But you've calimed they are more relible, there's as yet not enough evidence to claim that.

nospam

Whisky-dave
Wrong.

those are defects. anything can have a defect.

try dropping a hard drive and ssd and see which ones still have data.

put both under water and see which ones will still have data.

Whisky-dave
Are you also saying tehre's no differnce between teh 'Entreprise' models and the standard most people buy ?

nospam
nobody said there isn't.

however, hard drives are going to fail quite a bit sooner than ssd. it's basic physics.

however, they are far more reliable. period.

Whisky-dave
you've not heard of DVD cleaners ? Shows you how little you know about the subject.

nospam
cd/dvd cleaners are a complete waste of money.

Whisky-dave
they work I've used them.

nospam
lots of people have used them. however, they are a complete utter waste of money.

Whisky-dave
it's not just where the light is focused either, it's about light dispertion too. Even putting as label on a disc can cause problems.

nospam
only if you put the label on the wrong side.

the scratches would need to be very serious to cause a problem. minor scratches do not matter at all.

Whisky-dave
There's is a tolerance to what you might call minor scratches. But how can you know so little about this. There's plenty of tips out there for fixign damaged discs due to scratches I've used them myself.

http://electronics.howstuffworks.com/how-to-fix-scratched-dvd.htm

"As a DVD stores its data externally on a disc it can easily get scratched, which can affect the data. Scratches are a disc's worst enemy. Whether or not a scratched disc can be repaired depends on where the scratch is located. If the scratch is on the top, shiny part of the disc, the disc is not repairable and all the data is lost. If the scratch is on the bottom, plastic part of the disc, you may be able to repair the disc by resurfacing and polishing it "

nospam
minor scratches do not matter at all. you have to gouge it to cause a problem.

Whisky-dave
So what do *you* mean by lost data ? or are you goign to claim dtat doesn;t get lost.

nospam
data is not lost like keys in a couch. that's just crazy talk.

Whisky-dave
and you don't loss data it becomes corrupted and that is what people say they have lost data.

nospam
try using the term like everyone else does for a change.

if you have the data on the main drive you don't need a backup, do you?

Whisky-dave
No you don't need backups until the original fails or disapears for whatever reason.

nospam
at which point it will be too late to make a backup.

you have to make the backups *before* a problem occurs.

Whisky-dave
Then the first option is usaully to find the backup, or an archive depending how you work.

nospam
if you can't find your backup, you have much bigger problems.

the thing is you don't know when (not if) the main drive will fail, nor can you prevent accidental deletion, which is why backups are vital.

Whisky-dave
One of the reasons. I don;t think 'accidental deletion' is so much of a problem with HDDs not sure about SSDs due to there much smaller capacitices poele might start deleting files like they used to with floppies and low capacity HDs. That's down to the indivual.

nospam
accidental deletion is always a problem. people make mistakes.

if the user accidentally deletes a file, it's not going to end up there.

Whisky-dave
Who said anyhting about the user deleting it, that's not the only way files and data gets removed.

nospam
files don't delete themselves.

Whisky-dave
The file does, this is real basic stuff here you're missing. https://uk.answers.yahoo.com/question/index?qid=20071206121022AAyP6wD

"When you delete a file, it's never actually deleted unless the facilities are available on the computer system to command the file system to actually overwrite the contents of the file. When a file is deleted, all that happens is that an entry to the file is removed so you can't see it when browsing for files and it won't turn up on searches. It'll likely still be there on the disk however. "

nospam
that's what i said.

the blocks that had the data may still have the data

Whisky-dave
So they data isn;'t lost then is it.

nospam
it's inaccessible, which means it's lost.

but they are marked as unused and may be overwritten at any time. there is no file anymore.

Whisky-dave
The data is still there. That is how recovery programs work not by magic or spells or chants but by looking at the data and retriving it. As time goes buy the space that the file took will be overwritten if and when needed.

nospam
it's not a file anymore and unless you recover *before* it gets overwritten, and with a modern system, that can be as short as seconds and it's *gone*.
