2gb SD card becoming corrupt

[scotjames]

I used my Qtek 9100 with a PQI 512mb miniSD for a good few weeks and it worked flawlessly. I had another unbranded 2gb miniSD card and decided to copy everything on to that and use it so I'd have more space for music. To cut a long story short, this worked fine for a few days then I started noticing WMPlayer acting up. I checked the card and loads of files seemed to be corrupt. After playing around with it for a while I eventually gave up and decided it must be a duff card.

So, I bought a 2gb PQI miniSD which I had read good reviews off. However, I'm having the same issue. I've tried everything I can think of 1) hard resets, 2) soft resets 3) re-installing apps 4) formatting in a couple of different PCs with a couple of different card readers 5) formatting from the StorageTools on the phone 6) formatting using WM5torage.

I can install apps and they seem to be okay, but then when I try and run them I get errors and when I look at the card its because of corrupt files.

I have no idea what is going on and I'm at the end of my tether.

I'm using the latest Qtek 9100 ROM from their website. Is this perhaps a bug in the ROM? Would I be better with another ROM? Which one? Will this still leave my 'phone SIM unlocked if I use a non-standard ROM?

HELP? Please?

Hey,

I do hope this is within this topic! :confused:

I've got aLmost the same problem, except I have some files just disapear on my 2GB mini, and some stay!
Lost a GIG of music, and most of my WORD docs, [60MB] and it left me 2MBs after removing Skype!

Real WEIRD!

Ive got a 8125 and stuff on the SD card just disappears after I remove an app!

Since this has happed more than 3 times and the 2GB mini tested OK, whats up with the device!

Is it the connections in the device to the SD card, or what?

Thanks for XDA-developers!

I have a 2gb card in my Qtek 9100. I've had it for about 2 weeks, and I got the card the day after I got the 9100. Sofar I haven't noticed any missing files. It's a 2gb Sandisk

I just thought to add this. Do you have the enhanced performance option in RegistryWizard enabled, or have you made the registry change to enable caching of the file system?

I was noticing that my recent programs on the start menu were being lost on occasion during a soft reset. I disabled that "enhanced performance" (caching) and that problem has disappeared. It makes sense that it would cause data loss or corruption, since data is being cached, if the cache doesn't write out before you reset, you loose everything in cache. I didn't notice any real world performance increase, so I will just leave that disabled.

If you have that setting enabled, and soft reset often, then that might explain the data loss/corruption

Well, I got hold of CnetX Flash Format program and this seems to have done the trick. I installed it and tried formatting the 2gb card as FAT32 - this gave the same problems I had before.

Formatted it as Fat 16 with 32k Cluster and lo and behold its working like a dream. Copied all my stuff from 512Mb card to it and now I'm syncing all my music over.

Fingers crossed it stays this way!

[scotjames]

.....just failed syncing my music over. Managed to get 950Mb of stuff on the card and then it started doing exactly what it was doing before. Hmmm....i'm really stuck now.

[madefree]

Howdy,

Well now today all my stuff on the care is gone POOF excect one little word file and a few omaclock things and a few folders!

All music is gone but the music folder is there WOW!

I already reformatted a few weeks ago to Fat 32 form the other one!

Hey d0ug,

I dumber the a bucket of rocks, so where is th RegistryWisard enabled or disabled at if your talking to me?

Thanks and sorry for the dumby thing? :confused:

Hey d0ug,

Thanks for the link, and dnloaded it but I really know why, or want for?

Ok whats this for, the storage card or what?

Thanks for your valuable time, and really sorry for the extra stupid questions, as this device in not my first device but I didn't have any problems with the X50 so I didn't have to learn to work on it! :eek:

Hey scotjames
you said .....just failed syncing my music over. Managed to get 950Mb of stuff on the card and then it started doing exactly what it was doing before. Hmmm....i'm really stuck now.

Yep I moved 1 + GBs music into a "music" folder again!

