Question about SD cards not reading everything

Hey everybody its Cardi Lyone here with a pondering question for all you super developers. i recently bought an SD card off of ebay that was a 32gb for my htc evo. granted it came from china so i got it for round 10 bucks but thats not the problem. the card DOES WORK AND read at 32gbs when entered in the phone and threw my laptop; but when i try to copy everything on my stock card to that card everything usually everything reads apps ect, but my music and pictures. i have no idea whats going on thought it was kinda weird. looking for a little feedback before i go out and spend good knows how much for another 32 gb card. thanks for reading and helping.

Hmmm....I don't have any idea, but did you try reformatting it as FAT32? Sorry, that's all I could think of.

The sd card is a fraud. Its not really 32 gigs.

sd cards can be hacked so they say they hold so much data but what it does is just keep writing over the same blocks. There are programs to test the actual size try... h2testw... google it, its a free program it takes awhile since it tries to read and write the the full amount of the card to see its real capacity. my guess is that you have a 512mb card hacked to say 32gb... sorry man

i was figuring so, guess i didnt want to think it was true. but thanks for all your help on the matter. if anyone has a 16 or higher laying around leave me message maybe we could work something out!

[Q] SD Card help?

i just got a new sd card switch to a 32g but for some reason when i try to put ALL my fav tunes on there it always seems to screw up and not copy most of them...what am i doing wrong i know i have enough space..

Maybe try putting the songs in small portions if you have a lot.. other than that I don't know, bro.

Did you try formatting the card? Where did you buy it? I have heard many many many times that ebay is infiltrated with fraud 32gb cards. They are really 4 or 8gb or something like that. When you mount the card in your computer or phone, what does it show the total size as?

it shows the right amount...

Fraud cards still show the "right" amount as far as I know. Dunno if they do in the phone though

I agree that it could be a fake card. Where did you buy it from and how much did you pay?

mobile shack, about $30

$30 for a 32 gig definitely sounds fishy.

You have been EVOfied.

You can test your card's real capacity with a utility like h2test, which will write files until it's full and then verify them. Though you've basically already verified it...if it consistently stops writing files at a certain capacity, that's probably the true capacity of the card. As others have said, if you bought it from ebay, it's common.

Don't let the German scare you. It supports English.

Just went through this with a Wintec card bought from Fry's. Here's what will happen with your card, too:
Code:
while (patience == good)
{
Card will spontaneously corrupt data;
Reformat card;
Restore data from back (you do have a backup, right?);
}
beat card into powder with a ball-peen hammer;
I spent $119 for my card and this happened. Return it if you can.

I used to get corrupted stuff too. What I did that stopped it for me was put a thick piece of paper on top of the card and into the slot. When the battery was on top of the card, out would keep it from moving. I suspected the card and phone contacts weren't staying firmly set. If a write cycle happened when the connection was intermittent, corrupt files and or file allocation table.

Is the microSD card in the Evo when you transfer all that stuff to it? If so, it might be worth a shot to take it out and just use a standalone card reader or USB adapter to hook it up to your computer and then transfer that way. No idea if it would make a difference, but just another thing you can try.

[Q]HTC Desire HD SD Card Un-mounted Itself?[Q]

Hi XDA, seriously problem here that I really, really need to fix.
My father left his phone at home for the FIRST time ever today, his HTC Desire HD was one of the first in the UK, he go it the first day it came out. Today he forgot to take his phone to work, so I put it on charge for him and left for school. He came home halfway through the day to find a warning in the notification bar alerting him that the SD Card had been un-mounted. On seeing this he immidiatley blamed me, as any father would do to a son that enjoys messing around with electronics, however after taking a closer look I noticed that the phone will accept any card except the one that was in it when it unmounted itself at some point within the day.
The card that broke, is the origional Samsung 8GB that came with it (on Orange anyway ~ unbranded as first in UK FTW) when the Samsung Card is inserted all the stats about the card show as Unavailable, and the phone doesn't even recognise a card as being inserted, the same happens when the SD Card is plugged into my computer running Ubuntu & Windows. The card is not recognised at all, infact Ubuntu thought I inserted an empty SD Reader, and thats from Ubuntu! My dad has so much saved to that SD Card, like literally 5 months of holidays and things, I know he should have made back-up's, but is there anyway we could get this back. Thanks.

Hey i had a simmaler problem but i fixed it with my 16gb micro sdcard by takeing it out of my phone and pluging it into my lapyop and move all the files off the sdcard and onto the desktop and then move then back and then put it back into the phone and turn it on and see if it worked
If it didnt please responed and tell me the exact message it says

Hey Man,
I would do this, but my computer doesn't detect the MicroSD even if its in a SD Reader and plugged into my PC?

I had a similar problem... after i got my DHD, I bought a 16gb card for storage. I used this for about 4 months then I started to get the dismount messages every now and then, particularly when the card was being used a lot (playing music from it especially). Then a few days later it would do it after every boot.
My PC can see the files on the card, but trying to copy them off throws an error. I can't format the card either. I have since bought a new one and that is working fine, so it may have just been a faulty card.

It is HTC's fault, bug in the rom causes that. Your father should get an OTA update any time soon that will prevent it from happening again. You can format the SD using a PC and a card reader, it might just revive the card.

If you want to retreive data on the SD do not format or delete the partition.
Try to use a "data rcovery" tool first.
But if it's not recognise at all (like a piece of plastic and not as a non formated sd) all data maybe lost.
Usually OS corrupt the SD, it doesn't destroy it. If it's dead it not your fault or the OS fault. It's just no luck (try to explain this to dad ).

