Discrepancy in Reported and Actual Size Capacity
Q:
I have a 750GB HDD, why does the RAID only recognize the HDD available space as less than
750GB?
A:
Many customers are confused by their host system when it reports a discrepancy between
reported capacity and actual capacity. Several factors can come into play when your host
system views and reports the capacity of a hard drive. There are actually two different
numbering systems used to express units of storage capacity:
Binary: provides that a kilobyte is equal to 1024 bytes; and
Decimal: provides that a kilobyte is equal to 1000 bytes.
Capacity Disclaimer
Actual accessible hard drive capacity will indicate up to 10% lower than stated under different
Operating Systems and formatting.
The storage volume is measured in total bytes before formatting. References to round
numbers of gigabytes or terabytes are an approximation only. For example, a disk drive labeled
as having 500GB (gigabytes) has space for approximately 500,000,000,000 bytes before
formatting. After formatting, the drive capacity is reduced by about 5% to 10% depending on
the operating system and formatting used.
Q:
I would like to format my hard drives with the FAT (a.k.a. File Allocation Table) format, which
can be read and written by both Mac and PC. Is there any limitation on its capacity?
A:
Yes, please check the table below for reference.
