Re: EWF-RAM protected partition on Compact Flash becomes unbootable



1. Are you using FAT32 or NTFS on the CF drive?
2. If data is being writen to the second partition when the system shutdown, it is very possible that data could get corrupted.
3. Also, the CF card changes could be a problem, you might want to test another manufacturer.

Hello,

I have been running a small (115MB) XPe(SP1) build for 5 years
on a SimpleTech 256MB CF that reports itself as a fixed drive.
Over these 5 years I have gone from a rock solid startup to an
increasingly suspect boot process. My users are experiencing
more non-recoverable BSOD at bootup including Registry File
failures. The only fix at this point is to overnight them a
new customized Compact Flash.

I am protecting the C: partition with a RAM based EWF and I have
left the D: partition unprotected and available for the main
application, data files associated with the application and an
application error log file. A third area on the CF has been
allocated for the EWF. The only way to powerdown this embedded
system is to 'slam' the power off!

1st goal...return to that robust system I once had that can
reliably survive shutdowns. How is my EWF protected partition
getting compromised? Is this a problem with my CF? I have been
using the same CF, although its internal controller has changed 3
times! On occasion, important directories on the unprotected D:
partition get trashed. When I attempt to browse to them, the OS
asks me if I would like to format the disk.

2nd goal...when an OS failure occurs what is the quickest way to get
my customer up and running? Can I switch to a larger CF and create a
dual boot system on the CF and switch to the 'copy'?

.
