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.

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...).

Not 16gb, but a heckuva deal for a speedy card.
No idea how long this deal is good for, but I just picked up 3 of 'em...

Very good deal, just picked it up hmhm

Ordered this on Jan 4th for 16.99 shipped, it's a good card just got it today highly recommend it especially at that price.

I just bought one for 14.99 w/shipping from newegg.
Someone said that this card was not being read by the Proven 1.10 can anyone confirm this.
Also I am replacing my current Adata 8gig cl 6 for the mere reason that my device does not recognize it in bootloader mode. I hate to flash from activesync. You all can flash roms and radios through this sd card right? No problems?

Just got my in yesterday... so far so good...

Picked one of these up a week or so a go and it works great!

I did some searching is there any other way to format the memory card to FAT32 other than with a card reader? One more question is this memory card already formatted FAT32?

it doesn't matter. reformat the card. YOU SHOULD ALWAYS REFORMAT THE CARD.
Factory formatting is always screwy. And I'm pretty sure there is an app to format a memory card on winmo...but I'm not sure.
But yea this card is FANTASTIC!!!!!!!!!

yeah I dont have a card reader.. so thats why im asking about any programs out there..

Anyone hear of any SDHC cards not working on the Raph? I have a camera that likes some SDHC but not others. It's not so much by brand as by model. Just curious if it was just me or are there others?

To format your card plug your device to your PC as a "Disk Drive" and format your card via My Computer.
Voila.

Just jumped on this deal. Thanks.

Got mine today. Making separate cards for my Android work for the Kaiser and Raphael, plus another with just media on it. They seem to transfer a lot faster than my class 2 cards.

Umm sorry but how do you plug you device so that the PC can read it as a "Disk Drive"?

When I plug my data cable in it automatically gives me the option to
Auto Sync
Disk Drive
Internet Sharing
choose Disk Drive if applicable, should allow you to see it in My Computer on your desktop now as a physical disk drive.

Hmmm yeah thats what I was curious about I looked on My Computer but it doesn't show it as a physical drive... any settings that I need to change?

Interesting, nope I don't think I had to do anything special. Does your cell phone read the card fine?

help with cabs on new sd card

Just received a 32Gb sd card and copied over all my files and cabs etc.
But when trying to reinstall the .cabs to my storage card and keep getting this message "installation of .cab was unsuccessful" ?????
has anyone got any ideas? I have had to go back to my sd card?

didn't think there was any decent 32gig cards available yet, did you format the card in your phone first?

The correct procedure (which I did only last evening with my new Sandisk 32GB mSD, it will take approx. 2hrs. depending on capacity and content of old mSD - mine had full 15,5GB):
1. Put back old SD-card
2. Switch HD 2 into flight mode (!!!!)
3. Connect to PC in HARDDISK Mode (not ActiveSync)
4. Open mSD card on PC and make ALL files accessible (also system-files etc.)
5. Copy entire content of old mSD to a fgolder on the PC
6. Disconnect HD2 from PC
7. Switch HD2 off and place new 32GB mSD into HD2
8. Switch HD2 ON
9. Check if mSD is recognized and shows right capacity (29-31 GB depending)
(EDIT: 10. Format mSD with format-prog in Settings-menu. HD2 STILL IN FLIGHT MODE !!!!!!!!!!!!!!!!!!!!!!! (EDIT!!!: MAYBE BY FORMATTING YOU COULD GOOF THE CARD, SO BEST IS TO USE IT AS IT IS RIGHT OUT OF THE BOX !!!! AND TRY TO FORMAT IT ONLY IN CASE IT DOES NOT WORK PROPERLY OUT OF THE BOX !!!!!!!!!)
11. Connect HD2 again in Harddisk-Mode to PC
12. Copy all files from backup-folder of PC to the new mSD
13. Disconnect HD2 from PC
14. Switch HD2 OFF
15. Restart and enjoy Your new richdom of mem-space
DO NOT ACTIVATE ANY RADIO (GSM, 3G, HSDPA, WIFI DURING ENTIRE PROCEDURE !!!!!!! It might brick Your new expensive mSD-card cause WM once in while writes to it creating funny disorders on the new card.)
After restarting with new mSD there might be a "services.exe"-error. Switch off again and switch on again. No error-message any more.
I strongly recommend to invest 24 bucks for pocket mechanic or SKTools (I prefer PM but have both running). It helps You to optimize Your entire HD2 and evaporate all crap accumulated when playing around with install and del of mods and apps. Makes WM pretty stable and snappy

troed thank you, but i am still having problems????
i have a games folder with cabs in and when i copy them over they dont even show and a few other folders have become like encryted??? cant open them or delete them ??? maybe the card is faulty????

