MicroSD Card storage problems

I have installed Maverick on my Desire and I’m having problems copying files over to the SD card. I have made a map of my local area and there are over 200,000 files. When I copy the files from my hard disk to the 8gb microsd card I purchased the files inflate to a ridiculous size. I have listed the size the files take up on both the hard disk and microsd card. I know fat 32 and ntfs handle files differently, but surely the file size shouldn’t inflate that much.
Hard disk (NTFS)
Size 357 MB (374,469,968 bytes)
Size on disk 1.12 GB (1,213,493,248 bytes)
272,945 files 1,088 folders
8gb Microsd (FAT 32)
Size 308 MB (323,536,998 bytes)
Size on disk 6.94 GB (7,454,392,320 bytes)`
227,490 files 972 folders
I ran out of room on the microsd card by the way.
Any help would be appreciated.

8gb sd card actual size?

I partitioned my 8gb card before so I could use apsd and I don't use it anymore so I formatted my card and it still only tells me there's 6700 mb available.. I know some of the card will be taken up with software to make the card work but I didn't think it would be a gig.. did I format the card wrong?

if not the whole reason, most of the reason is that when the manufacturer makes their claim of 8GB, they are using the formula of 1000B being 1KB, 1000KB being 1MB, 1000MB being 1 GB, then when systems read the card, 1024B is 1KB, 1024KB is 1MB, 1024MB is 1GB...
so if the card is 8000000 Bytes claimed by the manuf. then 8000000/1024/1024 should be 7.6 gigs
my 8gig card shows 7.39 in my phone, so maybe the OS reserved 200MB for something?

If you partitioned your SD card for a2sd reformatting won't give you back the whole card. You need to repartition and select 0 for swap, 0 for ext and 'the rest' for FAT. That will repartition it into something your phone (and Windows/Mac/etc) can see and give you back the full available space.

FINALY Got the easy way to upgrade Streak 5 with internal MicroSDHC > 8Gb

After, trying many ways to upgrade my DS5 with Micro SDHC > 8GB, finally got the easy way to do it without modifying boot.rom or creating partition manually.
As we know that the maximum Gb can be recognize by DS5 is 8 Gb, higher than that should use modified boot.rom and also need some other step and autostart app to be installed. And the latest boot.rom I could get it is the boot.rom that work for streakdroid 191, I’ve tried for GS243 and it didn’t work (neither to make it work with streadroid 191) .
Here, I would like to share what I've found & how to do it. I use Micro SDHC 16 Gb cl10 for my internal SD, after several failures, then I decided to use Micro SDHC 8 Gb cl10 as for my internal SD. And, since DS5 are able to recognize 8Gb, the process is just simple as it is, just change the old SD card(2Gb) and plug the new one (8gb), start the DS5 and it will automatically create/format the SD with DS5 standard partition. And, DS5 work like the way it should be.
Then I made some experiment with my other 16Gb, I clone my 8Gb into 16Gb using Linux DD command. The process takes hours since DD copy sector by sector and duplicate everything from source to target. When the process completed then, I open both sd card using Gpart, and compare each other. The result is my16Gb has the same partition structure and data as in my8Gb + one remaining unallocated partition (because its size has bigger capacity).
My 8Gb:
1 Extended partition (8gb):
a. Small one partition (ext3) (around 250 mb)
b. Larger one partition (ext3)(around 7.7 Gb for OS)
My 16Gb:
1 Extended partition (8gb):
a. Small one partition (ext3) (around 250 mb)
b. Larger one partition (ext3)(around 7.7 Gb for OS)
c. Unallocated partition (around 8Gb free)
Next, I resize the extended partition on my16Gb to full capacity, apply it, and redo to resize partition for ext3 (the larger one) to max, apply it.
Then my 16Gb partition now has the same structure with my 8Gb (with two ext3 partitions) but with its max capacity.
1 Extended partition (16gb):
a. Small one partition (ext3) remain the same exactly like on a. of 8Gb.
b. Larger one partition (ext3) with maximum capacity of 16Gb.
(Note: the figure above is just to show you the changes have been made, I don’t have a screenshoot of both SD partition structure to show you exactly the allocated size composition).
Last step, I just plugin my 16Gb into my internal DS5, turn it on and,..
Walla,… it work like a charm, my DS5 can see my internal 16Gb Micro SD,..
I tried to install some application into it (push into internal SD via adb) and run it, and it work with no problem.
It might be also work for 32Gb, but I haven’t try it yet. (still enjoying my satisfaction,. )
Hope this can also work for those who want to upgrade their internal MicroSDHC of DS5 to more than 8Gb.
(I'm not responsible for any damage of your device and/or data lost from your SD card please do a backup of your system/SD card before trying to do as described above - especially when using DD command)

