That did the trick! Most of my old files were successfully loaded. Thank you VERY much!

Hello, all. First time posting here... I've just completed the long task of transferring all my files over from the 8-bit world into the modern PC world using SIO2PC (a great little tool, highly recommend it) and I unfortunately lost a couple disks due to media rot leaving chunks of surface stuck to the drive heads. From what I gathered, however, only tracks 19 & 20 storing the VTOC sectors seem to have been wrecked, but the actual files are mostly intact, having successfully created an image of the damaged disk. I tried ascertaining where the files start and stop (usually marked by the actual filename like "D:FILENAME.BAS", followed by a character with a decimal value of "16". Now, I noticed that Individual files that had been successfully pulled from an image all start with three "00" characters and one "01" character. I tried adding this combination of characters to a couple of attempted file recoveries, and it improved their load a little bit (to the point of not giving me an ERROR 120, 21 or 19), but file listings (they're all BASIC files) are jumbled and sometimes crash the emulator I'm trying to run just by simply typing "LIST" to view the source code. It's quite frustrating and I fear my data on a couple of these disks may be permanently lost. So I guess my question is this - is there a way to manually extract files from an image, assuming that their sectors aren't fragmented? Is there a tell-tale sign letting me know where the physical file start and end is? Many of the files I'm trying to restore are old personal demos that are irreplacable and there are only a small number of them. Any info appreciated. Thanks very much in advance!
