LSD is a very intense experience, like a roller coaster ride. It produces stunning hallucinations though. It allows you the maximum control over your brain. You can change colours of your surroundings at whim and you ‘get vibes’ in this too but it takes a lot of mental effort to handle LSD. You can get uncontrollably paranoid or get stuck in negative thought loops. Not recommended for inexperienced people. I lost my phone the first time I did it. Cocaine fills you up with confidence and bravado. It makes you feel invincible and all powerful. You feel like you are always right. Even when you are wrong. You feel like doing more and more cocaine. And you get unlimited energy. More than MDMA even. Never drive on cocaine. And never carry a wallet full of cash. The cash will vaporize.

It depends on the level and type of damage. If the hard disk was physically damaged, it can hardly be repaired, but for some rare cases. And this can only be done by some technical experts and should never be done by yourself.
If the hard disk failed, but is not physically damaged, so it can still be detected, then you deal with a logical mistake. Therefore, you only need to get the data from the disk with some data recovery software.
