which Nokia flip phones will reformat mSD? - Focus General

My wife has a Nokia 6085 flip phone. I tried my microSD in it. Unfortunetly it will not unformat the card. Any advice on using this phone to reformat the card?
I have a 8GB Kingston C4 which I need to reformat. If I can ever find a way to realiably reformat these cards after having been locked to WP7, then I'll remove my Patriot 16GB C4, reformat it, and run it for numbers. But not going to remove a known working card when I do not have a way to reformat it. BTW, the Patriot is currently at: Total 22.12 GB;;; Available 10.25 GB. I'm going to keep loading it up until only 2 GB remain. So far have had no problems.

You're gonna need one that runs Symbian, as it's Symbian and not just Nokia that supports the secure digital standard. The N75 that I have that will notice a WP7 card is running S60, so you don't need an N8 running full-blown symbian^3, but you may at least need S60. You can check over at pdadb.net and search by OS to see a list of everything that has ever run Symbian. Best of luck!

Mini Sd card not recognized in my wizard

hi guys your forum is great cant stop reading.But i have an issue i recently bought an 4gb mini sd card for my phone the card works but is like it works when it feels like if i put it in and wait for a while or just randomly turn the phone off and on it will work i format it using my card reader through windows on fat32 and all the thing is it works but i should not have to be going through all of this for the sd card to work.
My next problem is i recently upgraded to SNN Edition Version 3.0 LITE and i have to say i love it but before my phone could detect my sd card and from i did i upgrade its not detecting my card at all to be on the safe side i took out the card before the upgrade and now its not detceting at all please can any one help me is there a patch i can use or something HELP!!
i think try to format via fat16 option. i had earlier 2gb kingston card sdmini after formatting it works welll
i was doing some reading and i was told that 2gb is the highest for formating with fat16 i have a 4gb card so this cant work for me a even look in properties and the only option is fat32.any body else as any more in puts.
4GB cards are almost exclusively multilayer, and cannot be read by the Wizard's card reader. You are basically limited to 2GB, and it should be formatted as FAT, not FAT32, as was already noted. If there's a 4GB model that's single layer, that's great, but I don't know about it. (...not saying I'm the definitive authority, either...)
which program can i use in windows to format the card in FAT and not FAT32 and as i said before the phone could read the card before i did the upgrade the only thing its takes a while for the phone too detect the SD card and thats in FAT32 format but i will try the FAT format.
from my experience you can't put ANY 4gb minisd card into the wizard and have it work correctly since it uses double buffering which the wizard doesn't support.
you have 2 options.. either buy a 2gb one.. or format only half of the card in FAT ...as myrddin said.. this might use only 1 buffer..
if that doesn't work, you can look for a program which blocks clusters and block half of the clusters on the card. that would certainly work but you won't be able to get 4gb out of that card ever again.
i'd go with the first option.. 2gb cards aren't that expensive nowadays.
well guys i bought the sd card for my phone and i research before buying it and it caused work so there must be a way for this to work even if i have to split it in 2 partitions but i am at work now so when i get home i will work on it (good thing i bought that card reader) lol but i will give you guys an update soon i plan to format the card in fat16 all 4gb if that dont work i am going to split the partition in 2 but i would love a single partition but what ever works.
I have a 2gb SD Card...
Hey guys... i have a 2gb kingston card (micro SD with adaptor to miniSD), but i have the exact same problem... my wizard just stopped reading the card! Sometimes it reads, but suddenly wizard stops, i have to make a soft reset and.... the card is gone... i formated it to fat32 and fat... and it still doesn't work... any idea? thanks

Correct-o-mundo.
Another common problem (related more to card readers than just to Wizards) is that the reader contacts (and even the card contacts) can become worn, dirty, or corroded. Try removing the card and battery, and get in there with a VERY bright light, a magnifying glass, and some cotton swabs dipped in isopropyl. Clean the metal contacts on both card and Wizard. Be careful not to soak the chip. Damp, not wet. Soak the chip and you WILL be buying a new one soon.
Let things dry COMPLETELY before trying anything, or you'll be sorry.

