SDHC card not recognized with Vista on Acer PC and laptop.

If only 3GB is recognized it isn't a 64bit OS.

It's not your card reader, the SDHC mini firmware is dead that's why your reader cannot detect it. Warranty, return it to SanDisk for a new one. Every hardware you plug or attach to a PC or Laptop has what is called a firmware, a mini program that communicates with your PC and Laptop that's how they syst

There are no 8GB SD cards. Cards this size are SDHC (High Capacity). SD and SDHC cards fit the same slots, but many cameras won't work with the SDHC cards. SDHC is not backwards compatible.

fo vista u have install vista drivers frm ur acer driver cd try definetely it will cme

Best solution for SDHC is a high speed card reader.
One that hooks up via Firewire.
Some of the compatible cameras with the higher capacity, faster cards are not recognized when connected to the computer... great work around and downloads are quicker too.

You'll need one of these:

You can download the drivers directly from Acer.

Just choose "drivers and downloads"
Then "notebook"
Then "Aspire 9300"

On the right window, you will see available drivers. Once you highlight each one, you will see what operating system it is for in the "download details" window.

If Acer screwed up fixing your problem the first time (and it's evident that they did) they are obligated to fix it a second time, and if they cant, they are obligated to replace your laptop.
