I didn’t get a new camera, actually just got some new lights, improved the lighting arrangement, and messed around with some camera settings. And of course cranked up the sharpen effect in premiere pro ( ͡° ͜ʖ ͡°)

"Have you ever wondered what _actually_ is going on" YES! ABOUT EVERYTHING! KEEP MAKING THESE VIDEOS!

Hi Joe! You might remember me as the author of Task Manager, but I'm also the author of the Format dialog! I have a video about it's history on my channel (Dave's Garage). Would have been a good topic to do a collab on! Cheers and the new Apature lights (I can only assume), looks good!

Sector size is a function of read/write head size. Block size can affect read/write speeds. In other words, it's faster to read ten 10 byte blocks than it is to read one hundred 1 byte blocks.

Got the notification while formating a 30Gigs drive.

Drink every time he says „I’m not gonna get into that“

Please never stop making these informative videos.

A trim command (known as TRIM in the ATA command set, and UNMAP in the SCSI command set) allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered in use and can be wiped internally. Trim was introduced soon after SSDs were introduced.

Not sure about everyone else but I really appreciate the extra details you provide in your videos. Thanks for not "dumbing it down" too much!

Perfect timing! I’m actually in the middle of formatting a 2tb drive to clean it of things I regret seeing

Yes, I've been using IBM PC's since the 80's, at that time the original hard drive controllers actually sat in a plug-in card attached to the original ISA bus (great-grandfather of all of the current generation of PCI buses). The control logic sat outside the hard drives themselves on this plug-in card. Now back then there used to be two different types of hard drive formats available, MFM & RLL, and so you had to get the appropriate type of controller card for the type of HDD you were getting. The low-level formatter was a piece of code within the controller card that you could execute by using a special program in DOS that initiated that portion of the controller's logic. That all went away once the IDE HDD's came, the controller logic all lay inside the HDD's themselves, and the smart "controller cards" actually just became simpler dumb interface cards. Low-level formatting also became inaccessible by that point, as the LLF was done at the factory, and never needed refreshing.

Before Vista a "full" format was just a deep scan over the drive for bad sectors & not actually writing zeros. Starting with Vista a full format does do the zero write.

This is a pretty good piece, I was already familiar with a lot of the stuff in isolation but you did a nice job putting it all together into an easily understandable package.

LL formatting was back in the day when a 10 megabyte drive was _something..._ back when most personal computers ran on floppys or tape and the user was the device driver for everything.

*finally finds a video where someone goes into detail about something no one ever goes into detail about so I can finally learn 100%* UKpostsr: I’m not going to get into that, I’m going to keep it simple for this video GOD DAMMIT 😫

This man's explanations are all over the place. Reminds me of how a child would explain things. No structure, no pacing or pauses, and lots of 'I'm not going to get into that'.

This is why i subbed to this channel Some stuff u wonder what they do

The way you've completey turned the channel around is beautiful.

Bro you need to like assemble the stuff into like a playlist teach everything about computers because you explain everything so well. You're literally a villain turned hero. Thank you so much for what you do

As a tech guy who helps people with their computer and is constantly into tech stuff, I was always curious about this and even though you said you went extra, always remember there are people out there who understand everything you said and I learned a lot from the video! Thanks for the education and I always love your content. 🤘🏼🤙🏼

I would love to know more about SSDs! You left us a bit short on them :D

This was the fastest, easiest 16 min video I've watched. Thank you.

Thanks for the explanation of hard disc and SSD style storage. The MVME on both the motherboard and on the SSD looks like a better strategy. brilliant.

I'm addicted to these videos! Very well explained👍

I had been looking for this video since ages. Very informative! Thanks 👍☺️

The detailed info about the drives makes the video very educational but still intresting. Keep it up! :)

Very educational! And surprisingly clearly explained! I'll be checking out more of your videos. Thanks!

This has answered a lot of questions about hard drives I really have I wondered about for a long long time!

