I am having a problem with my portable USB HD (3.5"). I want to backup some
data onto it, but get an error. I have two PCs, both running XP Home SP3, and
a laptop running Vista SP1. The one PC (call it PC 1) and my laptop recognise
the drive perfectly and the External HD reads and writes perfectly.
The second PC Call it PC 2) will not load the driver and gives the error
message "USB device not recognised
One of the USB devices attached to this computer has malfunctioned, and
windows does not recognise it. For assistance in solving this problem, click
this message" after plugging in the HD. Clicking on the message then shows
the "Unknown Device" in the device manager list (USB Controllers). There is
no item under Disk drives other than my two internal HDDs.
The HDD is a 320GB 3.5†in Seagate external case. It is powered by a
separate powers supply.
I tried to update the “unknown device†driver in device manager by pointing
it to browse the system32 folder, but it does not locate the file. I have
checked on PC 1, and it indicates that it uses the driver USBSTOR.sys. This
file is located in the same system32\drivers folder (same version) on PC 2.
I have tried the following to resolve the problem:
1. I am using the same power supply to the HD (external power) and the same
USB cable to ensure there are no problems there.
2. I am using a USB mouse and keyboard (wireless) and my USB flash drive
works perfectly on PC 2, so I suspect there are no problems with the ports.
3. I have tried plugging into different (including front and rear) ports
with no luck.
4. PC 2 is running 2 internal HDs (with three partitions – C (system), D
(files) on one drive, & G (music) on the second). I renamed the music drive G
instead of F as I read that may be a problem) – no help.
5. I have plugged in a new flash drive and a 2.5†external HDD, both were
recognised and worked perfectly.
6. I disconnected the second internal drive to see if that was causing any
conflict, and that did not help.
I am now at a loss. PLEASE can some one give me some suggestions here?
