I'm in the middle of salvaging what potentially could have been a disaster. I've been archiving my RAW files to DVD for the last couple of years - its alarming how many DVD's I've simply archived and forgotten about ... filed under- "'when I get round to it". I've upgraded my computer since last year and until recently I haven't touched the archive. I once had a problem with an unbranded disk that became unreadable soon after it was burned and - other than test data integrity at the time of burning I rarely look at them until they are needed - once I've got over the initial flush of enthusiasm for a new set of pictures they are forgotten about. In a way Flickr acts as a snapshot of what I've done. Recently I needed an archived disk because I needed recover a RAW file to create a picture for printing. Since I had the failure of the unbranded disk I decided that 'economy' disks should not be trusted. So I always bought known label branded disks like Imation, TDK and Maxell. I have avoided buying the double sided disks because they are expensive and I don't like the idea of trusting 8GB worth of images to one disk so the single sided 4.5 GB disks suited just fine - its like a damage limitation exercise. However, when I tried to read the (Maxell) disk it failed on CRC error..which means the data volume did not match that on the DVD checksum on the volume header .... in English, there was unreadable data on the disk so the reader said no to everything !!
After a week of serious stress I finally managed to recover the data because when I built my new dual core PC I kept all the parts of the old computer - including the DVD burner that created much of my archive. The disk copied ok if a little slowly with the burner that created the disk - I managed to retrieve the files and copy them over the wireless network to my new PC.

As a result of this I decided that I could no longer trust DVD ( thankyou for the warning Manfred!) and find another way of archiving my huge collection of RAW files.

My new PC has 1 terrabyte of RAID1 striped SATA300 drives and I have an external 350 gigabyte IDE drive, plus, now the old PC is back up and running another 200GB of space on there too....

Unfortunately, over 1.5 terrabytes is not enough capacity to house my archive of RAW files so I'm looking at buying another high capacity external drive of at least another terrabyte of SATA300 power and maybe more.

So most people I'm sure would think .... problem solved - but not me !...

Hard Drives are much more reliable than they were 15 years ago. One of the most sickening sounds I remember from the late 80's was the sound of a hard drive screaming as the r/w heads failed and crashed into the spinning disks - closely followed by flames if you were not quick enough to shut it down. Even so, trusting a mechanical device to backup is asking for trouble. Hard drive technology, like all other PC technology is moving quickly and who's to know what the motherboard/disk controller interface/ Hard Drive standards will be in 10 years...

...how do you back up your archive ?

...will the disks be readable in 10 years ?

... is there an answer to the thorny issue of archiving digital data ?

The camera manufacturers , camera and DV salesmen are keen to sell you the technology but are without exception unconcerned about how the buyer backs up his digital data on a 'your problem not mine' basis !

Oh... and this picture is one I pulled off the recovered DVD - if I had thrown the old burner away, this image would have been effectively lost, Data Recovery Services are notoriously VERY expensive.

I think I should spread this picture around Flickr to act as a reminder to ALL digital photographers and digital artists.... so any suggestions for suitable group candidates would be appreciated












Day 123 - Computer problems




Day 123 - Computer problems





Our cat, Michael knocked over a glass of water and it spilled all over my laptop...

For 5 days I've been having problems with my computer. It wont start, when it does.. It wont log onto my wireless network and then automatically just shuts off after 10 minutes.

It's frustrating, I feel so disconnected. Unable to check my E-mail, surf the web or upload any pics into Flickr.

This afternoon I managed to get my computer to work again.

But for how long?

I went ahead and uploaded my pictures from the last few days. So I'm up to date with my 365 days project. You can click back to view them.

But it looks like I'm going to have to start saving up for a new laptop..

This one (named Charlie) has been with me for nearly 3 years.

So If I disappear again, it's due to technical difficulties.

But I'm working on it.

I hope everyone is having a good week.

Day 123 of 365 days
