8G Microdrive only showing 7.43 G

Just received my new Seagate 8G microdive slid it into my card reader. When I looked at the properties of it in Windows to see what the actual capacity was. i\It only shows that 7.43G is available. There is nothing on the card, its blank. I know that you will almost never see the full capacity of any flash media. But come on, missing that much seems a bit ridiculous. I purchased an 8G card not a 7.43G card.

Does loosing that much capacity seen to be in the norm?

Is there any way to recover any of the lost space?

That may be accurate. I was checking my 512MB SD card, and it shows that newly formatted via FAT32 gives about 471MB of actual space. So, if you were to multiply the roughly 40MB difference by 16 to get your equivalent space size, you get about 640MB difference, so 8GB -640MB would give you about the same ratio. If I've done my math right!:)

Marketing 8GB != Real 8GB
Real 8GB = 8 x 1024MB
Marketing 8GB = 8 x 1000MB

Hi.

8 G card = 8*10^9 Byte = 7,45 GigaByte

8*(1000/1024)^3

FAT=0,02 GigaByte

Capacity= 7,43 GigaByte

The manufacturer reckons 1GB as 1 billion bytes, but the OS reckons 1GB as 2^30.

(1,000,000,000/2^30) * 8 = 7.450580596923828125.

The rest is probably the FAT.

Manufactures do lazy math rather than accurate math. :)

So what's showing is probably just about right if you use the same math the manufactures use. :)

Yeah all these formuals are sweet - people need to remember that this has been going on from the start. I remember buying my FIrst AST P1 and back then I was UBERNOOB -

Even before this mess, a lot of new computer companies had marketers that didn't even know these formulas. companies used measurement of 1047 - the KB size of a floppy - that then was reduced in thinking only to a mulitplier - people considered the floppy a measuring device - 1 floppy = 1 MB so even though all these formulas are correct - it never prevented some NOW DEFUNCT PC manufacturers from confusing us even more.

Example - "uh how big is this file? " it's 10MB * thinking that it took 10 floppies to span it . this is the crap we were forced to deal with in the 486DX and SX days

WOw I'm old now. LOL

PEACE

Bah, i got ya beat. I'm 20 and i spent several years (mid-late 90s) with nothing more than a 386, monochrome laptop! That was more of a, erm, "financially motivated" decision however...

Ha, i still use that floppy analogy when i'm raving about how amazing my new [insert storage device] is to my parents. "Think of it! It's like 1000 floppies in this little postage stamp!"