Installed a app from xda, here called omanclockscaller.exe or something like that and set the overclock (speed of the processor) to 240 and the underclock to 150 (which was stated to work on another 8125)
and my device FROZE to the max couldn't soft reset or nothing so I had to do the HARD reset!

Looked in the SD card saw the folder "music" and NOTHING in it, just blank!
All subfiles were gone, POOF!

When to the main area of the SD card and ticked on a Mp3 file that was sitting there and it said player said "file stopped." 70%
Went to another MP3 file, tapped, and it said blah, blah "end of file" and would not play!

SO everything on the SD card, cept dah empty folders are either
1. corrupted
OR
2. GONE bye bye!

So NOW since the 8125 might not be the "slowest" brick on the block, and wont run, Skype unless its "overclocked," and I can't go thru another 50 some pages on xda to find the "fix" for dah SD wiping weirdness, and the overclocking tricks of the techs, I guess I get to go to Cingular, exchange dah phone (as it ain't no good as a PDA, but a great heavy phone) and than sell the NEW one on ebay for 350 with the New 2200MHz extended battery, and someone who is more techey than I can enjoy tweaking the thing!

Ive done 5 full Hard resets and have had to redo most everything, 5 times, settings etc, and its getting real time consuming, to state the least!

So since I got this pos on ebey and it has a 2yr. warrantee I guess its getting ready to get gone!

Hope someone like d0ug can help you out, really!

Later!

What brands are the Memory Cards? Where did you buy them from? Is it just in the Wizard that the card is being corrupt or does it work flawlessly in a memory card reader? Cause from what I've read it sounds like PEBKAC.

[scotjames]

My first card was unbranded so not overly surprised I had problems. This one is PQI but I think perhaps its because PQI cards are MLC (multi layer construction). Apparently Sandisk are SLC (single layer construction) and they should work okay.

I might just have to fork out more money and see.

The card works perfectly in my PC with card reader.

Excuse the ignorance but what is PEBKAC (or should I not ask!)?

Ah the reference to PEBKAC was more about the other guy. I think you've just got unlucky with the memory cards.

[scotjames]

Does the MLC/SLC thing sound viable? Has anybody got experience of using Sandisk 2Gb cards with the Wizard?

[madefree]

Hey scottjames,

I don't know if this helps as I was using Winamp files and wasn't using Win Media on my PC so that may be why the files got corrupt or just disapeared when I went in again and tried to play them!

So I diched Winamp and am using the gates special and so far so good! :D

I don't know if that may help but hope so!

Cingular is going to exchange my phone for too many other reasons!

Have a good one, and thanks everyone here!

My 2gb card is a Sandisk. No problems sofar. The card is only about half full right now. Ill fill the card up and play with it awhile and see what happens

I've been using a SanDisk 2GB card to capacity sine April of this year, I change the contents of the card pretty often as I use it as my mp3/video player, using both the WM5Storage program and a memory card reader in my PC. Has been flawless.

Well now the "THING" is doing the strange things again. . .
settings > memory > SD card says FREE 1903.97 out of 1904.13
NO 5ooMBs of music or word docs
But
when I go file explore > Device > SD Card I see all the music file and even play them OK

WOW thats real weird!

Cant see files in one place but plays the music in another???? :confused:

So whats UP with this?

Anyone?

[d0ug]

I filled my card lastnight, and have used the pda as normal thoughout the day today. accessed files, copied files, created files, deleted files. I'm not having any issues with my sandisk 2gb.

[scotjames]

Thanks everyone. I'll maybe just get myself a Sandisk card and let you know how I get on.

[steffross]

I have a Sandisk 2GB and whilst not experiencing the issues above I do have other problems.

When accessing eBooks via Microsoft Reader or playing video files via TCPMP the device will occasionally freeze and the apps cant even be killed by the taskmanager. I have a standard TMobile install and these are the only two additional apps that have been installed.

Ejecting the card usually frees it up.

To be fair I haven't yet tried the card in another device to establish if the card itself is faulty.

