Corruption in Compact Flash even when using EWF

[sudhi_rangarao]

Hi,

I am facing some issues with my flash drive getting corrupted inspite
of using EWF. Details are below. Appreciate any help in resolving
this....

Background....
-----------------------------------------------------
OS Windows XP embedded SP1.
IDE 250MB Flash drive with two primary NTFS compressed partitions.
Partition C: 120M "RO" via the EWF RAM overlay
Partition D: 126M "RW"
Partition <45>: ranges from 256K, 1008K 3000K
Remainder Free:

The OS was developed based on a 128M drive but Ghost has been used to
resize the partitions larger.
The system does not have a battery backup and power can be removed
unexpectedly.

Part of the application is logging data (circular logger) :
2M file on USB 2.0 thumb drive FAT (the motherboard is USB 1.1)
written 1/sec
2M file on the D partition written 1/sec
500K file on the D partition written in bursts but much less
often than 1/sec.

Symptoms.............
---------------------------------------------------------
IDE Flash Drive failures:
Corrupt MBR/partition (incorrect sizes, start and stop values,
EWF partition sometimes missing)
Corrupt partition D
Corrupt files (recoverable with chkdsk /f)
MFT corruption in particular MFT mirror

System failures .........
-------------------------------------------------------------
Non Mountable Drive
Dies in 2nd line of check disk
Check disk indicates the drive is "RAW"


Thanks
Sudhi

Hi Sudhi,

Any luck solving this one. I have exactly the same problem. Details
are

OS: Windows XP embedded SP2.
IDE Flash Drive 4GB with two primary FAT32 partitions.
Partition C: 512MB "RO" via the EWF RAM overlay
Partition D: 3.5GB "RW"

Files are transferred to the PC via FTP onto the D partition. It seems
to run ok for a while but it seems that once the D drive is full the
PC blue screens and everything is corrupt. Missing HAL.DLL comes up on
the blue screen on any following reboots.
