    1 GB Media Card really 1 GB?

    Advertisement



    I just installed my 1 GB San Disk micro card in my BB. Then I went to menu/options/advanced options/media card to see what my total storage capacity is. According to the display, my Total Space is 968.25 MB and Free Space is 906.94 MB. Should I have 1000 MB (which is 1 GB correct?)? So why did I lose 32 MB? Secondly, it seems I have used up 62MB of space, but I haven't installed any new applications, ring tones, music or any media. How could I have used up so much space? The only thing I've added are my address book contacts, but it's only around 50 or so. Any advice appreciated.

    Black Pearl,
    I believe part of the 1GB is used up for formatting of the card. I'm not sure about the 62MB of space but you can go to options/advanced/applications and delete all languages that you do not need and then take your battery out for 15-30 seconds. Then check you storage space again. You should see a change.

    Ive never checked a card right out of the box. I know when the card is put into a phone it creates folders. Maybe this is what is taking up memory?

    My 1gb card also says total space as 968.25. Formatting, I guess...

    Re: 1 GB Media Card really 1 GB?

    Media manufacturers tend to cheat a little when reporting the capacity of the disks, cards, etc., that they sell.

    Unlike the human world, in which 1KB = 1000 bytes, 1 MB = 1000 KB, and 1GB = 1000 MB, in the binary world of computers 1 KB = 1,024 bytes, 1 MB = 1,024 KB, and 1 GB = 1,024 MB.

    If you do the math, the actual values work out to be 1 KB = 1,024 bytes, 1 MB = 1,048,576 bytes, and 1 GB = 1,073,741,824 bytes.

    A manufacturer who sells a device with exactly 1,000,000,000 bytes capacity will market it as a "1 GB" device, when in fact it is technically only 953.67 "real" MB. In addition, manufacturers tend to round up a little so they will still report a device as 1 GB in size if it has more than about 900,000,000 bytes storage capacity.

    In your case, you are seeing 968.25 MB reported by your Blackberry ... which calculates such things as multiples of 1024 ... so in fact, your card most likely has a capacity of 968.25*1024*1024 or 1,015,273,226 bytes ... which the manufacturer will happily report as "1 GB" ... and think he's being conservative when doing so because he's sold you a little more than 1,000,000,000 bytes of storage space and charged you for only "1 GB".

    In addition, most operating systems need some space for the sake of faster access to the data (called "journaled file system" on modern OSes).

    On a Mac, you buy a 100 GB hard drive but you GET 92 Gig or so... - but this 92 Gig are quite fast if you´re searching something via Spotlight

    2gb is the largest card that will work. Do they make larger than that?