Nice one, u bring to this platform a genuine approach sharing ur knowledge with others and create a supportive community. So long as u tell it as it is I'll continue to tune in.YES from me too

I'm surprised you explained all that shit and didn't bother with what NTFS and FAT32 are XD

Thank you for making this video. I learned a lot. And also I am now motivated to format one of my drives 😄

Awesome job explaining out things in detail for better understanding for all types of mind sets. You calling must have been a teacher or guide for others. Technical thinking is extremely important and very hard to find, especially these days. Never loose that moral spark you carry big dog. I definitely learned a lot from your channel and that's what it's about. GREAT JOB 👍

I had almost forgotten about low-level formatting. Seems that it took forever to low-level format my 30MB hard disk. I had the option to upgrade my Compaq 286 to the 30MB and all my friends thought I was nuts for paying extra for such a huge drive. "You will never be able to use 30MB on a home computer even 30 or 40 years from now."

Wonderfully technical! Thank you so much!

Just stumbled upon your channel and I started to get all the answers to my questions!

THIO you are amazing! Thank you, for your incredibly informative tutorials.

I learn a lot on this channel please keep these videos coming.

Very informative. I enjoyed it, however, the part that got me more glued was where you stopped. I'm using more SSDs now to create content and I was interested in the Open Channel SSD thing about NVME drives.

Your Videos are very good and helped many people including me. Keep up the good work!

Very interesting and informative! Thanks!

Good video Joe. An excellent crash course on how drives work.

This helps so much! I want to get an SSD and want to know what to do with the old hard drive, and now I know

Thank you for this informative explanation video.💡

@15:25 I would like a video on the NVME drive please regarding that specific process. I think it would be informative and interesting to the audience.

I love these videos so much.. Simply explained for everyone!

Nice informative video, I now have a better understanding of how and what my drives do … thanks 👍

ThioJoe reminds me of myself when I was younger - except he's really cool and has a youtube channel.

Very helpful information and indepth thank you

This is a very informative video, thanks so much!

Thanks for adding the time stamp.

Dude these videos are so informativ! I don't know any other channel that has tech content that is so unique as this one. Most channels just have the standard top 10 best gaming laptops or something. Not ThioJoe, this video and the System32 hidden programs video are so unique and high quality. The reason I am subscribed to your channel! Keep up the good work man!

You made every single second of this video worth . You constantly do on all of your videos though tbh . Cheers mate 👍

Thanks very very much. Now I understand. You present these subjects in a way that my poor old brain absorbs what you are teaching. Thanks.

Provisional explaining good work thanks

The way I recall "Low level formatting" was in the pre ATA interface days. The PC (usually DOS based Disk File System) actually completely controlled the hard disk. This also only allowed for logical drives of 32MB (yes MB). The Hard Disk Controller was plugged into an expansion slot on your computer and then you would use the dos debug tool to access a certain memory address to invoke the setup tools to partition and low level format your drives then allocate them as logical drives. I dont recall ever having to re low level format a drive on a PC XT or AT you merely set up the drive tracks, sectors and partitions once. Then you could return to DOS and format the drives. The ATA drives introduced the actual hardware control to the drives themselves and a simplified interface for the computers. So while you may use the DOS/Windows format command afterwards what physically happened on the disk was out of the computers hands as the ATA on drive controller actually took control and allowed for automatic management of bad sectors by swappibg bad sectors with a reserve of alternative sectors.

First time I watch one of ThioJoe's videos in the first 10 minutes.

That's the clearest explanation I've ever heard

Now I know what is the meaning of: *Size of actual file and size of file in the disk* while seeing properties of a file or folder😎

Thank you for a very informative and helpful video 😊

It's nice when a UKpostsr explains somewhat complex technical stuff in terms I can understand. Though with "zone allocation" it might be irrelevant but, I am curious how big is "Big files"( like, "text document big", "mp3 big" "Cd Iso" big, "DVD iso" big or such. )

Superb explanation, thanks!

That was brilliantly informative

That was some knowledge in this video!💯

What a great explanation!

Love the way you explain

Informative video. Your videos are suitable for computer class lectures. If a teacher is watching them. Can definitely play or recommend to the students. SmartTJ 😎

Excellent presentation!!

