Problem: the c drive is running out of space

Many administrators will confronted with the dilemma that the Windows Server 2003 c drive is running out space. With more and more installation of software and maybe backup files, a larger c partition is needed. Actually there are lots of people who are calling for help on the net. Let’s see their problems.

  • Hi,Can anyone help? I have a Windows Server 2003 and need create more space for 'C' System that has only 330Mb of free space left. Can I add space to this partition from a re-sized partition or do I need to copy the existing 'C' partition to the new free space of 12GB that I have created and then make the 12GB partition Active and Primary for Windows to boot.
  • Hi, I have got a windows server 2003 which for the last 3 years has been running low on space. Unfortunately, the monkeys who setup the server, only gave C: a 10gb partition, but with updates and essential applications, it leaves about 500mb. Which obviously soon goes down with logfiles etc. Does anyone know how easy it would be to possibly ghost the hard drive? Would it be possible for me to take a ghost of the hard drive currently on the system, and then copy it to a say 100 or 1000gb hard drive replacement? Or is there a way of re-sizing the C: partition?