Most problems with uSD cards seem to be caused by low capacity fakes being sold as high capacity branded cards.
I'd suggest checking it with h2testw - or alternatively if your new 32GB uSD card isn't a sandisk card bought from a reputable retailer for a lot of money, you don't need to test it to know that it's fake.

Well, andyfoster could be right .....
I always buy my SD and mSD cards (only Sandisk) either at amazon, expansys or mobilefun and never ever had a single problem with them (e.g. I also run 32GB SD and MemStick in my Vaio).
Once I bought a Pretec 128GB SSD Express Card for the Vaio, filled it with read only files ...... worked ........... but when I wanted to check the content the SSD was dead/bricked.
What else could it be theoretically ?
Once I bought a Kingston DataTraveler-USB-Stick 64 GB and wanted to fill it with vid-files. In copy process it got stuck so I formatted it and now I have only 32GB available.
Why ?
As delivered the 64GBstick was formatted FAT 32, allowing only files less than 4GB saved onto it. This my fault then. One vid-files was 6 GB and gave an error. But when I destroyed the original format from Kingston with my formatting I lost half of the capacity with no workaround left.
What do I wann say with this ?
I don´t know if THAT could be the case, but MAYBE these high cap-SDs do have a special "Factory-format" that should not be changed ! When I received my 32GB mSD IT WORKED PERFECT OUT OF THE BOX ! I did no format. But, honestly, since it is a lill bit expensive I don´t wanna experiment with formatting it now.
But MAYBE it is a fake-card ..................

Yes, the first thing to know is how much you paid for the card and what brand it is... we've seen "ORIGINAL KINGSTON 32GB MICROSD CARD NO FAKE!!!1!ONE" on ebay, when Kingston never manufactured a single 32GB card yet...

This is a sandisk by the way, (well it says sandisk on it ) and its funny you mentioned the format? it is formated wth the name fat32 hhmmmm and i am trying to put 13gb of stuff on it???, I have reformatted it again last night it took hours?? I might try again and if not i will just have to have a replacement?
after trying again, i notice this error regarding certain file names are to long??? and also if i create a folder and name it vids or movies it automaticly puts folders in side which cannot be opened or deleted? and the folders name will be ".?:-~~{"
its got to be the card right?

I have returned the card and asked for a replacement?

what follows is unrelated to the main topic in this thread...
about the bold part in your post above...i thought i should tell you that there IS a workaround!
fact is that FAT32 is a file system in which a single file cannot be larger than 4GB. you should have gotten an error from explorer BEFORE even a single byte of the 6GB file was written.
more importantly, you should know that FAT32 fully supports very large partitions like 100GB, etc (at the cost of slower performance and/or wastage due to large cluster size at that capacity). what most people conclude is that it SEEMS like you can only create up to 32GB FAT32 partitions "at home" while larger sized FAT32 partitions can only be "created in a factory format". this misconception is entirely because the disk management in windows 2000, XP, Vista, and 7 enforce this limit when formatting!
google it and you will see that it is just an arbitrary limit by microsoft and these same operating systems have NO PROBLEMS reading/writing FAT32 partitions greater than 32GB. once again, it is JUST an arbitrary limitation of the default formatting routines shipped with windows. there is a great little tool (i forget the name of the program but its executable is called "guiformat.exe") that will allow you to format FAT32 greater than 32GB.
all of the above got me thinking about something though...it seems that manufacturers have chosen FAT32 as the de facto standard for most mobile devices with removable card storage (like smartphones, digital cameras, mp3 players, etc), likely because of FAT32's lack of complexities like security and the standard's relative "openness" compared to that of NTFS, for example. makes me wonder about the nice surprise people will start to have once greater than 32GB cards become available and when people will attempt to format them with windows, expecting everything to go smoothly...but oh the horror when windows won't let them format greater than 32GB. good times ahead!

