She is currently travelling, and phoned from Japan (where it is about 1 a.m. and she has had to relinquish the pc she borrowed earlier this evening).
I can try Staz's suggestion when she comes back to the UK (I too have an old Inspiron which probably uses the same software).
Stuartli's comments are more worrying, since they could indicate there is something wrong with the CD she used for backing up. I was more inclined to replace her laptop than try to get a replacement HD from Dell - unless that had proved the only way to try to read the CDs.
