Microsoft has released an update "KB976092" for Windows 7 which fixes a data corruption issue for Secure Digital (SD) cards. If you are using Windows 7, you should download and install this update.
Problem overview:
You have an NTFS formatted SD card. You use Advanced Direct Memory Access (ADMA) to transfer data between the SD card and a computer that is running Windows 7 system. When you transfer data from the computer to the SD card, the data on the SD card may be corrupted. Additionally, unexpected problems may occur when you try to use the affected data.

hey VG, i've been having HUGE problems with my extrenal memory of 420Gb.
Like when i transfer something big, to or from it, sometimes it freezes and stops tranfering, then the window closes and ALL of my USB connected devices get unrecognized, unless i restart again.
And if I don't restart, i won't hae anything recognized and my computer might freeze and crash.
Do you think this will fix it?
Specs:
Windows 7 Ultimate 64bit
2.6Ghz
8Gb of RAM

first off @maniaslayer9 is that 420 gb hard drive space cause i am sure its not memory. anyway the answer to your question will need more info. I am thinking since you can't transfer something big that you are on a fat32 file system? if it is then format it to ntfs you are then allowed to transfer more than 4 gigs at a time. if that is not the case it might be a hardware issue that will require more issue. maybe VG could help you on that part lol anyway check if your file system is a fat32 and format to ntfs

@ Devanche Solanki

Please tell me how

Who in their right mind formats an SD card to NTFS? 90% of other devices (cameras, MP3 players) can't read NTFS. This is probably a problem that has only hit Microsoft employees (because MS wants everybody and everything to use NTFS), and because their FAT32 patents are close to their end-of-life (patents supposedly last 17 years, and FAT32 was introduced in 1996 with Windows 95B. 1996 + 17 = 2013).

I use my ReadyBoost card in exFAT...

I think During an ADMA transfer process, the Secure Digital Bus Driver (Sdbus.sys) converts the DMA data structure of the operating system to the ADMA data structure of the SD card.

You can convert a fat or fat32 drive to NTFS without losing any data and this is a quick way to do that.

I have converted my western digital external drives and they are way faster and allow files larger than the 4gb limit that is on fat drives.
Visit the link or type this command
convert : /fs:ntfs
so if urs is c then type in the command "convert C: /fs:ntfs" without the ""s
Hope this helps
