DB corruption check

good morning, I am evaluating EMC to buy two licenses, but I’m experiencing a problem; every time I close my PC without closing EMC before, on the restart it finds database corruption, and starts an incredibly long DB integrity check…  I’ve used any other client, free, and no one has this annoying behaviour… Am I doing something wrong? have you any suggestion?  it is important to me to know this before to buy the licenses…
Thank you !!