[Q] How to understand the result of H2testw

Excuse me,
I have bought Sandisk Micro SDHC, 32GB, class 10.
With the adaptor to SD Card (included), the H2test say; Error.
there is file *.h2w , on card, it mean not in writte protected mode.
So, i use Micro card reader, the first test:is:

What does it means?
***
I Insert to SGSII, with app: SD Tools, it says :

Please advise me, must I retour this Micro SDHC ?
Thanks

help.....

That means its ok.
If they say 1000mb tested and 800mb lost, it means that the actual capacity is 200mb. Hence, your micro sd card seems to have the standard 32gb capacity
HOWEVER, you were scammed. Class 10 sd cards should not have "Writing speed: 4.74 MB" It should be around 10MB
So yes, you should 'retour' your sd card. If you used paypal, I think you can get a full refund without having to send back anything as this is obviously a counterfeit item.

I understand, it is 32 GB.
And I have register the serial number to :

and no problem, they said: in warranty.
and test in my Samsung galaxy SII, with "SD Tools",
I Insert to SGSII, with app: SD Tools, it says :

I think the different speed may be because the Sandisk MIcroSDHC card reader, my Netbook (MSI U230, Windows XP SP2) or some thing else that may be not compatible with SDHC card.
because, in first test, i use the Adaptor to SD, insert to SD card slot in my Netbook: The H2testw said: Error. But with explorer, i can copy file to the card.
Then, i use Sandisk MicroSDHC card reader, insert to USB port in my netbook. And the H2testw said:

So, about the size (32 GB) and speed (9.1MByte/s) it is fine.
What I don't understand is that i bold.

SD Formatter 3.1 for SD/SDHC/SDXC
This software formats all SD memory cards, SDHC memory cards and SDXC memory cards. SD Formatter provides quick and easy access to the full capabilities of your SD, SDHC and SDXC memory cards.
The SD Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards. It is strongly recommended to use the SD Formatter instead of formatting utilities provided with operating systems that format various types of storage media. Using generic formatting utilities may result in less than optimal performance for your memory cards.
The SD/SDHC/SDXC memory cards have a "Protected Area" on the card for the SD standard's security function. The SD Formatter does not format the "Protected Area". Please use appropriate application software or SD-compatible device that provides SD security function to format the "Protected Area" in the memory card.

Is there a related between:

PS:
I have tested my 8 GB sandisk MicroSDHC class 4, on the same netbook and micro card reader:
[It is the memory card that i use in my SGSII, has many file, and only have space : 1,8GB ]
Warning: Only 1846 of 7561 MByte tested.

Tested - ADADTA microsd card
I bought a 32GB ADATA (upgraded) microsd card off Ebay.
It arrived in what looked like it's proper packaging but on the actual microsd card it said 64GB?
I did the test and the results are below - they don't look good.
Is the H2testw always 100% accurate because I don't want to complain to the seller if there is nothing actually wrong.
Thanks

How to gets off write protected the USB with h2testw and now USB is going write protected and can't working. And it can't formatting any one software and other format tools.

Can anyone tell me what this means? I had bought a 512 sd card and tested it on h2testw but do not understand the results, can any of you help me?​Please put this in the simplest terms possible as I'm not very smart lmao

64GB MicrSD card shows up at 1.99TB

I put an image on my 64Gb SD card and it went great, when I tried to reformat it with SDFormatter but my PC flipped and it didn't work.
So now whenever I put in my SD card in my PC, Phone or Tablet I see a 1.99Tb partition. I can't delete it and I can't reformat it with windows.
Is there a tool or a program with which I can restore my SD card original 64Gb size?

This is how I removed unallocated space on my machine:
