hi boblink,
if you can confirm how i see your drive situation.
you have one drive
your main drive contains the system partition and six others and is working ok
but shows a primary EISA partition 0f 18.06 GB that you want to convert to free space so that you may add it to you backup drive
firstly the EISA drive partition is your hidden system recovery recovery drive ( is this by any chance a dell machine?
although others do use the same system)
due to the lock on the special EISA partition Disk manager in windows will not touch it, nor will many commercial programs.
the first thing to try check your system documentation is see if you can invoke the partition from the initial boot menu before windows boot, and if you are lucky you will be able to free the partition using the manufacturers utility, You may have to create restore disks to enable the option to clear this partition.
if this is not possible all is not lost if you have a look at the instructions
Here
hope the explanation is clear but if you have any questions please post back and ask them before you do anything.
also if you do go ahead with this deletion of the eisa partition then windows will not be able to merge it with your backup you should be able to extend the last partition (OneKey) into the free space. if you wish to merge or move partitions you will need to use something like Gparted.
If you do go ahead remember the essential three things to be done - Backup Backup and Backup
