Chapter 7
Partition and Format Drives that do not Contain Windows NT
Follow these instructions for drives that do not contain Windows NT.
1. Create a partition equal to (or less than) the real storage capacity.
In our ongoing example, you would create a 12 GB partition.
NOTE
If you try to create a partition that is larger than the real
storage capacity, the format operation will generate this
message: Warning: NT was unable to complete
the format.
2. Format the partition.
The formatted drive is now ready for use. Assume for this example that the drive
is now E: and was partitioned as a primary partition. The remaining virtual
storage space (500 GB minus 12 GB) must be left unpartitioned. You can write
data up to 12 GB on the drive. Windows NT will not allow you to write beyond
12 GB and lose any data.
Partition and Format a Drive that Contains Windows NT
Sometimes it is desirable to have the network operating system reside on a disk
array. The advantage is that the NOS resides on a redundant drive.
Virtual Sizing can be used with a disk array that is used as the boot device and
also contains user data. The key limitation is that Windows NT only allows a
FAT boot partition size of 4 GB or less.
If the NOS and data need to be on a single array (and single logical drive), and
you want to allow for capacity expansion, you must create multiple partitions.
1. Create a FAT boot partition of 4 GB or less for the NOS, which becomes
the C: volume.
2. Create a second partition for the data, which becomes, for example, the D:
volume.
3. The remaining virtual capacity must be left unpartitioned, and is available
for future partitions as you add disk drives to the array.
