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
