Linus,
NO, The MBR/GPT does NOT contain the File Tree Structure.
The MBR only holds Data about the Bootloader (if installed there) and the Partition Layout (Part. 0 starts at sect. 1, ends at sect. 1337 has a XFS/HFS/Ext4/ReiserFS/Whatever File System and Flags Alpha, Beta, Delta). GPT works similar.
Your actual directory tree is stored in the File system.
Second: Anything that can trigger an ATA Secure Erase will do the same as the manufacturer's tool (as long as Secure Erase is supported by the drive).
So, a Free tool for SSDs:
hdparm on Linux (USE WITH CAUTION!): https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase
Securely erasing data from a PC running Windows? Sysinternals to the rescue: https://docs.microsoft.com/en-us/sysinternals/downloads/sdelete
I don't know about other platforms.

TheSebware got a reaction from rhyseyness in What is this?
This is a frequency COUNTER, basically a device to measure frequency.
They do have a ref. oscillator (mostly 10 MHz) which controls the gate time, which is the time the counter takes to measure. The longer the gate is open, the more precise measurements you can get.

TheSebware got a reaction from mstr_maker in Need your help with mic guys.
use a dynamic stage microphone with a super-cardioid pickup pattern (e.g Rode M1-S) and a soundcard with a professional input (IOW: XLR, e. g. Behringer XENYX-USB series of mixers)
To get any useable level out of dynamic stage microphones you have to eat them.

There are no silly questions. Especially sb. who never did this before has to ask!
You turn only one channel up during the trimming phase (also called "soundcheck"), adjusting ONLY the gain knob. Level and Master stay at 0 during the trimming of that channel. When you trimmed the channel, you may not touch the gain knob, but every other knob.
And you're right: If you're only using 1 channel, there is no point of turning it off again.
Using the line In is (unless you're using studio grade cards) a bad Idea: Behringer puts in their XENYX-Mixers studio grade soundcards. Maybe not as great as an RME Fireface a friend of mine uses for live CD production, but unless you have a matched pair of microphone valued 10.000 € EACH, you don't need that.
But those onboard soundcards can be tossed in the trash. They never can give you the performance of a "real" soundcard.
Also you don't have (unless you're using studio grade cards) only asymetrical inputs. Avoid them!
Mute is minus infinity. 0 is "do nothing", as in make it neither louder nor quieter.
And keep your eye on the level meter! Clipping is bad. Your Mixer (it is an analog one, even if it's got a soundcard in it) is analog, so the right level is at around 0 db, on the digital side (your PC) you have to look, that they are at around -8 db, or you live in danger of clipping.
Another tip: Use headphones! If you send the microphone signal to speakers, it's fairly easy to get a feedback loop, which sounds like a very high, rising volume tone.
Men are even easier hit by this, as you have to boost the high bands to get a nice sound.
Also important: Experiment with your equipment. I can tell you what I'd do, but there's one thing where I explain it to you, and you actually trying it.
And don't be afraid of messing things up. The gear is so robust, it's pretty hard to brick anything just by playing with the knobs.
If you have an Android smartphone or tablet, get a 1/8 in to stereo RCA cable, connect that to the 2nd track and your phone, THEN turn it on.
Turn the sounds (apart from media, that turn up) of your device off and run the app "Custom Soundboard". That way you have a bunch of easy reachable buttons for playing out sound effects like a ding, a gong or whatever
As you got a dynamic STAGE microphone you need to get really close, to get any useable level out of it. Dynamic Mikes aren't as fragile as condensers, but are a bit harder to get to a decent level. Also it got a cardioid pattern, which means you have to talk directly to the front (opposite side of the XLR on that microphone), or your level will drop pretty fast.
Also: Turn everything off that you're not using: that means Gain to the minimum and Level to - infinity.

1. The less components between your Mixer and your PC the better, so DITCH THAT DAMM HUB!
2. Now to wiring it all up:
Use only SYMMETRIC connections wherever possible! That means: Microphone connection: 3-Way XLR ONLY. Other Sources: 2x TRS. That allows you to get rid of noise.
I can explain it, but it's rather technical and doesn't matter. And RCA-Connections ARE FRICKKIN ASSYMETRIC!
If your Mixer has an USB-2 Port, plug it into an USB-2 Socket. Yes, you could technically run USB2 on an USB 3 port and vice-versa, but it saves you a bit overhead.
If you have Dropouts in the audio, use another USB-Port.
3. What makes me louder.
GAIN: DO NEVER TOUCH AFTER THE SOUNDCHECK!.
LEVEL: Live adjustments of that channel (e. g. Microphone)
Master: changes the Volume of the complete mix.
4. How to set up:
PLUG EVERYTHING IN, BEFORE PLUGING IN THE USB!
Turn Level and Master of the first trimmable channel (has gain knob) to 0 (may sound confusing, 0 means straight through without modification of the volume)
Turn the gain knob to the lowest end, then put sth. on the channel (e. g. speak with a normal volume in your microphone) and ramp up the gain until you see the 0-mark on the meter barely flashing.
Turn the level of that channel back to off (fully left) and trimm every channel this way.
That's Input trimming. Now you normally never touch that again, until the input changes (e. g. your musical friend wants to record some vocals)
By male speakers you need to turn down the bass (low) and push the Highs, by females exactly in reverse. How much depends on the speaker and your taste.
That 2nd track to mix-Button is not needed unless you're using 2nd track. If you pushed it in, push it out! (just adds extra noise)
If you have any questions left, please ask. I do audio on some hobbyist theaters.
