -> at the beginning, the fujifilm ones were still burning at 7-8 mins, with a few getting 12 mins, now it’s getting to about 9-10 mins

but after, i was still using ridata 8x dvd+r (diff spindal) and it started gradually getting 8-10 min || 9-12mins <-rarer burns

so i’m thinking the media was getting bad, i now, i bought TY 8x dvd-r thinking it will burn back the 7-8 mins i use to have, but no it’s getting ~10 min burns consistently

maybe my dvd burner was getting sluggish due to the ~280+ or so burns, but not the case, i pop the same TY dvds onto my laptop’s dvd burner and get the same time

what i’m thinking is since the burner uses different types of burning techniques (therefore different burn times), the media is just using different burn technique BUT that does NOT explain why my fujifilms dvd burned from 7-8mins to the current avg of 10 mins (same spindal)

anyone got a good theory as to why my burn times are like this?

Stay away from Ridata 8x DVD-R: major degradation issues!
Check the ones that you still have, and copy the rest of them.


#3

To see what happen during the burn, can you try to use CD-DVD Speed and do a “create disc” test?

The possible cause of this behaviour are a heavily fragmented hard disc (causing frequent buffer emptying) or problems with DMA.

Check the current mode enabled (the drive should run in UDMA-2 mode).

well, my ridata ones are fine, i keep my back ups in good condition, all look out for that, didnt know

ya, it’s in that mode
and about the fregmented HD, i dont think it is, yes my HD is heavily-heavily fragmented, but my laptop’s HD is not, and it’s getting the around same times for the TY dvd-rs, so i dont think that’s it


#5

ok, i just burnt a 4.10gb disc in 7:41
4 before it were ~10 mins each

wtf is going on


#6

Can you post a graph of the burning process with cd-dvd speed? In this way we can see what happen during the burn :slight_smile:

You can also do a simulation to not waste a disc

hmm, my old burn times, weird

seeing the sim, the buffer was always 97%+

maybe it is my frag hd causing flux in buffer (which i do notice sometimes in the burns if i’m paying attention), but this doesnt explain the burn times on my laptop getting ~10 mins on the same disc which the hd is not fragmented

here is some other useless info i pulled, maybe it will be of interest to someone else

If it’s the fragmented HDD the cause of the problem, you can see running again the test (again in simulation mode if you don’t want to waste a disc) selecting the “burn image” box too. Create an ISO file on your HDD and run again the test. In this way, the HDD will be tested too during the burn, and you can see if the buffer is a problem.
