If the number of a bad sector on a spinner hard drive is known, is there any way to determine what is affected by the bad sector?

That is a very interesting question.

Files are stored on a hard disc in linked list format. Pick up the FAT file entry and you can follow it to each sector on the disc and determine what sector it is. I don't know if the file blocks are stored as a singly linked list or a doubly linked list. If the latter, then you should be able to start at any block and follow it back to the file name for that block. If the former you will have to follow each file to find out what blocks make up that file.

There should be a utility available somewhere on the internet to do this, but I don't know. I will do some searching. What OS are you using (you mentioned Acronis TI 8 so I am guessing it is something before Windows 7).
