Not seeing 2GB Micro SD Cards

Has anyone managed to get hold of one of these yet?
I got mine this morning having found the 1GB I had previously to small.
Its just a basic Sandisk 2.0 GB card same type as my 1GB but my M3100 is not seeing it. It works fine in my pc card reader but the PDA is just not picking it up. :?
Anyone got any ideas?
Its formatted using FAT32 straight out of the box.
Any ideas would be great.

I will remember there was a problem with other HTC devices with SD cards larger than 1GB depending on the reading speed.
I'm not entirely sure, memory a bit vague about this, but have a look around.

Have u tried a soft reset after inserting the card? Seems to work most of the time assuming the TyTN isnt faulty. I use a Sandisk 2GB myself with no problems.

Same here.

Im using Sandisk 2gb and all working fine too..

Same here. No problems with the SanDisk 2GB card

Is the card formatted with FAT32?? afaik standard FAT (aka FAT16) wont address volumes higher than 1.2GB???
Slap the card in your PC and format it with FAT32 instead then give that a shot!?
EDIT:: i stand corrected....FAT16 can (technically) support up to 2GB, but try it anyway!!!

I have the Scandisk MicroSD 2GB as well, however mine is formated is FAT. It came that way and I also checked the existing 1GB I have it was also formated as FAT.
I did one time format my 2GB as FAT32 and it did not seem to perform better so I went back to FAT.
Nonetheless, both FAT and FAT32 seems to work okay for me.

MicroSD format question.

I currently have a 2GB MicroSD card with a GPS program loaded on it. The card was provided to me by the manufacturer. I prefer not to constantly switch the card out to put in a 6GB one that holds music, movies, photos, etc...
I tried to simply copy the contents of the GPS card to my new 6GB one and when I start the program I get a hardwareID error.
I figure it has something to do with the volume serial number or possibly the mbr/disk signature, but not sure. Anyone know of any utilities that can assign the volume number? additionally anyone have any ideas of what the software could be checking against on the hardware?
I'm not in anyway trying to cheat on licensing, it is just purely an inconvenience.

micro sd
I think the max size is 4Gb

I have the 6GB card working fine on the tilt.
Of course anything past 2GB has to be formatted FAT32, so the 2GB is FAT, while the 6GB card is FAT32, but other than that, it works fine for storing music, documents, videos, etc, just not for my GPS program that seems to be locked to that particular 2GB microsd card.

That's the exact reason I won't buy any GPS prog from a vendor that locks it to a particular memory card.

Can a sd card be partitioned ?
If so set up a 2 gig fat 16 and a 4 gig fat 32!
I don't know if it can be done or if it will work.

Don't believe it can be partitioned.

I got 6GB and it works. A friend of my has a 8GB card and it works.
In theory the SDHC system can work till 32GB

With a little trickery they can be partitioned in XP/Vista using diskpart, etc., but they won't be visible to WM5/6 then.
Kinda useless if you want it to work with your Kaiser

It could be a bad flash card (either one). Try copying folders one at a time from the 2GB to the 6GB card, instead of all at once. Do the file transfer on a desktop PC, as WM6 might choke when doing large file transfers between FAT and FAT32 (not that its a known bug, but hey, its Windows...).

formatting for android

ok so apparently its best to format to FAT32 32cluster right? but is FAT32 the same as just FAT 32cluster size or not? having problems achieving both
you cant choose these options through sd format on the phone and if i try to do it through my pc via usb Disk Drive connection, on windows format i can choose either -
file system: FAT (default)
Allocation unit size: 32 kilobytes
OR
file system: FAT32
allocation size:lots of options but not 32!
also tried a pc card formatter i saw in another post but that doesnt give many options and when its formatted it says its just to 32
card is a sandisk 2 gig not sure of the class? just came with the phone

maybe a 2gig micro sd doesnt support 32k clusters in fat32?
try upgrading to a 4 or 8 gb card. maybe even a class 4 or 6

yeah maybe. might have to invest in one. surely that would then make android more reliable also???

I've read and found through my experience that my Roms run best with a 4096 cluster size. Any time I tried another size I would get stuck in the crazy fsck check with a large amount of those files all over my card. Though I have also been told that bigger is better.
Basically all my sd cards have been formatted like this.
format x: /fs:FAT32 /a:4096 /v:android /q
x - being whatever drive you have assigned to your phone
android - being whatever label you wish
Never a problem since.

I use 64 cluster size formatted using pc and it works great for me. Supposedly it gives you less space but faster r/w speed. I've never had an issue with space using stock 16 gig class 2 card and runs every build I've flashed great.

64gb card =2tb

So I have a 64gb sandisc u1 card, in partition magic it shows the usable space as a partition in between a small set of unpartitioned space and a large set.
All space = 2tb
Thoughts?
Explinations?
Exploits?

You tried to download file biger than 64 gb on this card?

