Debug a disk problem

If you need to see what might be wrong with reading or writing to a disk, you can look at the debug file that ends in .disklog. This file is the disk log. It records the time of each byte read or written, and what instruction was executed to perform the operation.

Each line has "RD" (for reads) or "WR" (for writes) to indicate what took place.

You can also find the physical encoding of a disk image in a debug file that ends in .physical.

When debugging anything, several other files are helpful:

• the metrics file (how many times certain events occur; ends in .metrics)
• the instruction log (all instructions sorted by place in memory it was executed; file ends in .asm)
• the timeset file (how much time each instruction took; ends in .time)
