Title: Drive access notification
Post by: John on March 07, 2006, 03:18:22 AM

I wasn't sure where I should put this so my apologies if it is in the wrong place.

Does anyone know how to detect when a specific drive is being read from or written to? Like when the light on the case starts lighting up.

I'd like to develop a program that sits in the system tray and blinks at the same time the led on the case does. The reason is that the case is not always in the same location as the keyboard and monitor and I like to visually see when the drive is active. I assume I'll need some type of windows hook but I'm not really sure where to start.

Any pointers in the right direction would be appreciated.

HDD as ATA/SCSI devices has own port-map to access to, as minimum you need to reach the 0-ring to read them and to find out if the device is in busy state (it transacts). write a driver for 0-ring... i cant say any more sensable

John,

A few weeks ago I wrote a backup program using FindFirstChangeNotification. I just wrote a new one using ReadDirectoryChangesW, which gives access to all changes due to:

Code Select

	FILE_NOTIFY_CHANGE_SECURITY
	FILE_NOTIFY_CHANGE_CREATION
	FILE_NOTIFY_CHANGE_LAST_ACCESS
	FILE_NOTIFY_CHANGE_LAST_WRITE
	FILE_NOTIFY_CHANGE_SIZE
	FILE_NOTIFY_CHANGE_DIR_NAME
	FILE_NOTIFY_CHANGE_FILE_NAME

The attached program changes the Title Bar Text with the old fashioned rotating cursor :dance:

The program is in FASM syntax, but should be easy to follow.

hth,

John,

Glad to help!

When you get your--blinking in the system tray--version working, post it here!!

It might be a while as I'm just starting to get back into learning ASM after a few months break. I'll be sure to post it here though if/when I get it going.

Thanks again for your help :)
