I had this problem today. Lot of folders with strange letters appeared on my card. I soft reset the ppc, everything is back again. but some Chinese characters are not readable any more.

Did someone figure out already what is the reason for this?

PS: forgot to mention that I have tomtom preinstalled. My ppc runs a German system from O2 Germany
[P3300, MDA Compact III General] victoradjei:
Same here, but I know why it happened

I also lost all data on my storage card, but was due to syncing with media player on my desktop. I synced music because some files were asking for certificates and that is the way to transfer those that don't play. Unfortunatly clicked the wrong button and card was replaced with music files!

Luckily and unexpectedly restoring the Tomtom backup from desktop restored most of the files on the storage card, and then resetting and syncing (excluded windows media player:) ) with pc brought the programs back. But there are two strange folders that cannot be deleted because they are "system files" in addition to the one called "FilesToBedDeleted". One is namedwith a square symbol and E (but longer name can be seen when explored from activesync).

The TomTom desktop backup really backsup the entire storage card so if you have it you should use it frequently.

Maybe a solution?

I have the same with my xda orbit, I have a 2GB microsd and once in a while suddenly I cannot access the data anymore, the folders and files are looking corrupt, weird names of the files and folders

What helped for me is, to take out the memorycard, insert it again and make sure it is tight in the lock. Then, when you switch it on again, the files should all be accessible again.

I was thinking it might be a problem that the card is not tight enough in the lock so it would lose the contact, so what I did is that I used a small pice of plastic a little thicker than the lock of the sim-card to give higher pressure on the memorycard under the battery. Until now it works fine for me, but I do not know if it is a solution yet, I will have to wait some more days to see if it really works like that.

A lot of people here said that after a softreset everything is OK again, never tried it, so maybe it was just OK coz I took out the battery, it would be similar to a soft reset.

So Now I am not sure anymore if my solution is one, but as I said, until now it is OK. I will post again if I know more.

Is this problem effect only O2 orbit, or all HTC artemis and Dopdo P800W??
[P3300, MDA Compact III General] kurtfhouse:
I have also had this problem on my 1GB MicroSD

Just did a soft reset and then then everything appeared to be gone. When I checked how much storage was left on the card it still had 600MB shown in use but no files were visible.

I also have Tomtom 6 installed and had used it extensivley just before the card corrupted.

I have formatted it and reinstalled everything and have no probs since although I haven't used the sat nav since.
[P3300, MDA Compact III General] firstime911:
Its this occurs because of:

Micro SD brands Sandisk only, Transcend, or Kingston

MIcro SD storages size? 2 gb/ 1 gb

Device ROM: O2 orbit rom, HTC Artemis rom
[P3300, MDA Compact III General] scientist:
Sandisk, 2 gb, O2 Orbit here

Until now still working fine after using my "trick" (I really hope it stays like that), but have to admit that I did not use TomTom since then. When thinking back when my card got corrupt (4 times all together) I was using TomTom all these days when it happened.
[P3300, MDA Compact III General] markdry:
I have only installed TomTom on the card and its been fine for the last week. But to me this isn't a solution as I want 2gb of storage, I'm just scared to load stuff again, but I will this weekend and see how it goes

Phone: O2 Orbit

there is something definitely up with the orbit (maybe other variants as well) and micro sd. I have a kingston 1gb SD and i am getting the funny characters on folders. Do a soft reset and it's fine, doesn't take long for the gibberish to return though :(

Tomtom update

I've just updated the Tomtom version in my P3300 to 6.03 (check Tomtom website). I'm going to monitor closely the consequences of that update on the corruption of my SD. I've still have the intuition that all this affaire is related with DRMs.
[P3300, MDA Compact III General] raido:
that remind me something :rolleyes: first time i got the corrupted data i was using windows media player. maybe it's just a coincidence.

as i sayd before - after clear storage and microsd card format (fat32) i havent had any trouble ( i havent used media player also ) .

i will test my device with media player today and will see what happens.
[P3300, MDA Compact III General] Sky740:
I too got the Media Player response from HTC but I'm not convinced as I thought my card corruption started after I changed the background in the Today screen a couple of times. Either way I'm pleased to note HTC are monitoring this thread and hopefully the '000's of hits it now gets will promt a speedy solution for us all.

