Anyone has problems with 2 gig SD card in their 8125?

Everytime i insert my card it asks me if i want to format it to make it readable? - even though i formatted it in my computer. Also i cant write anything to it when my 8125 recognizes it in a slot. The cars is SanDisk so it should be a good quality.

I'm using a 2GB SanDisk card with no trouble at all. I _didn't_ format it on my PC but rather used it straight out of the box.
Do you still have the same message if you let the 8125 format the card?

i tried doing that and it says that the phone cannot recognize the card.... the weird thing is that the card goes in crooked and the fit isnt perfect i have to push it in hard.....

Quite a few people reporting a problem like this - seems to be fixed with sktools or storage tools (google them demos allow you to format - install on device) and format card on device to fat16.

I have the same problem before, i tried to format it to fat16 and the 2gb minisd was recognized as 1gb instead of 2, tried every solution from getting compatible version of a card reader to re-format using fdisk via DOS., Called the manufacturer and they we're happy to replace it. They advised that it should be re-formatted as fat only and not fat16 via DOS using the card reader.

good to know as i just bought a 2gigger.

The problem is that you formatted it on your PC. USe SKtools to format it on your device and you should be all set. I think the demo version of SKtools allows you to do this stuff.

i use my 2 GIG since i bought the phone almost 4 months ago without any hassle.
Just used the card out of the box without formatting it.

This issue is reported several times and is caused by using a not compatible cardreader on the PC to format the card.
A lot of the (even usb 2.0!!) cardreaders is not capable of reading over 512MB memory cards. If you use a 1Gb or 2GB card on such a reader it will probably say the card is not formatted. WHEN you do format the card using that reader, you wil make it unusable.
:arrow: Make sure you format the card via a compatible cardreader to avoid this.
:arrow: If you get a 'card not formatted' message, try to read from / write to it in your device first (before attempting to format)

Just got my 2GB card....MDA won't read it.
Camera won't read it.
PC can read it. It was Fat32, I reformatted it to Fat...still a no go in the phone or camera, but works on the PC....what gives?

I have a SanDisk 2Gig card. It worked fine right out of the package. Haven't had any problems with any of the ROMs I've run on my 8125.

my 2GB card works fine, except for the fact that it's stuck in there.. i need to tak it apart and fix the spring loaded latch somewhere in there..

I got a 2GB from Amazon: OEM 2GB MINISD Mini Secure Digital (SD) Card but it did not work on my Cing 8125.

TopRam
I have been using a 2GB miniSD made by TopRam. Works in the 8125 and with my USB card reader no problem since day one. 8125 recognizes the entire 2 gigs (well minus just a few bits...about 99% of the card). Got it off eBay while I was waiting for the phone in the mail. Never needed formatting or anything..worked straight from the package. I was a little worried at first that it wasn't one of the "well known" brands of cards, but there have been no problems whatsoever.

I'm using the Transcend 2Gb 80x MiniSD. Works like a charm.
Keep in mind that SLC flash chips (mainly made by Samsung and a.o. used by Transcend and Mobymemory) have longer lifetime, are faster and consume less power than MLC flash chips. Disadvantage is that SLC is more expensive. Bought my 2GB for approx 62 euros.

Storage Card Woes(A Public Service Announcement)

People have been reporting problems with corruption and losing files on memory cards, particularly 2GB ones.
I am having the same problem with a PQI 2GB bought from Fry's(PLU# 5044075 and P/N: AE62-2030R01F4) in Houston, TX.
When I try to download something from an FTP Client to the storage card, it fails and when I leave stuff on it, it becomes corrupt and stuff disappears. Also, when transferring files over FTP, it moves at about 5-8 KBps.
I took my roommate's 64MB PQI from his Sidekick III and it worked like a charm. It was as follows.
1 Head
1 Cylinder
Type: FAT12
Sector: 512 Bytes
Cluster Size: 16 KB
BackupFAT: Yes
I used Pocket Mechanic(amazing interface) and Resco which is great and clean as well! Thank you for the recommendation. I scanned my card for bad sectors and they were all good.
This morning I used my co-workers SanDisk 1GB card and downloaded files from my FTP at 22KBps over EDGE which blew my mind. Furthermore, they weren't corrupted. His file system was FAT32.
My conclusion is that it isn't the formatting options, but the PQI cards and the old motto of "You get what you pay for". I am going to have to break down and buy another card which I really didn't want to do, but it's obvious that SanDisk clearly holds it's weight in these devices.
Thanks to everyone who made recommendations and turned me on to some great apps in the process. I'll update this when I get my new card and let you guys know how it went. Thanks again for being a great community!

Flash memory doesn't have heads or cylinders

I know, but the stat was there so I included it in case someone got a different value reported back to them...

Correct, but there may still be logical heads and cylinders for backwords compatibility with some OSes or software.
I dont know about the case with SD cards, but CF cards can be directly connected to an IDE bus and emulate an HD.

MMC Plus and SD 4Gb - slow write speed

Here is a problem... I've tested 4Gb SD card's FAT16 write speed using XDA IIi. And it is 2 times slower than one on 2Gb SD card(both Transcend, 150x). Nearly 630kb/s(2Gb) and 375kb/s(4Gb).
So, speed is unacceptable.
Will 4Gb MMC solve this speed problem?

Hi
You need to reformat you SD4Gb in Fat32. I had same problem like you with MMC+ 4Go and SD 4Go 150x, both from transcend. I reformated in FAT32 and they are more quicker.
Try it and ket me know.
You can use Pocket Mechanic from Anton Tomov which is a very good software.
Cheers

Hmm... Same benchmark gives me even slower result with FAT32... What cluster size are you using?
Best results achived with FAT16 64Kb cluster... Using SKTools for benchmarking.

