Problems w/ 2GB Sandisk Mini-SD

Hi All,
Just wondering if anyone else is getting intermittent issues w/ their mini-SD card.
I've lost essentially all my data on my 2GB Sandisk on three separate occasions. I have formatted different ways (once w/ RescoExp, and then FAT32 on 2 computers), been v. careful closing my apps and minimizing the amount of writing to the card.
Does anyone have any suggestions?
Sandisk's comments are as follows:
"This is a known issue with the devices when they work this way with 2GB and up memory cards. Usually in this cases you just need to contact the manufacturer of the device that you having issues with the reading on, to find out about compatability and what kind of firmware update do you need."
Thanks!

I haven't had any issues with my SanDisk 2gb card using my K-JAM.
Now on other pdas and with other cards, I have had the "lose everything" problem. Two reasons I had...storing email attachments on the and having the unit crash while accessing the card.
My onyl problem with the larger card is my laptop doesn't recognize it

I lost all of my data just last week off of my card, I went ahead ahd reformatted it again, not sure whats wrong with the 2gb cards

I haven't had a single issue with my 2GB TOPRAM card. I have had a few issues where the device doesn't see it (I assume) and renames the folder to Storage Card 2 and creates a new folder "STorage Card" with nothing there. It happens rarely and when it does, I just take the card out, rename the bad folder to StorageCardOld then insert the card again. This corrects the issue. I use the card very heavily and have had it since around the end of January.

I too have had this problem. I hope my suggestion helps.
I've had issues in the past with Sandisk flash cards. My problems were the same as yours until some helpful spark suggested I do a disk error check using windows (right click on drive in explorer>properties>Tools>Error Checking). Format the card and then run the disk check, apparently some Sandisk flash cards exhibit not so rare sector problems. His explanation (the science bit of which I have long since forgotten) was that that by running the disk check, the utility automatically marks the error causing sectors as unusable. The disk can then be used as normal after that, but any reformatting should have the disk check run again to mark the sectors once more.
This has helped me in 2 out of three occasions and so may or may not work for you. Still, I hope this solves your problem.

BS answer from Sandisk
Leighj, that's a BS answer from Sandisk. I guess it would never occur to them that your SD card is defective. Try another card in your machine or that card in another PDA phone if you have either of those options, but if not contact Sandisk and get a replacement. It should have a lifetime warranty, or at least several years.

Have to agree with iclick. My Sandisk cards were basically defective and how I got them running was a workaround and not a solution.

Yes - I wasn't too happy with their response either. Anyway, I just ran through error checking before & after reformatting. Hopefully that works - if not I'm off to shop for a new card. Either way, it's probably the last Sandisk mem card I purchase.
Thanks for your comments!

I have a Sandisk 2Gb Mini-SD as well and I've not had any issues with it so far. If it helps, I've left the card in the factory default format of FAT only - not FAT32. Try putting yours back to FAT and see if you still get any issues. Depending on what program you use the option you want might be labelled as FAT16 instead of just FAT.

I have Sandisk Ultra 2G miniSD, I don't have any problems untill recently. Whenever I try to add my storage capacity to more than 60%, 1GB or more, it gave me an error because the file is write protected and then not responding file transfer.
First, I taught my file is broken, but when I removed other files from the mini SD card and then add it ..... it's work. I used a factory Format type. Do anyone have this problems :?:

Well after contacted Sandisk customer services regarding my memory. They asked me to reformat my card and I did that. through my laptop, but it said that windows cannot complete the format. Now the card is dead. :twisted:

Do the mini sd cards have a lock?
Do these cards have a lock on them? My old SD cards had a slider but I don't see one on the sandisk card.

The miniSD doesn't have a lock, but the miniSD-to-SD adapter does have a slider just like a real SD.

if i take my sd out for any reason it will often take a few goes to get it recognised by the mini s again. I have to remove/insert it as many as 10 times.

