It *is* possible that the card is in fact defective. However, if it is a Japan labeled Kingston, and you are having issues with it, I'd contact Kingston for a replacement. If it is a Taiwan Kingston, get it replaced with the Japan version as well. Kingston pays for shipping both ways. So, there's really no excuse to be *****ing about your non-working card when Kingston is only a phone call away; and they WILL fix it!

HTC just released a fix for the Artemis for SD card issues. Maybe they'll post a fix for the Hermes soon.

The Kingston is Japan, the SD is Tiawan. All my cards work fine in my Dash and Samsung devices. None of my cards work well with the 8525. I usually have to reset every other day or so. My current registry settings lasts about a week.

PNPWaitIODelay always resets to the same value as PNPUnloadDelay. So I have set PNPUnLoadDelay to 10000 to have the PNPWaitIODelay "inherit" this value.

The ROM I'm using is the official HTC AKU3.3.1 WWE released by Leaf, South Africa.

Can anyone confirm that Japan made 2GB Kingston cards exist? I called Kingston today to get them to swap mine and they claimed that they don't have any 2GB cards made in Japan, and that they don't support anything higher than 1GB on the TyTN
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chenga:
You know, that's a good question. I've called in trying to exchange my 2GB card several times, but they tell me that they only have the Taiwan cards in stock and that they have no ETA for more stock of the 2GB Japan cards. I never did ask if Japan 2GB cards actually exist...
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Ender666666:
I do know that I was having my Japanese made, 1GB Kingston card disappear every couple days... Even with all the suggested tweaks enabled. Granted it was less frequent than I seem to recall with my Taiwanese 2GB Corsair chip, but that isn't scientifically accurate. I'm testing a Taiwanese 2GB Kingston chip at the moment. Will post results if anything interesting happens.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chenga:
I find that my 2GB Kingston (Taiwan) card is more stable than my 2GB SanDisk (Taiwan) card. I actually haven't had a disappearance yet [2 weeks](knock on wood).
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] jnmarshall:
I called them, twice, also about my issue. They DO have cards made in Japan, I have one, and suspect it may be defective now. The first person I spoke with pointed out that the 2GB cards are NOT supported in HTC devices. Walked me thru their website to that fact. And would not warrantee it unless it fails in a "supported" device.

The second person was willing to swap the card out, but can not guaranty where it was made, it's just what they have in inventory.

Looks like the days of 2GB are over for this thing.

The fix is for the Tytn (Hermes) and Atermis, I have had no storage card problems so I have not tried it. I have attatched the cab file below.

Can people with storage card problems report back on whether it works or not please. :)

I have had ongoing but occasional problems with my Kingston 1GB (Japan) card. I don't see any corruption, but I regularly do a Pocket Mechanic scan and it finds lost clusters, etc. Also occasionally lose my MSMETADATA file (even with WM6) -- probably related.

I have downloaded and installed the patch and will monitor for a week or so. Will post again with the good or bad news.

[8525, TyTN, MDA Vario II, JasJam Software Upgradin] johnburn:
Back to the drawing board, HTC!

Well, I didn't have to wait long -- less than a full day in fact. Last night when I launched Newsbreak 2.0, an "Unexpected error" occurred (aren't all errors unexpected?) and all of my subscribed feeds were gone. Closed Newsbreak and launched Pocket Mechanic and did a "Scan" of my SD card. It found all kinds of corruption such as lost clusters and cross-linked files, much worse than I have ever seen before. I had to recreate all of my feeds and Newsbreak prefs from scratch. Luckily I still had an .opml backup from the last time I did a hard reset, so it didn't take too long.

I have removed the "fix" from my device and will wait for the next attempt from HTC. BTW, an HTC engineer told Leaf Wireless in South Africa that they (HTC) believed that this corruption was being caused by a hardware defect on the original motherboards used until mid-2006 or so. If this is the case, I can see that they would want to try to find a fix in software, as a hardware swapout is an extremely expensive undertaking. However, there is a good chance they won't be successful (at least, not for everyone).

That KB Article is marked as not-applicable to Windows Mobile (only Windows Embedded CE) Storage Management.

I wonder if we're affecting anything at all when we change these values.

For the record, I have the problem with a Cingular 8525, running the WM5.1 upgrade ROM 2.15.502.3. It occurs with both the SanDisk 2GB microSD and also a Kensington 2GB (mfg in Taiwan) card. Too late I noticed the post about the 2GB Kensington not being supported on HTC, so I guess I'm on my own for support.

I've downloaded the HTC card driver update for the TyTyn and we'll see what it does with these.

Dan,

I did the reg hack and it 'appears' to have worked as I have now had 6 days without problem - I'll report back.

Did you know that it can take some minutes before any changes you make to the registry actually get committted to stay there? I have read that it you press and hold the power button to turn off the device (rather than soft-resetting) that this commits the change. Better perhaps to waiat a while if you are in no rush.

Give a go and see then if the changes stay. Hope this helps :)

At the risk of cross-posting, I had two 8525s, 1 Cingular branded and the other AT&T branded. In the 3 weeks I had them, I wasn't able to go more than about 12 hours on either of them without a soft reset (had a SanDisk 2GB card). Last Friday I picked up a 2GB Kensington card made in Japan. Plugged it in Saturday morning and went TWO FULL DAYS without a soft reset. I finally reset because I needed to uninstall/reinstall some software and haven't reset since.

