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,

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.

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
Hi
Because manaufacturers never give us enough internal stoprage I install most of my applications on my MiniSD card.
This seems to work fine MOST of the time but often if the phone has been off for a while I cannot run applications stored on the MiniSD without soft rebooting.
It seems the phone 'forgets' about the MiniSD card.
Is it just me or do other people suffer this?
Is there a simpler way to restore funtionality than rebooting?
IS THIS A BUG?
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).
Hi guys, anyone else experiencing really slow downloads through the market? I'm talking 10-20kbs which is really annoying when I'm setting up a new rom. The issue seems to be rom independent and what I don't understand is why the market is so slow when my actual data connection is fine. I've ran speedtest and I'm getting 10Mbs connection speeds (over wifi) so it seems strange for the market to have such issues.
Yup, been having that on every rom as well. A temp fix I know is to unmount SD card before starting the download, that should give you good speed again. Not too practical for every update, but a huge timesaver after a fresh install!
This is a ROM issue not the markets slow server ?
It's definitely a problem on our side yes, the market servers are doing just fine.

I agree with this...i also realized that if unmounting SD solve my problem, maybe the sd is the problem...so I treat it out with another sd card...turn out my sd card was going bad...so if unmount SD helps, try another card...good luck

I'll give it a go and see if it's the case, if it is we need to identify what's causing the problem in other builds.
I have the same issue on my hd2 android.
my download speed is about 5-40 kbps...
so what is the difference in this build? maybe the cooker can share it to make all builds perfect

You do realize, don't you, that when you use the "unmount SD card" option in Android, it doesn't actually unmount the SD card?
I've tried that build but I'm seeing no change in market download speeds, I have noticed that wifi speeds are much slower than over 3G though, I'll try this on my current build (MDJ FroYo HD v.4.0) to see if it's a wifi only issue.

Of course I do...but if it helps, it helps...lol
@tung...did you try the unmounting SD method to see if it'll help...
Well, this problem that you guys are experiencing is all because of the SD card. I have tested two cards using the same build, one is the original SanDisk 16gb class 2 and one is the new Samsung 16gb class 2. The Sandisk download app super fast and the Samsung one only get 10-20kb/s. Even the same class, the two card have different write speed. So it is all because of the SD card. Seems like SanDisk would work best.
To explain the "unmount thing", because android systems sync with the SD card all the time and that take up a lot of write speed. If your card does not have a good write speed it would take longer. By "un-mounting" the SD card, you tell it to stop syncing and the speed is much improve. That's all. Warning: if you turn of the phone when unmount, you will experience data loss or corruption.
great way to put things in perspective...that's why I advice OP to try a new SD before blaming it on the BUILD...

i use the same card for all builds that i test and still nexusv1.7 is fastest on market downloads.
I think I can verify the SD card theory. My girlfriend and I both have hd2's running android (same build, rom, radio, hspl). The only thing different about our phones is that I'm running the original sandisk 16gb class 2 and she is running a 4gb PNY class 4 SD card.
Her market downloads, strangely enough, are incredibly slower than mine on the class 2. I had always wondered about that since she had a class 4...but I guess it does make sense. Although the payoff for her is her android boot time is incredibly fast.

With SD unmounted my market also is a little bit faster but still too slow.
(MDJ FROYO HD 4.0 and WLAN).
Any other solution?!
Yeah really very slow
