I bought a deer cam (trail camera) at Walmart and a PNY card with PNY Multi-Slot USB & Flash Card Reader P-UBSDRDR21K-RF. I can't make them all work for me. PNY card reader has no instructions on the package neither on their website and their support is a joke. When I plug in this multi-slot card reader into my PC (I tried two different PCs) something isn't right. I get no results, just empty folders. The card is new and has data on it. Both products come from PNY, both were purchased at Walmart and both are going back to Walmart for a full refund and I will never buy a PNY product ever again.

According to the Acer Support web site the Aspire One cannot boot from a SD card so you will need to give more details of exactly what problem you are having when booting this netbook.

The documentation for the Acer Aspire One AOA110 can be found via this link.

If it can-not read the sd card try using a different one if the same problem persists means the sd card reader is faulty and will need replacing by either sending it back to acer to have them change it or by checking ebay to see if a replacement one is available at a cheaper rate if your computer is out of warranty

Here you have audio driver for Acer Aspire one ZG5

If you have not used this card with this laptop before it is possible there is an incompatibility with the card type and the reader. SDHC cards are generally no compatible with card readers built into laptops. IT is due to the compression algorithm used to increase the storage capacity on the card. There is no PHYSICAL difference the higher storage capacity is made possible by configuring the way data is stored and revision 1.0 of card readers arent compatible. Try going to Acer and downloading a newere version of the card reader software if this doesnt work, try an older version card if possible.

Your netbook should read SDHC(over 2 GB capacity) memory cards. The problem might be either the card slot driver, Which you should download if a newer one is available. Or in case you format the SD as DOS then it will only have around 2GB of space, You should format it as DOS32 or NTFS so you get the full capacity for the SD card. Some pirated rather cheaper memory cards have a lower actual capacity. With some compression technique the capacity presented is higher than it actually is. If you format it then it will show the real capacity. hope that is not the case!

Good Luck!

Push the card in just a bit until it clicks, then it should release unless it is stuck. Sometimes this happens with new SD cards until they are inserted and ejected a few times.

Check to see that the SD card is inserted the right way, not upside down.