I didnt mod it yet. Its from bestbuy and leget in size reporting 59gb currently. I do not buy flash memory off ebay. I do not reformat flash drives in ways that I am uneduacted about [increasing size that is, im well versed in partition magic]
I know my 16gb class 4 kingston never did anything like that, it showed leget always.

Where is a file larger than 64gb? Not even a 3d high def video lol

Well you can always download several large files and see till where u can copy

What file system is being used? Windows doesn't like FAT32 drives over 32GB. It will R/W to them fine but refuses to format them. 2TB is the maximum size for FAT32 drives IIRC so that is probably where you are getting that number from. I own a 64GB microSD and my advice would be to format it in an Android phone and once done it should report something like 59GB space available.

It dose this on fat 32, exfat, or ntsf
Partition magic dose not equate windows formaring tool

I'm getting a similar problem,
I need to format my SD card with 2 partitions for my phone, for a link2sd app
but my 64gb Micro SD is showing as 27gb when i put it in my computer

I thought Fat32 supported up to 4TB?

It might. I know for a fact it will do 2tb I have a 4tb drive half ntsf half fat32

Have you tried looking at it with another partition editor? Does your hardware that you are using to read the card support SDXC properly? I highly doubt that it has more than the advertised 64GB of space, considering what a loss that would be for them to manufacture.

Fixed for Samsung 32gb class 10 uhs-i
My new Samsung 32gb Plus class 10 uhs-i also showed up as a 2TB drive with a 32gb fat32 partition in partition magic I even upgraded to the latest version of PM but it still showed as 2tb
I fixed it by swapping the usb adapter I was using :victory: now shows as a 32gb drive in PM It would have been nice to have a 2tb card though :laugh: If you are using a card adapter this also may cause errors if the card reader in the pc is old or has out of date firmware mine just plain refused to read it so hardware problem rather than software
Hope this helped :good:

If you bought the 64GB card and it showed as 2TB on computer display, 99.99% was the computer-end problem such software reading incorrectly.

Dude it was 150% certain the USB Card reader & not the software I speak from actual experience & not something I found on Google.
Some older or cheap card readers do not display the correct values back to the software. The built in drivers of some USB card readers cannot accommodate these new type's & size of card. Exactly the same issue can exist with the built in pc & laptop card readers that's why you may have to make sure the driver is up to date if the size reads strangely :good:

Firstly, what I meant was it is NOT the uSD itself that causing the problem or the confusion.
Secondly, FYI, "The built in drivers of some USB card readers" is a piece of software. I hope you understand what the driver is

Check if the partition table is a MSDOS one.. And upgrade your drivers..
I love windows for that.. it found a flash drive size of -2147483647... No, this flash drive didn't destroy 2GB of my hard drive x)

Formatting error...
This has happened before.
There was a chinese website where you could buy 2TB USB Sticks, but they were just 8GB sticks re-formatted to 2TB and they didnt function as 2TB.
I believe something like this may have happened.
You need to run tests for this, try seeing how much space there is using different programs that expore it.
If possible, try and accumulate files that are over 64GB in space, some movies/games/torrents etc. and copy them to the card.
If it's more, then lucky you
Peace,

I give up
Advice rejected by people who all know better than I.
Waste your time by all means & mess with the software of your pc. Overload the sdcard and screw it permanently :crying:
Maybe you could just try a different USB card reader simplz :laugh:

You probably need to format the other partition

[Q] Vaio duo 11 compatible with UHS-1 64gb micro SD cards?

Hi I need more space for my duo 11 and the cheapest way i believe is to buy a micro sd card to increase the size(Don't know if i can swap my hard drive from 128gb to 256gb). I spotted this micro sd card which is pretty good but don't know if i can utilise it to its maximum speed. The card is "Samsung UHS-1 Class10 PRO Micro SD XC 64GB Memory Card", I know duo 11 supports SD XC but it also needs to support UHS-1 for it to use it up to its maximum speed.
On a side note it says
-Read Speed: Up to 70MB/s
-Write Speed: Up to 20MB/s
Does take mean if i transfer files out of the sd card it can go up to 70mb/s and if i want to transfer files from my hard drive to the sd card the transfer speed would be 20mb/s??
Thanks in advance!

That would be the correct speeds assuming all is perfect and no overhead.
You also need to verify that the reader in the Sony is not connected through USB 2.0 or you wouldn't see 70MB/sec reads, more along the lines of 30-35MB/sec.

The duo uses sd cards not microsd. You can use a microsd card with an adapter but a sd card will be cheaper.
I have a 256gb sd card in mine and it works but it's not particularly fast.

That would be the limiting factor as far as the SD card is concerned yes. Operating system overhead would slightly reduce that. Also there would be a limiting factor in what the hard drive read and write speeds are or memory stick or whatever it is the files are being transferred to and from.
