I just got the Plugable USB 3.0 PCIe card and a Lexar USB 3.0 external card reader in an attempt to speed up my CF card reads. I’m running Windows 7. Unfortunately, the drive “disappears” a few seconds into any read – the copy stops, saying that the files cannot be founds and the drive, while still appearing, shows as empty. There’s an LED on the reader and it goes from flashing during transfer to solid (briefly) about the time the transfer seizes to off. I have to reboot the machine to get the drive to reappear. I can get small amounts of data to transfer from reader to computer, but anything over about 10-15 seconds stops. I’ve tried a couple of CF cards. I haven’t experimented much with writes, but if anything they seem to seize up faster.
Given that the LED goes out (and reports of other problems I’ve heard about USB drives), I thought it might be a problem with power management, but I’ve tried changing the settings within the control panel and the driver utility without success.
I’ve got the molex power connected to the card, but it is on a line that supplies a fan. Any diagnostic that would report if it wasn’t getting enough power?
I don’t have access to any other USB 3.0 -equipped machines to test the reader.
Any ideas? Thanks.
