Permanent file deletion - sensitive data

Thanks Shelf-Life,
That seemed way too easy, but I tried it out and it appears to work. I have a feeling that PCI standards won't accept that as adequate enough though.
PCI - for those of you unfamiliar with it - is a Visa/MasterCard set of rules to protect credit card account numbers from theft. So while the solution offered does work, I need to be assured that the data could not be recovered by anyone (except for the NSA of course
). Any more ideas to throw into the fray?
Thanks,
Pete

pcitweak - read/write PCI config space SYNOPSIS
pcitweak -l pcitweak -r PCI-ID [-b|-h] offset pcitweak -w PCI-ID [-b|-h] offset value DESCRIPTION
Pcitweak is a utility that can be used to examine or change registers in the PCI configuration space. On most platfoms pcitweak can only be run by the root user. OPTIONS
-l Probe the PCI buses and print a line for each detected device. Each line contains the bus location (bus:device:function), chip vendor/device, card (subsystem) vendor/card, revision, class and header type. All values printed are in hexadecimal. -r PCI-ID Read the PCI configuration space register at offset for the PCI device at bus location PCI-ID. PCI-ID should be given in the form bus:device:function, with each value in hexadecimal. By default, a 32-bit register is read. -w PCI-ID Write value to the PCI configuration space register at offset for the PCI device at bus location PCI-ID. PCI-ID should be given in the form bus:device:function, with each value in hexadecimal. By default, a 32-bit register is written. -b Read or write an 8-bit value (byte). -h Read or write a 16-bit value (halfword). SEE ALSO
