SD 4GB Problem

Hello!
I've just recieved a brand new OEM SD 4GB 150x but I have a problem with it!
I tried to access it trough my laptop (Aopen 1557-G) but nothing happens.
After I insert it on SD slot, the laptop freezes for a sec or two and then on My Computer appears a icon saying SD /MMC. I try to open it and says no disk inserted!
Then, I've tried on a Mio A201 and on explorer I can't access it either (The Storage card doesnt happer).
I was wondering if there is a problem with SD (I want to use it on HTC Universal, but mine as gone to warrancy for battery replacement, so I cant test it on it).
Do you think is possible that my card reader on laptop doesnt recognize it because is 4Gb? Should I try it with a USB card reader?
Doesnt Mio A201 support 4GB SD?
I want to be sure that it's faulty before I'll send it back to USA for replacement. A month of delay more extra expenses of shipment.
Thanks for your help.

It's quite possible that the card reader in your laptop just doesn't support that size of SD card. I'd suggest testing it in any other device you can.
Just out of curiosity, how much did you pay for the 4Gb SD card? I work at CEX in Brighton, and we had a 4Gb 150x SD card in a while ago, which was up for sale for I think 90 pounds or so. (All our items are second-hand, bought from customers. I checked on the price of 512Mb cards a while back - ours were 10 quid at the time, Jessops 5 doors down was selling them for 50!)

I'm guessing you got your SD from eBay, from a dude called fastmemoryman. OEM Samsung 150x from the USA
Anyway, I've had no problems with mine, it works with both my computer's SD card readers (both USB though), my Magician (with some tweaking - a manafacturing fault of the Magician I think), my Himalaya and my Dell Axim x30. You probably will need a USB card reader, as laptop card readers are typically weak.
If it refuses to work in your Mio or Wizard, I suggest you try partitioning the card into two using something like Paragon Partition Manager, so that the card appears as two 2GB cards instead of one 4GB card (as many devices have problems handling 4GB cards).

what i usually do if the sd card is not recognized i try it on a camera and try to format it thru that, then i insert it to my pda and re-format it again with resco. i am using a 4Gb 150x Transcend card on my Uni no problems

Yes!
I bought and successfully using "SD Transcend 4Gb/150x" in my device (on photo) with FAT System.
My "Epson_RX-620", included to big PC, not viewing her absolutely precisely - as you have described!
Offers to format and can not open!
Here is present only one exit - to use cards with this speed 150x -
only on elementary USB-adapters without additional drivers -
only by means of adapted drivers of System (WXP).

I just bought a PQI 4gb SD card with no problems for $70 USD, www.newegg.com has alot of selections, ranging from $60 - $80 USD.

It's a advertise of concrete shop, and it haven't nothing common with described problem.
Many shops is present in all countries, and to this sellers from another city (country!!!)
there is no sense to go - to pay for a road (or delivery) - more expensively.
I thought, that here there is no advertising...
And I bought my card of prestigious firm (made in Taiwan) -
for $-57 IN RUSSIA!!! - and what - all to go to Russia?
But if who want - welcome to Russia, please!
(not for sake of card - a simple so)

I bought the same OEM 150x samsung SD card from ebay two months ago. I started having problems with it - first my PC reader wouldnt reader it, although it did initially, and then my Universal wouldn't read it - it would freeze when i put it into the phone. I have sent it back now for a replacement.

hi you need to download new drivers for the card reader in your laptop. I had to do it to my acer found them on the HP website under texas instruments 4 in 1 reader but search through till you find the 4 gig driver.

HELP!! my 1gig storage card is maxed out at 512mb

morning/afternoon/evening to all my fellow ppc users....
i have a question that probly has a simple answer, but many hours of scouring the forums and google havent quite given me a concrete answer on this....
i recently bought a 1 gig micro sd with the adaptors for full size and mini sd (my phone uses the mini), and yet when it gets close to 512mb, it acts as tho its full.
the answers i have gotten on correcting this is to either reset my device fully again and start all over, or to attempt to reformat my sd card, which is the simpler, but i have heard that doing that sometimes makes it unreadable for ppc.
any suggestions or advice?

I've reformatted my cards lots of times and never had a problem. As long as you reformat it in FAT32 or FAT16 you shouldn't have a problem either.

One other possibility is that you have a 512MB card that's been marked/hacked to appear as a 1GB. This is a big problem on eBay as there are many sellers who do this.

i would hope not.... i bought this from a legit phone dealer and when placed in my comp it shows the space of a 1gig..... hopefully xeno's idea works.

