Hi everyone.
Hope someone can shed some light on this, I have a Kingston 512MB SD card for my XDA2, contained on the card are maps for TomTom Nav2, MP3's and a couple of movies.
I have not done a HR in a few weeks and only a few SR's, yesterday I wanted to navigate and use TT and all the data on the card had disappeared. Has anyone experienced this b 4? Any help would be mush appreciated.

Dissapearing data from SD card.
Hi,
I had this before on a 256MB card with maps on it. I reinstalled the maps and then hardware locked the card only moving opening this up on the occasion I need to move stuff to it. Mine wiped right when I needed the navigation system so I always keep it locked down now. I know it's not an answer but it saves a long and slow re-install.

I'm also getting my 256MB SD Card(PNY) erased/corrupted, sometimes I have multiple entries for my storage card! This always results in losing everything on the SD. I've tried all the romkitchen versions of 2003 and get the same results. Plus I've noticed running the SD-Backup appears slower, taking 1h 10mins for 12MB. Someone must have a clue whats causing this.
XDA I (Wallaby)
32MB RAM
OS ROM 4.01.16
Radio 4.21.00
SD data disappearing
I have experienced the same problem on XDaII and completely lost the data.This despite a back up I lost many holiday pics and movies.
Q I use "Pocket Explorer" to move jpg & video files onto the SD, they appear to be there but then they dissappear. Any thoughts or suggestions would be appreciated.
never had that happen on my 2 sd cards both sandisk and 1 128 and the other 256
I was just playing around with my device the other day and saw that when I removed my miniSD card my available memory increased.
Pre-soft reset
- with card = 13.3Mb memory
- without card = 17.4Mb memory
Post-soft reset
- with card = 20.6Mb memory
- without card = 24.9Mb memory
I use a 2Gb Sandisk card and dont run anything from it just store backups and TomTom maps.
Is it normal to see a 20% drop in available memory with a miniSD card installed?
I haven't tested this on my MDA as 90% of my stuff is installed on the MiniSD card so taking it out might lead to a load of problems, but it makes sense to me.
If i remember correctly WM5 (Windows Mobile 5) caches some of the FS (File System) data to RAM (Random Access Memory) to decrease access time. If my memory is accurate than the freeing up of memory that you see occuring when you remove the card is simply that cache being flushed as it is no longer needed (the card is removed).
I have the T-Mobile (USA) MDA, an HTC Wizard. In it I have a Sandisk 2GB miniSD card.
For the second time now, suddenly and inexplicably, most of the data on the card is missing. There was no operation I executed that could have deleted the data, it was suddenly gone, for no apparent reason. This happened once before?
Has this happened to others? Is it a bug in the MDA, that it sometimes deletes data from the storage card, for no reason? Are those miniSD cards inherently unstable, sometimes suddenly losing their data? Or might I have a defective card?
If the card is defective, I think I could call Sandisk, and get a new card under warranty. (If the MDA is defective, nothing I can do about it, no longer under warranty.) So, I'd like to have some idea--bad card or bad MDA?
Also, I have a USB card reader that can read miniSD cards, and have used that before to transfer data to the card from the computer. That seems to no longer work. I wonder if that is also an indication of a bad card. (Although it could also be the a failure of the card reader, or of my Windows XP installation.) Now I can only transfer data back to the card via ActiveSync.
Is there a utility, that either from the computer, or directly on the PPC, can check the disk surface of an SD card for errors, and fix them (similar to chkdsk)?
Any insight into this problem would be appreciated. Thank you.
I assume you checked the SD on a computer to verify the files were actually gone, and not just "hidden" from the MDA?
Do you have another chip you can test run? Maybe in a camera or something?

