I've searched the forum for anything on this with no luck.

I just bought two 128MB Lexar Memory Stick Duo cards on eBay and my phone says they are 124MB with 123.5MB free.

Is this typical? Is there some way of formatting them to 128? The file manager in SMAN doesn't see any files, just the usual folders (video, audio etc.).

Even if anyone could direct me to where this was discussed before I would be happy to read it.

yeah thats normal with memory sticks/cards.

for some reason manufacturers call a megabyte 1000kb rather than the expected 1024kb so your 128MB card is actually 128000kb so divide this by the real 1024 which the phone does and it comes out to 125mb. Then takeaway the overheads of the fat table etc you are left with what you see

edit: and actually the reported size by the manufacturer isn't exact anyway. for example my sony duo 128mb has 129,695,744 bytes which equates to 126,656kb which equates to 123.6875mb

Thank You.

Surely that's false advertisement. Where else does 1000KB = 1MB? Maybe if you were explaining memory to your little sister, but not on an over-priced accessory product.

Ah well, I got it cheap on eBay

it gets worse as you get bigger cards. my 1GB SD card has its total capacity shown as 968.25mb on my iPAQ!

wipidoo a few mb, I guess it is false advertisement but will it really affect the purchase?

Computer Speak:

1000 kb = 1024kb or 1 meg.

Telecom Speak:

1000 kb = 1000 kb

False advertising? No.

This has been a age old problem. The problem basically originated decades ago when hard disk storage was new and costly. That was the only persistent storage available at that time. And probably to woo the market, the disk manufacturers came up with 1000kb = 1MB

This was not wrong, since 1 kilo = 1000; 1 million = 1000,000
However, it did not match with the earlier logic of 1kb = 1024 bytes prevalent in computing industry. This non-metric equation was a result of the limitation of binary algebra used in computers which always allowed to address numbers which are powers of 2. Since 1000 is not a power of 2, the nearest one (1024) was called a kilo. Hence, memory addressing still remained in 1024 units (like RAM, processor cache etc)... while storage followed true metric system.

...and the legacy problem still confuses us all

It also follows in Hard drives, but I know if you look at sonys site and most others when you look at a product like a laptop, it says in fine print at bottom, 1gig = 1000mb. So they do tell you.

It kinda sucks, but thats how its always been.........
