There should be no difference in dragging a folder vs dragging individual files. To answer your questions more directly.ĭVD when appropriate precautions are taken, can be an appropriate media, however there are many caveats. Or it may be that you have a bum dvd reader. Quality of blank dvd's can vary quite a bit. You do not need to do the whole process twice, just the final burn from iso twice to get two copies. You'll have to look up how to do that with your software. iso disc image first and then burning and finalizing that image to the dvd. When Burning, I've found much better success making an. Mark only in the center area of the disk.- Do not put label stickers on your disks.- Don't print with inkjet printers.- Immediately store your disks in a way that protects them from scratches.- Protect disks from UV light, excessive heat and humidity as well as frequent changes in temperature.- Validate the data on the disks from time to time.Peter Krogh advises to use the DVD+R format, but states that manufacturing defects and poor storage conditions can result in data loss.He recommends two brands of DVD that are considered particularly stable: Delkin Gold and Taiyo Yuden.And of course: a single burned DVD should not be your only backup of your valuable photographs. Phil,A quote from the excellent second edition (may-2009) of The Dam Book, the bible for archiving digital photographs:'With proper handling, a quality optical disk that is burned well should be a valuable backup to a hard drive-based archive for 5 to 10 years'.The author Peter Krogh gives the next tips:- Use quality disks- Burn at slow speeds- Don't use a solvent-based pen to mark the disk. Look at your process and identify any errors you might be creating yourself. I use "disc at once" writing to maximize compatibility between computers and operating systems. I burn hundreds of DVDs every year, and have no difficulty reading them afterward, even years afterward. Unfortunately, this process is usually proprietary and requires special software to extract the data. Packet writing is used to emulate the operation and convenience of HDDs and floppy discs on CDs and DVDs. It's good practice to "verify" after every burn, which compares files read from the disc to the originals, or between CRC check sums. There are other fatal problems too - bad discs and writing speed too high, for example. Since DVD's hold so much data (it seems like a lot if you don't take digital pictures), burning programs like Roxio and Nero allow an open-ended data structure, often as the default. This terminates the data area and locks in the directory. The operating system can't read a DVD (or CD) unless the disc is properly finallized. I've spent many hours and wasted a number of DVDs trying to solve this. What should be a simple task is driving me nuts. So, is DVD-R an appropriate media for this? Should I use DVD-RW or something else? Can I drag entire folders to the DVD or do I need to drag each individual file? And yes, I do have a CD/DVD RW drive. Just for grins I clicked to format the DVD as Mastered, and I got a message stating that the DVD was write protected. I can tell that something has been written to the DVD because the bottom surface of the DVD has a band that is colored differently from the rest of the surface.īut when I check the DVD by putting back in the drive (as if I was going to pull files from it) Windows apparently thinks the DVD is blank because it displays the prompt to format the DVD, just like it did when I first loaded the fresh DVD. The process completes normally and the system ejects the DVD. I'm then prompted to select a format - I select Mastered - then drag the folders to the DVD. So far, I tried both Roxio and Vista's DVD burn utility, with the same result: When I put the DVD back in the drive to verify the files are there, the files are not recognized or there not there at all.Įither with Roxio or Windows, I start by putting a fresh DVD-R in the drive. My computer runs Vista, and it came with Roxio "Easy Media Creator 9". I've been trying to copy a number of folders containing jpeg, tiff and raw images to a DVD-R for archive purposes without any success.