Fascinating information. Good to know.

Really great information Joe. Esp. on SSD

Thank you for this quality video.

Thank you for all this information

thanks for the lesson!

Back in the day, low-level formatting wasn't just an "apparently you could" thing. It was a "you must do this first" thing. My memory is fading a bit, but in MS-DOS, you had to run the DEBUG command (built-in to the OS) to access a piece of microcode to do the low-level format. The code was likely on the controller. Once running, you would put in the drive geometry which was printing on the drive from the factory. It said how many heads, cylinders, sectors, etc. there were on the drive. In addition to that, the drive often came with a defect map you had to key into the low-level formatting utility to remove those parts of the drive from visibility from the operating system. Isn't that something, a drive coming from the factory with known defects you had to work around. I don't miss those days. Once IDE drives came around, the controller was on the drive itself and the computer had a "host bus adapter" to be able to connect to them. I remember back in the day wondering why I'd want all these things integrated on the motherboard. What if one component fails? I'd need to replace the whole board! That's expensive and inconvenient! Now, it's not a big deal. The reliability of components is really good at this point with all the mistakes being made decades ago and manufacturers learning from them. With the advent of IDE drives, Zone Bit Recording became a thing so your drive geometry changed from a physical feature to a logical one. When the operating system asks for some data on this (cylinder, head, sector), the drive knows where it actually is and reports it back. Most spinning drives today have only one physical platter with one or two heads. Not like back in the day when it was common to have a drive with many platters and two heads each. My first hard drive was a MFM, 5.25", full-height (3") drive holding 30MB. I would next upgrade to a RLL, 3.25", half-height (1.5") drive holding 40MB which just happened to be a slower drive than the first one.

I learn a lot from U TJ So I just wanted to thank U ! and keep up the good vid's !

Useful info thank you

Now show us how to Unformat a Quick format! Keep up the good work ThioJoe. I am a long time fan!

Informative thanks

Some (if not many) Defrag programs will show the existence of the metadata files. Some will even display a name for each of them.

I remember LL Formatting (LLF) and that the reading arm mechanism was large and had density. That also meant the seek time was longer due to the read arm weight and that, speed, would wear out the reader arm. Thus, drives would fail and computer speed was limited from sluggish to not very fast. Therefore, when LLF became strictly a manufacturing process, reader arms became lighter, could move faster, reduced seek time, and thus computers got a speed boost.

Great explanation Thanks

Nice video: thanks for the help !!!

You are the best... Thankyou so much.. Thanks a lot...

Thank you, this was really great!!

Great explanation!👍

Thanks a lot this really helped

Cool. Thanks for sharing.

Okay this video was more useful than the classic "how to change the oil in your computer" from back in the day. Thank you very much.

Sweet, great video! Thanks!

You are very informing!!

Great video, I never knew what quick format does...

Joe, great video! Just curious if anyone remembers the old DOS command from back in the day, undelete or unformat? I ask as it was a simple dos command and not technically a forensic level software. I usually use dban or the heidi eraser software that was an experiment started by the university of California, and it works tremendously well as it even attempts to wipe the host protected area and other areas normally inaccessible by most software.

Always awesome content.

Absolutely wonderful🙌I love the fun facts😂

Awsome info bro!!

Thank you i finaly know what the defrag does after all this time, i used to think it just fixed broken stuff, now i understand it as organising data on a disc drive to make it quicker for the computer to locate information 😅 and that i never have to defragment again now all my drives are ssd

this video reminded me of info tech class where I was given a computer to troubleshoot. I can't count how many times I had to manually tell the bios how many cylinders, clusters, sectors there were on the hdd before I realized the cmos battery was dead lol.

Very informative

Thanks a lot for the knowledge you have been impacting into us.😌

thank you .. great video

Interesting thing: floppies and hard drives also have a sort of translation layer. It’s called sector skew. Sectors are not laid out in numeric order but so that, ideally, the next sector to be read is directly under the head when the previous action is done. This is set during low level formatting.
