Identifying Blank CDs & Blank DVDs

Featured Replies

Tea break question.

 

Honestly, how many of you knew that a blank DVD is purple on the bottom and blank CDs are almost always green or a greeny-blue?

 

I've just had a colleague spend a few minutes trying to identify whether a pack of plain silver topped discs were blank CDs or DVDs, and was amazed to find that of the 15 or so people I asked in my office, non of them knew how to quickly tell.

 

Bearing in mind I work for a software company, most people here have been using blank discs for years.

 

I thought it was a pretty basic common knowledge fact that everyone knew?

 

 

Hmm I don't seem to be able to create a poll for this. I assume it's a Freedom only thing?

??? .....just look at the writing on either a DVD or CD....where it says what it is easy....simples!!! ....don't complicate stuff now!!! ;)

I used to work for a very large electronic retailer here in the uk who made a big thing of selling a setup with your laptop.

Buy a laptop and "techs" will know how to set it up...

Anyway it involved getting through the OOBE, installing AV/office and burning recovery disks.

Often I was the only tech in all day let alone all week so I started trying to train some of the other staff to do this whilst I battled dust bunnies and attempted to fix some truly horrible states of computers.

A large number of staff couldn't work out the "blank silver topped" DVDs and often put them in upside down causing the recovery media creation to fail - usually on disk 5 of 5.

Finally I gave up and started writing off the more expensive DVDs with the branding on them. Didn't help....

You mean some muppet makes them with NO writing on them so you know what they are...like speed or size?!!!

I know but then I've been doing this stuff for quite a long time now.

 

Won't be long before CDs go the way of floppy disks imho.

Sometimes printed on the clear centre bit where the spindle goes in tiny lettering.

Either that or you have to remember.

Christ I have got blank looking cd & dvds........

 

I bet they don't even know that if you look very carefully you can tell how "long" it is also (or how much has been written)

Ask them to spot which CD or DVDs are "double sided, double density"  :p

HAHAHA.................... :D .

 

 

that's too cruel...............

Or dvdram without a case/caddy.

I've got a simple LO tech solution. When I burn a CD/DVD, I use a proper pen to label the non written side.Then I know disc has something on it ,and more importantly , WHAT. SIMPLES, But ,then that's what formal practical engineering training teaches you :yawn:

See that's far too simple - you should be using lightscribe. ;)

 

I'm surprised they're still used much.  Since my work laptop was refreshed I don't have a single optical drive in the house, the only one I've got access to is in the car and unless SWMBO has used it it's never played a disk.

Not even as a drinks holder??

Maybe I should get one to raise some chicks like in the it crowd

I used to like the black blank CDs, and I remember getting some almost transparent purple ones too.

Ahh yes I used to burn PSX games onto black bottomed discs :)

I knew that, and I'm colour blind !!

 

That said I ain't seen silver topped ones for a long time.

 

As for getting them the right way up, there's a lip around the hole in the middle, this goes face down in the burner. 

Really stress them out.

 

Get them to identify DVD-R and DVD+R

Really stress them out.

 

Get them to identify DVD-R and DVD+R

or a DVD RAM disc

Or even BDXL.

Sometimes printed on the clear centre bit where the spindle goes in tiny lettering.

Either that or you have to remember.

 

If I remember correctly (which I may not...) there's a special media info block on each CD-R which identifies stuff like the manufacturer, batch, and maximum speed it can be burned at. So in a lot of cases, you didn't always need to care.