SanDisk 2GB

For what it's worth - since upgrading to WM6 (Black MAJIK then SATIN) I hacve not seen one single error or experienced one single problem worth my Micro SD card. Could of course be luck - but I doubt it. The same card was giving me no end of problems with corruption to files and then whole folders going missing.

The reg tweak suggested did also resolve the problems (for 5 weeks) but I then upgraded to WM6. Lots of others are reporting similar stability after move to WM6 - does anyone still have SD card problems after an OS upgrade?

try disable power managment

one you can just disable sleep and the storage card should not have issues.

two there is a reg setting to disable power management for the sd card.

i had this set for my wm5 build.

hklm\drivers\sdcard\class\sdmemory

DisablePowerManagement 1

solved my issues for wm5.

then i jumped through the hoops to install sleuths 3.1 wm6 build.

the registry setting was already in place on sleuths build. i figured you all must have known the fix and added it yourself.

the key isnt there in wm5 you have to add it.

it is in by default in sleuths wm6 build (you all totally rock at this. smoothest hack install ever)

from what i can tell this has 0 effect on battery life.this weekend my phone with an extended battery was off power for about 40 hours or more.

with wm6 my phone is almost useful as more than a phone.

i installed spd mobileshell, pocket plus,diary, time, and maybe voice command 6.1 on the sdcard in wm6. very few issus and no lock ups. i havent had my phone lock coming out of sleep since i made the change

YMMV

Hi,

I've been reading this thread since last month. I got myself an Orange SPVM3100 and it had an old rom installed, so I upgraded to the latest official orange rom and then bought a 2GB micro sd card, of "AMCO". I think its a Korean company. Anyway I didn't notice any problem, soon I upgraded to official WM6 HTC tytn rom, and made a quick jump to Schaps 4.31, and then the problems started. My apps installed on the card started disappearing. File explorer started to show empty folders Sometimes my tytn had to be soft reset, as I couldn't wake it up out of standby by using the power button etc, you all know the usual problems. I explored my registry after reading this thread, but my values, (as it was a cooked ROM) were already on 8196. I tried the tweak of having nothing in "my documents" option. Formatted the card to fat32, and every other tweak mentioned here, then I went and got a Kingston card with JAPAN written on it, later a SANDISK card and then even a KINGSTON card with Taiwan written on it!!!! but nothing worked. So I decided to reflash to the official orange ROM. Well it has been three days, and I've haven't had a single issue with my SD card. The phone comes out of standby in normal manner, no lagging in file browser, in any. And I've been heavily using the card, like placing 400 mb of music and videos, installing dictionary and encyclopedia, which alone take a GB. And syncing with my pc for contacts and emails. So IMHO its a ROM issue. At least thats for me !

Wise Fix for WM SD Driver Stack (vs. no SD suspend)

I like this workaround of not suspending the SDcard but it uses more battery than intended. Knowing that this problem apears accross the board on many non HTC WM phones... it seems it is caused by a generic WM implementation problem.

Okay all above information in the forum points to a genuine timing issue, specialy evident when resuming. Even MS engineers acknowledged this with an official workaround: \StorgeMgr\PnPDelay settings that sometimes help, sometimes not based on the phone and make/model of SD card in use. (see earlier posts about Taiwan vs. Japan)

So what is the core of this problem: Windows "PlugNPray" runing through a laundry list of enumerations!:mad:

The rational: enumarate SD early so we don't depend on other drivers hanging before we get to it.

How to fix this once and for all: load the SD driver stack earlier, tweak priorities and bump up timeouts. (Based on a Hermes 8525 PDAVietV2x)

HKLM\Drivers\BuiltIn\SDBusdriver\Order=3

HKLM\Drivers\BuiltIn\SDHC\Order=4

HKLM\Drivers\BuiltIn\SDHC\CardDetect_Thread_Priority<109

HKLM\Drivers\BuiltIn\SDHC\PollingTimeout=384 (0x180)

(The evidence shows that the SD stack was only involved way near the bottom after too many high level protocol drivers and such.)

While we are at it let us make the SDCard content safer with this entries:

HKLM\System\StorageManager\Profiles\SDMemory\FATFS\DisableAutoScan=0

HKLM\System\StorageManager\Profiles\SDMemory\FATFS\EnableCache=0

There are some settings available for auto formating SDcards but I guess no one has really used AutoFormat since WM SD implementation has proved to be half-baked. :(

To test my tweaks I am runing with PnPUnloadDelay and PnPWaitIoDelay set low (1.5s) at 1500/1500 on a 2Gb LG card.

SanFrenchysco.

[8525, TyTN, MDA Vario II, JasJam Software Upgradin] sanfrenchysco:
What do you have under HKLM\Drivers\BuiltIn\SDHC\ ?

What ROM build are you on?

.. perhaps your build has an older/newer SD driver

On top of what I have posted above I am testing disabling *Disk* caching for SD as I suspect there may be some internal wear-leveling logic involved with some SD cards that can invalidate FAT cache content.

That could explains why problems only happen overnight and on some models and not others...
