Actually, I found out what the problem might have been. Probably the recorder got jarred while taping or it was a bad disc (it was one of the newer blue transparent discs). And yes I have the latest version...4.3. So, what I did to counter it was I split up the recording into separate tracks for each song in the set and I was able to isolate the song that was giving me trouble - track 8 (I don't know what the song title was). I then transferred all the good tracks as normal via USB and I was able to play back the bad track and transfer it via analog through my mixer and out to my sound card. After that, I threaded all the tracks together in Wavelab using the "add file at end" feature. The only flaw in the recording was an 800ms silence gap about 90 seconds into track 8.
I have a really important concert coming up with my friends' band Knock Knock Ginger (www.myspace.com/knockknockginger) that I want to be sure there are absolutely no problems with. They are debuting some new songs that will be recorded over the summer on their first full-length album (they've already done 2 five-song EP's) and their former bass player's band from Montreal are also on the bill so it will be a very special evening. The show will be performed at the Grist Mill in Waterloo, Ontario - a replica of a mill structure from the mid 19th century. The location was originally Trepid House but due to an encounter with Waterloo's Finest, the location was changed (no confirmation but it makes sense). As far as taping goes, I plan to use a Sennheiser KE4-210-2 based binaural rig and a rented Edirol R-09 which will eliminate the need for a battery box and the need for me to carry a flashlight all the time as the MZ-NH700 I currently use has no backlight on it.
I know about Sony dropping the ATRAC format and SonicStage and I think the HiMD format had great potential and could have easily been a DAT replacement or a more cost-effective alternative to flash-based recorders. It sounds pretty decent too - low S/N ratio, transparent analog stage and ADC, all for around $200 at the time I bought it. Plus the discs are relatively cheap too compared to even the lowest priced 1GB SD card. CF is still really expensive too...I remember paying $175 in 2006 for a 2 gig CF card for a rented Edirol R-1 I was using to record a board mix of live music from a wedding I was running sound for. I even had to get a card-reader because I had to return the R-01 the next day.
So, the crisis is averted for now but while I haven't lost faith in the HiMD format, I'm starting to think my once-trusty MZ-NH700 isn't as reliable as it used to be. Maybe I should have it looked at or something because, like I mentioned earlier, I've been losing a lot of great musical moments because of it.
