used DOS assembler written tool (downloaded from optical media recovery toll site) that accessed DWD directly without detection sequence required
usually hardware DWD reader first have to detect, it was like infinite loop moving dwd heads sound tryin to detect it for about few minutes than silence
assembler written tool skipped detection stage somehow and copied data sector by sector to dump file on PC drive
it is not ISO, it RAW copy of DWD sectors stored in one file, to confirm it is not garbage archiver was able to extract "Microsoft Basic Data" partition from it
password protected archive usually produce data looking like garbage actually it is not
zip signatures is exactly Im looking for, possible select zip signature with further data in hex editor and save as separate file would be great
not sure in what order files stored in DWD, wallet archive should be first one small file (megabytes size) at the beginning of data
send me steps in private how partiton was mounted
the only explanation why it is not standard ISO format, DWD was used as bootable system drive for both unix, windows before data storage
