How many times can I burn to a cdrw?

17 years ago

Is there a life span on cdrw's? I back up my pictures stored on my hd by burning them to cdrw's. Is there a life span on these rewritable cd's? I have never had problems before but I don't want to compromise the quality of data on a cd thats been re-written to multiple times.

Perhaps I'm being overly cautious?

Thanks.

From what I've found on this, they can be rewritten about 1000 times.

From my experience at work with both video and text a CD-R is much more reliable and stable than a CD-RW for long term storage. I am not sure why, but they are when archiving.

Also, as the repository of data we are finding we have to go to archive quality disks for long term storage rather than general use disks. This is said to be due to the chemical break down rate of the recording surface.

First, forget the pebbles or any other "stuff" in the pot bottoms. It doesn't help. Second, if you can safely remove the soil balls without them breaking up and messing up the root balls, you can safely repot the plants. If the root balls aren't sufficiently knit together so they don't break up, don't mess with them. It would be better to wait until the soil balls are sufficiently knit together so they come out whole, in one piece. If that's later this summer, do it later this summer. If it doesn't happen by late winter, early spring, when you would be planting bare roots anyway, wait until that time and repot them. If they break up and put the roses at risk because of the disturbance, at least it is the appropriate time of year for them to experience that disturbance. Good luck! Kim

How many times can you install a toilet?

Also, just as a warning, be careful with how you store the toilet during the remodel. I stored my nearly-new (3 or 4 year old -- newest in the house) toilet while I was remodeling the bathroom. When I went to reinstall, the side of the bowl was broken. I would recommend storing it upright and perhaps wrapped with bubble wrap or something to keep it protected in case it is knocked over.

iTunes says formatted CD-RW not blank?
Q

The Sonic package has a program called DLA (Direct Letter Access). It formats the disc for drag-and-drop use of the disc like a big floppy. Look for that as it comes standard. Try looking here.. - Click the Start button - Double-click on the My Computer icon - In the My Computer window, right-click on the CD device then choose Properties - On the CD Drive Properties screen, click on the DLA tab, then add the checkmark to Enable DLA on your drives - Click the OK button, then restart computer

Yikes. DW how many times can you move them?
Q

A lot would depend on how far and what kind of terrain it would be moved on. I have worked in the past on DWs that have been moved several times with no major damage. What i did find, if the two halves are not sealed up good with plastic the blown in insulation will all end up in one end. Also the plastic wrap underneath needs sealed good or it will tear further at highway speeds. Never found any structural damage.

There is much debate on the longevity of both CD-R's and CD-RW's. The technology of burning a CD-RW is not magnetic, like a hard drive, but based on melting a dye layer, and re-melting it each time you burn to it. My opinion is that, if you are re-melting this layer many times, eventually some areas may degrade and affect your data/pictures. For stuff that's important to me, like pictures, I burn once to a CD-R. I think it's false economy to keep re-using rewritable discs, given how cheap discs are.

IMHO, CDRW's are a joke. Even quality CDR's are so cheap bought in bulk that I simply abandoned CDRW's long ago in their favor. Every computer-friend I have has come to the same conclusion and do the same. If your information is important, use quality CDR's.

Thanks for the responses.

I use compucessory brand cdrw's are they any good? Been using them for a couple of years. Otherwise for cdr's I use the cheap hp blues.
It just seems such a waste to me to chuck a cd that had backup data on it. Thats all.

Thanks
