I installed an ext. USB HDD. formatted, mounted and all seems to be OK.
but...if I try i.e. to copy a large amount of data the process hang (after
about 150 Mb segmentation fault) and if I want to restore the mount point I
need to restart the system.

Gentoo
Kernel 6.0.5

any Idea?

thanks,
stefano

Reminds me of how my USB disk acted when my graphics card came unseated.
The point being, it's possible you have a hardware issue somewhere. It
may not even be obvious.

Linux has a history of standing on the shoulders of giants, while Microsoft has
a history of trying to break giants' legs. The latter is quite less efficient.

There are some issues with USB-IDE bridge chips. I have two USB external
cases. One works perfectly both ways and one reads perfectly, but writes
with errors. Not to mention, under Windoze they both work OK, but this is
probably a matter of adopting hardware to non-standard-conformant drivers
of Win...

Go and check http://www.qbik.ch/usb/devices/index.php , which is a fine
Linux-USB compatibility database. I shop USB devices with this list (since
the faulty USB case) and it never let me down.

Just open the case and enter bridge's chip ID into the DB. If someone found
any quirks, there might be a solution there.

Hope it helps,
