Yesterday I took my laptop apart and cleaned it. Have seen that I have 2 times 1TB memory. Then I have when I built the PC had again looked in the system data because there are only 1838 gb Available… Someone ne idea what is with the Knapp 200gb and how can I bring them?
That's because it works there with two different units. Windows does not expect Gigabyte but Gibibyte (even if they then write Gigabyte). By this other unit comes this displayed "difference" of about 200GB.
There are different units of measure for storage space.
There are GB (Gigabyte) and GiB (Gibibyte) among others.
1GB has 1000MB and 1GiB has 1024. - Basically everything is correct with you. - Only the Windows will show you GB, where GiB would be the more appropriate unit of measure.
Not at all, because this difference comes from the different counting methods of hard disk manufacturers and the count in the operating system:
Hard drive manufacturers:
1000Byte = 1kB, 1000KB = 1MB, 1000MB = 1GB and 1000GB = 1TB.
The calculator works but binary, and counts as well:
there are only 1024 bytes 1 kiB (often just kB written,
then 1024 kiB = 1 MiB, 1024 MiB = 1GiB, 1024 GiB and 1024 GiB to have a TiB, so the imprintedb numerically counted terabytes are just gross - including what the naked file system already proves is actually "only" 1852 GiB
So you would have to have 1099511627776 byte space available, so that your computer displays a complete terabyte, but the hard disk manufacturer delivers "only" 1000000000000 bytes of space, of which then also the space for the partition table and whatever in each file system heist, the "table of contents" in which is stored by the respective addresses are stored, which occupy the files. And this is saved several times for safety.
The notation GiB instead of GB actually indicates that binary was counted here, as with memory modules. Therefore, SSDs should actually be counted like that. So then a 1TB SSD should actually have gross 1TiB space. However, here also a whole number of memory cells are lost as unusable, so as to have reserve memory cells available when the memory controller detects damaged (worn) memory cells.