"Hidden from the MDA" in what way? (Even when files are deleted they are not "actually gone", and can sometimes be recovered.) Do you mean turned into "hidden files"? No, that's not the case, as I have Resco Explorer set to view all hidden and system files, not to hide any files, and it didn't see the files, nor did any app. Nor did ActiveSync, when connected to the computer, Explore.
As I mentioned, my USB miniSD card reader doesn't seem to be functioning either, so I cannot look at the card directly on the computer.
I'm not sure what you mean by "test run another chip"? I do have another miniSD card, a 1GB card I had purchased first. I don't see what point would be served by "testing" that. It is not that this card is constantly deleting files. You could test this card, and it would seem to be OK. But it has happened twice already, that most (not all) of the data on the card was suddenly missing. So, there is definitely a problem, either on the card, the MDA hardware, or an app or the OS (WM5) on the MDA. But you cannot test it out by putting in another card, as one wouldn't necessarily see the same problem right away, as one also might not with this (problem) card.
Something strange happened since the original post though. Fortunately, I had a lot of the data from the storage card backed up to my PC. Via Activesync, I copied some of that back to the MDA Storage Card. After doing so, suddenly it looks like all the missing data has been restored, including a lot of data that I had not yet copied back.
What could have happened? Still wondering whether to call Sandisk and report a defective card.

That isn't the question. I didn't ask how to undelete the files. And, as I said, my card reader isn't working either.
Also, as I said, I had the data backed up to HD, so really don't need to undelete.
So----what's the problem then? Obviously something's wrong if a memory card suddenly and inexplicably loses its data, now for the second time.
So I was asking--what could be causing this to happen? Has it happened to others? Is it likely a defective card? Or defective PPC?

Yes, but without an alternate means of testing either, it's a waste of time to speculate. Hence my admonishment to go find a card reader. You can run a complete format and look for bad sectors on the suspect SD chip that way...something you cannot do from the PPC to the best of my knowledge. Chances are, the boot sector (where the location of files in memory is written) on your SD chip is failing (if the chip is old, that is VERY likely, as flash memory has a limited number of rewrites that usually hits around the 2 year mark for heavy users, and if you're moving music on-and-off a lot, that's you....).
So, no, there's no way to be SURE, without getting your hands on a reader (and c'mon, they're like, $10).
Hey Guys,
I've been having a TON of problems with my storage card lately. I was using doubletwist to sync music when the problems first happened. Basically the storage card flipped out, it wouldnt allow any access either through the computer or on the phone. So i turned off the phone popped the Storage Card out and then back in. When I plugged my HD2 back into the computer i discovered that all my files on the storage card had been deleted.
I called t-mobile customer care and they told me to call the htc accessories line to get a new one. Did that and the lady says theres nothing they can do as all the cards are back ordered.
I'm worried that its going to happen again, and on top of all this my 16 GB Storage card is now 971 MB, i was adding my applications when it said the card was full so i checked and thats what the computers giving me.
I figured that maybe if i formatted the card it would work but i cant find that option anywhere when i right click on the card when plugged into the computer.
So basically all i have now is a 971 MB Sd card with a few applications on it instead of the 16 GB preloaded SD card that held about 200 pictures taken with the phones camera(that are now gone along with Transformers and everything else that was on the phone)
Sorry for the long rant guys but im really frustrated...
Any Help?
Have you connected the phone to the PC in 'disk drive' mode? If not, then do that to 1) be absolutely sure you can't see/recover any of the files, and then 2) to format it (it has to be connected this way for that option to be available)
I'm not an expert on here (more of a "user" than a "maker") but I have had my share of SD card problems.
If you are using the class 2 card that came with your phone, order a class 4 or class 6. The class 2's are known to cause performance problems for the HD2. When I upgraded to my class 6, I noticed the difference right away on graphics-heavy apps that use the SD card in realtime (i.e. not just to store profiles).
You need to decide if you simply want to get your SD card back or try and save data on it first. If you just want to format it and start over, try these:
Try first using the sd formatter in your HD2, in the "Tools" folder.
If you have a card reader or a card slot in your Windows PC, try inserting the card (or, as sirphunkee said, mount your HD2 as "disk drive" and not as active sync) and go to control panel > administrative tools > computer management > Disk Management and see if Windows can read your card. If it can, you should be able to right click on the drive and select "format". You could also try assigning it a new drive letter. Sometimes it seems to kick start the Drive Management services into accessing your card with a proper mount.
Download SD Formatter from Panasonic. Sometimes when windows can't do it, this program can.
If you have an uBuntu OS installed, sometimes using gParted is also effective.
I have also seen threads on here about downloading the default factory files that should already be on the card, with links...
Hope this helps. But bottom line you should definitely NOT wait for another crappy class 2 card from TMo/HTC and go get a class 6 (you can find them easily enough online for about $50).

So instead of using active sync to connect use disk drive mode. Got it, but once i do that if there were files to recover i would see them correct?