Guys,
The bad news is that a lot of the Sandisk 1Gb MicroSD cards sold a few months ago on ebay were in fact 512Mb cards remarked as 1Gb !!! Quite a few unsuspecting dealers also got caught with stock - so your reputable dealer just may have been duped too...
First thing to try is to put the card into the SD adaptor.. Into a decent USB card reader on your PC. We use Paragon Disk Tools to actually fix / remove / repair the partition table on the memory card.. This is NOT fixed by simply formatting the card in Windows... Once your partition table is sorted, format the card as FAT16 or FAT32 (to suit).. Don't use Quick Format.
If this went well, your card is ready to go back into the PDA.. If the format hangs, then the card is either faulty or dodgey (!!)..
Good luck

'Dead' 16GB SD card?

Hi all,
Happily listening to music with Core Player on the TP2 I received last Saturday and the phone lit up with a message from Core Player that it wanted to update my media library, following the removal of the SD Card.
Suffice to say, I was confused: no chance with the SD card hidden under the battery cover that it could have been loose and fallen out but checking through File Manager on the phone, the SD card can't be seen at all.
Put said card into an adapter and then card reader on my PC; it comes up to suggest there is no card inserted: put the same card via adapter into my digital camera and the camera refuses to even turn on with the card in.
It's a duff card I'm sure - bit peeved since it wasn't that old but meh: don't trust all eBay sellers selling 'genuine' SanDisk products I guess - however, whilst I await the arrival of a new one, could it be my TP2 that has damaged the card in some way? Has anyone else noted problems with the TP2 and higher capacity SD cards?

FlashROM based cards only have a certain number of writes. Same goes for SSDs. They should have a way to track number of writes to cards. I've had official Sandisk cards go bad on me within the first year too. Don't forget that static shocks from your clothes can actually damage the card. Also don't forget that your phone can corrupt your data if it's in the middle of a read/write op and you remove the card.

Thanks for your thoughts mate: it wasn't removed from the phone and the phone only had CorePlayer running on it at the time - so I don't think it was anything I'd done
I think I got duped by someone on eBay selling a 'Geninue' Sandisk card that perhaps wasn't - I've read here than Danetec are also quite good so I've ordered one of them directly: fingers crossed I have more luck with my second one!
I was more concerned with it possibly being my phone - I read a month or so back on the Diamond2 forum that 16GB cards didn't work so well with that phone and wondered if any forumites here had noted any issues with the TP2 and certain SD cards, thats all...

it happened to me last weekend, due to an automatic update of go news touch which went wrong.
no way to see or format the card on the ppc or my netbook. I had to go back home, put it into a usb adaptor, and finally format it with mu desktop pc. my little cer netbook couldn't detect it, and locked up each time I tried formatting it, even from cmd console. but on desktop with adaptor it went just fine.
hope you'll be able to resolve - my sandisk card was 20 days old, 65€ worth, and having it toasted isn't something I would wish to anyone

In this case, it's not even recognised - via a card reader, active sync or inside another device: this one I think is lost Meh, it's only money

Hi All
Paulplex, don't feel you are alone, this happened to me too with a genuine Sandisk 16gb card. It worked last thing at night, went to access it in the morning and it was dead - just 3 months old with no issues at all up to that point.
The solution was replace it as it would not recognise via a reader in the pc either - completely useless....
The cause? Who knows, i do suspect the TP 2 though as i had no issue with it on my old Dopod 838 pro for the first 2 months since new.

[Q] Phone nor computer will recognize my micro sdhc card

I have a HTC EVO 4G which is supposed to support up to 32 gb memory so I purchased a 32 GB micro card on ebay a few months ago and come to find out, it was a fake. I bought another one and filled it up to about 29gb and it worked fine for a few days then it just stopped working and now the phone I had it in won't recognize it's in there nor will my laptop. The difference being that at least my computer sees that something is there but won't read it i.e. it says drive h: in computer when I put it in but says insert drive when I try to access it. Also, it starts to get extremely hot after a few seconds to a minute. My husband has one as well from the same company, the same brand and has 30gb of stuff on his and hasn't had a problem yet (this has been at least three months ago now). Before anyone says it; yes it is 32gb, I tested it before I put it in my phone (thus the fact that I had 29gb of stuff on it before it went screwy), yes it is in the slot properly or else it wouldn't even say H: drive at all and no, my card reader isn't bad and yes it is compatible with my computer and the card as it is what I used to put the stuff on it originally and it still works fine with my husbands 32gb card and all of my other cards. My computer works fine with his card and it worked fine with mine before it went bad. Now, all of that being said; is there anything that can be done or will I have to just buy a new one?

