Need help desperate!

Phone: Palm Treo 700wx wm5 ppc.

Created an sms message for a quick note of important data. Closed it and it says do you want to save? Yes. Ok saved my note. Later bring it back up, but decide not to do anything with it. Do you want to save? I say "no", figuring I might have edited it. However, wm5/outlook/sms then DELETES the message entirely. Crap.

I think the data may still be on the system somewhere. Either in TFAT or in cemail.vol. But cannot do crap with cemail.vol it's always in use by some process.

Is there any application that will do a low level search of the internal hard disk for a text string, like a hex disk editor?