Problem with micro sdhc

Hi guys! I recently purchased HTC Touch Pro and A-data 8 Gb micro sdhc class 6. My laptop recognizes the card and I format it to FAT 32, so I think the card functions properly. The problem is that the device does not recognize tha card. I updated the ROM with the latest official release from the HTC site , and I was happy finally to see my card. The problem is that after restart, the card is invisible again. Can anyone help me? Maybe the storage card is faulty after all?
Possibly man, i am sure you have another card in there. Test it, if all is ok with it, then exchange your 8GB if possible....
The same thing happened to me; I don't know if it's faulty though. It is recognized at first, and of course I can transfer files from my laptop.

incompatability with SDHC
There is a known partition problem that can destroy your Micro SD (or any other size SD) if you every stuck it into an older reader that does not support newer sizes (any HC, or even standard SDs over 1GB).
Old readers can show your newer SD-family cards, and APEAR to work, until you fill them up past the size the old reader supports.
FOR EXAMPLE:
my old laptop has a built-in SD reader. Back when I used the HTC Wizard, I bought a 2GB miniSD, and dumped files to it from my laptop. Little did I know, the built-in reader only supports SD card up to 1GB. It worked back and forth many times untilI crossed the 1GB line (filled teh SD past 1GB). Then files disapeared or could not be accessed randomly. Kindgston told me it was a known issue of some older devices (readrer/camera/etc): the older device messes up the partition, which you CANNOT fix yourself: reformatting the messed0up partition does nothing. Ship back to manufacturer to fix. Now I'm careful to avoid the built-in SD reader
So I would advise: fill your microSD up aver half-way, and see if you desktop/ laptop has problems accessing files sampled from all over the chip. If it does, this is probabaly your problem.
I think it's just the card/brand itself. The HTC site lists card brands and sizes that have been tested and proven compatible, and the A-Data 8GB isn't one of them (although the 4GB SDHC is compatible). Sandisk is the only 8GB card that's supposedly compatible, and I've pretty much found that out since I had no luck with an A-Data 8GB but the Sandisk works flawlessly.
When I first copied files over to the A-Data and put it in the phone it didn't recognize it at first, but after a couple times of taking it out and putting it back in I was able to read and write to it in TotalCommander, but when I went to play music files the player froze up solid and the card was no longer readable until I did the in and out thing again. Bottom line was there was no way that card was going to work right in the phone, but as soon as I started using a Sandisk I never had a problem.

my touch pro two times had the same problem.The sandisk 8gb microsd HC (class2)collapsed.I can do nothing.My computer doesnt recognize the card.I cannot format it also.Does anybody can help me .What can i do.Thanks.
Card doesn't work in my Fuze. Oh well, I'll find another use for it.
Wierd.... I have two Adata 8GB cards, one works in the Touch Pro, the other doesn't. Both of them work in my Sharp EM One.
hi ive been looking like crazy to fix this problem but this seems to be the only post close to it.
i recently got a transcend class 6 4gb micro sdhc (listed on the website as compatible) for my htc fuze. the fuze (WM6.1) has been updated to the new rom version (5.xx).
i put it in nothing happens. it work fine on a computer (via usb reader). i have a kingston 2gb micro sd that works fine (but is used for another device). I really want to get this one to work so its not a waste.
so far ive tried reformatting to FAT, 64K and FAT32, 32K (via windows vista formatting).. none of which work.
really annoying, i dont have any other device that uses this card and i specifically checked this brand and type with the htc fuze and seems like everyone having no probs with it.
any other things i can try? is it a faulty card maybe (but it works through usb reader)?
I am having problems with the 8gb class6 cards as well. I have tried the Adata and the transcend cards. Here are some interesting things I have found.
1. The energyrom series of roms seems to be the only rom that lets me see the card.
2. I can't access the card until it the rom loads.
3. I can flash roms from the card even if I cant access them from the phone.
I did see there was a utility to help load SDHC cards called SDHC_WM6. I was never able to get it to load right but it indicates there is some kind of software driver that might help these cards.

