Crash when doing a "Delayed Wite Failed"

[Cheb Bowles]

I am using Forensics Tool Kit to index a 120GB HD.
After about 3 days (needs 5 days according to Access Data),
the operation fails and I get the "Delayed Write FAilure
ALL DATA Lost."

I am using the following setup, an hp Laptop, an USB HD
drive containing the HD being indexed. The Date/Index info
is being written to a second HD using Firewire connection.

I have crashed 3 times since about June 4.

I have tried the above on a Sony, with 1GB.

Any Help would be greatly appreciated; this is delaying a
Forensics Examination of the HD.

Thanks,
Cheb Bowles
