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.

memory problem

Hello I have had a look at the wiki and still could not find the answer to my problem, so I decided to post.
I seem to be having trouble with my new Memory card for my TyTn. I just bought a 4gb microSDHC from the shop. I put a single song on it and put it in my phone. When I checked the memory it says this:
“Total storage card memory: Not installed”
Does this mean there is something wrong with the card or do I need to install something.
Cheers

Are you running a wm6 rom? high capacity sd is not supported on a stock tytn. Check the Windows Mobile 6 forum and look for a cooked rom that supports SDHC. I recommend the schaps 3.60a cooked rom. Been runnin it for a couple weeks now and im pleased with the speed/stability.

Thanks for your response Surrept, I have installed the schaps 3.60a-0823_full and the phone looks great now…but I still have the same problem with the memory, any other suggestions?

Umm, should I take the memory card back to the shop, and if so what is the best one that will work with my phone?

Can anyone help please

Last thing to try:
Reformat the card using the PC Fat 16 or 32
Check size shown on PC is correct.
Try again on your Hermes.
If it does not show up, reset with the card in place.
Try again.
If it fails again - do a hard reset with the card in place.
If all that fails, then return to the shop. There is no more you can do. Since the card is not faulty, you will be a bit at their mercy. It will be a gamble to get another 4gb card, a 2 may be safer. However if it's the contacts in the phone then no card will work correctly.

Thanks!
My friend had a look at the phone and said he had no idea what to do, he handed it back and the card just started working! Wow! Is it great how that works some times.

Help! Memory card undetectable!

Very confused, I minute I was listening to music and the next minute my memory card became unreadable. I have resetted the phone several times and have taken the memory card out and reinserted it and still it will not read that card and when booting as majority of my programs is on the card error messages on boot gallore. Also tried my sd card on my friends HTC and also same problem.
Any way to fix this problem as it still shows that the SD card has 1gig of information on it but it cannot see.
Hope someone can shed some light on this. THanks

USB?
I understand that it's highly unlikely ..........But, you're not connected via the usb cable to a PC are you? this will hide the starage card (unless by activesync)

Nope not connected to anything.. In Fact when I connect it to the computer, the computer won't recognize it either ..

Simply read these threads. Not that it will fix your card, but it will help you accept you simply need to buy a new one (given that you claim your PC also does not recognize it)

Personally, I consider myself lucky that it is the card that broke, not the phone.

Check out the StorageTools app mentioned in the Thread above.
This has a verify option for SD cards. I used it on my 16gig card when it started behaving strange (due to some weird app I used and terminated).
Later I used the format option to fix the card - worked fine !!

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!!

[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
