Trying to recall where a checksum setting is

Once in XP I came across a setting that allowed the data copied or written to
be "checked" or verified something like that in some general preference box.
Even at the risk of slowing down any copying function, I would prefer this.

Can any one help me with this--sorry to be so vague...

1) I was trying to remember where it was
2) I wondered how it was performing the parity check--but I guess it was
doing checksums of some type

Thanks for reading

Thinking of CRC, Cyclic Redundancy Check? There are applications that
provide this additional feature, such as disk-imaging software.

You may be thinking of the "Verify" option of the COPY command (COPY X Y
/V).

A better techinque is the COMPARE command after finishing the copy (COMP
Xfile Yfile).

Not sure WHAT it did, but there was a checkbox SOMEWHERE in XP during one of
my setups--I'll find it if I have to reenact the 3 Stooges as plumbers.
I remember years ago that all computers sold to government contractors and
military-related desktops had to have 9-bit--as opposed to standard 8-bit,
RAM installed, the last bit being used for parity checking (over my head a
bit, but I get the concept). This was chiefly to prevent bad data in the
delivered files that the gov paid for.
I recall RAM companies selling them in either 8- or 9-bit versions when they
listed their ads.
Back to my magic button: if I can locate that, I will research it on MS to
find out precisely what it does and post back. What I'm ultimately looking
to do is keep the direcotry and copying function stable without the system's
nodes and indexes getting whacky. If you control that, you could run XP for
another 10 years. I hope so.
