I thought I would add my experience to the thread. Prior to last night I had recorded maybe 8 shows with my DR-2D. I have the autosplit set to 512MB and am running mic-in with small omnis and a battery box. A couple of the recordings were at 24 bit / 48 kHz, but most were at 24/96. My memory card is an Adata, 8 GB, class 10. I had not had any problems with the autosplit or anything else. Last night that changed. The card was "Quick Formatted" immediately prior to the show because I did not want to individually delete the files that were on it.
1st band was recorded 24bit/96k mic in. No problems. (3 files due to autosplit, 1.3 GB total)
2nd band was recorded dual input, line (soundboard feed) + mic at 24bit/96k
Twice during the 2nd band, I received a 'Write Timeout" error. It appears that these errors occurred at 4.2, and 3.6 MB into fresh files after a split occurred. The error put the recording on pause (flashing LED) and I had to press stop and then record to get the recording to resume. Fortunately I was open taping and the obscenely bright record led clued me into the problem. I was literally 15-20 feet away from the recorder and noticed the flashing led when it went into the error.
Further investigation of one of the files finds that there is duplication of data. If the sections represented by samples 139,793 - 437,009 and 437,009 - 734,225 are compared, they appear identical. In fact, using Audacity I lined up those two segments and inverted the second. Playing them back together resulted in silence.
I will be submitting this information to the Tascam people and will post here if they have something useful to say. I will try to replicate this problem with the card in question and with a Sandisk Extreme III 4GB card to see if it could be possibly related to the card.
Anybody have any thoughts or suggestions about other possibilities?
