CF slot not recognised in USB 3.0 card reader Windows 8

Hello

I upgraded(?) to Windows 8 and now the CF card slor in my USB 3.0 all-in-one card reader is not recognised. The LED flashes continuously but the card does not show up in Windows. The SDHC slot is OK. I've tried different CF cards and the old USB 2.0 reader works with them.

Any thoughts?

"Any thoughts?"

 

Have you written to the Windows 8 support forum and the manufacturer of your USB 3.0 all-in-one card reader's support forum and seen what they suggest?

Well it is a Sandisk card reader, which is why I posted here. I have since upgraded the bios and chipset drivers, both of which were said to improve USB handling, without result.

I report the same problem. My SanDisk card reader (USB 3.0) has worked well under Windows 7. I have just upgraded to Windows 7 this afternoon, and the CF slot no longer works. The SDHC slot is still fine. I think there is incompatibility between this reader and windows 8, on the CF slot. Can someone at Sandisk try to reproduce this problem? It's frustrating as this reader is the only way I have to get photos into the desktop PC.

To elaborate, the blue light under the CF slot keeps flashing when the CF card is in it. Lightroom's Import dialog freezes. The Computer window never shows the card.

If a SDHC card is put in, it shows up instantly.

The CF card is a Sandisk Extreme III 12GB and the SDHC card is a SanDisk Extreme 32GB.

Another update: if the CF and SDHC cards (see above post) are put in the reader, none of them show up. So the CF card jams the reader. Please some one help to resolve the issue.

Until you get a fix I recommend you back out your Windows 8 upgrade.

No need for that. I have found out that it will work if plugged into a USB 2.0 port. There are other USB 3.0 card readers that work under Windows 8.

Hi Ed_P: are you an employee of SanDisk? Why I ask is I hope someone at Sandisk notices this thread and takes action.

 

narrowgauge: thanks for the tip! It could probably be more useful to someone else than my particular situation: the files from the Nikon D800E are routinely 50-70MB a pop, so I really need the USB 3.0 speed.
