My teacher was explaining how hardrives worked by writing to sectors and how files aren't completely gone untill the sectors that the file was on is overwritten.
The entire class period I knew everything that he went over.
Then he brought up this concept that if a computer is turned off, instead of being properly shut down. Then the data that is loaded into memory is somehow written to the hardrive and some files can be "cross written" and become corrupt.
Anyway, he used the term Crosslink. I'm assuming that by memory he is talking about the page file. I always thought that as soon as power was removed the ram was emptied. Of course if this happens then how can anything become corrupt if the hardrive doesn't have power to write too sectors.
I tried to search it on google but came up with no results. If anyone has heard of this happening before or has any idea what my teacher is talking about, some insight would be greatly appreciated.
