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.

[@mateiberatco500]

Head size has nothing to do with sector size. Heads fly over 1 bit at a time (it's size is related to bit density only). The higher-level electronics (microcontroller) divide those bits into logical sector sizes. For each "sector", it also has to store headers (which are factory written, mentioned in video) and ECC data (error checking and correction); which all take space. Raising sector size from 512 to 4K means eliminating ECC and headers of 3 sectors, while slightly increasing ECC data for the 4th. But creates compatibility problems (mainly slowing down) with partitioning of old SW (up to, including, XP). PS: those 3.5" 1.44MB (1440MB) floppies were also advertised as 2MB unformatted. Wikipedia mentions formatted size for Amiga as 1.760KB.

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.

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.

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.

[@luhgarlicbread]

Do you know if it was possible to low level format a floppy disk outside of the factory?

[@juliancarter557]

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.

[@Shermanbay]

Another way of looking at low-level formatting is that the original write head is positioned by physical location, then it writes the address that defines the location. Simply put, at the location for track 1, sector 1, it writes "track 1, sector 1" , then "track 1, sector 2", then "track1, sector3", etc. The higher-level software of the OS then relies less on the physical head position and more on the written data to confirm its position just before reading or writing subsequent data. If it didn't do it this way, it would be all to easy to make a positioning mistake and store data in the wrong place, overwriting something else.

[@tutacat]

This is also the reason you should use file or disk encryption. When you delete an encrypted files pointer, and the encryption key is not compromised, then it is functionally the same as being raw formatted.

[@kennystrawnmusic]

Found this video a bit late but one thing that should be noted about SSDs is that they’re organized in pretty much the exact same way that RAM also is these days. Just as SSDs are organized into pages, so too is RAM and most modern CPUs have recursive page tables to map memory addresses the same way that an SSD’s mapping table is able to translate virtual LBAs to physical addresses of SSD pages. Since operating systems always have to design their own heap allocators to map the RAM, it should go without saying that mapping an SSD should in theory be just as straightforward. I say this as someone who has studied both the OSDev Wiki and Philipp Oppermann’s tutorial on writing kernels from scratch extensively.

[@wot_hog]

[@mikegallegos7]

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.

[@andyp5899]

[@TheStiepen]

One reason why low level formatting is no longer available is because it actually needs to be very precise, especially with higher data density. The formatting still fades today, but that is offset by it being much stronger and also better manufacturing. You used to access sectors on a hard disc using a CHS tuple (cylinder, head, sector) back with IDE. In fact on very old devices you actually had to tell the BIOS how many sectors, cylinders and heads (usually platters * 2) the disk actually had. nowadays with SATA (and NVMe as well) we exclusively use LBAs, which basically just gives each sector a number. One optimisation an HDD might do is switch between heads for every sector, which further improves sequential read/write performance. Fun fact: the MBR (to the extend of still being used) still contains CHS tuples for each partition. And yes, even GPT disks usually contain an MBR, though it's mostly useless.

What a great explanation!

[@kingzach74]

Joe, I think you got low-level formatting a bit confused. Low-level formatting used to mean something different than what it means today. Below is the history of low-level formatting. Initially, the term Low Level Format was used to denote a process of placing address marks on the magnetic surface of a rotational hard drive. A disk head used these marks to determine location of sectors. Such an approach was used in the days when disks were supplied separately from the controllers. Each controller marked a disk surface with its own incompatible labels. When moving a disk between different controllers it was needed to reformat the disk, i.e. to write appropriate address marks. Since circa 1994, disk vendors have been producing disks with built-in controllers where sector address marks are applied directly on the factory. So Low Level Format doesn't apply to the modern hard disks. Nowadays, the term Low Level Format is preserved and most often used to denote a process of filling a disk with zeroes. Modern Low Level Format In modern life Low Level Format is performed to fill a storage device with zeroes which results in the following: irreversible data destruction; reallocation of suspicious sectors; improving of write performance of SSDs which do not support TRIM. Still, TRIM is far better option for SSD maintenance. They say that it has sense to zero-fill the entire disk in case of a logical filesystem failure. In fact, it is enough to just zero-fill MBR (a partition table) or GPT (for large disks) which are typically located within the first 100 MB. A filesystem doesn't require absolutely "clean", completely zero-filled, data area to work in - it operates in a heap of rubbish easily. This is because a filesystem driver never reads what it didn't write.