Hd2 has ruined my 8gb sd card

Alrite peeps,
I hope someone can help me here as I have had no luck anywhere else.
I have had the hd2 for over a month now, it came with a 2gb Sdhc card but I decided to purchase an 8gb sandisk sdhc card.
Ok, I have not encountered any problems so far until today as I scrolled to view some pictures it froze at a pic for 5secs then suddenly to my shock I discovered that it had deleted all my files from my sd card! Now I took it out when I put it back it in, it requested a reformat to make the card readable! So I tried it on my Pc and again it asked to reformat- I had no choice to reformat when I did this I had an error message unable to reformat?! I noticed the capacity had also changed to 30.6mb and when I tried to reformat it in the hd2 it was succesful but still not readable ! Has Anyone else come across this problem and what can I do or is my card messed up?might check if it came with warranty.
Thanks in advance
P.s I'm running the tmobile 1.72 stock rom if that's makes any difference.

Yes, I had the same problem. And it turned out to be a fake card. Where did you buy it?

I had the same problem with the 8Gb card that came in the box from HTC. I have opened a case with HTC, and waiting to see what they say...

incredible ... the same thing happened to me, my guess the card is a fake, yet how does it work before that? I dont know how much data I had in there, it was not a lot, but the moment I tried to put about 15 songs in there, thats when it crashed afterward when I tried to play the songs. I havent had it for 2 weeks when it happened.

Omg.. that is serious thing...

Try to get your pictures back!
I work in a supermarket for home electronics and we've several failures of SD-/Memorycards per week. Even if you've formatted your (micro) SD-card, you can get your data back (esp. pictures) in the most cases. Very important: DO NOT USE THE CARD B4 MAKE A RESCUE TRIAL!
I use a free programm called DIR (Digital Image Recovery) in a special free version (from Foto Erhardt search via heise.de) to rescue the datas. It seems rly lowlevel but fails if it finds heavy memory errors. In such cases I try the free version of recuva, which you could use for other files too. PC Inspector Smart Recovery is the second possibility, but seems to me a bit unstable.
However, in a Windows OS you have to expect in evry second with a bluescreen, data loss, weird errors...
P.S.: All progs should be available in English or as ML.

SD CARD
Well i have to say this my card is also a disgrace as sandisk was bought with one of the store here in cambodia together with my HTC HD2 and after 2 days my whole input in it gone and requested for reformat..i did and tried for how many times then no luck at all. i returned to the shop and explain to them luckily they understood. same brand but till now its ok 1month passed

I have to say from experience that i wouldn't be surprised if all these failed cards were sandisk branded. I've had 3 sandisk sd cards of varying sizes over the years and they have all failed. They were all bought from reputable stores and never got using for anything other than data storage so spent most of their time in the plastic cases. Since then i've stayed away from sandisk kit and never had a failure and saved some cash in the process coz sandisk also like to charge you more.
This maybe something to test.

exactly the same problem here. Even the 30,6 Mb. matches. I bought from e-Bay, some prik in Korea. escalated at Paypal bust still no money back

Moschino02: change the title of the thread, please
not the HD2 ruins the microsd cards... the cards gives problems(fake / defective / no name brands)

i have had problems with a sd card. especially when files are damaged
look here. this is a formatter specially for sd cards.

run this with your card in a card reader after a recovery described above.
see if it helps to get the card working

I opened a case at eBay (within 45 days) and they returned my money in a day (great service)! My seller was from Hong Kong and pretended to be a friendly, reasonable guy, but by the time he knew I had returned the card there was no communication anymore whatsoever. As soon as I told the seller about the problem he had the item removed from eBay so I couldn't give negative feedback. eBay mailed me a warning about that too, but by that time I had already paid, received and returned the item.

Ok maybe it was not the hd2 but a faulty card I don't know? Please ignore the title(Im not sure how to amend it) Thanks for the zip file il give that a go..
I see that others have experienced this fault.I was always aware of fake cards prior to making the purchase off eBay, i thought it was geniune as it stated that it had a 5year warranty however the uk business shop/seller who specialises in these products has not replied to me since the fault in regards with the warranty. So I'm having doubts now
Anyways, just be careful and Sync regularly - luckily I did not have much on there exact a few apps and a few pics.