[Q] Question on Sandisk Ultra Class-10 64GB microSDXC

I have some questions to pose regarding the Sandisk Ultra 64GB Class 10 microSDXC.
I bought it about a month ago, and when i first put it into my Samsung Galaxy S4 GT-I9505, it didn't read anywhere near 64GB. Hence, i formatted the new microSD with Samsung's format option, and it showed 59.48GB. Worked perfectly from there.
However, i find the default file system of the microSD card really slow in transferring files when i connect my phone to the PC via USB, with the microSD mounted on my phone. I have a Kingston microSD reader, so i used it to connect my microSD to the PC, and tried to wipe and format it to FAT32. After doing so, the storage size became like 27GB. Is there a way to make my microSD running FAT32 system and get it to work on both my PC and phone without any problems with the size?
Anyway, i formatted the microSD again with Samsung's format option, and it went back to normal 59.48GB. However, i used my microSD reader to connect it to the PC, and it couldn't read the microSD card. It prompts me to format it. Is it because my microSD reader does not work with microSDHX cards? Or is it because my Windows PC cannot read the microSD's file system?
Hope someone has an answer, thanks.
P.S I posted this as a reply to an old thread, but realised it was in the Galaxy S3 forum, so i figured i'll post it here.

So you could use the memory card in your card reader after formatting the card as FAT32?
What OS are you running on your PC? If it's Windows XP, support for exFAT needs to be added. You can find more on this here: http://support.microsoft.com/kb/955704

use a program such as H2testw to see if your microsd card is fake or defective . You can get it from here or google it .

I found the solution. The Kingston USB reader that i used is actually not compatible with my Sandisk MicroSDXC. That's the reason it couldn't read my microSD when i connected it to the PC. I used the SD card adapter that came with the microSD on a newer laptop which has the port, and it read my card perfectly.
Anyway, i ended up putting my microSD back to my phone and formatting it using the Samsung option. Then, i used a program to format the microSD to FAT32, which i don't think is actually necessary as there wasn't any reading/writing speed difference when it came to transferring files.
Cheers.

Micro SDHC 64GB 10 Series
I wonder if someone can help me.

When I opened the packaging, the card first asked me to format the card fr use. At first, The SDHC card worked fine.
But now when I attempt to use it via laptop, The SDHC card doesn't show up on "My Computer"
It's like the card isn't reading at all..
Any suggestions?

I've been playing with Windows since Android's grandfather was a tadpole, so in a combination of research and personal expertise I present the following advice...
DO NOT install a SD of a Class other than what is listed in our phone's Hardware Compatibility List - they being a Class 10 MicroSD, MicroSDHC and MicroSDXC - beyond that of 32GB, as you're only looking for trouble. Sometimes bigger is not necessarily better - just ask the people who knew the man that ate himself to death. NAND technologies are getting better by the day, but unfortunately devices grow increasingly incompatible with newer variants of MicroSD's simply because of the changes made within the firmware of the NAND controller. By changing Class outside of the scope of our phone's capability, problems can arise. Kind of like having a PC and trying to use a SATA-M drive on it. Unless you've got the physical hardware and device drivers installed, you can't expect it to work properly, same as throwing a SATA3 drive on a SATA2 port and expecting it to transfer data at over 3Gbps. If you find you are so desperate that you just can't do without having a 64GB card installed, go to eBay and grab yourself a Genuine Samsung 64GB 'Evo' Class 10 MicroSDXC. They are the fastest and highest capacity MicroSD our device will be friendly with (due to NAND controller compatibility) and at the moment they're going for good prices. Once you get it, Format the thing on your phone first, according to Samsung's instructions for installing the card. You'll then have a bit less than 60GB of storage space, along with Samsung backup if something does go wrong, simply because you're running a Samsung card in a Samsung phone. Trust me, its a great combination, proven by the fact my Samsung laptop runs like a dream on the Samsung 840Pro series SSD it has in it's belly...

