[opensuse] USB memory stick issues
Hi, I am having this weird problem with a SanDisk Crizer Micro memory stick. When I try to copy large files 3.7 GB it has a capacity of 4.0 GB the process starts at approx. 600 kbps and it is going OK and after a while that speed goes down to a 56 kbps and it stays there. This is when I run it on my Toshiba laptop Satelite 2450 with 2.8 GH processor and 1GB RAM running SuSE 10.0. When I copy large files 2 GB on my work machine an IBM/Lenovo R60 with duo-core intel processor and 1GB of ram I get speeds of approx. 8+ GB per second and it is constant I run SuSE 10.1 on that laptop. The stick supports USB 2.0 and 1.1 so I do not think it is hardware related as the Toshiba may only support 1.1 but the speed should stay constant. I have noticed that 10.0 is quite slower with usb transfers compared to 10.1 is this a driver issue? How can I find the version and maybe upgrade it??

Sure, there is problem with sync mounting of usb devices (#105871) You can test it by type mount -o remount,async /dev/sdb1 (if /dev/sdb1 is where your disk is mounted) do not forget to run async, after copying. If problems will still prevail, post bug.

I noticed this not being an issue under 10.1 - USB transferres are MUCH faster under 10.1 than 9.3/10.0. -- kai www.perfectreign.com || www.4thedadz.com a turn signal is a statement, not a request -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

If problems will still prevail, post bug. Sure I will try that. I tried windows 00 in vmware with the same stick and run a lot faster I guess vmware has a different driver or something... Probably unrelated again, when I put the same stick in using SuSE 10.1 it does not load all the time sometimes I have to restart the machine or take it out and put it back in again...right now it just does not work.. K3B show an entry for "SanDisk - U3 Cruizer Micro" the stick has software from that company that allows you to install programs and run them under windows. I am not sure if that is what is interfering with it loading properly. When I click on storage media nothing shows up... Any suggestions on that???

I noticed this not being an issue under 10.1 - USB transferres are MUCH faster under 10.1 than 9.3/10.0.
They should be using the 'flush' mount option which gets you that
improvement.

I've never heard of a "flush" option. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Its for vfat and described at least partially at:

However it doesn't seem to be available in 10.2 via hal. Kay?
