Very tight 11 Sector Tracks format (NOS) with very very short GAP between sectors (only 2 bytes!).At end of track: sequence of 7x$A1 Sync Mark (ISS), followed by $FF IDAM (IIF-NSI), Invalid Track Number (IIF-ITN), ID CRC Error (IIF-ICE), Sector with No Data (SND).S1: Sector Bit-rate Variation (SBV) but not Macrodos protection.ID is placed only a few bytes before the index. Sector with no Id (SNI) : Hidden data sector that contains 00 located between sector 8 and 10.The overall image quality is average but the conversion to stx seems to work. Image from Atari-Forum in SCP format only. Not sure if used for protection or notĭisk 2 seems to be single sided and not using any protection?īack to the top Air Sea Supremacy Compilation – Ubisoft 1989 track 82.0 and 82.1 are partially unformatted and partially contains data with sectors.We have some etra tracks (EXT) 80 and 81 on side 0 and one with 11 sectors.several sector with Data CRC Error (DCE)Īs we can see on this track some sectors are complete but reads with error, some sector are more or less truncated (SWS).several sector with Invalid Track Number 80 (IIF-ITN).T79.0 contains 59 sectors! In a very strange layout.Here we zoom where problem arises (at 161.5 ms). The only chance you have is to select a revolution where all the sectors are detected. In a case like this Aufit probably wont be able to create a correct Pasti stx file. Indeed if you look at the sector data display you will see that on certain revolutions the sector 8 (close to the end) is sometimes detected and sometimes not If you switch to the Data View tab and look at track content you will see that in some revolutions only 2 sync marks are detected in front of the ID field of this sector (and therefore sector is not found). This indicates inconsistent number of sectors detected by Aufit and thefore it automatically switches to safe mode. If you switch to the information tab you will see the following message "*** Sector not found exception T72.0 Sect count=10 *** switching to safe mode". You can see in the flux display window a red dot just before the detail check mark. Quality does not seems bad but in fact the track 72.0 has problems.