Sectors per cluster:64
Bytes per sector: 512
Cluster Size is 64x512 = 32768
Hope it helps

MicroSDHC card with corrupted filesystem?

Got A-Data 4gb card yesterday and it worked initially until it started to look strange when I was transferring big files unto it. Seems like I couldn't end the transfer and on it appeared a catalog named xxxxxxx.xxx. I disconneced tilt during this transfer and neither tilt no Dell 1420 with SDHC reader can see this card anymore. Nothing happens at all when I plug it in. I hoped that reformatting will work but Dell doesn't see card even in disk management tools (Vista). Regular size SDHC card is read by dell just fine.
Card hardware failure or filesystem problem? Thanks!

I have experienced this issue as well with both a 2GB and an 8 GB card. I have noticed the corruption mostly happens when I take the cards out to transfer big files using a USB reader. Do not touch the surfaces of the cards, handle them by the edges to minimize the risk of losing your data.

Thanks, I will remember that but if card is not seen as a drive by PC can I still return it to workable state?

You will likely have to format it with FAT32. Obviously your data will then be toast (but in all fairness it probably already is). If you can't format it then you need to google for memory card data rescue utilities. If none of these suggestions pan out, I would start the warranty procedures with the manufacturer to get it replaced.
Hope this helps!

32gb FAT32 SDcard to 64gb exFAT SDcard Problems

Ok so i've been using the SanDisk Ultra 32GB MicroSDHC Class 10 sdcard in my note 2 and when i filled it up i then went out and bought the SanDisk Ultra 64GB MicroSDXC Class 10 UHS sdcard. I want to transfer everything thats on that 32gb card to my new 64gb and keep going. Obviously, ideally having about 32gb of free space when i put the 64gb card into my phone. I cant seem to get this to work right for some reason.
I took the filled up 32gb card out of my phone put it into the adapter it came with and then put that into the sd card reader thats built into my windows 8 laptop. Copied the entire card to my desktop and it turns out to be 37gb worth of data some how?? The 32gb card is using fat32 and the new 64gb card is using exfat...not sure if that matters in any of this? Then I copied that entire folder to the blank 64gb card and windows is telling me i only have 15gb of free space left on the card. The 64gb card seems to read in windows as only about 60gb btw. Where my extra 4gb? regardless...even 60gb minus the 37gb copied to the card should give me at LEAST 23gb....not 15gb. So not sure whats going on here??
THEN i formatted the 64gb card again using NTFS, added back all the copied files from my 32gb and it said i had about 20gb of space left. I suppose thats better but still not what im looking for and i read that i shouldnt really be using NTFS anyways. So then I tried formatting the card in my phone with TWRP and same thing happened as before, only showing 15gb of free space with the exfat format. I noticed in the windows format utility i can chose an Allocation Unit Size...I had left it at the default...not sure if I should be changing that to one of the larger numbers?
Anyway, I just want to transfer my 32gb card to the new 64 gb card and have about 32gb of free space on there....any help with this would be great, thanks!

It depends on a few things. First is the average size of the files to be stored and retrieved. Also the number of files to be stored and retrieved. A single file may be stored in several segments. The last segment will probably not be full, hence wasted space that cannot be allocated. Smaller segments would result in less wasted space, but more segments per file. Larger segments would yield less segments per file but more waste.
All the segments are tracked by the FAT (file allocation table). This index keeps track of all the segments on your storage device. A smaller allocation unit size (segment) would yield in a larger FAT. This will also slow down your read/write speeds. The reverse is also true.
*It has been awhile since I had studied this stuff so my FAT might be a little randomized.

I'm not sure what you go going on.
Couple of quick comments. Not possible to have more data on the card than it's capable of holding; ie 37GB of data on a 32GB card. You may have some compressed files of something, but the compressed files are still a certain size until uncompressed. So, something may have gotten messed up. It happens.
As for your new card having less than 64GB of data, that is normal and expected. There is always some space lost for file allocation tables and various other stuff needed for devices to connect to the card.
As for the new card, since it blank, best thing to do, format using your phone. It's the best place to do it. It will guarantee it'll be formatted in a way that the phone is guaranteed to read and write. And it doesn't take that long; five minutes at the most in my experience, and usually it's more around two. If your computer can read and see the formatted card, I would than just copy/cut the files over to the phone that way, and not use the card reader that came with it. It does take a lot more time, but other than corrupted files, it's always works.
If fact, I almost never use those card readers. When I get a new card or phone and need to transfer data, I just connect it the computer, transfer files over to the computer that way. Format the phone storage or new microSD card (in the phone), than transfer from the computer to the new phone or microSD. Other than a file here and there, no issues. And of those few files, it usually turns out the file got corrupted because I won't be able to open on the PC, phone, or anywhere else. And the problem files are found when transferring from the phone to the PC. The biggest knock on this method, it can be very time consuming, especially if there are bad files.
Other thoughts, I don't recall Android being a NTFS friendly. I thought it was just FAT or exFAT (I believe this is what it generally uses). FAT32 is the arguably the cross platform friendliest since Windows, OSX, Linus, and so forth and all read and write to it. It does have a 4GB file limitation, which depending on what you're using, can be a big problem, especially with video files. I don't recall exFAT file size limit, but it's more than 4GB.

Thanks so much for the info guys! For whatever weird reason it seems the exta gigs of data that transferred off the sdcard was actually files i had deleted a while back...not sure why they were still on there but my phone was reading them as deleted. Not sure why they would copy back to the computer though when i never even saw them to select.
