"disk read error"

[Gary Brooke]

We've used a large number of different compact flash cards for building our
images under XPe, and we've been unable to boot our image using the latest
extreme IV. We have set up the CF card using fdisk and format using the /S
parameter. When this is done, the CF card does indeed successfully boot.
However, after bootprep is complete we only receive the "disk read error"
message. This same method has been used with many other sandisk cards
without any difficulty over the past year. We have used fdisk /mbr on the
target CF card, as well as attempted an NTFS file system using format D:
/FS:NTFS on the target machine.

KM mentioned a MBR fix tool a few posts back. The tool might be on the
xpefiles.com site.

Just so that you know not all CFs are created equal - even from the same
manufacturer.

Gary,

You may want to read through this thread:
http://groups.google.com/group/microsoft.public.windowsxp.embedded/msg/0df820e48a79ec72?hl=en&

And the MbrFix tool can be downloaded from here: http://www.sysint.no/Nedlasting/MbrFix.htm.

I have a Sandisk fixed 5000 which wouldn't boot. I downloaded and ran the
MbrFix tool.

When I ran mbrfix with the fixmbr command, it didn't resolve the boot
problem. However, I ran mbrfix with a Transcend CF of the same size (which
does boot) ok and saved the MBR to a file (savembr command). Then I used the
mbrfix restorembr command to restore that MBR to the Sandisk 5000.

I then booted into FBA and ran thru that successfully. Checked the EWF and
that was successfully created. Haven't done any testing yet with my app but
so far, the Sandisk is working fine.

Re my previous post on resolving the boot problem with the Sandisk 5000,
after using it for a few hours I've had no problems. Just be sure to reformat
the partition to be used for XPe right after doing the MBR transfer and
before putting on the pre FBA image.
