preparing SDcard, checking for errors.

I've just purchased a Samsung Tab ll, I purchased some Samsung 32gb SD cards, when I insert the cards the icon on bottom of the screen says preparing SD card, checking for errors. I can't format the cards nor can I mount them. When I look on storage, it says waiting for encryption or decryption.there is no way to encrypt them, encryption setting are greyed out so can't do anything there. I think it can't handle the 32gb cards, even though says they can, any ideas?
 
Ever try formatting the SD cards from a computer then trying to put them in? Is this device rooted or no? Or if you have cwm mod on your device I know that has alot of SD options on it lets you format partition and like 4 other options can do it right from your device I got it when I rooted my phone and I love all the feature it has hope this helps
 
Yes tried formatting on pc, no good, tried to do as ntfs, tablet didn't recognise file format, so did reformat from tablet, thence same error again! Have logged call with Samsung, as no one has a fix.
 
Ugh. I've recently encountered a similar set of symptoms on my Galaxy Prevail with CM7 beta5 on it. My SD card is a class 4 8GB SDHC card, SanDisk brand.

Nearly every boot, I'd get the "Preparing SD Card, Checking for Errors" message, and it would not go away until I manually ejected the card and reinserted it. Later on, not even that would make it go away.

I solved it, though, by putting the card in my USB SD card reader, mounting it in windows, and doing a full format in FAT32 -- as in, DO NOT check the "quick format" box. Been nearly 3 days since and I have not seen the error come back.

ianmacster, you may have the same situation -- would you try mounting the card in windows with an SD card reader, right-clicking it in windows explorer, select properties>Tools>Error Checking> Check now? When I did that, it would scan almost all the way through, then the SD would randomly dismount itself from windows without completing the scan. This would mean something is seriously messed up in the file system or the File Allocation Table, I would think.