There are programs out there that allow low level access to the drives that windows does not.
Get ahold of one of them and see if you can wipe it and repartition it.

There has always been a problem with the eBay cards, that's why they are cheaper, because not all memory cards are created equal. Unfortunately, my guess is that this boils down to you get what you paid for. There really isn't much you can do other than try to format the card. My experience is that you have lost the data on that card for good, and that more than likely, the card is dead. Sorry, hopefully someone may have a better answer for you.

could you provide program names? I'm very interested in something like this.

Norton Partition Magic
Acronis Disk Director
Paragon Partition Manager
Those are all commercial packages, though. If you want something free, you can try GParted, a bootable Linux CD.

Anyone know of any tools to try to recover data on a card like this? PC doesn't recognize card.

[Q] SD Card Issue (Yes, still not solved)

For the longest time, I have been unable to use my 128GB Sandisk MicroSD card properly with my GN4. I have tried SD card fixes, foldermount, and messed with the platform.xml file as well. What I used to do back in the days of ICS/Pre KitKat 4.4.4 was take the SD card and plug it into my computer (via SD card adapter) and transfer the files I needed directly since it takes a while longer if I connected the phone to the computer. I can still transfer files to the microSD card if I plug it in, but they are not able to be read. This is starting to piss me off as I have a lot of music that I would like to store on the card. Anyone have anything else they can suggest?
I used foldermount last week - Some of the music files work properly, while some don't play and I get the message "unable to play this file."
I bought this card brand new and I'm hoping it's not "a bad card"

I also use a 128gb Sandisk Card, the "ultra" I believe. I never had a problem with it, I just came from the Note 3 and put it in the Note 4 with no issues. Is yours the "Ultra" also?

Maybe a bad card. I got 3 fake ones on eBay before I got a real one. I flipped out on the sellers and reported them. Each time I got a bad one I spent hrs copying data over to the 128. I would copy over around 20 gb, and another 20 and so on. When I went to look at the files that I had first put on there they would be gone. There are programs u can download for free. Just Google how to tell if sd card is fake. A fake card is really a 2/4/8/16/32 card changed to look and act like a 128 and once it hits it's limit that u don't know what that is, the earlier data that was put on the card, disappears.
Here is a link for a program I used:
http://forum.xda-developers.com/showthread.php?t=730285
This happened to me back in Oct/Nov when note 4 was launched. I ended up paying $120 on eBay for SanDisk's highest r/w 128 gb card.
The first seller claimed he didn't know they were fake and promised to stop selling them if I retracted my bad feedback as it was the only bad feedback he had ever received. Once I saw they were removed from his selling list I retracted the feedback. The second and third sellers I was not nice to, did not even have to send them back the pos card. My response was something like refund my ****ing money now for selling me this fake ****ing sd card. Ten minutes later both had gave me my money back. Assholes. After I got a good one I had contacted the first seller again and explained how much trouble I had and the scam artists there are on eBay. I feel that he was genuinely sorry and had no idea. He also stopped doing business with who he was getting the fake cards.
This good card has been great, note 4 32 gb internal, 128 external, both full, zero problems.

Plug it into your computer and check if it's formatted correctly (fat32 vs NTFS). That might solve the problem. Don't quote me, but I think it needs fat32.

Yes it does need to be fat 32.
Also if is fake, u might format it, move data, insert in phone, and it says it's not readable and needs to be formatted.

Yes mine is the ultra version as well (in red letters on the micro sd card)

the two options are exFAT and NTFS. I formatted on exFAT and it seemed to be working just fine until today.
So I use my sd card as direct storage for when pictures are taken. I was at dinner today and took pictures of the food we ate. All of a sudden when I go to the Gallery, I see a black and grey image with an exclamation point for the pictures taken at dinner with the exception of one. I am wondering whether Samsung/Google is releasing updates that put the phone back into the main issue of not being able to R/W to the external sd card? I don't know what else could be the reason. I also tested the card to make sure it wasn't fake. SO DAMN FRUSTRATING!

Shouldn't have to format it. Already exfat when it comes. If it's real, contact sandisk with pictures of the card and it's serial number and a copy of the receipt. They will replace it.
