OS: xp home sp2


SDHC card is not recognized

Hi,
I'm new to this site. Excuse me, if I post in wrong threads.
I run compaq SR1710NX with XP home sp2. This came with compaq supplied 7-in-1 card reader. I can read upto 2gb without any issues. I tried 4gb SDHC, the system locks up. After a while, I get error message: "F:\is not accessible. The request could not be performed of an I/O device error".
I went thru' several searches, and came across microsoft KB 921413 (SDHC issues), 923293 (sdhc support), 934428 (to support greater than 4gb SDHC). Which one should I pick? The file updates included in KB is confusing. The latest dates have lower release numbers for the files (see 934428).
I hope I am on right track. Can some one suggest, what updates should I download? Thanks alot.
