Read only files

How do I save files from "My Documents" to a Cd and avoid "Read ONly"?

Most CD's are readonly (not sure how CDRW's fit in).

But I'd copy those files to my harddrive. Then use windows explorer and select
them. Rightclick on the group, choose properties and turn off the readonly
property.

It's usually best to open the files from your harddrive (or network drive). Bad
things can happen if you open from removable media.

Except, for some reason, Zip discs.
Use them all the time.
Just keep under 50% capacity.

Hi Bob,
You definitely do not want to open Excel files from any removeable
media, so you've definitely learned something not to do.
More infomation on my
http://www.mvps.org/dmcritchie/excel/backup.htm#removeable
The most notorious for loss of files are diskettes, and I think zip drives
would have to be next in line.

Even so, if you copy from the CD to your hard drive you will still have
the read-only bit set on, and you will have to turn it off on your hard
drive. You can use the DOS utility XCOPY or some other programs
like XXCOPY to copy to your CD for backup that do not turn on the
read only bit. There are other applications that will copy to a CD without
setting the read-only bit. To reset the read-only bit

http://www.mvps.org/dmcritchie/excel/backup.htm#readonly

In a DOS Command Window of the directory (on your hard drive) enter:
attrib -r -s -h -a *.*
to reset read-only, hidden, and archive bits in current directory or to reset
only read-only files in the current directory and subdirectories just enter:
attrib -r /s

True David, that you have a heck of a lot more exposure and contact with the
XL world then I, but from personnel experience, and I don't own any Iomega
stock, I've yet to have any problems with Zip discs.

Keeping the disc at 50% or lower capacity, only because of what I've learned
here, about XL's write properties, and starting out with the 100 meg and now
the 750 meg discs, I have a manufacturing plant and 3 offices using them,
all without any mishap for the last 3½ years. And the entire manufacturing
operation is XL driven.

Do you know of any actual reports of problems with them?
If you do, I don't suppose that you would happen to be aware of how close to
capacity their use might have been.

lookup up click-of-death in Google web search.

Learned about that from someone giving a talk of data recovery
from broken hard drives. And many people in our computer club
had apparently been affected by that directly or indirectly. Never
understood why someone would want to buy a zip drive once writeable
CD drives were available with a lot more storage and a lot less cost
for the media.

 

[RagDyer]

Well David, now you've scared me with those links.

I've never heard of this "Click of Death" before, and with 18 Zip drives,
varying between the 3 sizes, it makes one wonder.

I did notice that there were a great many links pertaining to Macs.

However, *No* problems whatever in 3½ years must say something.
I just hope that my organization remains among the "silent *majority*", as
I'm sure that, like me, people not having a problem are *not* going to post
to the internet, while the others can be *very vociferous*.

As to your last question, it can simply be stated as "unbelievably convent",
for transporting, usability, re-usability, and universally readable between
all machines.

[David McRitchie]

I use a CD writer to backup my files. If I had a DVD writer you can believe
that is what I would be using instead. I mentioned my backup page much
earlier in the thread: http://www.mvps.org/dmcritchie/excel/backup.htm
I use XCOPY command to copy files, which does not set the read only bit.

I never had a zip drive, I looked at the cost of the media and the amount of
storage. CD's were $1 at the time, not almost free like today (unless
you forget to send in your rebate form). In fact both of the CD writers
that I've purchase were external, which was nice because when my
desktop computer broke I simply continued with the laptop and the
external CD writer.

I'd never looked up "click of death" on the intenet before, from what I'd
heard you get a click and the zip drive is toast. From one of the three
articles I actually read it said --- don't use any disk from a drive that was clicked.

 

[RagDyer]

Actually, we use a double backup procedure.
Three servers (LANs) are utilized throughout the organization, which is the
main reason that Zips were started in the first place (transporting between
LANs), due to the absence of a WAN.

One machine is designated per department to backup individual department
data from the server to their C:\ drive.
And this machine backs up onto Zips.
These Zips are the ones used for transporting between LANs, so in reality,
they're read every second day.

This fragmentation of data and backups, while not the ideal procedure, does
provide a heck of a lot of redundancy, and safety.

But it seems that this thread has really gone off on a tangent from the OP's
question in particular, and the pertinance to this NG in general.

The idea I wanted to interject into Dave P.'s post was the ability of the
Zip (as removable media) to handle XL files (not just copy), where perhaps
other forms might have failed, as long as the Zip was utilized at <=50%
capacity.
