Hi all,
I'm running FC2 with 2.6.8-1.521 kernel.
I try to use a 160 GB external hard drive in a Enermax EHD-350 USB 2.0 box. When I plug the HD in, I see this in /var/log/messages :
Sep 13 13:34:59 localhost kernel: usb 1-5: new high speed USB device using address 5

Sep 13 13:35:02 localhost udev[5071]: creating device node '/udev/sda1'
Then, I mount the drive with:
mount /dev/sda1 /mnt/usbstorage
All seems ok when I ls /mnt/usbstorage but when I try to copy a big file (700 MB) from internal HD to usb HD, the usb one gets stuck after a few seconds and cp fails with the error message "cp: writing `/mnt/usbstorage/my_big_file': Input/output error".
The access LED remains lit on the usb drive and /var/log/messages says:

...
After that, I unplug the usb HD, plug it in again but nothing happens (no message in /var/log/messages). To be detected, the usb HD must be powered down and powered up again.
The usb drive works fine on a window$ box.
If my problem has already been described, please forward me to the right place.
thx for help
