hello

i own a mznh900 and i'm having problems recording on some himd disc. when i playback the recorded songs there are some gaps of silence in the middle of some songs. this is not happening with the old md 80,74,60 discs, only with 1 gb discs. i read a couple of weeks ago a pair of topics about this problem , but i want to know if anybody is having the same problem, or maybe my unit is defective?

tell me your experience. please help

well... in fact i beleive these are unit related problems.

I've had lots of problems with 1gb discs... somehow I managed to recalibrate my unit using the service mode. It was a heck to do it, i had previous experience with my mz r70 in this auto adjustment mode, so after a few days i was able to figure it out.

It's something that i don't recomend to anyone, since we still don't have service manuals available for the units... After clearing the NV i had my nh700 completely dead for a few days. I've managed to recover it back, restoring some service mode values that i've read in a list made by the user aiox and running successfuly all the auto adjustment modes.

After that i had no problems reading and writing 1gb discs. There was one particular disc that was almost full of errors, and with this adjustment i was able to fill it in, and copy the data back, and all the bits were in the right place (md5 hash checked!) smile.gif

So, just a thought... i think that some units aren't properly adjusted, not the discs that are defective.

Yeah one of the victims is me. It had happened after I recorded a concert, and the disc went mad trashed everything on my return home, and later it did all kinds of nasty things... not quitting the unit is one... gave all kinds of errors which I forgot what now. When it came out I saw that the metal part was slided down, I replaced it but didnt work... then it decided to work again and now it is still working. I dont rely on this one, but I cant prove that it is defective anymore. I think it is better to stay out of the 1 GB discs for a while.

How do you record? If it's software only, try recording via a microphone or optically via the optical in. Do a few tracks of that and see if it does the same just to rule out software.

i tried with the optical input also. same problem. when the unit is playing back the disc it start to make a noise a little louder compared to the normal one. it sounds like the unit is having problems to read some data. but this never happens with the normal disc and neither with "all" 1gb discs, just some. what should i do?

this happens to the same part of the disc . for example track 1 in second 10 has a gap of silence of 1 second.

this has just happened to me on a 60 min disc formatted in Net-MD. transferred via ss3 from mp3 to LP2 with the new RH910.

the mp3 is good but there is a 20 secondish silence in the song on the Net-MD disc.

hope this isn't a common thing or i'll be very disappointed.

--- UPDATE ----> i take BACK this post. the mp3 WAS messed up. i had both the 'clean' and 'dirty' version of the song. the one i listened to several times was the dirty version. the one that got transferred was the clean one.

i have done approximately 200 transfers so far to both HI-MD (mp3 to mp3) and Net-MD (mp3 to LP2) and have had zero "failures" with sonicstage 3.