Now I am not so sure if my 8gb micro sd hc card is a fake after all, a friend has a similar card and they look exactly alike. I got my card bundled with the phone, and it did work for quite a while until I copied some music into it, and the card failed after I tried to play the songs. Now my notebook doesnt recognize the micro sd card (sd card adaptor) therefore cant format it since no disk detected, and my hd2 formatted it to a 30mb capacity yet i cant see it in file explorer.

same problem for me. have been using the bundled 8gb card for a mth when suddenly it died 5days ago. I panicked and tried reading it on my laptop. nothing detected. I thought all my files are gone for good. I pulled out the card and reinserted over 10times. all of a sudden, autoplay started and the card and its files were detected! immediately copied and backed up all my files onto my laptop.
true enough to my prediction, this morning I woke up and the card died once more... this time its dead for real. changed to a Toshiba 4gb card this time..
could it be its the phone causing cards to corrupt? regardless of brand? so many ppl have this problem.

Same for me here,
I think it's related to cht scheduler or to cht. I've read something @ pocketpc.ch
so now my 16 gig scandisc sd-card only has 30.6mb
I'm gonna send it back...

I wonder how many of you guys do not use the safely remove hardware or the eject option when you remove your phone from your PC....
I have a multitude of microSD cards and ALL of them still work and most of them are sandisk cards....
failure to use the safely remove hardware or eject option will always end in the card getting corrupted. It may not happen the first time but it will eventually happen and when it does get corrupted the HD2 will not show the card as being present until it is formatted.

Here is something intresting somebody wrote in the thread "Dojomaster1984" linked to:
Ravishan2008 said:
Hey Guys!!
I work at a retails shop where we sell heaps of memory cards and cameras a day .. So im pretty experienced with this issue. The microSD card you get with HTC HD2 is a Class (4) card, which transfers about 5mb/s. which means that it has higher transfer rate compared to the normal everyday microSD cards you buy from your retail shops/ebay which are Class (2) which transfers about 2mb/s.
This is the reason that your HD2 kills all those Class (2) cards.. because when the phone doesn't get the enough transfer rate to read.. after couple of days they all stuff up.
Recommendations:
Try getting the new PANASONIC (JAPANESE MADE) microSD card which has a transfer rate for about 20mb/s these cards will work like butter..

so if this guy is right the HD2 only wants class 4 cards...
I for myself bought a class 2, that died (it was a fault, I did want at least a class 4 one)
so good luck altogether!

[Q] another sd card trashed

i am now on my fourth 8Gig micro card this on is trancend and the other three are sandisk i was using the phone this morning fine i have just gone to use it again less than an hour later and it wants me to format i have checkd the card in the phone settings and it says no sd card installed any ideas as i am getting narked off with paying out for new cards every few months

I am having a similar problem. I am on my second card and I have had random photo's corrupt then disappear. ??? I don't know why. Any Ideas?

I use a Duracell card and have never had any problems, did you format the cards before first use ? ... have you tried to format the cards that are not reading.
I work with sd cards all day loading o/s and apps to industrial tocuhscreens and it's very rare to get a totally trashed card.

i formatted it on the hd2 and it still shows no sd card when i put it in a card reader it shows 36meg

if that works then you could insert it back into the hd2 and try to use the htc format software again.

[Q] Memory Issue

So I have a 2gb card in my HD2 right now while running live and according to my sync with my computer, i have .16 gigs left on it.
Isn't there memory onboard the HD2? I know that WP7 uses the memory from the card, but i would at least think it would use some of the memory from the HD2. Do I need to go buy a larger card? I mean I hate to spend $20 on a card if I don't need to. Right now im at the point where I cannot even transfer a photo.

WP7 in it's present incarnation only recognizes and uses 512MB of the the HD2's 1GB so you need a larger SD card if you have one. What happened to your factory SD that came with the HD2...I believe it was a 4GB microSD?

I got this phone for free, so im using an old sd card i had laying around. im gonna probably just go to radio shack while they are having this sale to get the 16g scan disk.

Here is a question. In my sync, it says the capacity on my card is .16g, I had android on there before. Is android still on there? If so, is there a way to remove it? i want to make sure i am getting all the memory out of my card

WP7 installation is supposed to reformat your SD card. In Zune, under view settings or one of the lists of what you can you do with your phone, there is a way to view how much memory you have to play with and also be able to re-allocate memory for specific uses. Check it out.

I cant use zune since i have an Apple iMac. Im using the windows phone 7 connector software off the windows site. It supposedly is the zune version for mac. I just find it hard to believe that ONLY the rom is taking up 2gb of space.

