SD Memory Card

here is just a quick question but is there a program that you can use to format the micro SD memory card built in to windows mobile 6 or 6.1

Storage Tools 2.2 and Resco Explorer 2008, has it. Try it.. :)

thank you
going to try it now

one other quick question what is the largest micro sd memory card the hermes can handle with WM6.1

[shortyboy]

WM6.1 can support upto 32GB,i currently have a an 8GB and it works perfectly...

Yeah, but it's SDHC. Currently I have some problems with my 4GB MicroSDHC Class 4 Kingston. It doesn't start every time, when I turn my device on (I mean, from stand by), so some filders are shown in Resco Explorer, but they appear empty. No problem is shown, when that happens and I can save other files, and that often means I'll have problems again. Also, Resco can't format my SDHC card, but has no problems with my old SD card. Anyone has some simmilar problems?

P.S. I'm useing PDACorner V21.

This is exactly the reason I am seriously wondering where all these guys keep thinking we have an SDHC compatible device. Everything you read, our devices have an SD reader/writer in it, but NOTHING shows SDHC.

There are couple WM6.1 registry Timeout tweaks you can try to get the storage card to stop showing flaky folders content upon resuming.

Take a look at the Performance branch in Schap's AdvConfig tool: there are 2 TimeOut entries showing 1500 - I have mine bumped to 3000 already: the content of my storage card is more consistent but not 100% always as expected. I am still tweaking this timing issue.

Basically the problem is it will show the folder but no file content upon resuming on PDAViet V21 with a 2GB SD StorageCard. When that happens the phone won't ring either, likely because the phone can not read the ringtone file.

To narrow things down, I believe this problem has to do with one of the followings: the StorageManager, the file system or file caching.

My approach is to read the MSDN+TechNet while turning the knobs under the following registry keys:

HKLM\system\StorageManager\FATFS: (FileSystem based on a FileAllocationTable)
CacheSize: 1024K > 512K...Smaller cache
DataCacheSize: 512K > 256K...Smaller FATcache
FATCacheSize: 512K > 256K...Smaller cache
Paging: 1 > 0 (no difference) >1 back to normal.
EnableCache: 1 > 0...No caching!

HKLM\system\StorageManager\Filters\fsreplxfilt:
ReplStoreDoImmaculate: 0 >1 (slows down boot but clears stalled cache content)
ReplStoreCacheSize: 8192 sectors


At this point, I am still not exactly clear on the relationship between the FS Replication and Caching of the FAT FileSystem or what the Replication is supposed to achieve...but I am confident the answer lays in these keys.

My current assumptions: in PDAViet and other ROMs Data are compressed and stored on the FS so you want to cache the useable uncompressed data but Not directly the raw FS content. [limitation of WM6]

Has anybody pined down this FS issue on WM6.1 with Compressed ROM?

I've also got an 8Gb class 4 sdhc: NO PROBLEMO!

Watch which ROM you have.

I've got the Schaps and it works OK

The only times I can find in the power management in Schap's Advanced Configuration Tool 3.0 are 15 sec (that's 15000ms).
Registry values will be usefull, so I can put them in Provisioning XML and edit them autoatically at Hard-Reset/ROM Change.

I think 1500(ms) means 1.5s as found under:
HKLM\System\StorageManager:
PNPUnloadDelay=1500
PNPWaitIODelay=1500
However the FS issue does not seem to be related to this setting as greater delays don't help. I went all the way to 3s and down to 1s with soft resets each time.

Other interesting key to relax the driver timings:
HKLM\Drivers\BuiltIn\SDHC: PollingTimeOut=256 >384?

List of Active drivers:
HKEY_LOCAL_MACHINE\Drivers\Active

As far as I can see the whole branch "\Storage Card\..." does not disapears, only some of the content files are not showing.


On a different note, I can confirm WM6.1 registry is intended to support HighCapacity SD (SDHC) using FAT32 format because of FAT16 size limitation:
HKLM\Drivers\SDCARD\ClientDrivers\Class\SDMemory_C lass\High_Capacity
I am only using a LowCapacity SD (2GB) at this point.
------------------------------------
Update:
I bet the farm SD problems are related to ENCryption issues in some ROM releases. The easy fix is to move to a known good ROM!

If you need to further test your ROM, roll up your sleeves and do:
- (After completing initial ROM install)
- Add "EncryptByDefault"=0 under all found ENCFilt entries
- Restart PPC
- Eject SD card, do a full format on a PC, transfer back your files
- Then report back your test experience

FYI: once you have fixed your SD card beware that your ROM strain is likely unstable and slower than it should be.
The second incarnation of this ENCFilt issue affects the internal storage that gets encrypted during install.

This can ONLY be fixed in the kitchen by both of these settings combined:
1- Defaulting FS encryption to nop:
[HKLM\System\StorageManager\Filters\ENCFilt] "EncryptByDefault"=0.

2- Having a clean blank:
[HKLM\System\StorageManager\FATFS\Filters\ENCFilt]
Move settings under this key back to Filter definition so ENC is not re-enabled by policy.

Should look like this:

[HKEY_LOCAL_MACHINE\System\StorageManager\Filters\E NCFilt]
"DeviceGUID"=hex:\
b4,96,85,ec,70,5a,46,01,ed,ad,64,ae,a7,b9,72,4f
"PolicyDLL"="DeviceEncryptionPolicy.dll"
"EncryptByDefault"=dword:00000000
"Dll"="mencfilt.dll"

[HKEY_LOCAL_MACHINE\System\StorageManager\FATFS\Fil ters\ENCFilt]


Needless to say if you don't enjoy these problems, do not enable FS encryption from the ControlPanel UI. WinCE filesystem encryption is neither data nor performance friendly.

You can do it for pocket mechanic aswell
