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.

MDA Storage Card Woes...

I've had a T-mobile MDA (USA) for about a month now, and I really enjoy it! But, starting a few days ago, I've been having a lot of trouble with the MiniSD flash memory cards. The first card I had was a Corsair 2GB minisd, it worked fine for about a month, then it mysteriously stopped working a few days ago. I decided to RMA the card, but while I waited for my new one to arrive, I would purchase a cheap 1GB minisd so I could at least have some of my data and programs.
The second miniSd (this one branded with the name of the store I got it from: 'Micro Center') lasted for the past two days. I noticed it was dead this morning.
Here are the symptoms in both cases:
-SD card disappears from device.
-Soft-reset / Hard-reset to find that device wants to format SD card b/c it is unreadable.
-Format SD card, only to find that it disappears from the device once more
-MDA no longer responds to SD card.
For Corsair 2GB MiniSD:
-Attempt to format SD card using desktop PC, which leaves the card with half of it's total memory available (1GB). This is also not readable on the MDA device.
I'm very distraught by this whole incident - is it possible that there is something wrong with my MDA? Or is there a possibility that the programs and data I'm storing on the MiniSD are somehow corrupting it?
There's a T-mobile store near my office, I'm thinking about heading over there on my break to ask about this... but I'm afraid I wont get anywhere with them...
If anyone has any thoughts, suggestions, etc... please let me know!
Thanks

I have issues with my SD card. Quite infrequently the SD card disapears - which is pretty annoying. In my case simply ejecting it and reseating it seems to fix the problem. Occaisonally it becomes a little more problematic.
I think it is a problem with the SD socket on the Wizard, as a friend of mine has the same problem.

HTC Touch not recognizing storage cards

I have been using my HTC Touch for almost a year. I have 2 storage cards, a 1GB and a 2GB. The other day I noticed missing software while using my Touch and found out the phone did not recognize the 2GB storage card (which has all my backup info on it). I assumed this was a card error and installed the 1GB card which also has all my backup stuff on it.
Neither card shows up in the File Explorer and the files on the cards are not accessible. When I put these cards in my computer they are totally readable.
Is this a known issue? Any clues on how to solve it?

i had the exact same issue and returned my device (elfin), in a month later got replaced (some parts) back. it was defenitly hadrware failure in my case.

I've seen at least two similar problems get resolved by formatting the storage card. Strangely though....both those devices were HTC ones. If your computer is reading the card, copy all the info onto it including your backup file and then try giving the format a shot. If it works for you.

Storage Card not recognized
I have happily been using HTC touch w/8 gb storage card, then today storage card was not showing up, did soft reset and it was there again but lost 2 programs and had to reinstall.

HTC is a mess
I was able to get my card recognized again by doing a reformat of the card. My review of the HTC Touch would be a failing grade, I'm afraid. Within the next 3 months I expect to buy out my contract and get an iPhone. The hardware plugin on my HTC is failing again (2nd time). I'm sure they'll offer me another replacement phone, which will once again require me to reinstall all my software, etc etc. I've never seen anything quite as incompetent as this phone. I saw another guy with one the other day and asked him, "How do you like your phone?" So he says it's been great. Works good. Then he adds that this is the SECOND one, since they had to replace his original. LOL I guess HTC and Windows Mobile have set a new standard for cell phones. It can still be a "great" phone, even though you need to replace it eveey year with a new one.

Sandisk 16GB broken

This is now my 3rd micro sd card that stops working.
In one year 3 cards stopped working 1 with blackstone and 2 with Leo.
What is wrong with this type of cards. Is it normal that they break so often????
Any tools you recommend to let them go live again (the card is totally unrecognized by the LEO)
Now I put the microSD card with adapter on computer, and it reads it but is very very slow. Any software tool recommended?
p.s. trying now to scan/fix/reformat and so on

many users are reporting that hd2 are corrupting memory card. mine too was corrupted. the problem is with hd2 itself. i was using sandisk 8gb in xperia x1 for 3 years without having any problem. my card lasted only 1 week in the hd2

it most definatley seems to be a problem, in which the HD2 is making memory cards dead. Regardless of their Size, Class and Brand

any user got this problem from other brand than sandisk?

yeah, am having the same problem here. when i try to copy data onto the card from my PC, it takes ages and then when i pop it into my HD2, it doesnt read the files. i have formatted the card over and over again. i have just purchased another 16gb card. i will let you know if i encounter the same problem again.

I haven't suffered a card failure in my HD2 yet but have with other phones and iPAQs. SanDisk and Lexar replaced the cards in question but didn't say what had happened to them.
I have had success recovering cards with Rescue Disk Pro but most failures like this cannot be fixed.

Ive been using the Sandisk 16gb mobile ultra class 4 card on my Leo and its been perfect since i bought it, fast and realible. Works just as well on my HD 1.

mine 16gb works like a charm.
p.s. flash cards tend to get corrupted if you dont use "eject" feature. at least sometimes it had happend that, not "ejecting" the usb flash, would result in complete data loss./

You are completely right, ive had a couple of incidents with my HTC HD and HTC HERO, where by altering the data of the sd card while it was out of the phone, it would corrup the information on the device, and not let me install any new programs, hard reset :S andd on my Hero constant safe mode :S
Anywho, Flunik is correct it would be much safer to eject safely from the computer, before, it might just save ou those sd cards.

I noticed that my card wouldn't work properly when it was formatted on a PC!
If I let the Leo format the card it runs fine!!

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.

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!
