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: http://www.google.com/search?hl=en&lr=lang_en&newwindow=1&safe=off&as_qdr=all&q=USB+2.0+PCI+controller+card+%22THE+SERVICE+DATABASE+IS+LOCKED%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. -Clint God Bless Clint Hamilton, Owner http://OrpheusComputing.com http://ComputersCustomBuilt.com ----- Original Message ----- From: "Gary Burke" 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. ============= PCWorks Mailing List ================= Don't see your post?
