SD CARD NOT READABLE AFTER ATTEMPTING TO FORMAT

[Wannabe Geek]

I have a 2gb SD card that was working, but I thought I would be clever and use the SD reader in my Tosh so that I could transfer large files more easily to the card for my exec. But when I was asked to format my card by Toshiba's software, I went through the process and thought it was successful. But then at end of process the phrase "Please stop a SD memory card, then insert the card again" came up, so took card out, re-entered it in the reader and tried to attempt to transfer files to it. However windows then told me that it was not formatted and would I like to format it. So yes, I do, but although windows formatted it, it reduced the capacity from 2gb to 956 mb or thereabouts. It was recognised by the exec again, but with severe consequences as never bought a 1 gb card.

Help please...

Sounds to me like your card reader doesn't read cards bigger than 1 GB. I had the same issue with my 4 GB card. Tried it with a different reader and the PC saw all 4 gigs, never asking me to format. See if you can try a newer SD card reader?

The same thing happened to me with a 1 gigabyte pcmcia card. It was working fine in my laptop then I put it in the card slot on an Ipaq and it also did a format. The card is now exactly half the memory it should be and no way can I get it to work as a 1 gig card even though I have tried formatting on the pc.

I have found that my 2GB card formatted on my Palm LifeDrive was not readable on my laptop. When I formatted using a Toshiba format utility the space on the card was down to 1GB. It did work okay on my JJ. I had to re-format it on my Palm and then for reason it was okay again and could be read by my laptop - I did not use any card readers as the laptop has a built-in reader. And I re-formatted on my laptop using XP format softwsre and the 2GB storage was retained.

@Wannabe, have you got access to another PC or card reader to reformat your card. Also I found WM5 file managers could not reformat and regain the lost capacity

Toshiba are extremely helpful...not! Told me to get another card and see if that works as it might not accept the card. This is a Sandisk card which I believe is made by Toshiba...or at least in collaboration. Am going to check Sandisk for an answer as well...keep the ideas coming please

Hi there.
Try reading this post i made ages ago about formatting and re-newing your sd cards. It might help. It is regarding my 512mb sd card, but the principles are the same.

I strongly recommend using media recover, even if it's only a trial version to "wipe" your sd card to re-new it to it's factory condition. It covers and re-formats the whole card sector by sector.

Give it a go and let us know.

If none of the other suggestions work then try this program that I posted on another thread:-

SDFormatter.zip:

Use it with a card reader, follow instructions and your PPC should be able to read the full capacity.

Thanks for the suggestions, will keep in mind for future. Sandisk took back the card and found that it had become corrupted so have sent out another one. tks for suggestions though.
