    Hi all,

    I have recently purchased the HX510, and it seems to be a superb machine. Just one query - not sure if anyone might be able to advise....
    When I record things to the HDD it tells you how much space is left in the top right hand corner of the "Title List" menu. However, having completely cleared the HDD last night (i.e. nothing left on there) it claimed that only 79.4GB were free and not the full 80GB. I know this is only ridiculously small amounts, but I would hope that it would just not keep decreasing. Any ideas as to what it could be?

    Thanks for any suggestions

    I would think you are unnecessarily worrying about what is a common difference between a specified and actual HDD capacity.......there will be some small files used by the operating system on it......or it is the way HDD capacity is measured.

    Hi,

    I suppose, this difference is normal. I own 710, but I didn't check what size of clean HDD were reported by the recorder. It is also possible, that recorder uses some little amount of disc space for system/information files. Anyway, you are right, 79.4GB is almost 80GB. I'm really not expect, it will be increase in the future. There is no reason for that. You have to know exact type of used HDD if you want to know exact size of it. And you should remember, that for HDD 1GB = 1 000 000 bytes.

    I thought 1GB = 1 024 000 bytes :confused:

    Not if you are a hard drive manufacturer.

    8bits (bit is 0 or 1) =1 byte

    1024 bytes =kilobyte

    1024 'cause computers use binary
    10000000000 unsigned =1024



    1024 kilobytes = 1 megabyte (1048576 bytes)

    1024 megabytes =1 gigabyte (1073741824 bytes)

    precise
    but manufactuers say 1000 cause it is easier with base 10

    they wouldn't sell you a 171.798691840 harddisk so it becomes 160 gigabye


    The space used is for file management.

    Normally 1 GB is 1 073 741 824 bytes, but for eg. discs manufacturer uses 1GB = 1 000 000 000 bytes. You can check it if you insert blank DVD disc, labeled 4.7 GB. It has almost 4 700 000 000 bytes of free space, which is trully 4.38 GB. Anyway, this is not clear situation, because blank CD-R (700 MB) has about 736 000 000 bytes of free space. Anyway, for each HDD manufacturer uses 10 based terminology. So, if you get eg. 80 GB HDD, you can store about 80 000 000 000 bytes on it.

    This is only unwritten agreement between you and marketing divisions!

    I think, it would help.