I saw this utility too.. but its for windows mobile 6 not 6.1.. when 6 came out it had no support for sdhc so that thing came out, 6.1 should have support from the start
of course that didnt stop me from trying it anyway... doesnt work
I have a 8 gb Sandisk- Works flawlessly. I have a 16gb Adata( class 6) that worked for awhile then stopped. Put the 8gb- works, 16gb doesnt. tried different ROM- Still same effect. I has to be the Adata card. I am going to try a 16 gb Sandisk when my funds are available.
Oh- the 16 works fine in the microsd/SD card reader......
SDHC Class 6 works in HTC Jade
I have a jade and both cards that refuse to work with my fuze work just fine with the htc jade. I am not sure if it is a hardware problem or an issue with some software such as the sdhc.dll.
My thought is it is probably software. Why?
First the class 4 cards work just fine. In fact I am currently using a Dane-elec 16gb class4 card.
Secondly I am able to get intermittent class 6 cards access if I use one of the NRGY roms.
I have been using a 8gb Adata card that I bought from newegg, and it has been working flaslessly since november.
I recenlty bought another 8gb Adata from meritline, and this one does not get recognized by the fuze.
I then read in the above posts that somebody used Total Commander to copy files, so I opened up Total Commander, and the card is shown there.
I closed the the program, and now the File Explorer can see the card as well.
Maybe you can try the above steps and see if it works.
edit: actually, I have to plug in and out a few times for the phone to see the card...
I also have this issue with my transcend 8GB class 6 microSD.
HTC Touch Pro (T-Mobile), upgraded to EnergyRom. After upgrade, able to work perfectly. After few hours (the phone of course went into sleeping mode), then the phone was not able to read the card, so starting application installed in it makes the phone hangs.
After a while, the application (10-15 mins) was able to start, then everything is normal again. Very confusing.
At the moment I am assuming it's due to the sleeping mode, somehow the phone (software??) was not able to 'resume' reading from the micro SD.
Note: Previously somehow it clashed with the keyboard mapper software (pro_fuze_keyboard.ZIP), then I uninstalled it, then it was fine. Then I install another version of keyboard mapper (Shlomki TouchPro Keyboard in Fuze ROM.cab), then it's fine again, so I now stick with this mapper. However above issue is still happening.
I read some thread about changing some registry (pnp** set to 8196), so I set it. However still the problem persists.
I haven't tried other suggestion to tweak other registry values. Here's the thread on Hermes device: http://forum.xda-developers.com/showthread.php?t=294324&page=29
I am wondering if it's really class 6 problem. Is there anybody having the same issue with 8GB class 4?
Note: my PC can read the card without any kind of problem.
I put the microSD into N95 also without any problem.
and i have the same problem to touch pro will not recognize my sdhc 4GB class 6, and i have no problems with 4GB class 4.
HI Bobby,
Were you able to get the Transcend 8gb Class 6 work on the HTC Fuze? I have the same problem. I upgraded the rom from the HTC site and I could see it. But later I plugged the card using the adapter to the laptop to copy some files and when I plug that back into the phone, it says "Not Installed". My happiness of not losing 20 buck was only for a couple of mins Any help is appriciated?
Can you give me download link for the energy rom which actually worked with the card?

I had somewhat of a similar issue, wondering if anyone else has seen this?
8 Gig no name brand MicroSD card in my TouchPro, all of a sudden I had less than 1 gig left, using Resco I couldn't see a thing taking up all that space but it was all gone.
I put the card in the transflash adapter and looked at it on my desktop Windows Explorer and saw the following folders in \Storage Card\Program Files
one directory named (*#LD*))#KDP|} with some text after it
another directory named (#*(Y%*(#(*#*(@#kKD* with some text after it.
NEITHER directory could be renamed, moved, deleted, or anything.
Formatting the card hung the format process.
Finally, I put the microSD card back in my TP and all of a sudden Resco Explorer saw these directories and so I just deleted the Storage Card\Program Files directory (no programs in it) and formatted the card and everything was fine.
Anyone else ever seen this?

