Hi all,
I purchased Sandisk 16GB Microsdhc card, class 4
But in phone properties, it is showing as only 14.83 GB
Any solution to get full space of 16 GB?
Nothing has it full capacity, i have a 16GB Sandisk too, and it shows the same free space as yours, just get used to it ^^
Maybe there is solution friend, we have to trace out
And...why people dare to use different ROMs...i am very afraid to do things like that.., but interested those..
first of all if I have to install CM9...shall I need rooted phone ?
That is simple.
When you buy a SD Card or and hard drive or something like that, for an example, the 16GB it is in 16000000000 bits.
Since 1kb = 1024 bytes, doing the math...
16000000000 bits = 14.9011611938477 gigabits
yup, and is the same for every storage device, I also had a 16Gb but from Kingston and it shows actuall storage as 14.8Gb
1000 vs. 1024
When you see the space on a disk reported by the operating system (Android, Linux, et. al.) it is usually in units based on a kilo = 1024, commonly used by engineers who work with computers and digital logic:
One kilobyte (KB) = 1024 bytes.
One megabyte (MB) = 1024 x 1024 = 1,048,576 bytes.
One gigabyte (GB) = 1024 x 1024 x1024 = 1,073,741,824 bytes.
To make their products seem bigger, manufacturers use definitions of kilo-, mega- and giga- in the way they are commonly used in other disciplines:
kilo = 1000
mega = 1000 x 1000 = 1,000,000
giga = 1000 x 1000 = 1,000,000,000
Read the fine print on the packaging that comes with your flash memory card. Get a microscope and read it.
What, you threw that out one minute after you got home and didn't read the fine print!?!? Well, it's also on their website:
sandisk.com/products/mobile1-memory-products/sandisk-mobile-ultra-microsdhc-and-microsdxc-uhs-i-cards-for-android
Find the footnote marked by **. As you can see, the company is 100% honest. :angel:
So, when SanDisk says 16 GB, they mean 16 billion bytes.
But 16 billion divided by 1073741824 is only 14.9012. You are really getting only 14.9 GB (in 1024 byte kilobytes), and that is that the operating system is reporting. Well, you lost some space on the device that is taken up by formatting with FAT32, so that is why you see 14.83 GB, which is what I also get for my SanDisk "16 GB" SD Class 10 card. Read the footnote again. They never promised you could use *all* of the 16 billion bytes! You are lucky you got any space left for your data at all. Maybe they should say "up to almost 16 GB". :laugh:
I certainly won't defend the policy of SanDisk and other manufacturers. It seems to me that if they want to maintain a good reputation, a better strategy would be to deliver enough space that even after formatting, the device would initially show *more* than they advertise, not less.

would your prefer a SD or a MMC? Why?
:?:
MMC or SD
You can hardly buy MMC anymore. SD is basically the same thing, except some functionality is integrated that can assist in Digital Rights Management schemes. If you do not use the DRM functionality (by not buying any DRM controlled content), it won't do anything creepy behind your back, and it will basically be the same thing. If large enough MMCs would still be widely available and cheaper, they would be the preferred buy, I guess...
SD is much faster than MMC.
SD prices are coming down also. Look around. In the UK i found prices for a 256 MB SD card from 90 to 120 pounds!
I found a PNY card at watford electronics for 67 pounds inc vat and delivery. (savastore.com). Thats the cheapest i could find for a 256 Mb card. And its nice and fast too.
found prices for 256 down to 85 Euro's incl VAT (SanDisk)
DaneElec often cheaper than SanDisk, probably no difference in quality, but difficult to tell
There is also brandless stuff around
SLOW!
Be advised we found the Dane-Elec to be incredibly slow!

MMC judging by whats on sale seems to be limited to 128mb. And seeing as a 256mb SD is around the 60 squid mark, there is no umming and arring.
Looks like MMC is about to die, unless the product line can be brought back to life. The must be something fundamental wrong with it. Why would developments stop?

I have seen this question asked like 1000 times in various forms like
Android doesn't work on 32GB kingston card!
microsd card corrupt?
32GB kingston microsd legit?
Here is the answer for all of them.
Please do not buy Microsd cards from Ebay...there are only a number of companies which succeeded in making 32GB microsd cards. AND KINGSTON IS NOT ONE OF THEM nor those chinese brands which are available on ebay.
yes Kingston doesn't make 32GB microsd cards.
http://www.kingston.com/flash/sdhc_micro.asp
so be wise and do your research before buying a microSD card!!
EDIT: Kingston UK do make 32GB microSDHC cards. sorry for the confusion. But be careful anyways because there are duplicate ones out there as well!
I just bought a kingston 32gb class 6 micro sdhc but when ever i put it in my hd2 it just freezes up and as soon as I remove the card it works fine again.At first i though that it was a fake so I:
1)performed multiple tests,
2)reformated a 1000 times,
3)even putting 20gb of data just to make sure.
Turns out that it is authentic and it works perfectly on my girlfriend's htc BalckStone it also worked when I installed NAND (which i later removed due to insufficient memory).Ive been searching for days, I think its a windows mobile issue, any tips??
Kingston does not make class 6 microsd... they only make class 4. If it says class 6, then it's probably fake. It may still be 32gb, but it might be a cheap one or defective on that they are selling as kingston. I have a class 4 kingston 32gb that works fine in my hd2.
Son of a *****... I just ordered one from ebay and it should be arriving today... guess I will find out whether it works or not after work .. and of all listings, it was just a pic of the card itself and the damn thing said no returns... looked pretty shady but i couldnt resist 54.99 with shipping..
EDIT: after seeing the date which the OP posted this.. Im being a little more optimistic.. cross your fingers

