Please introduce the following. I have a 32 GB micro SD card. I put the thing in the computer / laptop and co, the card is only about 29 GB in size. That is clear. It needs space as a driver.
32 GB (size) - 29.71 GB (storage) = 2.29 GB (driver)
Is there a rule or percentage that I can use to calculate this?
Better said, how much driver does a 4 GB card use / how much is available?
The conversion from gigabytes to gibibytes do you mean?
4GB = 3.72529 gibibyte that has nothing to do with the driver only with the conversion 1024 to 1000
This is due to the conversion. One byte is 8 bits.
It needs space as a driver.
No it does not…
The "problem" is that Windoof (or microsuck) simply does not get it on the line to correctly implement a standard that has existed since the beginning of 1999.
Simply take the size in Gibibyte (GiB) and clap the unit gigabyte (GB), which has always led to confusion of all kinds.
The memory card has exactly 32GB (gigabytes).
That is 32 × 1000³ = 32000000000 bytes.
Now Windoof takes this size and converts it to Gibibyte (GiB):
32000000000 / 1024³ = approx. 29.802322387695312 GiB
And now comes the key point: If you take this size and just put the wrong unit behind it, the whole thing looks far less than it actually is.
P.S.: This is roughly the same as if you take a 32 yard (1 yard = 0.9144 meter) rope and label it with "32 meters". Then you have "only" 29.2608 meters when measuring. Where are the "missing" 2.7392 meters? Quite simply: there are no missing 2.7392 meters. What is there's a tünne that labeled the whole thing with the wrong unit.
