IPAQ 4150 - SD card corruption problems
Last response: in Cell Phones & Smartphones
Archived from groups: microsoft.public.pocketpc (More info?)
I've been using an IPAQ 4150 for the last 4 months with no problems, however
recently i've noticed that occasionally, my SD card contents go AWOL! - I
don't know exactly when this happens but it is usually after i've sync'd and
removed the ipaq from the cradle or after some normal program installation.
On inspection of the SD card using the IPAQ file manager the only folders
that remain are the Journa Bar cache, Inbox directory, temporary internet
file and history. However when i look at the capacity of the card being
reported it still appears as though all the files/folders are on the card. I
plugged the SD card into my card reader and could see all the files - put it
back in the ipaq - NO files visible except for those mentioned above -
STRANGE.
This problem initially started whilst using a standard cheapo 256MB card -
however i've also now seen the same on my new 512 mb sandisk card.
To confuse matters further, today i just did a soft reset to see if the data
might come back - it didn't. However after accessing a few programs stored
on the IPAQ main memory and then looking at the storage card it appears that
99% of the programs are now back and fully functional!!???
The only thing i'm doing out of the ordinary recently is backing up my SD
card directly to the PC via a card reader - i figured that there is no need
to go thru the activesync conversion if the files are directly copied to the
PC from the card and vice-versa.
I know that there is an SDIO issue with other IPAQs but haven't seen any
posts about this concerning the 4150.
Any help would be much appreciated.

Raj

Why is your Temporary Internet Files folder on your SD card? And when
you say Inbox Directory, you mean attachments or did you move
everything?
If you've got a registry hacking program moving this stuff over there,
try moving it back where it belongs. I've seen reports of one registry
hacking program that moves stuff to the SD card and users report data
loss on the SD card. It may be unrelated, but it is a place to start
testing.

I made a post about a similar problem a couple of weeks ago.
I have an iPAQ H4150 and worked out that by simply running ANY mp3
player software from the SD card I could completely corrupt the card
consistently, every time. I don't see this as a fault of the software
itself, but rather the software exposing a flaw in the operating system
or the SD drivers.
Moving the software to the main memory stopped the corruption.
This only ever occurs when more than 50% of the SD storage space is
occupied. This can catch you out month later down the line as data
builds up to the critical point.
This was on a Kingston 256 MB card. I have yet to test on my new Sandisk
1 GB card.
