Hacking 1 Block = ?? bytes in the flash

[kwirky]

The system menu will tell you how many free blocks remaining when you add or remove saved data or channel. Anybody knows 1 block equals to how many bytes in the flash?

 

[SirTempest]

afair one block is 128kbyte

 

[kwirky]

So if I have 600 blocks left that means I only have 70MB of free flash space left?

Thats an odd amount:/

Not really, it's exactly 1/8 of a megabyte!

 

[computerboy]

I don't find it odd

This is correct there are 4096 blocks of 128KB making up the 512MB NAND its on wiibrew here

 

[tj_cool]

yep 1 Wii block is 128kb

don't confuse with gc blocks which are only 8kb each

(so 1 wii block = 16 gc blocks)

 

[Wabsta]

I was always wondering about this too, but now I know, thanks

Does "blocks" on 3DS are same size as 128KB ?

 

[DeadlyFoez]

The NAND flash device is divided into 4096 blocks of 8 clusters. Each cluster is 8 pages. Each page is 2048 bytes of data and 64 bytes of "spare data"

^^That is the definitive math there

 

[giantpune]

also, you can only store up to 8 different files on 1 block, even if they are only 1 byte each.

Thanx for that info. I had always wanted to know the constraints with the file writing to blocks.

prolly not. The DSi, if I believe, has a diff block size than the Wii.

To be really exact: 4096 blocks of 128KiB making up the 512MiB NAND
Also correct is: 4096 blocks of 128kB == 524288kB == 524.288MB

All of this (kB KiB, MB MiB) is normed since many years.

 

[Vague Rant]

Not really. The original terms remain ambiguous and are generally better understood in context rather than unilaterally based on a single definition which has never been imposed on all usages. It's clearer to say "512 MiB", but "512 MB" isn't wrong just because it's possible to use the wrong definition. It's like trying to say one or the other definition of "billion" is wrong (one thousand million and one million million are both valid definitions). Throw in lack of interest in/adoption of the new terms, and the situation is far less clear than "megabyte no, mebibyte yes".

*facepalm* You really don't know your numbers. 1,000,000*1,000,000 and 1,000,000*1,000 are NOT the same thing.

Anyway, let this thread fall down again because we all now that 1 block=ummm, looking it up on wiibrew, and...128 KB.

 

[Wiimm]

There are 2 definitons of billion, trillion, quadrillion, ...

long scale (e.g. german): 
10^6  = Million
10^9  = Milliarde
10^12 = Billion
