HP USB DAT72 driver/yellow exclamation can't clear
Posted on 2011-03-13
I have a HP DAT72 C7438A drive. Was working properly, all of a suddent it is not.
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
I'm running XP Pro all updates and service packs.
I've tried reinstalling and updating the drivers. Manually and via HP's driver update utilities. I still get the yellow exclamation in device manager and can't get it to "take" When I disconnect the drive from the motherboard I ge tthe familiar USB donk sound and if I plug it back in I get either the normal single "donk" or the unhappy USB "double low Donk" sound. I've uninstalled and rebooted, etc, tried all the obvious (to me) stuff.
I Connected it to a different PC, installed the same drivers, and the drive workes fine. Something is hosed in my XP's USB system I am afraid. I also tried moving it to a different USB port on the motherboard, no luck.
Anyone know how to fix? Maybe how to completely erase it from the system as if it was never there so it can start "clean". I knwo how to find and delete the driver I think, USB is another story.