OK, very interesting senerio here. I took out SD card and booted up the phone. The phone actually loaded into windows just fine. Not only that, my wifi was detected. But with the SD card in, no wifi. My SD card must not work

yeah that is correct, your SD card hasnt been recognised at the initial setup, you need to try one of two things, try formatting the card in a digital camera (to be honest even this isnt a great idea) or two, you need a new SD card
SD cards even within the same brands and models may or may not work, some will not install at all, others will install but with issues, wifi, random reboots, lagging, to name a few.
The reason i mention the formating isnt an ideal solution is because, yes it may work, but the underlying issue of the card not originally working is still there, all you have done is moved the bar a bit, the card its self may still generate errors.

Well, I have tried the 3, 2g SD cards I had from getting phones. I also went and bought a $30 SD card and it did not work, so I returned it and got a different $30 SD card, which also did not work.
I am getting pretty fed up.
Does anyone have a spare SD card, that they know works that they want to sell/give me? I don't care the size, i just want to be able to load peoples pictures into the phone..
I just hate wasting my money on cards that don't seem to work

First of all, since you live in Trinity, it would be nice if you knew how to writer proper sentence to get your question across.
Secondly, why you're spending $30 for an SD card is beyond me.
Third, you need to consider the brand and speed of the SD cards you are supposedly purchasing. Are you buying a brand from a reputable manufacturer and are you buying a card with sufficient speed for WP7? I would recommend at a minimum a Class 4 card (Class 6 highly suggested). Also, a 2GB card probably won't buy you anything on WP7 since WP7 on an HD2 uses the SD card a the primary source of working memory. Thus, at a bare minimum a 4GB card is recommended.
And as most of the posting on the forum have indicated, the SD card issue on the HD2 is a hit and miss affair. And I really do hope you have the SD card in the phone when you install WP7, otherwise, no amount of changing will work.

i would highly NOT recomend a class 6 card, there is less chance of that working.
The class ratings define sustained sequential speed, WP7 doesnt need that, it needs high random speeds, the two are not always compatible, go for a class 2 or 4 card and you are more LIKELY to get a card that works, as teh above poster mentioned, it is hit or miss and there is no compatible list, there is apparently a AT&T card branded for WP7, good luck finding a place that sells that outside of an actual shop and expect to pay a premium for it.

Yes I have installed WP7 with the SD card in. First with the 2g card that came with my HD2, then with a Scandisk 4g one, and then with a $30 Kingston 16g one.
Honestly, im going to radioshack tomorrow and going to buy a 4g kingston class 4 one. In the sd card forum it says it works. So we will see.

did you honestly read those threads? there isnt any 100% compatible cards, all these, "confirmed working cards" threads are about as confirmed as the paper its been wrote on. Buy what you can afford, because the only way you are getting a "confirmed" card is if someone has actually tried it and has given it to you. Also its worth noting that getting it installed on the card is only half the battle, if WP7 has the slightest issue with thecard it it can course several different issues.
As i said, its very much luck if you can get it working, it absolutely flys and is super smooth if you can get it perfect

[Q] SD cards suddenly not working

Hi. I bought my Note 3 last year in October and I used my 16GB class 4 SanDisk card. It worked perfectly, it's just that it was pretty slow when saving 1080p/4K videos.
So I decided to buy a 64GB class 10 SanDisk card from Amazon. But I had many problems with the card, images and videos were corrupted etc. Though when trying the card in other devices it worked fine. Also tested it in my computer with software that filled the card with 64GB of data to verify that it was 64GB. I also manually filled the card with 64GB of images and videos and nothing was corrupt.
So I decided to just use the phone without an SD card and that is what I have been doing for the last 5 months.
Now I wanted to use my 16GB card again but it isn't detected at all. I have tried three different cards but nothing happens. I have tried everything I can think of, factory reset amongst other things.
I'm using stock rom and it isn't rooted. Do you have an idea what could be the problem? Perhaps it's simply faulty somehow?

The myth is samsung devices works great with Samsung memory cards, and always have issue with other branded cards. I’ve been using many Samsung phones with Samsung cards and never ever had any issues.
The corrupted video files, data errors etc are surely due to the using of SanDisk card. But as its now not detected at all that I cant say. It could be an hardware issue too. But try with another card or few other cards, if its not detecting any of them then it’s a hardware issues.
But if it detect others then try/test any Samsung card before buying or get one I’m sure it will work perfectly.