By the way, my 2g card doesn't seem to be recognised by my PC. I use XP pro, placing the micro into it's SD converter and the converter into a USB SD reader. SD reader light is on but PC says not detecting the card. Am I doing something wrong - is there a driver I need to install? Thanks for you help.
[P3300, MDA Compact III General] SafarZade:
May be something wrong with adapter or you use old SD reader. Sometimes old USB SD controllers not works with new SD card.

For XP you don't need any additional drivers.

But try go to Control Panel -> Administration -> Control PC -> Disk Manager (may be English OS another name) and Look there all disk devices. Perhaps your card simple don't have Drive Litter.

<SARCASM><IRONY>

I've just found out that in the 17th century, PDAs were already available, as shown in my microSD's root folder (see file attached)

Also, by summing the filesizes, I realized that the card was a bargain, I bought a 10Gb+ for the price of a 1Gb microSD...

Aaaaargh!!!

Media player

I don now if its is related or not, but I am not facing problems since some days when I use to have them very often and I am not using media player at all.

I have faced some corruptions fixed with soft resets but not as before that use to be twice a day and not fixable.
[P3300, MDA Compact III General] kakainis:
Suggested workaround/fix

I would like to suggest a workaround for this problem.

A program that would run like once an hour and check for anomalies on SD card and in case there are any sound an alarm or even triger fat chkdisk routine or soft reset.

Problem is there is no such program yet, I did look into scripting for wm5, but didnt find any mens to acomplish this yet.

SO I would like to ask if anyone here has experience writing apps for wm5 that could whip such a program for us? Oh, please, please, there is got to be some developer that can help us out. (=
[P3300, MDA Compact III General] rickgillyon:
I've been most of the week now without problems. The trick? Mark the whole card read-only. May be WMP, may be something else, but it's cut down/stopped the writes to the card. I want to try just write-protecting the WMP data and see if that's enough, but I've lost my USB Drive so I don't have an easy mirror to work with...
[P3300, MDA Compact III General] RicardoC:
I dont use Media Player and still have the issue (rarely) adding a paper shim has helped a lot. Media Player will hammer the SD card and its accessing the SD that causes the corruption - hence using Media Player or any other software which accesses the SD may cause this issue.

I doubt if changing the files to read only will effect corruption of the FAT which appears to be what happens.

As mentioned above, a routine which does a chkdsk equivalent whenever a file handle is closed after an SD write might mend the damage if we dont get an absolute fix.
[P3300, MDA Compact III General] rickgillyon:
:/ You think that a routine which runs after every SD write might help, but setting read-only flags which prevent most of those writes won't? I'd be interested to hear your "reasoning" behind that...

FACT: I was getting unrecoverable corruption twice a day

FACT: Since making all files/folders on the card read-only, I've had no corruption for five days. It might be a coincidence...
[P3300, MDA Compact III General] debully:
How did you make everything read-only - i.e. which application?

TIA
[P3300, MDA Compact III General] rickgillyon:
Just put my card in the PC, selected everything in Windows Explorer, right-click, Properties, tick Read-Only, OK, tell it to apply to all subfolders and files.

Since yesterday, I've just set the MSMETADATA hidden folder to read-only, left the rest writable, to test the WMP theory. So far, so good...
[P3300, MDA Compact III General] RicardoC:
Because making a file read only stops the operating system writing to a file. But it will not effect the file allocation tables from getting corrupted by an intermittant hardware contact or similar which is what HTC Tech reported to me was the error.

I have had the error appear just by clicking through the SD file structure with File Manager. One minute was OK, tap into a folder, tap back out of the folder and screwed. Perhaps I should have said "when a file handle is closed after an SD access". The files arn't being corrupted, the file allocation table is (info which tells the OS where the files are etc) and this can be repaired with CHKDSK (which happens on a reset).

Having said that this error is so weird that I dont doubt setting the write protect bit of files may help. I tried things and the problem went away for a few days then suddenly started happening again - its a weird one.#

But I re-iterate, HTC Tech have said its a hardware contact issue, which either means a BIOS fix (checking the status of the SD as mentioned above) or a new hardware clip or similar.

