FTB using 100% disk space

[Damoz]

probably the wrong forum section, move it if you have to.

I was just wondering about this but when i run the larger ftb modpacks such as direwolf20 and monster, every now and then it starts lagging a lot (5-10 second long freezes) and on my task manager for windows 8 it shows it at 100% disk space and it still goes up in usage? im kinda getting confused with hard drive and hard disk space and i don't really know whats going on. my hardrive is 500gb when ftb is only reaching a high of 7-8mb yet this is making the 'disk' section go to 100%. I'm guessing that the two things have nothing to do with each other but if anyone could help me that would be great.

additionally my pc has only 4gb of ram, ive allocated 3gb to ftb. its 32bit yet i read somewhere to increease the amount of ram i could allocate i had to install both 32bit and 64bit java. Also my pc is quite old and is not a 'god' computer.

thx

You should only have 64 bit, not 32 bit java. And I would suggest 2.5 gigs to free up some RAM for OS.[DOUBLEPOST=1405233606][/DOUBLEPOST]

I never touched arguments, I believe @Qazplm601 does those.

thank you.

this appears to be a issue with your minecraft not being able to access your drive fast enough. this can be solved by getting an SSD(rather expensive) or, if you have a old computer, upgrading the HDD may suffice. i have not tried my args on this kind of problem before, you can test them, but i doubt they can help with the disk problem(will increase your FPS by a bit tho probably)

(these are slightly old, i am working on updating them)
also, 64bit and 2 gigs more ram would help a bit lot.

That^^^

Your hdd access is too slow, jvm arguments won't help I'm afraid....

thx everyone, it seems to go up to 100% only when its updating a lot of chunks and after I play for while in one area its pretty solid with decent fps and no freezes. getting a new pc sometime this year cause this ones like 7 years old . btw ill try those paremetre things

This. Make sure you are running 64-bit OS and Java, and also make sure you have enough RAM installed to allocate about 2-2..5GB for the client's use while leaving at least 1-2 GB for the OS to breathe naturally. (About 4GB for Win7-8, total).

When you see "Disk usage 100%" it doesn't mean your disk is 100% full, it means that there isn't enough RAM for the application to run without having to load a little piece of the program, do some calculations, write the results to the disk temporarily, load a new batch of data, rinse and repeat.
