yeah when i got a 128 meg memory stick it was actually 123 i was thinkin of formating it again to see if it'll increase but i bet thats a waste lets calculate this 128*4=512 so if in my xperience i lost 5 megs multiplying that by 4 we get 20 megs so in a 512 meg memory stick the memory there shul be 492 hmmm now thats a rip off therefore buying 4 128 meg memorystick is even better

I got a movie 126Mb and wanted it to put on a 128mb duo, but it only has 123.5

The capacity of media is always displayed 'before formatting'. Formatting itself always reduces the available space. Because the formatting is done by an operating system the final result can vary across the operating systems. Therefore it is 'justified' to announce the physical memory space.

It has always been like that. Remember the floppy disks. A disk formatted vor DOS lost more space then one formatted for Apple.

So I wouldn't know why Sony should be the first to displat the amount of memory after formatting.

My only gripe (and it is a big one) is that on small memory card of 512 Mb, a loss of 44 Mb is bloody significant. On a hard drive (lets say 120 GB), if I end up with 114 GB it is not such a problem, as if I wanted more space I would just pay a few pound extra to get a larger drive in the first place.

This is not so easy to do with memory cards. Firstly they have not released the 1 GB version yet, and secondly it will not just cost a few pounds more to get this card.

I rest my case!

Well, even SD, MMC, and CF cards do this as well. It wasn't started by Sony.

And if you read the packaging on all memory products, it DOES state the actual numbers on the packaging (at least my MS Duo did)

I can understand how people are upset by this issue but its just something we have to live with. as mentioned, a mb can be one of two different values

if you are a my-symbian member there is a good thread about improving your effective capacity here

I have also done a few screen shots of some examples of cards I have

my Sandisk 256mb duo pro in my P910 shown as 238mb


my Sony 512mb duo pro in my P910 shown as 468mb


my 1gb SD card in my iPAQ shown as 968.25mb


my 2gb CF card in my iPAQ shown as 1952.69mb


I'm waiting on delivery of a 5gb card for the iPAQ so it will be interesting to see what that really is too!

Now I am even more upset.

44Mb loss on 512Mb - Aaaaaaaaaaaaagh

31Mb loss on 1GB - Not to bad

47Mb loss on 2GB - Even better

I don't even want to know the loss on 5GB card

Please also remember that the kind of filing system used makes a big difference in available memory.

FAT16
FAT32
NTFS

Are some examples of Filing Systems

All of them report different capacities on the SAME OS... depending on how the drive is formatted. This is due to byte cluster size of each filing system

I'm not sure how UIQ formats disks but I'm assuming FAT16.

Yes UIQ uses FAT16

Ya know.. The manufacturers actually have spec sheets on how much usuable memory the end user will actually have with these flash memory cards. It has never been a mystery nor have they attempted to make it so. The press releases for the MSD PROs actually include data on the speed, access memory, size, etc. all broken down on a nice chart. Just go to the manufacturer of the stick that you purchased and look up some specs. It's all there.
