[dipanjan86]

got myself a hp v165w 16gb pendrive yesterday.....now this 16gb sticker turn out to be 15 gb available when i plug it in...is this normal? also tried to transfer a 7.4 gb file into it yesterday and got the not enough space message...why is it so? went to HP - United States | Laptop Computers, Desktops , Printers, Servers and more and could not find any 16gb v165w .... although its available on flipkart.....have i bought in some duplicate shit??? please guide

1.free space will be 14.9gb,rest 1.1 gb is used in disk management. It is normal and happen with all pendrives.
2.file system of pen will be fat32,format it with ntfs,then you should be able to write that file.

ok .... actually i have a 2 gb pendrive that gives 1.92gb space in fat32....going by that logic i calculated i should get 15.36gb ...... anyways what of the other queries?

Well that significant amount of 1.1 GB is not lost in disk management. The thing is storage devices comes as GiB which they cite as GB. Difference is, GiB = 10^9 Bytes and GB = 2^30 Bytes.

The latter is a larger value.

Disk management do lead to loss of usable space but it is in MB hardly but not in order of 1.1GB.

guys i m getting confused.......and could any one tell me why this model does not show up in their site? is it fake?

[avtar2008]

THANKS perplexed for that info...

@OP: many of my friends have that model,so,i don't think you got a fake one. And flipkart is a reliable site, hey don't sell duplicate things.

[dipanjan86]

ok i m summing up ..... 16 gb = 16 GiB in case of pen drives = 16 * 10^9 bytes ...... = (16*10^9/1024) mb = (16*10^9/1024)/1024 gb ???

[The Black Knight]

Exactly..
That is why the total memory shown in Windows is ~14.9GB. And that 7.4GB file transfer error is probably due to the FAT32 limitations. Format your pen drive using NTFS and you'd be good to go. And as avtar2008 said, Flipkart is reliable, so don't worry...

[dipanjan86]

the above calculation gives 15258.78906 ........ something's still missing ...... can any one clarify ???? i think its the byte to mb conversion .... i thought 1024 byte = 1mb ....please correct me ...

[The Black Knight]

Dude that's 15258.789 MB. Divide it further by 1024 and you'll get 14.9GB, exactly what is being shown by your operating system...
