cd rws finalising before disc is full


jacdor

Question

I am using cd rws to act as backup for my digital photos. I thought that I would be able to add to the disk until it was full. But this is not the case and so I am getting a large collection of cds with only a few images on each. How can I keep adding to the cd until it has reached capacity. :

Make sure that when you hit burn and the options page comes up that you uncheck "read only disc" before you burn.This will allow multi session discs.

Also when you go to add data you need to import the previous sessions.

thank you for much apprieciated help as I now have got write and read only sorted ...I hope.

I am confused as to what you mean, and how to, import previous sessions surely these sessions are already on the disc. Sorry I think dementia has set in early???

The difference between CD-R and CD-RW is that CD-Rs have the pits and lands (the optical equivilant of magnetic 0s and 1s) created by "cooking" a dye, which is fairly stable; and CD-RW have the pits and lands created by melting and recrystalizing an aluminum alloy - which promptly starts to de-crystalize.

 

There is no hard-and-fast time frame in which the data will fade beyond the point it can be recovered, but the newer (less expensive) alloy that has been used for the last several years fades out a lot faster than older (usually 1-4x) CD-RWs. Generally you have months, but it can be days, weeks, or years. If formatted for Packet-Writing, it will disappear faster.

 

I would suggest you are NOT "backing up" your digital photos on CD-RW. You are merely putting them somewhere where one day you will put the disc in the drive and learn why you shouldn't have used CD-RW.

 

Once you have learned that the hard way, as I did, you will subsequently use CD-R for backups.

What this does is bring forward the TOC (Table of Contents) so you can still access those files. it merely keeps the address so you can find the document.

 

You said earlier "I am using cd rws to act as backup for my digital photos" .

Don't use CD-RWs for long term storage, use R's.
