From: David J. Craig on 31 Aug 2005 00:30 No. No. No. File Systems mount in the following order: Funny ones, Microsoft ones, RAW File System. File Systems only mount to volumes. It is a physical drive mounted as a physical drive. No RAW anything. Just a physical drive that consists of sector zero to N - 1. Try WinHex. Very good. Simple and easy to use. Some useful templates to interpret certain sectors. You can write your own templates for other sectors as you need.

From: Frank L. on 31 Aug 2005 03:10 Looks interesting, yet it does not work. The device does not get mounted. Therefore no letter is assigned to it. DSKPROBE works in two ways: 1. Opening by drive letter No letter, no opening possible 2. Opening by physical device I do not see the physical device, therefore I can't open it The device is not dead, otherwise handshaking would not occur and actually end up with SUCCESFUL. It is the READ of the data, which fails. Not to forget how the issue came up: I tried to copy 136 M onto the device and got a "Write delay failed" message. Then I unplugged the device which caused the message "You have unplugged without stopping the device" or such. What happened here ? Some sectors were written onto the device but the file system was not updated eventually. To me there is a mismatch between the file system and the actual data on the device. Is there a flag like the "dirty flag" on the NTFS ?? The questions remains: - How do I access a device which I do not see nowhere - Can't I force W2K to do a CHKDSK at boot time Frank "Maxim S.

From: Maxim S.

The USB interface is not dead, but the microdrive inside probably is. --PA "Frank L." <FrankL(a)discussions.microsoft.com> wrote in message news:ED5D1542-65BF-4926-912B-72506B29ADD5(a)microsoft.com... > > Looks interesting, yet it does not work. > > The device does not get mounted.
