Hello all,
I am still a novice in the world of digital photography. I got my first camera in Feburary, a Canon A70. My question is now that I have shot a ton of photos and I want to move them to CD I am running into problems. The first two CD-RW that I used, I lost about a third to a half of the availible space on the disk. In other words the capacity is 700MB and it says that there is only 400mb availible. Same thing with the next disk I tried, put one sets of pics on it, and now the disk size is 680mb, so I have already lost 20mb after copying one set of pictures. What am I doing wrong? Any help would be great.

| are you using a cd-r or a cd-rw??? my suggestion is to use a cd-r and wait until you have a full disk before burning. by leaving a session open or using a re-write it takes space on the cd to leave that session open. also what software are you using to burn??? |

Hi !
If you used a cd to keep your photos,it's better to use only cd-r, like that impossible to erase them by error.I prefer to have them in a second hard drive (120 GB), it's very easy to use (USB) and to organize the photos. |

I am using a hand me down computer with a whopping 6GB hard drive. So space is a premium. I was using the cd-rw so that I could burn to the disk when ever I needed to.I am still not sure on how to use a CD-R and keep the session open so that I can record more at a later date. I am using Roxio burning software, but I also have Ahead Nero, but don't know how to use it yet.

Hi,
I think the problem might not be with your burning technique (except for using an RW) but in how you are understanding it. let me try to explain:
1. after you burn say 20 photos of 1 MB each onto a 700 MB CDR, you will then have 680 MB left on that CD. If you did not close the session, then you can still burn 680 MB more of photos. If you closed the session then that CD is finished.
2. I would suggest that you save up at least 350 MB worth of photos (depends on how many MB's each photo is) before you burn them to a CD, rather than burning photo by photo. Too hard on the CD.
3. If you want to add more to the disc later (another 350 MB's of photos) do not close the session-- then you can come back later and burn that second 350 MB's. If you can hold out till you have accumulated 700 MB of photos (or close to it) then you can burn the CD and close the session. All the space will have been used up on the disc.
4. A CDRW is not so that you can continue to add and burn. It is so that you can erase and reburn. Thast is why we are suggesting that you do not use this type of disc--CD's can get corrupted and you could more easily lose everything on a reburned RW.
I hope this makes sense.

Don't finalize the burn if you do this you can't put anymore on the disc.
Always check the disk for readability before erasing off a harddrive.
I have very small harddrive so I have to burn a cd-r whenever I come back with pictures. It's not worth it to buy a new harddrive because I have a really old computer.

One addition to your nice summary ... each "session" required 25-30 MB of "overhead" -- data used to keep track of the files -- in addition to the data itself. With frequent sessions of smaller amounts of data, the total amount of actual data you can save is considerably less than the capacity of the disk.
A spindle of 100 TDK-brand CD-R is only $30-40 at Costco, or on sale at most places ... I just burn a month's worth to CD, regardless of data size.
A good strategy for using CD-RW is to save Save all of your photos to your hard drive, and copy to a CR-RW (your temporary backup). When you have enough to fill a CD (approximately...) burn either the folder or the CD-RW to a regular CD-R -- preferably 2 copies if you can afford it (keep one copy off-site!) -- then you can dump the data on the CD-RW and start over with the next batch of photos.
Whether you erase the photos from your hard drive depends on your level of data paranoia ... one of your best investments these days is a quality FireWire drive to keep everything on outside of your main computer, as a "backup" to the CDs. If you have access to a DVD-R, you can fit about 5-6 CD's worth of data to one DVD-R (TDK is US $30/spindle of 25 at Costco). |

| Also note that a "fully formatted" CD-RW disk has a data capacity of about 525MB -- the rest is taken up with the overhead needed to make it possible to continuously add files ... |

Be aware also that a CD-RW's are often not readable on a different computer than the one used to burn it. CD-R's, for the most part, are.

I have a couple of 4 or 6 gig harddrives kicking around if you want one to double up space. Let me know and I will send it to you. |

Both Roxio and Ahead Nero have options for whether or not to "close" the disc when you've written data but the disc is not full. Discs which are still "open" can typically only be read on the machine they're being recorded. Discs which have been closed can usually be read on any machine.
You can use either brand's software to make a direct-to-disc which you can just drag files to, like a big floppy disk. When it's full you'll have the option of "converting" it to a "regular" CD-R readable anywhere. These are not as reliable as the regular kind of CD-R, so only use it as a backup for files on your hard drive. If you want archival CDs so you can delete the files from the hard drive, burn them the "regular" way to high-quality media.
