Solved Windows 7 issue with corrupting SD data

June 28, 2015 at 12:02:47
Specs: Windows 6, P4 2.6GHZ/PC3200 1.5gig
It seems that Windows 7 (occasionally) causes the pictures on my SD card to become corrupted (illegible), or have the wrong file name. I searched the NET for this and found Microsoft's fixes, but neither one works, i.e. they say they don't apply to my OS (Windows 7 Home Premium). Does anyone know how I can fix this problem?
Thanks,
........... john

KB976092 was originally dated 23 Nov 2009 and included in Win 7 SP1. It is not therefore related to your issue if it was recent. The reason it won't install is because it already exists. A computer doesn't suddenly require an old patch if it was working previously.

The only reason it could apply is if you've just acquired your Windows 7 computer or re-installed it without service packs, otherwise you need to seek another cause.

Let us know the history, like how long have you had this computer, what is the service pack level and when did the SD card trouble start?

Did you try the Device Manager suggestion given in #4?

Also try cleaning the SD card edge connectors with a pencil eraser and popping the card in and out a few times to clear any oxide off the socket. I still think the most likely cause is that the card is wearing out - try another one.

Always pop back and let us know the outcome - thanks

It might not be Windows that is corrupting the SD card. It is more likely that the card itself is reaching the end of it's life, requiring replacement. They can give out after a long period of use.

Anything on an SD card or usb/flash drive is best considered " temporary"; i.e. to be transferred asap to either cd/dvd or a hard drive, where it will be much safer.

SD cards and flash drives do have a life span that generally is a lot less than hard drive etc. They will ultimately start to fail; they have a limited number of read/writes etc. which whilst quite high, nonetheless are not unlimited.

Thanks Derek/trvlr,
Yes, that could be the problem; but I have not had this problem until I started using these (two) card in Windows 7 (previously they have only seen Windows XP). Also, there seems to an online acknowledgement that Windows 7 has corruption issue(s) around SD cards, so I'm thinking that it's not likely the cards themselves.
However ........ thanks for your help.

I assume you have a card reader internal or external.
There should be 4 drive letters assigned to the reader and visible in Explorer.

Possible the card reader driver may not be installed properly or corrupt.
Uninstall the driver in Device Manager and unplug the reader and plug in the reader again. The driver will be reinstalled.

If you see this file on the flash drive: ReadyBoost.sfcache, disable ReadyBoost:

Hi sluc,
The Windows 7 machine has a built in card reader. The Windows XP machine, which seems to be fine, has a SanDisk USB card reader. I never had trouble with these cards until I started using the Windows 7 machine.
Doesn't anyone take anything from the fact that Microsoft acknowledges that Windows 7 has SD card reading issues that cause data corruption (which, by the way, neither of the fixes work on my machine)???

I wasn't aware of the win-7 and SD cards issue; so for me that info is a learning curve and useful too.

The general comments re' reliability/life of SD (and flash drives) is also well intended; as frequently that is the cause of many a problem with them.

That the info in the article (posted by sluc) doesn't help resolve your current problem... is not good news...

That XP system with an add-in/plug-in card reader is OK and the win-7 (built-in) is not, does tend to point the a possible issue with the latter - built-in reader)?

What happens if you use the add-in reader in the win-7 system?

"Doesn't anyone take anything from the fact that Microsoft acknowledges that Windows 7 has SD card reading issues that cause data corruption"

Could you post a link to the site where Microsoft acknowledges this? I've looked all over Microsoft's site and nowhere do I see any indication of this issue.

I found https://support.microsoft.com/en-us... which indicates the driver Sdbus.sys had a bug where incorrect handling of a parameter could lead to data corruption. "Had" being the operative word. Looks like it was patched out back in 2011.

It still sounds like the SD card's dying, but if you're insistent it's Windows 7, restrict your usage of these SD cards to your WinXP computer.

Hi,
Here's the link to Microsoft's patch <https://support.microsoft.com/en-us/kb/976092>, neither of which my Windows 7 machine will allow me to install, stating something to the effect that these patches are not meant for my system. I could not find any other patches for the Windows 7 card reading issues.
Thank you all for your help. I'll post a solution when/if I find one.

Just to say that if you saw my #10 earlier it has now been completely re-written in the light of my findings about the patch - so give it another read.

Hi Derek,
I only bought the computer, OS and all, about a month ago, so I don't know much about it. I looked at the update list, but couldn't find the one for the SD card fix. However, the list doesn't have any information for updates before March of 2014. The headings are there, but no details. But I do have SP1, so if you're right, then this fix is probably installed already.
I have not tried uninstalling the the card reader yet. I will do that next, along with the eraser trick; although I doubt that that's it, since the cards seem to work fine on my XP machine.
I'm now a little gun shy about it ..... screwing up my images is not my idea of fun. I will also try an external card reader, and see if that helps.
Another thought. Could it be the contacts on the reader? Do you know of a way of cleaning them?

Not easy to clean contacts on reader - easy to bend something. Usually just popping a card in and out a few times cleans them.

Alright. I have cleaned the contacts of the reader, as best I can, uninstalled and re -installed the card reader drivers. Right now I'm tired of the entire issue, not just because of corruption issue, but I find Windows 7 very unco-operative. It refuses to allow me to change, almost anything, without demanding that I satisfy it's oppressive permissions regimen. And I'm beginning to think about switching to one of the Linux builds.
Thank you all for your help. I very much appreciate it.