I notice that Orange UK have mentioned the release of the SPV M700 (HTC 3600) but have no news of the SPV M650 (HTC 3300) maybe they are waiting for a fix from HTC too.
[P3300, MDA Compact III General] rickgillyon:
When was this? They told someone else this week that they think it's a WMP problem... :)

Once mine has fixed on a reset, all the rest of the time neither a reset or a chkdsk on the PC would bring the files back (except for as lost clusters turned into files). It may be that it all depends on whether any writes have taken place *after* the FAT got corrupted. Who knows, I guess we just wait for a fix. Still, nearly a week now without a problem...fingers crossed.
[P3300, MDA Compact III General] RicardoC:
Yup, you have to be careful and check the file structure of the SD everytime an app accesses the SD, I think writes are more likely to cause an error but reads can too I think. There are 2 FATS, the reset will use the good one but multiple writes (maybe access) will end up corrupting both FATS.

I received this on Jan 10th from HTC Tech.

"Thank you for your email, this is a physical connection issue thats why we will escalate this case. We will contact you as soon as we have an answer.

Thank you for your patience."

Mine improved loads by sticking some padding in to make the SIM put pressure onto the SD.
[P3300, MDA Compact III General] rickgillyon:
Padding didn't help me, and HTC told YuppieScum on 1st Feb that it was a WMP issue! So either they changed their mind or there are different bits of HTC putting out different stories... ;)

Corupt 1GB micro SD transcend and storage memory

I use my htc p3300 for 20 days. no problems at all, but yesterday I installed lot of software + sudoco v2. After i solved 1 sudoco, at the end of the game device froze -> soft reset -> and on storage card I have only empty folders.

In storage memory I had only 6-7MB free, after that it was 20MB free.

I made hard reset, install everything from beginning and played again sudoco. this time I finish first game and in the end I have to wait about 8-10 min for respons from the game but everything was OK. Played one more and this time game ended with error for missing some files. Again empty folders in storage card and storage memory. Device can not boot after soft reset.

I think that the problem is not only for storage card - I ended with missing preinstalled application in storage memory.

Next week I Will test with this sudoco installed in storage memory
[P3300, MDA Compact III General] mo7al:
I own a Trinity, had the same problem with my 2gb miniSD, after couple weeks, the card now is not working any more... I can not format it, can not write to it, it is basically damaged ... went ahead and bought a new sandisk 2gb minisd... same problem with the funny characters every once in a while ... soft reset will solve the problem... I think a new ROM update from HTC is a must now
[P3300, MDA Compact III General] jdl1306:
Well it's not MWP. After the first report of this i did a bit of testing - not much as before i got too far into playing i ended up with a corrupt card after reading an eBook with MSReader, and being 100% certain that all was fine prior to opening the book on the card.
[P3300, MDA Compact III General] rickgillyon:
I agree it's unlikely to be WMP. But if you do use WMP, with the way every play gets written to the library, you're far more likely to get this issue. I saw the library itself get corrupted a couple of times. So I'd advise anyone using WMP to set the library file read-only.

Are your eReader bookmarks on the SD card?
[P3300, MDA Compact III General] martinabooker:
Ok, had exactly this problem and had to format my card about half a dozen times now.

I installed the trial version of "pocket mechanic" and re-formatted as Fat32 rather than 16 and 'touch wood' not a single problem in over a week now. I copied a load of music tracks over last night and will try using media player again, but I think this may have cracked it.....

Has anybody else tried this and had any success in this matter ?
[P3300, MDA Compact III General] martinabooker:
Sorry - Double Post
[P3300, MDA Compact III General] rickgillyon:
I've not had any corruption recently. I disabled WMP writes at the same time I formatted FAT32, but things have been good for a week now and I don't know if it's either of those or a fluke... ;)
[P3300, MDA Compact III General] cfvilela:
Mine is hanging on OK, despite sometimes the funny characters showing up, but nothing that a Soft-Reset can't handle.

So, since the last format (it's been a week now), no malfunctions, crashes, freezes or whatever.