Same problem. Looks like I got a knock off 32GB Kingston microsd class 4 from eBay. I can partition it into fat32 and ext2/3 but when I try to format the ext2/3 partition, it won't mount. If I only create a single partition either fat32 or ext2/3, it mounts and works fine. I'd stay away from knock off microsd's!
yeah mine was a knockoff too :/

This is worth it, take it from someone who was looking for something other than SanDisk 32GB C2 I have been waiting for Kingston's 32GB C4 for long time and when it came out I got it though offical site for $159.
Yeah, I ordered one of these last week from newegg along with an otterbox defender case for $33 w/free shipping for both.... not too bad at all. Should be getting them today. Has anyone used the Kingston class 4 32gb card for running android on the hd2?
Sent from my HTC HD2 using XDA App
Well, far as I know people do claim the R/W IOPs for HD2 when card inside the device won't go beyond class 2 rate but some who did use class 4-6 cards said they did see major improvement in terms of loading OS/Apps from mSD card. Anything beyond class 4 is an overkill on HD2 that I accept unless you are moving around massive amount of data and use HD2 as your mean to transfer it, in that case just buy thumb drive.
"Sent from my PC using THE hand" lol
I was in a Fry's Electronics the other day and I saw a 16gb Class 10 microsd card for $32.00. Don't remember the maker but it was not name brand, that is extremely questionable
wow
my videos which are about 12g play almost instantly now i love this card and the free usb reader, thanks kingston
Ya this card was worth waiting for hell I shot up an storm in this section comparing other vendors. Now I have the SanDisk 16GB C2 card not sure what to do with it, hopefully I can sell that cheap.
same
stuck with the sandisk
I ordered this 32GB class 4 card from Kingston and it is much slower then my old SanDisk card. Booting Android took over 5 minutes and after that the device still is VERY slow.
With its card reader I could copy my files onto it with 3-4MB/s.
Then I installed SKTools under Windows Mobile and used its benchmark tool to compare my SD Cards:
My old SanDisk 8GB card (stock one from the blackstone, afaik class 2): ~6,6MB/s reading and 1,1-1,5MB/s writing
The new class 4 32GB Kingston card: ~2,2MB/s reading and 500-700KB/s writing
So I can't use Android with this crappy SD card.
Ya IDK man same on my end. Took me 25min to traf 320mb files, ATM showing me 116min to traf 4.1gb.
i got kingston 23gb class 4. really disappointed takes forever to transfer. but speed test shows its class 4.
http://forum.xda-developers.com/showthread.php?t=861232
oh yeah i got the one from frys it rocks to bad its not 32gb.
I would stick with SanDisk.
I wanned to try out a faster card so got a class 6 Kingston 8gb.. while it loaded things faster, it caused severe stuttering and lagginess at times.
Upon reserach i found, kingston, and many other cards are not the same quality grade as sandisk, i am told in order to be price competitive they buy crap from others at cheap and stick thier name in it. And sometimes they buy rejects from sandisk, toshiba, samsung etc and brand them.....
Unfortunately i cant remmeber the links i researched....
So i would stick with sandisk, or another proven manufacturer....
UThis is total BS, I started it at like 6PM and now its 10:40PM and still 78min's to go WTF and its just 4.2GB music files avg at like 3-6mb/ea. Now I remember putting the whole dir in SanDisk 16GB Class 2 in less than 40min. So WTF does it take so long? Also as I wrote to Kingston CS ill share it here.
To make the file transfer go faster you have to directly allocate the file in memory thus saving time for R/W IO access. I did test many times but I am not even sure HD2 is following SD 2.0 or is it just this POS card no were close to even the stock SanDisk's.
Test: Dir with 5 files at 5mb/ea so thats 25mb. If you copy each file you reduce the time by 3x but if you copy the dir all the objects inside takes time to allocate for some reason.
PS: I am thinking about now getting SanDisk 32GB Class 2.
***UPDATE***
3.85GB

--------
SanDisk 16GB Class 2 = 26min

I also don't understand this.. I have a 16gb C2 card and wanted to experiment a lot with the various android roms out there, so thought a C4 would be the answer. ordered a 16gb C4 and it is always slower than the C2. a full 30 seconds on booting Android.
This confuses me.....okay okay .. thats not hard to do, but as far as I'm concerned if a card is rated at twice the "constant" speed of the other .. it should be faster...