[Q] List of Symbian phone in the US (SD card format)

Does anyone know of a Nokia/Symbian phone available in the US to unlock WP7 formatted cards? I went to T-Mobile yesterday and they didn't have any Nokias on display. I would like to have my card usable again.
the nokia N8 or any symbian phone running the same version os, you cannot unlock the card, just format. I brough my microsd alive yesterday using the N8, i dont have the phone, but i have many friends who works as promotors for nokia, samsung, LG etc. so i tried the N8 yesterday.
the instructions.
you can put the microsd hotswap or have the phone turned off,
the phone will detect the microsd, and ask for a passwork/id (after it's been in a windows phone, the microsd will be locked, and as normal you wont have the password/id).
press cancel.
in the main menu, goto applications, and select office, file mgr.
after you press file mgr., you will have 3 drives to choose from, the last one should be the microsd, and it should'nt show any figures of the size of the usage.
press and hold, you will have 2 options to choose from.
unlock microsd and format.
select format.
that it.

i think symbian ^3 only, you can try them on others, it may work, but have'nt tried it.
I doubt a regular Nokia phone will work. I tried a Nokia flip phone & it asks for a password, but when you cancel it didn't let me format the card. I went through every menu option without luck.
N8 and C5 works, tried them myself, c6 and C7 should also work, or the latest touch screen in the C series.
The Sony Vivaz will also format. And BTW... I put my microsd card into laptop (using adapter) and after multiple tries it did actually format !

How did you get your laptop to even see the card? My PC won't even acknowledge that I've but the card in the slot, much less offer to reformat.
I have a perfectly good 16gb Sandisk that is useless since I exchanged my Focus for a Captivate on Newyears Eve.
Any info appreciated.
I did it on my HP Laptop with Vista OS. Could it be that I lucked out ? It was a Sandisk 32GB MicroSD card (no class type printed on card). I have also heard that many digital cameras can format them so try that as well. And even worst case try this puppy...
http://www.sdcard.org/consumers/formatter_3/
sd formatter does not work.
Well... it was only a shot at it. And only a guess, but Android phones have a nice utility built in to format micro sd cards as well.
Put the card into Android based phone (2.2 version), then Settings>SD card and phone storage>Format SD card
May work, may not but there are many alternatives to get the card to format. Just keep trying. Like I said, I was lucky enough that my laptop did format after having the card in my Samsung Focus.
Edit: Also note that XP and Vista have some issues. Read article 40, 41, 42 from this list ... http://en.wikipedia.org/wiki/Secure_Digital#cite_note-39
You could also try a laptop or computer running Windows 7.

64GB microSDXC card in a Kaiser

Yes, honestly, you absolutely can run a 64GB microSDXC in a Kaiser. At least I can verify that with WM6.5. I'm using the 64GB card in my HD2 with no problems. I figured it should work in a Kaiser too, so I tried it in my wife's Tilt. I installed my SanDisk 64GB class 10 micro SDXC card in my wife's Tilt and it worked flawlessly. The phone does read the full 64GB and can access it all (less the usual overhead). You do have to reformat it first as it comes formatted exFAT, which can't be read (someone on the HD2 forum has said WP7 can handle exFAT, but I don't run WP on anything so I can't say). It needs to be formatted in FAT32 for WM. The kicker with that, if you try to format it in your PC, is that MS has deemed that FAT32 is 32 GB max (hence the name FAT32, duh) and if you use the inbuilt format feature in any recent version of Windows, it will only format it in exFAT or NTFS. I also tried using a program called SDFormatter but it would not allow me to format in FAT32 either. There is a way to do it from a DOS command but... I ended up using EaseUS Partion Master Home Edition, which is a free program. It worked a charm, and was very fast as well, Then I xxcopy'ed my SD card contents onto the new 64GB card and installed it in the phone. Both my 32GB and my 64GB are class 10s. I use XXcopy to keep a backup of my SD card on my computer, just in case. I update the backup every couple weeks or if I have updated anything on the phone significantly. My wife's Tilt is running ahmedfikry's wm6.5 light rom. When the 128GB microSDXC comes out (and who knows when that will be), it should work in the Kaiser as well. Bottom line is that once reformatted, any micro SDXC card should work in any device designed for microSDHC, regardless of the crad's capacity. So we may someday be running 2TB cards in these old phones. Yeeehaw! Of course you're still stuck with the limits of FAT32, but having extra storage will be nice. BTW I got my 64GB microSDXC card from Buy.com for <$48 including shipping so it's not like these are really all that spendy anymore. For anyone like me who uses their phone as an mp3 player, this is a real plus. Even back when I was using a Tilt, I had my 32 GB card pretty well maxed out with all my mp3 files.

[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

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

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...
