Add Layer Excruciatingly Slow from SD Card.

PatrickMurphy · ‎08-07-2010

HI all,
I have and HP211 with an 8M SD card. I store almost all of my data on the SD card and have a lot of Folders and Files on the SD card. I just tried to add some layers and it took 5 or more minutes to get to the file. Each time I went into a subdirectory the wait spinner would go on and on and on.

Is this normal, a function of card speed, or what?

Thanks,
Pat

Here is an interesting development. If i open ArcPad and don't open a preexisting project and just try to add a layer, it recognizes the SD card folders in a flash. If I then try to open the preexisting project and try to add a layer, everything works great. Weird. Any ideas what is going on? sounds like a bug to me.

It is two years later and the same problem and the same workaround are still needed for me. Arcpad 10 R2 Build 30

Patrick,

What is the folder hierarchy on SD card? What type of SD card are you using with the HPs iPAQ 211 handheld device? Does it have fastest read/write speeds available? According to specs, the HP iPAQ 211 supports SD/SDIO and CompactFlash HC memory cards. Some items to note about SD cards:

    A newer card may offer greater capacity than the host device can handle.
    A newer card may use a file system the host device cannot navigate.
    Use of an SDIO card requires the host device be designed for the input/output functions the card provides.
    The organization of the card was changed starting with the SDHC family.
    Some vendors produced SDSC cards above 1 GB before the SDA had standardized a method of doing so.

Does altering the Default Maps & Data Path help to resolve this slow behavior? The path can be
modified in ArcPad Options > Paths tab. Does turning off unneeded extensions in ArcPad Advanced
Settings > Extensions tab improve time to load the data? If not, please contact Esri Support and submit support interaction so you can work with ArcPad specialist to troubleshoot behavior further. Additionally, latest release of ArcPad 10 is ArcPad 10.0.3 and download now available from Customer Care Portal.

Cheers,
Denise

I'm actually experiencing the same thing except all my data is in the on-board memory. I created the project with the ArcPad data manager toolbar. If I open the project first and then attempt to add additional data, its extremely slow. If I open a new blank map first, open the add layer it works perfectly. I can then open the preexisting project and adding additional data layers works fine.