And beside I think its an San disc not an samsung, like I have, and try read it with partition manager. If not you can get a new one. And never buy Kingston cards, I had 5 of them and all died in few weeks.

I do not think so, all Kingston was a waste of money for me, but my sandisc m2 micro sd are working fine for 6 years with no problem at all.

Well, both Kingston and SanDisk have worked well for me, and the price is usually almost the same. The difference is that Kingston gives absolutely awesome warranty, and the cards are fast has h*ll. My Class4 Kingston reads 21 megs per second, and writes 12 megs per second.

Loads of bootleg Kingston cards in England and I never noticed any kind of warranty on them while it was the most tempting thing on the ones I used to buy from Finland

Thanks for the information, i've sent an E-Mail to HTC complaining about it. Hopefully they will see the light, and send a new SD-Card as it was shipped with the phone from HTC.

SD Card Removed Unexpectedly when Connected to PC?

I've looked around a bit, and correct me if I'm wrong, but it doesn't seem like anyone else has my problem.
Long story short, I've got a 8GB Class 4 Sandisk SD card, and it worked well for the first few weeks. However, as of recently, anytime I connect to my PC in any way and try to transfer files over using USB or Bluetooth, it fails due to the unexpected removal of my SD Card. This is without me physically removing it of course.
I've tried formatting using default settings, and I don't know what else to try... can anyone shed some light here?

Have you tried another SD?
If you have and problem is still there, I would try a factory reset.
If after all this effort your problem is still not resolved, then i would say a call to HTC is your best solution as it could be hardware related.
Oh couple more things:
Try a different USB cable.
Try a different port or pc.

Okay, I tried it with the stock microSD 2gb, and I didn't get this problem ... basically it just means I've got a bad 8gb?

Be aware there has been countless reports of fake sandisk SD cards being sold everywhere including eBay and Amazon's market place.
So before purchasing a new card Google how to spot a fake sandisk and it should give you an idea of what to look for or not.

I had also faced this situation ...i changed with class 2...nw it working like charm...

I purchased mine from London Drugs, not sure if you know it, but it is a trustworthy place so I doubt my card is fake.
One more thing for clarification, do you think that setting the phone so that it auto installs to SD could have some effect? I set mine up like that due to the lack of internal storage. Thanks for the responses!

i didnt have this issues before hope u can fix it

Auto install to SD should have no effect mate.
Also the fake card situation - well they have been sold by legitimate sellers believing them to be genuine, not trying to deceive customers.
Apparently the market has been flooded with them.
I read about it a couple of months back.
Not saying yours is fake, was just saying your average user wouldn't notice at all.

External SD card disappeared...

So I woke up this morning, phone says SD card unplugged, please insert new...knowing that I obviously did not remove my external sd card I then proceed to check
Settings, Storage --> (nothing shows up)
Boot into recovery --> can't mount external SD card
plug it into PC --> nothing shows up
So now the question is, do I have a bad/dead micro SD card or else?
I am on CM10 which is updated nightly, that might have something to do with the SD card, I dont know.

Edit-- missed where you said you already tried directly from computer.
Might just be a dead card.

Unless it is just not being assigned a drive letter on the pc, the card is toast. If you are using windows you can got to the disk management snap in from the administrative tools and see if it is listed at all, if it doesn't show there it is fubar. Easiest way to get there is right click computer, manage, disk management. For linux or mac im sure there is a similar tool but i couldn't tell how to get there or use it.

Which recovery do you have? Same thing happened to me on 6.0.1.4 Touch. Computer still saw the card, so i pulled everything off the card, reformatted with the computer, then changed recovery. Phone saw it after that and no more problems since.

Thats just the nature of flash memory, eventually it does go bad and unlike mechanical drives which often give plenty of warning of impending failure flash rarely does. Granted 2 months is obviously not acceptable it could be just a freak thing or maybe just an inferior brand. It is also highly susceptible to static discharge, especially in a SD card type format where the pins are exposed. Although possible, i doubt a static shock happened inside the phone but it could have possibly been damaged and just took a while to completely fail.

I used this to format my 64gig chip

Get a new card...i would also check on any warranty offered by the manufacturer, that goes for OP too. Depending on the brand there may be a 1 year or even lifetime warranty, some of the lesser brands might not have a warranty at all. Although i haven't followed my own advice in this category as the last 2 16 GB micro SD's i've purchased have been fairly cheap class 10's, you more often than not get what you pay for. I would also recommend going for the class 10 cards, not only do they have the fastest transfer speeds (and maybe because of this) they seem to be more reliable then their slower cousins.

Although i've never had one of their SD's, Kingston is one of the top tier memory companies and carry lifetime warranties on most (if not all) of their products. At the very least i would expect a year.

In my experience SanDisk is considered a cheapo brand but they have been around long enough to have overcome that reputation. I would imagine they also have a warranty program although i can't speak from personal experience, definitely worth checking into.

Im quite sure that my kingstone sd card is genuine..
Any possibilities that my S3 killed it?

I don't think SanDisk is a cheapo brand since they have been making great cards for a long time. They have a great warranty program. They will replace anything within a year for sure. I had one that you couldn't read the serial number on so they still replaced it.
SanDisk has a problem by being the most well known microsd, they are faked by chinese companies all the time and those fakes look just like the real ones. Therefore, you buy a fake, paying real prices, that looks real, and you blame SanDisk. I think that was what happened in my experience with a dead card, and they still replaced it.

You can't just format it from "My Computer". You will have to go into device manager and find it, then format it that way. Otherwise it will not work.
