casueps Posted March 31, 2008 Report Share Posted March 31, 2008 Writing to any memory card with the card reader is really slow for me. In this same machine with Windows XP it's reasonably fast, and I've noticed that the LED of the card reader blinks at the same interval until the copy finishes. On Linux it blinks fast for a moment, then slow, then fast again, then it stops for a while... The transfer lasts much more and it uses a lot of CPU. Does this happen to someone else?

scarecrow Posted March 31, 2008 Report Share Posted March 31, 2008 No, it doesn't. But since you don't mention card model, distribution, kernel version, it's not too smart trying to explain it... Quote Link to comment Share on other sites More sharing options...
mindwave Posted March 31, 2008 Report Share Posted March 31, 2008 a couple of things to tyhink about 1) whats the card formatted in? ntfs? fat 16? fat 32>I'm leaving the linux formats off because you said you could read it from windos. ALSO is this an internal card reader that came w/ your pc, or an external reader. I ask that because I have found that MANY of my "internal" usb ports are USB 1.1 (even on my newer stuff. so even if i hook up a USB 2.0 hub its only going a 1,1apeed. Just a few thought. j Quote Link to comment Share on other sites More sharing options...

It's a Kingston 1GB SD Card and the kernel version is 2.6.12-17mdksmp Quote Link to comment Share on other sites More sharing options...
scarecrow Posted March 31, 2008 Report Share Posted March 31, 2008 Likely you need a newer kernel revision or/and Mandriva version than 2006.0 (which you apparently are using) to get better performance from the card reader. Is it an external USB SD reader, or an embedded one in a laptop? Which vendor/model? Quote Link to comment Share on other sites More sharing options...
