Please ask in microsoft.public.windowsxp.hardware

To access a dead microdrive in raw mode... I'm afraid, you need a plier and
a small screwdriver.

No "raw mode" in USBSTOR - the spec is there on www.usb.org, you can read it.

Also - if the device does not appear in Device Manager - then sorry, it is
dead.

Then, how you format it (if it is not formatted or erased)?

As of now I am not willing to format - Pavel may be right,
how do I format ?
The device has no drive letter.

There is no "chckdsk" on this device when it is plugged in and
I reboot.

After doing and USB analyse I can tell more:

The device does a lot of handshake an return "OK" until it
comes to passing on information of the file system on it.
Then there is an error code x'C000009C'.
This seems to be a bad sector.

There are tools to read sectors for every device. How about
an USB device ?

So everything boils down to 3 questions:

1. How do I force the OS to assing a drive letter to the device

2. Which tool do I use to read on a sector level basis or from a
physical device

3. How do I force the OS to do a CHKDSK on the device ?

Admin-wise: DSKPROBE
Developer-wise: CreateFile on \\.\PhysicalDrive%d (i.e. 0, 1 and so on).
