Did newfs on those partition and made things worsen -- restore =
completely fails:
(I had experienced another similar problem on an IDE, which works well =
for 6.4 and 7.2, but 8.0.)
This dirve works fine under FreeBSD 6.4.
Is something new in 8.0 making disk partition schema changed?

Subject: 8.0-RC3 USB lock up on mounting two partitions from one USB =
drive
=20
When mounting two partitions from a USB dirve, it can cause the drive =
access lock up for a long time.
Details:
Terminal 1 --
term1# mount /dev/da0s3d /mnt
term1# cd /mnt ; rm -fr *
when rm starts, go to terminal 2 and do:
term2# mount /dev/da0s3e /dist ### this will hanging for a long time and =
USB hard drive activity light is off.
After more than 1-2 minutes, mount returns, and the drive activity light =
is blinking, thus removing is going on.
term2# ls /dist ### this will cause dUSB dirve hanging again -- no =
avtivity.
Similarly, ls will finish in a couple of miniutes or longer, the rm =
command continues; but for a while, the drive
activity will stop again.
Reboot machine, repeat the above steps, and result will be the same. =
Reboot machine again, and just mount one
partition, then doing "rm -rf *" without involve the second partition, =
rm will finish quickly.
Has anyone obseved this behave on 8.0-RC?
