I recently noticed that there is no cap on disk labels(from misinterpreting a suggestion :)/> ). This can be used to store any ammount of data with a single disk. I've stored up to 7.3MB and counting so far without a problem in the disk name. I think it should be capped to 64 characters or something max, or else this will get abused.

You got me an idea for a new program…

yeah, don't store data this way, it's sure to be patched. You're right, it's hilarious that they overlooked it, not realizing floppies have infinite storage capacity because of it

There is a hard limit at some point. Possibly around (2^31)-1 bytes. But I believe it is stored in NBT so it's likely the max value of a signed short. Or approximately 32 MB ((2^15) - 1 for a 16 bit signed integer [short]). If I am wrong it's beyond ridiculous…
Edit: Confusing my words, I was wrong but confusing my words is even worse!

There is no limit imposed by NBT data, you'd hit a limit due to how much the string data type can store, so (2^31)-1 characters.

For those who want to see how much data that is, but don't want to do the math.
Spoiler
2 to the power of 31 = 2147483648
2147483648 - 1 = 2147483647
For these following calculations, I am assuming 1 character is equal to 1 byte.
2147483647 / 1024 = 2,097,152 kB
OR
2097152 / 1024 = 2,048 mB
OR
2048 / 1024 = 2 gBEdited on 11 August 2014 - 05:45 PM

Sorry you are right I was thinking of metadata. NBT would be a signed integer.

yeah having the limit be at metadata would mean a whole of two characters could be stored. so yes, definitely the cap is Integer.MAX_VALUE (since Java doesn't have unsigned ints).

This also applies to Computer labels.

So these too-often-suggested HDD peripherals (with gigabytes of data) were unintentionally added after all :D/>

It should be noted that putting enough information on floppies using this method could cause a crash. Once at least on lualand a floppy had a 200,000+ character label in a disk drive which when interacted with caused the player to disconnect and be unable to reconnect to the server.

What would you do with GBs of data in ComputerCraft? I don't think I've ever filled up a single disk.

I agree that GB is overkill, but several MB would be useful… I wrote a program once that in total was ~3MB in size. And I know that Oeed could make OneOS fill several MB easily.
