Wanted: Feedback from service people - esp computer techs

[Catty1]

OK.

I dealt with a client in April or May. During the job, I used a program to retrieve as many photos as possible from her HD.
Having to do that was due to an error on my part, but I did recover a couple of hundred photos, some of them the personal ones she wanted.

Last week - around July 1st - she contacted me because a guy in the IT department where she works had said he could 'get all her photos', for a crazy fee of course.

I don't happen to still have her old hard drive. How long do you hang on to such things, tech people? Should I still have it in case?

Thanks.
