Is anyone recording with the 4G split?
If so, are you having any issues other than the playback problem mentioned on SD support page?
Anyone running the repair utility proactively and what are your results?
All of last weeks tests (in the "slow media" thread) eventually showed problems when splitting at 4G even when using a freshly formatted HD. After seeing the note on the SD support page, I set to split at 2G and for the last 4 days, I've filled to about 75G twice and I'm into a third session with no problems at all. I think I was running 2G splits before Jim took it out. Of the files he captured, the 722 displayed the "slow" error only after he recorded a file that was 2600MB.
Also, even when the recorder was not showing issues, the file repair utility would detect errors in the filesystem when splitting at 4G. When splitting at 2G, the repair utility never detects an error.
So it's looking like this is not a heat issue or a HW problem with my box. Looks like a FW issue with large files.

The only problems Tim and I had were when I ran the 4 Gb split....ever since splitting at 2 Gb, the problems went away....fwiw, the problems were wavelab recognizing, opening properly...etc...

I was originally running 4G splits because CDwave handles the big files and putting back together pieces of a song that spanns the split seemed like a pain in the ass. I'll run 2G splits if that's what it takes to get the show home.
I just did another "repair" and there were no errors on the continuing 2G test. I'll switch over to 4G tomorrow and see if the problems return.
So when you split at the 2G but then need to downsample in a program that does not support 4G files, how you go about resampling across the file boundary?

My 2 Cents -
I ran a couple of time at 4G's and could not get things to work right.
Since I updated to 1.37 and cut back to 2G files I have had ZERO issues...
4G files time will come, just not quite yet.

We've been running the 4bg split since 1.32 (due to the filesplit bugs) and haven't had problems. CDWave handles the files fine. Joe may have switched it back while at the Roo but as far as I know, there were no issues while there.
I use Wavelab's batch process to do all my dither/resampling. Anyone have a problem with batch processing files? I haven't had any problems and love the convenience!

Question:
Does the 722 have pre-set file sizes ie. 4GB, 2GB or can you set a custom value ?
The reason I ask is when I used to use Soundforge to record the file size was always the biggest issue and has been dicussed here adnauseum. When I finally was able to make the switch to wavelab and set the autosplit I haven't run in to a lot of the weird issues that I would have in dealing with large files in SF etc. I set my auto-split at 1500MB (plently long enough for 1 set).
Putting files back together in wavelab makes it all very pain free. When a show is split and needs to be put back together I simply Add- Audio file to end and then choose a spot I would have normally made a track split and cut and paste a new file. It adds a step or 2 but is about as stree free as you can hope for

what issues were you seeing? The SDsupport page only mentioned playback on the 722 in the threads I read even though I'm seeing other issues.
i recombine the 2GB file chunks in the editor..usually using w64 file format....combining the split files is easy as cut/past....all resampling, etc happens to the entire combined file..then save out in wav chunks

If you don't mind humoring me in spite of my being too lazy to search, what is w64?
I use Wavelab's batch process to do all my dither/resampling. Anyone have a problem with batch processing files? I haven't had any problems and love the convenience!
I was under the impression that resampling operated on a window of samples. By your method, does the resampling slide that window across the split so that the edges are resampled properly?

apparently not. When I run shn tool over the 16 bit fileset, there are never any SBE's from the resampling process.

actually I cut the file up into tracks, join the split track, then do a batch resample in wavelab.....

My issues were more on the handling end than the recording end. Processing in Wavelab was not possible... Cutting into two pieces was a pain..lost info (probably my fault)
Once I went to 2G files I am running fine and have no reason to change for now.
I had a thermal issue but not since 1.37 was installed..
BTW - I have yet to be authorized to access the support forum.. after 3 direct emails...
Any suggestions <<<< not trying to hijack this thread, just frustrated>>>>

w64 is a file format in sonic foundry programs (Vegas, Sound Forge) that allows >2GB audio file sizes.
I record in Vegas 2.0, it records as .WAV up to 2 GB, when the file gets bigger than that it will change it to a .W64 automatically.

Sorry if this is off topic but
I have my 722 set at 2GB splitting... I open WaveLab, file > new > wav and then I, edit > insert audio files until I have the whole show in there. Then I add markers, auto split and lastly encode with FLAC front end.
Is this ok?
-
Sounds pretty much like I am handling things now..

Maybe try calling them? Of course it shouldn't be necessary, but you can talk with the same folks who run the forum on the phone, so I'd think you should be able to get hooked up that way.

Rick this is the same process I use also.

So, in wavelab you can assemble a sequence of files that exceeds 4G and apply changes/resample to that then save the individual tracks?
BTW, ran all night with no errors again at 2G splits. Running 4G tests now just to prove that is where the problem is, but it looks like 2G splits is the way to go for stability.

I do sets not the whole show at one time sorry I should have cariffied that. So im realy not forsure if I ever hit the 4gig mark.

whenever I have tried to join tracks and thus create a larger than 2 Gb file in wavelab, it tells me I cant do it....may just be a system issue on my end

It worked the last time I did it (the whole show was about 4.17GB)... I only did track splitting and fades though... Don't see why it wouldn't work for resampling too though...
What I do is:
File > New > Wav
Edit > Insert Audio files > At the End (just need to make sure you put them in the right order)
Add Fades
Add Markers
Auto Split
Its pretty easy... That's why I was concerned about it being ok. The key is you can't save anything until you get to the auto split part. Its the only work around I could find, and actually I think its the easiest way to do it too.

Have you tried it this way yet? I was getting the same errors, but for some reason this works :P
-
My experience with wavelab is that it will allow me to "join" the files regardless of size. The only time it has issues is if I try to apply gain or dither etc.
I usually just "join" the split tracks and pick a point in the show where I would normally have added a Track split. I cut the track there and paste it in to a new file. Thus creating a new file. I then apply the same amount of gain to each file and track etc

I was originally running 4G splits because CDwave handles the big files and putting back together pieces of a song that spanns the split seemed like a pain in the ass.
This is where timecode comes in handy. You simply dump the tracks and align things according to the timecode. It's too bad that you have to step up to the 744T for that option. I think it would have come in handy with things like the split.

I think the point would still remain that you are putting something back together in a program other than cd wave, which can be a pain in the ass. Still, I find that the 4 GB split means that I only have to merge files once where if I split it at 2GB, I'm merging several times per show.
