Title: sd card help
Post by: nymph4 on January 13, 2011, 10:23:20 AM
I have Match speed trio 5000  and got a Micro  SDHC card for it  and it is  16 BG

Wen I insert the card and format it it formats it in fat 32  and nothing els  I have win xp pro.

Wen it formats the card I go to properties and the capacity of the card says
14.8 GB

Why not 16 GB  it just was formated?

Were is my 2 other  GB?

you've already had this explained to you.

the 16GB on the box of a Hard drive or flash drive refers to a GB as 1000MB. The computer works in binary so a GB is really 1024MB, which is 1024KB, which is 1024 bytes.

so your 16GB drive is 16,000,000,000 bytes, which is 16,000,000,000/1024=15,625,000 Kilobytes, which is 15,258.7 MB, which is 14.8 GB.

Use Windows Disk Manager.
control panel > administrative tools >Computer Management >Disk Management

16GB on a box is using standard Metric amounts- 1000 as opposed to 1024. Therefore the actual size as seen by the computer will be different.

I think it was this part where the confusion was:  "...which is 16,000,000,000/1024=15,625,000 Kilobytes, which is 15,258.7 MB, which is 14.8 GB."