I think it really depends on the card and not the class. I have a couple of Class4 and Class6 cards with identical builds of android and my class2 16gb continually outperform them in boot times and general speed. Class only designates write speed and there is a lot more to an SD card's performance that is not captured in the class designation.
ATM I am thinking about returning the Kingston 32GB C4 as I spoke to Kingston Tech Support and might go with SanDisk 32GB C2. Alot of people say SanDisk is superior and is faster for some reason and getting close to class 4 rating.

I can only quote my experience and that is that kingston C4 is NOT fast at all.
Good luck to you.. and if you find the San Disk C4 is sooo much faster than the C2 can you report back please .. ?? So I can go get one

LOL you are way to funny man as you said "I just bought a kingston 32gb class 6 micro sdhc" and then on top of that "Turns out that it is authentic".
I am guessing you got this card from eBay? If thats the case then its fake ill tell you why as there is no Kingston 32GB Class 6 card ATM. My best bet is you do extended data testing on it and verify the content to make sure its not corrupted. But if I was you I wouldn't do any of this as ill return that POS, why take chance with your data? Also NEVER buy memory cards via eBay or else you will be pwned with notorious chinese fakes.
But for those who actually thinking about buying the legit Kingston 32GB Class 4 microSD read below and think twice.

Yup. It is 16GB, and that appears to be split into:
800 MB 'RAM'
1 GB 'Phone Space'
11 GB 'usb storage'
Using my amazing mathematical powers, I deduce that excluding the silly 'GB rounding errors', we have 3 GB or so left over and that contains the OS itself. I am guessing about that however, it may be laid out in separate chips or something. It seems most likely that a 16 GB ship would be used, however, as 11 GB chips just don't exist.
Nothing new. I have a 4GB memory stick, and surely enough it's not 4GB, but it's 3.7 GB. My laptop has 500GB HDD, but it doesn't have the full 500GB, but it has 470GB. That's 30GB out the window.
I don't understand why they don't make it 530GB, take their stinking 30GB, and give me my 500GB
"The difference between units based on SI and binary prefixes increases as a semi-logarithmic (linear-log) function—for example, the SI kilobyte value is nearly 98% of the kibibyte, a megabyte is under 96% of a mebibyte, and a gigabyte is just over 93% of a gibibyte value. This means that a 300*GB (279*GiB) hard disk is indicated only as 279*GB. As storage sizes increase and larger units are used, this difference becomes even more pronounced."

While that is certainly true of hard disks, because of their arbitrary size, you will notice that all flash drives, and indeed all memory chips, come in 'set' sizes. Each is basically double the previous. In such chips the size issue you mention would not cause any difference, I believe.
I am pretty certain that this thing has a 16GB memory chip, but the partition for usb storage is just a partition of that.

Yes, it would. The maths is still the same, no matter the size of the device or its type. Like e.g. my 16GB microSDHC is actually 14.9GiB.
As for the OP: it is common for device manufacturers to report the whole amount of installed storage, even if that storage cannot be used by end-users. It's a simple marketing trick where the only point is to try to make it seem more than it actually is in reality. It's not technically lying, it's just not telling the whole truth.
Also you can quite safely assume that you'll actually be able to use only about 70% of the reported storage space, the rest is for ROM and such. It's the same thing for all of my mobile devices, including my Iconia Tab A500 tablet.
Actually, that is not entirely correct. Flash-based storage devices come with sizes in powers of two as, I believe, this is a consequence of the technology and of the manufacturing process.
Your example of the SDHC card is valid only because the formatted capacity is different and always smaller than the device capacity due to filesystem overhead. There is no units conversion loss here, it is a real one because you simply cannot have a filesystem without any overhead (remember that there is no free lunch).
Magnetic storage devices do suffer, however, from the misleading advertisement of having their capacity expressed in powers of ten, not of two. Moreover, there also is the loss of user-available capacity by the means of using a filesystem, so then you have a two-fold decrease in total user available capacity.
To cut a long story short: the Note has, indeed, a 16 GiB flash-storage chip inside. A part of this is reserved for the OS (about 3 GiB), another part is reserved for application storage (about 2 GiB) and the rest (about 11 GiB) is all for the user to fill up with her stuff.

2GBs are reserved for applications and 1GB is reserved for Android OS. The remaining two gigabytes are unallocated I think.
In short, everything is fine and every manufacturer does this.
There's a total of 16GB of flash memory.
Around 700M-1GB for /system
512MB for /preload
2GB for /data
??? MB (100-200) for /cache
A few small partitions for bootloaders/kernels
The remaining 11GB or so for /sdcard
Another 'trick' manufacturers use is to quote 1GB as 1000 MB (and 1MB as 1000kB, etc.) instead of the 1024s the OS uses. That way the quoted marketing says 16GB but you end up with less because of the inaccuracies between base values.
I.e. marketing: 16GB = 16 x 1000 x 1000 x 1000 bytes.
OS: 16 x 1024 x 1024 x 1024 bytes.

Actually marketed values are a true representation. The prefix giga means 10^9 so a gigabyte is 1 x 10^9 bytes.
But as already stated it's the combination of these factors that lead to what appears to be reduced space on the device. It's a good thing we've got micro sd slot