128gb micro sd card problems

Hello All
I bought a 128gb micro sd card for my z3 compact only to find out that i will need to format the card to fat32, which seems to be impossible now, i cant even format mat it to anything now let alone to fat32.
I have tried as many way to do this as possible but i keep getting errors of "format didnt complete" or some variation of that.
I have tried using cmd prompt, GUIFORMAT, windows disk managment and multiple youtuve videos.
I have read that the phone can take this type of card if you can format it to fat32. If someone has achieved this or has any advice, it would be greatly appriciated.
Thanks

Get a refund as soon as possible. You almost definitely received either a dud or a counterfeit. If you do end up being able to format it (any file system will do) run this:
https://www.raymond.cc/blog/download/did/77/
If that reports it's stable, try formatting it as NTFS in Windows. FAT32 can't handle files larger than 4gb, and exFAT isn't compatible with Android, iirc.

you sir are a great man.
i think the card is messed up, i cant even open it in windows, acting if its not even there. Even in the properties i get no deteials, everything is 0. Putting it in my phone even says sd card is damaged.
I keep reading people have these cards in tehir phones and tablets. Are you aware of a way to do this?
im sending this card back and getting either a smaller one or research into how others have managed to do it.

If it is a sdxc card, u tried to Format it via phone? Never had problems with my 64gb card

I have 128GB card too. Just put it in the phone and let it determine the type it wants. After insert the card, open setting - storage - erase SD Card. Then the 128GB should become exFat.

I have a 128gb SanDisk card in my phone atm. I formatted it to exfat on Windows 8.1 and then inserted it into my phone and formatted it again using the phones format sdcard option. (cus I'm thorough like that)
Currently it is listed as being formatted as texfat.

I'm not sure what you're asking here exactly, but when a card works *properly* you can just insert into basically any device and it'll format it in a few different ways, not unlike a usb flash drive.
I've had your exact problem before, though. I bought a 128gb sd card from a seller with a really high rating on Ebay, but it was for $55 and I should've known better. It was almost definately a 32GB or 64GB disk that had been re-partitioned to look like a higher capacity drive. The 'new' disk would destroy any data copied over to it after a certain limit was reached, a limit that got smaller and smaller the longer I held on to it. I'd format it, start copying, the copy would fail, the disk would eject itself, Windows wouldn't recognize it until formatting it, rinse repeat forever. I wasn't even trying to fill it to the brim, 'just' my 55ish GB music collection. I ended up actually finding one for $80 on Amazon, which ended up working flawlessly.
If you don't mind my asking, where did you buy it from? How much did you pay? What was the seller's ranking and review history like?

I have had similar experiences myself with micro sd cards from eBay. It seems to be inconsistent regarding particular sellers and the quality of the cards. I would imagine there are sellers also getting scammed by wholesalers claiming to have legitimate cards.
Needless to say, I only buy micro sd cards now from sellers that are
A) in my home country, where I know they are bound by local law regarding faulty goods
B) selling brand name micro sd cards in their original packaging.
I might not save as much money by playing it safe, but it's worth it to be able to rely on a product and have a local warranty to back it up.

I have a 128gb SanDisk card in my phone atm. I formatted it to exfat on Windows 8.1 and then inserted it into my phone and formatted it again using the phones format sdcard option. (cus I'm thorough like that)
Currently it is listed as being formatted as texfat.

I've had problems with Busybox installed on phone and it corrupting SD cards somehow, "Busybox on rails" was the fix for me, also it seemed to fix the damaged??? SD card after a reformat.

I also experienced similar problems with my 64gb card. It worked flawless in my Phone for some months, but when i put it in a defective card reader and connected it to my NAS, the card seemed dead. My Phone said the card was corrupted and it wasn't able to format it. My Windows PC didn't recognize it at all. Also "sd formatter" which never failed in the past, couldn't get the card back to life.
So I checked the card with fdisk under linux and I could see, that the partition table was totally messed up. I deleted the partition table and after that the card was working again.
No problems in the last 2 months. And since I have a fully automated daily backup to my local NAS, there is no need to exchange the card "just in case".
