Something returned an unrecoverable I/O error back from a mount call.
Do you have a driver installed somewhere in here? If it is a file
system filter driver, look at your mount handling. If it is a disk
filter, look at your read/write IRP handling logic. You are definitely
doing something wrong.
If all else fails, set a breakpoint in IopMountVolume and walk through
the mount code until you find where the error is first returned.
Of course, you won’t get a dump in a situation like this - the drive
hasn’t mounted far enough for the OS to figure out where to write the
crash dump!

Subject: [ntfsd] Bugcheck-0xED UNMOUNTABLE_BOOT_VOLUME
Hi FS gurus,
First of all, I state I’m not a FS driver developer but I was
just wondering something happened on One of my XP box and how to recover
it.
When I boot my system (xpsp1/i386), I got a BSOD
bccode:
0xed (UNMOUNTABLE_BOOT_VOLUME)
0x82554af8, <– device object of the boot volume
0xc0000006, <– STATUS_IN_PAGE_ERROR
0,
0
It seems crashing before kernel debugger can attach. It doesn’t
seem to generate a dump file (I have the full mem dump enabled). I want
to know what may cause this problem and how to recover it.
Thanks,
Calvin
