All my programs are on storage card. I would like some programs frequently used to be always on, e.g. Pocket Informant. However, they keep closing. I cannot confirm when this happens, but probably after screen shut off or much later. Is there a way to keep these programs running?

It may have something to do with how long after awakening before the card is available to the operating system. The solution may be to have a fast card (133-150X). I went from a 1GB card which didn't say how fast it was (1X??!!) and which had this problem, to a 4GB 133X card which generally does NOT have this problem. It occurs occasionally, but generally, if I leave TotalCommander running, it's still running when I open the device and start it the next morning. Hope this helps. Cheers,
gibhenry, Thanks for reply. .At the moment I also use 1 GB card. Want to try 4 GB. Does 4 GB work on Jasjar. Precisely, which one do you use? I wonder, any how, what does the size and speed of card have to do with how long before awakening the card was accessed?

Well, I can tell you to just use a PLAIN SD card, not some of the advanced architectures, which will not work on the Universal. I got my 4GB card in conjunction with my purchase of iGuidance GPS software from buyGPSNow. It is a 133x card. I had purchased a 150X card that's something like SD-CF (but I'm not sure exactly what the designation was, so don't take that literally), and I determined that they will NOT work with FAT32 on either the PC or the PPC. So be sure you get a plain but FAST SD card for your Universal. Hope this helps. Cheers,
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).
I've been watching, reading, and doing my own research on the subject.
Here is my conclusion. Curious to see if you run into the same:
1) There were a bad batch of 16gb class 2 micro sdhc cards that were replaced by T-Mobile.
2) The micro sdhc cards were CLASS 2.
3) On the original stock ROM had \storage card\application data\htc data stored on the card. As of the new ROM, that data is officially stored on the phone memory. I know this because I sync my sdhc card to my home PC using ViceVersa and haven't had a single file in that directory change since the ROM upgrade.
4) I've never had any freeze issues, but that's because I have a 16gb CLASS 6 sdhc card that moved everything to and don't have the speed/reliability issues that others may have experienced because of #1 and #2.
I have no idea what the data is that was being pushed to the card in the old ROM, but I believe that T-Mobile recognized issues with pushing data to a card where it may not get mounted quick enough on boot, has speed issues (class 2), as well as having a possible bad shipment of cards.
I also believe that depending on the above scenario, T-Mobile may have been blindly replacing "bad" cards as a fix when in reality, it was more of an issue with the speed of the card and/or possibly the card not getting mounted quick enough on system boot causing stability issues.
I would challenge anybody with the original ROM to pull their SD cards for 24-48 hours and I bet your freeze issues go away, unless you actually do have a bad SD card.
On that same note, that would explain why a custom ROM would fix the problem, because chef's weren't configuring their ROM's to cache any data to an SD card.
Bottom line, it wouldn't matter if you installed anything to the card or not. Because the original ROM was configured to write to the SD card if it found one, you would "potentially" have freeze issues with a bad or slow card, no matter what.
Sorry if this is redundant, but I've seen everybody making conclusions on bits and pieces of the information, but not with the entire picture I painted. Maybe I'm right, maybe I'm wrong. You decide.
=)
Update:
After finally deleting the \storage card\application data folder, the files did come back. Does anybody know what these are? I'd like to get those to point back to the phone memory personally. I don't like anything on the external card, other then what I say should be there.
I tried searching the forum and I couldn't find anything that really answered my question. I currently have a 2gb Nokia sd card in my HD2. I need more memory, so I got a 8gb Sandisk card. I realize that once I switch out the cards, I will essentially be running a "fresh-from-the-box" version of WP7. My question is: Is there a way for me to move all my existing data (apps, messages, settings, etc.) to the new sd card? I also want to make sure my activation stays intact through this move. Basically I want my phone working exactly as it is now, but with more memory.
Hey xRedRiot!
Did you find a solution for your problem? I´m in the same situation right now, just want to switch from a 4GB to a 8GB card...
it will not work, you will lose everything
as of now there is no backup software to do this, i know, it sucks

Unfortunately I have not found a solution, even though I have been actively searching. If I end up finding out a solution, I'll post it back here for anyone else in the same boat.

If some kind developer could figure out something and make a backup software to accomplish this, I would greatly appreciate that.

So basically you're stopping after step 8 and putting the larger SD card into your HD2, thus having it run exactly the same but with more memory? Just to be clear, when I put in my 8gb SD card, I will end up with about 6gb dedicated to the OS? That's what I'm getting out of the directions in the link and I wanted to make sure I'm understanding that correctly.
I Have HD7 Runing On HD2. My Memory Card Dont work. I Look around the forum and still dont Understand what type of memory card work or maybe there a trick to it.

Thats The Kind Of my memory card.
Brand: PNY
Size: 8Gig
Class: 4
Any help will be appreciated
theres no way of knowing if it works until you try it.
stick to class 2 or 4 cards, sandisk seems to have more luck than others but ultimately its luck, there is no list of working cards, and just because someone has a card that does or doesnt work doesnt mean you will have the same result
it is thought that it needs higher 4k random access speeds but we can be sure as everyone seems to have different results
And when flashing my phone..should memory card be in or out.
