I have 3 partitions on one hard drive. 43gb,55gb,12gb. When i got the computer i had two 55gb partitions only. I would like to know how to ''put'' the 12gb partition back in the 43gb. I would also like to know if there is any chance of failure and what might be the chances of failure and the consequences

Thanks in Advance.
