Case sensitive volumes

I have no cllue on how to change this, after using tech tool i lost one of my HD, but this has happened before. Not with tech tool though, i mved the jumper setting, i have 3 drives in there now, one is partitioned...(MAxtor) any ides on theses 2 problems?? thank you sooooo much it is becoming a pian ITA:radioacti

What is your actual problem?

well here is my problem....

1- i think i am having trouble on setting the jumper settings (4 hard drives but lets go with 3 for now)

2- I was installing WOW and it said that the Volume was casae sensitive, but it might be the installer, apparently it might be because i partitioned one hard(or did i) i have 3 HD showing but should have 4(due to the partition)

that should do it for now...i hope, thank you for your input!!
