I bought a new larger hard drive, formatted it in Windows and cloned all of the data from the old drive to the new hard drive. All is well, all went great, but now there is a primary partition and I have over 400 GB of unallocated space that I cannot get to. I went into disk management to try partitioning it but there was some type of error and it would not complete the task. Could not find the system event log on my PC anywhere, to get details of the error. Any suggestions??
