the OS is XP home. When trying to attach a USB HDD the system just hangs and does not respond.
Also the SCSI/RAID host controller in Device Manager is marked with an exclamation mark.The same was the case with the CD/DVD drive too, but it was fixed after some search through the internet by deleting the filters from the registry.
I had installed Kaspersky Antivirus , when the blue screen appeared with the error: "Driver_IRQL not_less_than_or_equal_to..." i couldn't read the complete the message as the system shutdown. After this i removed Kaspersky and am using NOD32.
Tried a few system restores but nothing has worked out. Please provide some help , please.
I did check the USB HDD on another similar laptop it works fine there.
I have tried the other USB ports to but that too does not work. I ahve tested my USB HDDs on another system where the hdd IS DETECTED. I have tried rmeoving the USB devices and rebooting but the problem persists. Please help me out.