Yes, as long as you're looking at the card's contents via file explorer on the pc, not the phone...the one one the phone won't be able to see the card at all when it's connected that way.
Basically, when you connect in disk drive mode, the pc handles the card just like a regular external USB hard drive.
You'll probably be able to format and use it again now that you're connecting it that way, but if it still acts up then go through any and all of mfrey's steps above, including just upgrading to a higher-class card if possible. The stock cards that come with the HD2 seem to be somewhat inconsistent in quality and potentially unreliable, and as he said the speed difference of a faster card can definitely be noticible in every day use.
i connected the phone via disk drive mode as suggested but i had the same results after connecting multiple times so i decided to format the card through the phone as mfrey suggested. After doing so the card still reads as a total of 971 MB both on the phone when checked under settings and on the computer.
Im going to try going to t-mobile to see what they say about my problem because i dont see how this could happen, ive been using this sd card for about three months and up til a few days ago it worked perfectly
Wish me luck guys

Were you able to see the drive in Drive Management in Administrative Tools? If so, when you right-clicked it, was there an option to delete partition? Did you try SD Formatter (it's free)?
If it's the factory class 2 that came with your phone, it could be bricked...
Hello all,
Used to be on here for about 10 years but now I don't have access to my old email so I'm back to being a newbie. I feel like one too since the last device I rooted was a HTC HD2. Those were the days... LOL I've been a longtime Windows guy since 6.1 and before and have followed the progress through 7, 8, 8.1 & 10 as an insider but I think it's time to start looking at Android again.
Anyway, saw this really great deal on Amazon for the Idol 5S and since I was already using an Idol 4S with Windows, I thought I'd give it a go. Especially for $211 it seemed like a pretty good deal to me. Now the first annoying thing is really why the price was so good and that's the Amazon Prime ads on the lock screen. No way to get rid of them. They've obviously rooted the phone already and taken away any developer options and that's what I was looking for when it brought me back to XDA.
My problem is that I have an SD card installed, I made sure to format it and it functions as you'd expect with one exception. When I connect to my PC via PTP (Win10 latest insider build), I see internal storage but not the SD card. If I change to MTP use for the USB, I get nothing at all just a charge. I've installed the correct drivers in Windows so I don't see why this should be an issue unless something has changed these days with you having no external access to the SD card? I was thinking of checking USB debug mode to make sure that was off but like I said, no developer options are available.
That brings me to my question (Dumb or not), anyone got any ideas? Is my new newbie status just making me blind? I guess there is no way to root this device yet until some clever dev comes up with a way but if anyone has any suggestions, I'm all ears. thanks in advance and have a great day! :good:
There are no dumb questions (as long as there are no sticky threads that already contain the answer ).
Are you using the SD card as an external storage or is it recognized by your phone as part of the internal storage (c.f. settings->storage)? The latter is an optional feature that got introduced with android M. Neither your phone nor your PC will distinguish between the phones internal storage and the SD card if you use this option.
You need to be aware that your SD card gets encrypted if you decide to use that feature and that only your phone is able to decrypt the data that is stored on the card. In other words if your phone dies due to whichever reason then you won't be able to recover the data on your card. In addition, the internal storage of nowadays smartphones is quite fast (in regard to its read/write speed). Most of the SD cards on the market aren't (in comparison to the internal storage's speed). This means that integrating an SD card to your internal storage slows your phone down.

Thanks for the reply Flippy. I've tried to format the SD both ways. First as external storage and secondly as internal storage. Either way I do it, it is not showing up in Windows file explorer as expected. I see internal storage being the actual phone with no problem but no go on the SD card. It's a strange problem that I've never run across before. I've read that this may occur if USB debugging is on but since this is a pre-rooted phone by Amazon, I am unable to confirm if this is the case or not since there are no developer options or ways to get to USB debugging. They are omitted from the settings menu. I guess you get what you pay for buying from Amazon but I will hold out hope that the price and build quality will make this phone popular and some clever dev will find a way to root it so I can flash it with a new build without the limitations.
With regard to the build, it's very nice. All aluminum bezel, beautiful design. Responsive and snappy and a perfect form factor with it's size. I like it so far but I would say that I am looking forward to making it my own...
Thanks again for your response.

I'm wondering if this phone will be rootable? Seems Google is making it harder with Nougat.
