Unallocated space created during installation

[mlrathore]

I have 80 GB harddisk, partitioned into 4 drives of 20 GB each. I
installed XP on the first drive. However after intallation was done
and a couple of reboots, somehow the partitions changed. The first
drive (C reduced to 12 GB and an unallocated space 8 GB left between
C and D. Now disk Management Console has actions greyed out on this
space. Any idea whats going on and whats the remedy

Is the disk make and size properly recognized in the BIOS? Are the
jumpers on the hard disk properly located? Is it the sole disk on the
controller or is it in a Master/Slave relationship with another disk?
Is the hard disk properly cabled, if it is in a Master/Slave arrangement
is it at the proper location on the cable? Other than the XP
installation does the disk (other partitions) contain any data that you
want/need to save?
