When i connect the usb connector of my external hard drive i get a blue stop screen with the following message:

stop: 0x00000050 (0xE3853030, 0x00000000, 0xBFF7F335, 0x000000001)
ADDRESS BFF7F335 base at BFF6F000, DATE STAMP 3edd1027-PQV2I.sys
Beginning dump of physical memory
Physical memory dump complete. Contact your system administrator or technical support group.

This happens when I boot with it connected as well as connecting the usb when it has already booted up.

I can't find away to access the external hard drive at all. Have tried going into device manager and scan for hardware changes still no change.

Works in other machines

Can anyone help please


Thanks

What OS are you running & which service packs?
Do other USB devices work OK on that system?

Forgot to ask, are you running Symantec Protector software?
Also, what make is the USB drive caddy?

Hi Samm

the op system is 2000 pro
service pack 4
not running symantec protector software
all other USB devices work
all i can find on the caddy is "external subsystem"

thanks

have just run system mechanic and have had access to the ext drive ,but when I rebooted the same problem was back again.

[Samm]

Are you running any Symantec, Norton or Powerquest software?

Also can you tell me :
have installed any drivers for the USB drive yet?
what USB version (ie v1.1 or v2) does your system have?
what chipset (Intel, Via etc) is the motherboard? (check in device manager for this if you don't already know)

in the device manager make sure there are no question marks as well

have a question mark on other devices - unknown device

[s.charlton1]

sorry forgot to add using usb 2

[s.charlton1]

have just tried
device manager- right click universal seriel bus controllers - click check for hardware changes

ext drive came back on
but on reboot back to same problem

[Samm]

If you remove the USB drive & boot up, does the 'unknown device' disappear from device manager?

[Supergeek.dcse]

is the drive useing the power from the port or it s own power pack

[s.charlton1]

unknown device there all the time
drive is connected by its own power pack
