My brother put my HDD with the cover opened on the gas stove and burned it for about 5 minutes before I found out, I have work projects on it, I also had backups but they are a few weeks earlier so I have made quite some progress since then.

there are companies that do data recorvery. you shoukd send your hdd to one to save your data. it may cost some money and not 100% that you get everything back.
