1 gb sd card - won't upload beyond 716mb

I've just bought a pqi 1gb sd card but can't upload more than 716 mb of data even though settings on my pda tell me I've got 976 mb to play with and there's 257 mb free. When I try and copy using active sync I can't. It tells me there is insufficient room - yet the display shows there is 257mb free. why? Is the card defective?

Have you tried using a card reader? Activesync seems to be problematic when dealing with large files.

Thanks, but I don't have an sd card reader. It seems to read fine if I delete some of the files and replace them again but then it sticks at 715mb. These are mp3 files so not particularly large. Even if i try and add word or excel files it still won't let me beyond 715mb.

Well.. actually my PQI SD 1Gb card is loaded with 875Mb and i have more or less 99Mb free. I used activesync to copy the files on the PDA, so i think that your problem is not on the activesync connection. I have an i-mate PDA2K, and with activesync 3.71 and PQI SD 1Gb card i don't have the problem that you found, maybe your card is defective!

Funny, I've just deleted everything from my 512mb sd card and yet the pda settings are telling me I've got 19.94 mb in use on the card even though I've nothing on that card? I'm wondering if my settings are correct? Can you set an upload limit onm the xda2?

Ignore last post. No probs with my 512 cards. This 1gb card must be defective. Why else can't I upload more than 715mb of mp3s to the card?

Any tools to recover a Sandisk SD Card?

Hi everyone,
I upgraded my XDA succesfully by using the SD method with a card from my digital camera. After that, I formated the sd card with the card reader then I plugged it in my digital camera.
And here is my problem, the digital camera doesn't recognise anymore this Hi-speed 512 sandisk. I tried everything to recover it but no success at all until now. :twisted:
I understand by using the OSI image tools, the card has been formated in a special way to make space for the file NK.nb1
So if someone has got any similar experience, be welcome to give me any tips for a solution.
Thanks.

i just formatted my card with my xda
and pocked mechanics

My digital camera has the option to format while in the camera, have you checked the built in menus? You could try formatting your card in the card reader with FAT16 if it is FAT 32 at the moment, if it is FAT 16 NOW then try FAT32.

Hi guys,
Thanks for your reply.
Sorry I forgot to say. My XDA card reader and my PC card reader don't have any problem to read or write or format this SD card, Which I did. FAT and FAT 32, but there's no result for my digital camera.
Always the same message: " unable to use the card" and the SD Card was working perfectly before.
One strange thing I have noticed (I think) is that the memory capacity is different now. I get 6 Mb more than before.
Otherwise, yes I tried to format the card with the OS from my digital camera but without any success as the camera doesn't let me any possibility to access to the menu with the card plugged in it. I'm stuck.
Before to use OSI image tools the capacity was;
FAT: 477 MB
After:
FAT: Free space : 507109376 bytes => 483 MB
FAT 32: Free space: 506372096 bytes =>482 MB
I'm just wondering if maybe a header from this SD card was wiped out during the process. Maybe some of you guys know a software who could read and write on this special part of the SD card, then I would compare and maybe repaire it.
Thx

Hi,
Is it possible that someone try to plug a sd card who was used to flash a PDA in a digital camera minolta Z3 or other Z...?
I would be interrested to get a feed back on the result.
Cheers,

Finally after several Emails to (Minolta and Sandisk) I got a valuable answer from Minolta who confirmed my first thought. BTW, Sandisk never replied to me, I’m very disappointed by them. Fortunately, there are others competitors in this sector.
Guess what for the next new SDcard…
So:
On each SD card (Others models certainly too), there are several important information on the boot. This information is necessary to inform the digital camera on the technical specification from the SDcard. If the original boot is missing or corrupted, the digital camera doesn’t recognize the SD card properly and screen the following message “Unable to use this card”.
And here is the solution to recover an original boot for your SD card. You should use SDFormatter V1.1 .
Now my SD card is like a new one(only joking) .
Cheers,

Memory card problems

I really need some help guys. I recently bought a 2gig memory card for my Dash running the Kavana 6.1 update. I later on inserted the card into one of my other phones and formatted it. However, when I view the storage card from Windows Mobile Device Manager, I no longer have my 1 point something gig of memory, but a paltry 966 MBs. Anyone know what happened and if there is a solution? I tried inserting the card into my memory slots using the adapters but no luck, as it never shows up..

wthe device manager might have corrupted the card because the dash is only supposed to have 1gig. cards is my guess and if thats the case u just have to reformatt on a card reader and not use with mobile manager...

try formatting your card in your phone you can use resco explorer to format it

The Dash (out of the box) can take up to 2gb card. Even after changing the ROM it would take a 2gb card. What phone did you use to format the card? if the phone you used to format it could not take a 2gb card it would format it exactly to what you are saying, basically change it to a 1gb card.
Format it in your computer use fat16, do a full format. Hopefully you will be able to erase the new file table that says 1gb and restore it to a 2gb.

