Well, I'm running the commands now. I guess its now copying over to the external drive, but it gives no indication. But that was the last command, and it is not set to put in a new command, so I guess its working. Its 15 GB to copy, I guess it will be taking a while.
I note, two minor modifications. I will name the partition Push Button Reset, as the original is named, rather than merely Push Button. Also, at the end, I want to take off the X from the partition, we already believe that will make it visible, and so I want that off before doing the restart. If wanted, I can always put it on later easily enough.
I first made an Acronis image of part 6 to the external hard drive. (That took about 10 minutes, and was done as a sector-by-sector image, which is slower. But that gives an idea of the time this adds to the overall imaging, something less than 10 minutes when done as a full disk backup rather than sector-by-sector because of bad sectors.)
I decided to use a 32 GB flash drive to move the files to and hold them while the partition is being deleted and recreated. I formatted it as NTFS. And afterward, if any issue with deleting the files from it, I can simply accomplish that by once again Reformatting it back to FAT32. I believe that reformatting will erase everything, including anything invisible.
So, that's it, it's now copying over to the flash drive, I think -- that's taking quite a while. I'll keep you posted.
