Calculating disk capacity and max data transfer rate of a hard drive?
- Add the sectors together for a 120 cylinder zone: (200+240+280+320) = 1040 sectors.
- Since there are 4 cylinder zones, there are a total of 4160 sectors.
- Multiply the sectors by 4096: 4160 * 4096 bytes = 17.03 MB.

Why is my 500 GB drive displayed as 465 GB?
So a “500GB” disk has 500 x . 931GB of storage, or 465GB. This isn’t because your system isn’t showing some available storage or because the formatting lost storage – it’s just the byproduct of the disk manufacturers exaggerating the storage capacity.
What is TB storage capacity?
1 TB equals 1,000 gigabytes (GB) or 1,000,000 megabytes (MB).Compared to the average smartphone, 1 TB of storage is the same as roughly 8 (128 GB) iPhones or Samsung Galaxy devices. 1 TB is also about 4 (256 GB) Windows or MacBook laptops—and some storage space is eaten up by system software.
How many GB is 2tb?
TB to GB Conversion Table
| Terabytes (TB) | Gigabytes (GB) decimal | Gigabytes (GB) binary |

Why is 1TB HDD 931 GB?
However, to add to the confusion again, every OS displays this as GB (not GiB). In practice, 1 TB (1,000,000,000,000 bytes) is approximately 931 GiB (999,653,638,144 bytes). Your computer will then show it as 931GB. Because 1TB sounds larger than 931GB and it actually has a trillion bytes, it is sold as 1TB.
Why does my 500gb hold less?
In the binary numbering system, one megabyte is equal to 1,048,576 bytes, one gigabyte is equal to 1,073,741,824 bytes, and one terabyte is equal to 1,099,511,627,776 bytes. Example: A 500 GB hard drive is approximately 500,000,000,000 bytes (500 x 1,000,000,000).This is why Windows will show a 500 GB drive as 465 GB.
Why is a terabyte not 1000 gigs?
ALL data storage from every company for decades now uses decimal decimal notation in which one megabyte (MB) = 1,000 kilobytes instead of 1024 kB, one gigabyte (GB) is equal to 1,000 megabytes instead of 1,024 mB, and one terabyte (TB) is equal to 1,000 gigabytes instead of 1,024 GB.
How do I create an exact 500GB partition?

- Step 2: Convert your target to MB.
- Step 3: Convert to mebibytes.
- Step 4: Compensate for partition overhead.
- Step 5: Open the disk management MMC.
- Step 6: Launch the partition wizard.
- Step 7: Specify volume size.
How do I create a 200GB partition?
Quick Takes
- Open Disk Management and right click on the Windows 7 partition.
- Select the “Shrink Volume” option.
- I’m going to create 200GB of “Unallocated” for Windows 10, although 100GB is more than enough for all practical purposes.
- Click on the “Shrink” button after you enter the appropriate value for your hard drive.