The only thing I've noticed is that the dates of my main memory folders (Application Data, ConnMgr, Documents and Settings, Help, My Documents, Program Files, Temp and Windows) and some of the subfolders are one and the same: 04-04-44 (!!)

As I said, the damn thing is working OK but this date is puzzling me as I don' recall seeing this before the microSD problem started.

Is anyone having the same 'problem'?

Just as an additional info, I haven't performed any hard resets since I bought the device, only uninstall-install (at first) and format-copy (from then on).

Is there a way to manually perform a CHKDSK other than soft reset?

And how about scheduling CHKDSKS after Write operations or when the PPC is idle?

BR
[P3300, MDA Compact III General] RicardoC:
I dont think so, been looking for a suitable 3rd party utility but not found anything. I was using CHKDSK as a generic term, you can run it or Scandisk from a PC but we all know how much of a pain it is to remove/replace the MicroSD in an Artemis!
[P3300, MDA Compact III General] akyriak:
fixed my problem.

It seems that after i copied the wallpaper i use from the sd to internal storage the problem does not appear.

So my guess is that it has something to do with the booting process and when the sd card is mounted ( or however it's called in wm5 )

Haven't reset my artemis for a week now and the filesystem is intact ( and i have some files with greek characters, which make it easier for the file system to show incorrectly )

Hope it helps someone else too and excuse my english.

I am not using WMP anymore, I have everything installed on the 2 gb card again all programs, I am using resco file explorer most of the times , but sometimes I use the file explorer and I didn´t get any corruption in a week when I use to have twice per day.

Another thing is that I have removed the green wallpaper, teme, phone skin and commanager sking and replaced all of them for another ones , I dont know íf it´s related or not.

My problem with "corrupted" card seems to be gone out

Hi all! After some simple actions with my 2 gb card (Sandisk) for a period of 4 weeks i didn't get any troubles as there were before. Hope my way will help you:

- backup non corrupted files from card to PC

- move out and format (for example, through PC's "My computer") your card in cardreader with options: FAT32 (!) and cluster 512 (!).

- place back your files to SD card (by cardreader) and place card to Artemis.

that's all. Not super originally, but it works for me.

About soft i'm using on my Artemis: a lot of.. including WMP. Still no problem after actions described above.

Good luck.

Corruption follows after 3 hours with repaired Artemis

An update after my earlier post about the O2 Orbit that corrupted, then failed altogether. Hats off to UK firm O2 for repairing the Orbit and getting it back to me in just over a week with a new circuit board.

The phone was generally much faster after the repair and that makes me think that some of the slowness I had been seeing (with regular freezes) came from some errors somewhere on the board.

Unfortunately after 3 hours of use and a half-hour of TOMTom navigation it completely lost about 1 GB of data on my MicroSD!

I'm back in the queue waiting for a new ROM from O2, and that is only going to come some time after the new ROM from HTC.

Bugger!
[P3300, MDA Compact III General] rickgillyon:
Did you try Sergie's suggestion of FAT32 512? I've been using that this week, no problems so far, even using WMP.

[P3300, MDA Compact III General] mastelos:
this is an official answer from HTC to a Greek p3300 user yesterday

"From our investigation so far it seems to be an issues with the handset accessing the storage card for longer than it should. There is a Temporary solution. Simply set the Timeout on your device to 1 minute or more.

To do this, Tap Start, Settings, System, Power.

Tap Advanced and set the Turn device off if not used for option to 1 minute or more.

I would then advise that you do not Turn the device off using the power button as this will simply corrupt the card again.You will need to wait for it to power down automatically, after a minute or so."

i do not know if this is a solution but i never had the corrupt problem and from the beggining i had 3min settings for 4 months now

try it
[P3300, MDA Compact III General] rickgillyon:
So you never turn the power off at the power button?

Problem is, if you need to put the thing in your pocket, you then have to wait for the timeout otherwise you'll probably accidentally press the screen...

This is the third different HTC response we've had.

I wonder what the device does on auto-turnoff that it doesn't do if you press the power button...
[P3300, MDA Compact III General] mastelos:
