The maximum theoretical limit of USB 2.0 is 480mb/sec; which
is
60MB/sec, which would (again, theoretically) translate to
11.66
seconds for said 700mb file. In actual use, it's going to
be a
few times longer than that, but still should be faster than
6-8
minutes.
Does your friend's PC have the EXACT SAME external device,
as
in did he try YOURS? If not, could be something wrong with
your external HD.
Have you checked your BIOS to be sure USB 2.0 is enabled?
It's
not always by default. On many mobo's you have to [enable]
USB
2.0 or "Hi-speed USB". Otherwise they will
operate at USB 1.1
which is only 12mb/sec. Some mobo's have a "Legacy
USB" entry
and you try and toggle it. Enabling that can sometimes
cause
problems, but note that if it's disabled some old USB
devices
may not work.
Are you sure you have XP SP1 installed?
"THE SERVICE DATABASE IS LOCKED" sounds like it
means a needed
XP Service is either disabled or taking to long to start.
You
should find more info that here:

CKED%22&btnG=Search&lr=lang_en
Note that many of the CD's that come with these controller
cards are screwed up. Even in the rare event they Autoplay,
they'll tell you no drivers are found on the CD, or other
odd
things. Many times you have to manually browse the CD for
your
correct specific folder for the controller card's chipset
(the
CD's have many on them), and your OS, then install the
driver
files manually via the Device Manager's "yellow
mark" for the
PCI device.

hi...my computer is two years old and has the usual bells
and
whistles...i'm using win xp pro...the computer has usb2.0
but
i'm not getting usb2.0 speeds...when i transfer a 700mb avi
file from the computer to a usb external hard drive it takes
6-8 minutes to complete the transfer(it takes a matter of
seconds on a friends computer)...it takes about the same
amount
of time to go back from the external to the computer...i
inserted the Cd that came with the computer so as to install
the
usb2.0 drivers and was told "the latest SiS USB2.0
driver
included in service pack 1 has already been installed on
your
system,please rescan for hardware changes in device
manager(which i did)...to try to resolve the issue i decided
to
install a usb2.0 PCI card...i tried two different cards and
got
the following message when installing both "Cannot
install
this hardware.There was a problem installing this hardware
Universal Serial Bus (USB) Controller.An error occured
during
the installation of this device.THE SERVICE DATABASE IS
LOCKED"
...now i'm not exactly a rookie with using a computer but
this
alert is completely new to me...does anyone know what this
means,what could cause it,and exactly what i have to do to
resolve the problem...like how does a person UNLOCK the
service
database...i assume if this could be done that the usb2.0
speeds would be restored and i wouldnt have need for the
usb2.0
pci card...i may also ask if a format and reinstall of
windows
would solve the problem...any help would be most
welcome...thanks a bunch...Gary.