Not on Vista you wont. You'll need a XP system... the only other option is to set your view types in windows exploere to show system and hidden files on the storage card then delete them. Then use your dash to format the card. Its a long shot but it might work. If not.. looks like you are in the market for a new 2gb card.

also remember windows never shows the full size of a card or any other form of storage. remember 1 gig is actually 1024 megs. and never shows the reserved system space.

Corrupted my 200gb Micro SD when trying to convert it to internal storage on Shield

I wanted to convert my 200gb micro sd card into internal storage for my Nvidia Shield tablet.For the specifications of the N. Shield it said 128gb was the biggest storage possible for a micro sd card, but I'd seen multiple cases of people using 200gb micro sd cards just fine on the shield.
I started the formatting process ,it got stuck at 20% and then crashed. I restarted my tablet to find that the SD card had become corrupted. I brought a micro sd adaptor and plugged it into the computer. I tried to format it from the computer to find the error message: "The volume does not contain a recognized file system". I check disk management to find that it only has 30mb storage.
I've have tried everything to restore it back to 200gb, but it still shows up as only having 30mb.
This is what I've done so far: 1) Everything diskpart related.
2) Like a dozen SD formatting programs
3) Partition tools have also failed
What do I do now? I don't want $200 down the drain.

You could try using DISKPART on Windows or the disk utility on a MAC and try to repair the volume that way, other than that I think your SD Card is made by SanDisk who has a lifetime no questions asked warranty.
I originally used the Best Buy "Pixtor" branded SanDisk card in my Portable and they replaced it with an Ultra no questions asked, (64GB U1) SD Cards die unfortunately, just call them, don't do what I did and waste 4 hours trying to fix it lol.
P.S. It sounds like the format got to 20% and found a bad sector.

I recently "soft-bricked" a brand new SanDisk 200GB card. I was able to recover the wiped partition. I recommend you try Minitool Parition Manager. If that doesn't work, try Minitool Data Recovery. I had to end up utilizing the Data Recovery program. Now it works, and my 200GB SanDisk is good as new. If you can't seem to repair it, like @Neoistheone2000 said, your warranty will cover it Though it sucks having to go through an exchange process. Amazon is the best for situations like that.

Use any partition utility that is not built into Windows. Minitool per above, any flavor of Gparted, etc. "Real" tools will bring back any bad drive that is not a hardware failure. Ironic to many, Mac's Disk Utility is actually quite capable in this regard, as well.

External microSD Card Slow in LG G3, Fast on PC

I had a 128GB microSD card in my LG G3, a 128GB Samsung EVO Select microSD card. After only a year I was seeing slow read/write benchmark speeds (using A1 SD Bench) & was also seeing some lag so I replaced it with a 128GB Sandisk Extreme Pro. But the speed for the Sandisk is the same.
The app A1 SD Bench shows them both doing Read: 42MB/sec, Write: 38MB/sec. I've seen others that see speeds of 70MB/sec and higher. Both cards are formatted exFAT.
I'm concerned that maybe I've made tweaks using Trickster Mod that might have slowed the card down? Or could there be another reason? Thanks to anyone that can help.

I don't know what's causing that. I also had a problem with my LG G3 851 and the SD card. Basically the SD card died and I can't read anything from it nor reformat nor anything. It was a 128gb SanDisk, one of the faster ones, running Lineage OS 16.1. I ended up just figuring I didn't really need the SD card in my case. I'm sorry your's is running slow. All I can say is try to factory reset the phone back to stock and see if that solves the problem.

Factory reset ("saying a prayer") is too drastic a step and rarely solves anything, but I did solve the problem.
Using Desk Genius on my PC I created a single partition on the microSD card (Most people just format, you must create a partition first). Then using Windows 7 disk format I formatted the microSD card for exFAT, 128K cluster size. Now the microSD card flies!!!
It took me a full weekend of testing to come up with this. I tried using various tools to partition, and various tools to format, all with different cluster sizes. This gave me the best performance.
Tools included Disk Genius, EaseUS Partition Master, MiniTool Partition Wizard, Windows 7 built-in tools, and a lot more.
EDIT: I forgot to add, after formatting you need to go back into Disk Genius and do a 4K alignment check (it's in the Tools menu). Alignment to 4K boundaries prevents extra read/write cycles and improves performance.
If it fails 4K alignment then you need to partition and reformat all over again.

That's awesome! I'll keep that in mind if I go get another SD card some day. I didn't realize that the format could mess up the read/write speeds. I wonder if a wrong format made my SD card die. If I do get another SD card, this time I'll keep the receipt in case it stops working again. I had a PNY SD card die on me in my Surface 3 as well.

It's not just the reformat, you have to repartition as well. And I forgot to mention you need to check for 4K alignment too (I edited my OP).
