I have Win XP SP2 and I recently installed a Netgear SC101 which uses "Z-San" drivers, I believe they are SCSI drivers.

On three of the four laptops at home, I can create, attach and view drives, but on one laptop the create/attach process hangs.

When I check Computer Mgmt / Device List I see a generic name for the new driver under the Disks section. If I "update driver" it will correct the name and then my create/attach process will appear to succeed.

However, there will be no drive letter. I can then manually assign a drive letter via the Disk Management option in the Computer Mgmt utility, after which I can see the drive from any program I run when I do a "File/Save As". However Windows Explorer CANNOT see this drive.

There are a couple of symptoms here that will hopefully help me to troubleshoot this:

1) Why can any program I run see the drive in the"File-Save" dialogue, but Windows Explorer cannot?

2) If I reboot the PC, the drive letter will disappear. I can reassign it via Computer Mgmt, but after every reboot the drive disappears.

3) Any idea why the attach/create process is hanging? The Netgear utility's log file tells me it's waiting for "disk initialization", which I assume is related to the device driver not updating itself. Any ideas on where I can look to investigate why this driver isn't getting updated? Is there an incorrect path somewhere? Or a corrupted file? Or a service that should or shouldn't be running?

One helpful thing here is that I have working laptops, so I can compare them to the non-working one. I have already compared binary files for various drivers and explorer.exe, but they are all the same binary-wise. I have also compared services running -- no effect. I have turned off all startup items via MSCONFIG and disabled windows firewall -- still no effect. But if you have suggestions on other things I can compare, I will do that.

Thanks. John
