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).

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

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
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'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.
Hi All,
Does anyone else here suffer from continual SD card corruption? It appears that the early superblocks of my card are continually being corrupted by my Hero no matter how I format or partition the card.
Naturally I would assume that this was a card issue but running some load tests on a laptop shows the card to be functioning properly and reliably. Next thought would be that it's the phone but using an alternative card in the phone seems to be trouble free also. Any ideas?
My alternative card is a 2GB vs the troublesome 8GB card that I would prefer to have for music, etc.
I see lots of web results for people complaining about corrupt SD cards but no solutions or responses.
I had this problem too. Fixed by buying a decent class 6 microSD card. No problems since.
My Samsung Galaxy has an out-of-memory problem and stop receiving SMS.
It shown that I used 20% of the 1.87 GB program memory.
1% of my internal SD card memory (16GB), 40% of external SD card (8GB).
BUT I used 116MB/127MB of my Personal Data area, or 92% used.
Is there a way to relocate the Personal Data (e.g. Calendar, address book, etc...) to the internal SD card?
