2 problems (battle ship) and turing erasing problem

[jasonhan416]

Problem 1.
Recently i was saving my stuff on my usb file and some of my turing files code either goes missing or comes out with bunc of gibberish.
It happend whenever i copied and pasted the picture that crashed >_>.
Now, even though i erased the pic that crashed, still some of my turing files gets to be in blank or gibberish.
Can anyone fix it?

Problem 2.
I am trying to make an battle ship game for an ISP.
Is it possible to drag the ships (bunch of boxes) into the grid paper and make it work?

1. When disconnecting your USB drive, do you safely disconnect it from the machine (tell it to unmount or "Safely Disconnect" the drive) or do you just yank it out?

Always safely disconnect. Your operating system may defer writing to the USB drive, or the write may take some time. Safely disconnecting before yanking the drive prevents you from pulling the drive while you're in the middle of a data-write (which could corrupt data).

Sadly, if this is what caused the problem, there's nothing that can be done for your files, they're toast. Look around to see if you have backup copies on any computer. Consider learning about proper revision control systems if you're going to continue with programming.

2. I have no idea what you're talking about. You need to be clearer and more detailed about what you want to do.
