Actually Hitachi sold HGST to Western Digital an American HDD company.
But if beer got into the small HEPA breather filter hole, too bad but if it just got on the circuit board. good news. low residue isopropyl alcohal and 24 forced air drying time will cure the problem. Beer has a dielectric constant due to water of about 60x air, which may cause crosstalk when on signals . If no click-click -click of death sound after startup, then Spinrite will fix it if the alcohal doesn't... then if neither works, buy a bottle of good scotch and douse your tonsils with it.
Then while waiting for it to dry. activate your spam filters on email.
Cap distortion is all about the dependance on ESR and voltage drop on change in capacitance with bias voltage. Y type Ceramic caps are the worst. COG are the best in ceramics for this attribute.
Old axial tanalums were high quality and many were rated for high rel quality when used in a design where the source and load impedance was greater than ESR ( such as audio applications , & filters or low current apps, but poor with ESR of cap was dominant in a high current app, meaning high ripple current and power dissipation and risk of thermal runaway.
Although never specified, all electrolytic capacitors can safely handle 10% rated V in negative bias.
(Note again.... "Electrolytics" includes ALL Tantalum wet or solid) common mistake to exclude them or say electolytics AND tantalum
