Hi,
I am trying to use RegisterDeviceNotification to detect hot-swappable
sata drive surprise removals/insertions in a box of disks (service
context on xp and 2003). The only notifications I can get are usb
related, in the case where I specify
DEVICE_NOTIFY_ALL_INTERFACE_CLASSES. The disks in question are raw
disks that we manage ourselves.
I am aware of the distinction between class and interface GUIDs as
discussed on Doran’s blog post at:
http://blogs.msdn.com/doronh/archive/2006/02/15/532679.aspx.
(Isn’t the usb example at
http://msdn.microsoft.com/en-us/library/aa363432.aspx broken since it
uses GUID_DEVCLASS_WCEUSB? That example doesn’t work for me.)
The sata card vendor suggested I should be able to get drive remove/add
notifications, when using the scsi adapter guid specified in their .inf
file, but I believe that is also a class GUID.
Should I be able to do this? Would it require special driver support?
My vendor suggested it shouldn’t, that it was all handled by an upper
level. Maybe I should try DBT_DEVTYP_HANDLE and specify a disk handle
instead of a guid?
Any hint would be greatly appreciated.
Thanks,

Have you tried registering for GUID_DEVINTERFACE_DISK or GUID_DEVINTERFACE_VOLUME and seeing what you get notified on? certainly registering for interface notification arrivals will work that way. You should get removals as well, but you might need to open a handle on arrival and then register for notificatiosn on the handle to be told of surprise removal.

If your “raw disks” show up in Device Manager as disks, you should be
able to use GUID_DEVINTERFACE_DISK. Yes, you will get notified of any
other hot-pluggable disks showing up as well, and you’ll need to figure
out if the notification you got is for a disk you are interested in.