[rodalfa]

I have been using several and different minisd cards (512mb, 1gb and 2gb) and I have had exactly the same problems:
- Sometimes some directories get corrupted.
- Sometimes some files dissapear
- Sometimes some strange files appear, with strange propiertes (size bigger than 2gb? special characters in the name?)

The explanation of the file caching could be reasonable. But I think that it could be also related with the activesync: how and when do you disconnect your cable from the pda?

There is no way to know if there are communications between the pda and the pc, so if it is accessing to the card and you disconnect it... image, easily the card file system can be corrupted!!
Suppousedly the activesync simbol shows when you are syncing, but: you can be using the internet connection through AS (and having IE temp in SD!), you can be using lots of 3rd party soft that communicate to the pda through AS...

I thing it's ANOTHER M$ mistake: there is no secure way to disconnect the pda from the computer!!!

I am having the same problem with a PQI 2GB bought from Fry's(PLU# 5044075 and P/N: AE62-2030R01F4) in Houston, TX. When I try to download something from an FTP Client to the storage card, it fails and when I leave stuff on it, it becomes corrupt and stuff disappears.

I took my roommate's 64MB PQI from his Sidekick III and it worked like a charm. It was as follows.

1 Head
1 Cylinder

Type: FAT12
Sector: 512 Bytes
Cluster Size: 16 KB
BackupFAT: Yes

I have downloaded this program here...

http://www.softwinter.com/storagetools.html

It has the option for FAT12 while FLASH FORMAT will only give me the FAT16 and FAT32 options. It may however not be an option due to my card not supporting it as the program above will not let me flash it as FAT12 either.

I'm using the above program to defrag and repair my card right now.

[Farsquidge]

Have any of you people been removing your cards and placing them directly in a PC/Laptop??

On some older PC/Laptop systems, SD firmware can only handle and format 1Gb or less. Corruption occurs when the FAT table is written to by the PC.

Had the same frustrating problem myself for a while and now NEVER take my card out of the phone, always transfer files via Activesync browser.

You may have to obtain an updated formatter (best I found was from the Panasonic site) to reformat any corrupted SD cards and check out your PC/Laptop support site for an updated SD driver.

Hope this helps.

hey all, ive had the same exact problems here, with my 2GB PQI miniSD...im so confused!...i have an 8125(my brothers) and an MDA(mine)...my brother has the 2GB miniSD and he told me the problems he was having, and its pretty much everything being discussed in here...i use a 512MB card on my fone, and its working GREAT...i install all my programs in there and nothing ever went wrong...i installed his card in my fone to see if it was the card thats mest up, or the fone, and turns out, that the card wasnt working properly...i took it out and put my old 512MB back in, and it wouldnt discover it...i had to take it out, soft reset and put it back in for it to work properly again...i was thinking about getting a 2GB miniSD but, if this problem consists, then i dont know if i should or not....

[Malik05]

anyone figure out a solution to this problem?

[pzucchel]

Hi to all,

i had a 2Gb minisd working on my wizard since about 3 months, it works without any probleml and through various rom upgrades. I bought it from www.mobymemory.com, and it is unbranded (e.g. not the sandisk one). I don't think there is any issue with WM5/Wizard HW.

[paladin77]

Hey guys..
sry to break the news but i am almost sure this is an issue with HTC...apparently it can affect any card but kingston and sandisk more specifically...theres is a huge thread on artemis forum on this problem.. After alot of turmoil HTC released an updated dll file for sd handling and the artemis problems were gone..i tried it and too bad it doesnt work for the wizard...someone should check if there is a wizard version lying around ... any other solution just wont work trust me ;)

[akashastrega]

I have a 2gb Transcend, never had issues with Transcend before. My phone dropped today and my battery fell out, after that, I lost everything...yet when looking at storage mem on both the phone and popped into the pc via the adapter, it read that 1.5gb were used...USED yet absolutely blank card, no files showing at all. I am currently copying everything back over to the 2gb, but am wondering if the sudden loss of power (because the battery popped out) has anything to do with it, as it was working without issue just prior to being dropped.

ANY THOUGHTS????
Help please, I don't want this issue to re-appear.
Thanks.
