Anyone have this problem?

[HuntingMartians]

I bought a new "SanDisk 8GB SDHC ULTRA II Card". Now the issue I have is my card reader a Lexar media USB 2.0 card reader cannot read the card. My computer freezes when I try and open it up. I have tried two card readers on my computer (both failed) and a card reader on a printer on a serparate computer and it came up with "read error". Now is it because it is a 8gb card that these older card readers are having problems with it? Or is it a card issue? My camera reads and writes to it fine. I managed to get the pics off the card by using the camera connected to the pc. But I would rather use a card reader.

Any thoughts?

It sounds as though your card reader and printer aren't compatible with SDHC cards (new high capacity cards are different to older SD cards). My card reader in my laptop won't recognise them either, you need a newer card reader!

What Chris says.

I have a Lian-Li 3.5" reader fitted to my Lian-Li case and the Dell UltraShap 24" has a built-in multi-card reader. None can read the High Capacity cards as the formating is different, so yeh - you need a new reader (I bought a cheap USB Transcend M3)

EDIT - I didn't read the full post, but as mentioned above, a new card reader should fix it.

I had the same problem - got a card reader from poundland that reads sd/mmc/rs-mmc cards including the high capacity (HC) cards. It's USB2 and doesn't take other formats (eg compact flash) but for £1 it was well worth it to use my 2x4GB SDHC cards. Give them a try if there is one by you.

Have you tried connecting your camera to your computer with a USB cable and downloading for comparison?

I'm not sure the card reader should make any difference, the card is seen as another hard drive by the computer, as far the readers concerned it's just a connection to the card, the size shouldn't make any difference. There are a lot of fake cards doing the rounds, these may well cause problems, some are very realistic, try another card in the reader, that will eliminate one problem. Wayne

Unless your card reader was made to read SDHC it will not work as the formatting of the card is different and different firmware/drives are required which is why you can copy the photos off of the card when its in your camera and not via your card readers.


From http://en.wikipedia.org/wiki/Secure_Digital_card

SDHC (Secure Digital High Capacity, SD 2.0) is an extension of the SD standard that appeared in June 2006.SDHC allows standard-compliant capacities in excess of 2 GB. SDHC cards are often formatted with the FAT32 file system. It uses the same physical and electrical form factor as SD, but the SD 2.0 standard in SDHC uses a different memory addressing method (sector addressing vs byte addressing), thus theoretically reaching a maximum capacity of up to 2 TB (2048 GB). However the SD Card association has artificially defined the maximum limit of SDHC capacity to 32 GB.SDHC cards only work in SDHC compatible devices, but standard SD cards work in both SD and SDHC devices. The SDHC trademark is licensed to ensure compatibility.

Hi Wayne,

This isn't the case as was mentioned in post#3 and #8.
Older card readers will not recognise and read the newer SDHC cards.
The same holds true for older cameras, they will not be able to use/write to the High Capacity cards unless the manufacturer releases a firmware update to cater this.
I needed to update my PENTAX *istDS firmware before it was able to use SDHC cards.

SanDisk must've had plenty of support issues when they started supplying SDHC cards, so there's the 4GB version that comes complete with a reader.

My first 2GB card turned out to be a fake, but worked with no problems. When I first got a genuine SanDisk Extreme III 2GB card for my Pentax *ist DS, I was mightily miffed to find my card reader was no longer suitable and there was hardly any info or hardware available for the SDHC requirement.
