hdd badblock and burn dvd

[sonicmario]

If a rar, zip or exe file is good in a good sector of the HDD and that sector becomes bad (badblock) then these files are corrupted and burned on DVD discs as if they were non-corrupted files? I use ImgBurn, BurnAware Free and Ashampoo Free

You should get a read error when such a sector is read from.

I did not understand

Man, you have to done some tests with those drives to really know what is going on and if files are really corrupted.
It will be easy to know if rar/zip are corrupted just by testing them.
But difficult to guarantee integrity of exe/rom. (you have to success starting them at least...)

Those very old drives have normally access to the "Read Long" option that can eventually help you at recomposing a bad sector...

Here is how I see the reallocation procedure:
- sector become bad by reading it. (his computed ECC does not correspond to the stored ECC)
- this bad sector become a pending sector. (that you cannot read)
- drive will retry and retry to read it to the infinite while it does not fall to the right computed ECC.
- if success right reading it and sector is not in so bad state, drive will re-use this sector maybe with some rewrite, and free it from pending.
- if success right reading it and sector is in bad state, drive will realloc this sector while copying the data on the reallocated sector.
- if no success, and depending of the sector read response structure, drive will throw it reallocated without can copy your data.

So who know if your drive succeeded to restore your data from a bad sector...
I suggest you firstly to try finding those corrupted files.

Is ECC the protection that prevents files that are stored in bad sectors badblocks (downloaded in these sectors or good sector that became bad sector) from being normally written to DVD discs?

ImgBurn will write what it can read from the drive, normally it will alert you if cannot read as said by Arch Stanton, but it can also shutoff the error and write zero instead alerting you. (who know...)
You can eventually full read your drive with Victoria to be sure that all sectors can be read, but do not do it if your drive is in very bad state!

[sonicmario]

In that case what happens with zip, rar and exe files in bad sector badblock try to burn to DVD?

[diybit]

Who know!?
Maybe the good data was burn, or maybe the bad if it was from a very defective sector that cannot be reallocated with his good data...
So you have to test your files to be sure of integrity.

[sonicmario]

files in bad sectors of the HDD (badblock) can be burned on DVD?

[Arch Stanton]

Depends on the software you used. If software tries to read the file using normal API it will be notified of an error. Usually software will then notify user and say "I can't continue blablabla". A tool like Unstoppable copier gets the same API error but decides, I'll live with the error, and will just continue reading file and tell user, okay I got the file but with some errors. In general burning software that's not specifically designed for it will read source file and if that results in an error will probably give up with an error.

So yes, you can if you want read a file that occupies a bad sector. And yes there will probably be issues with that file. Then it depends on the file you were copying what consequences are. For example you may not be able to open the file you copied because since one sector was bad checksum now fails, an archive file perhaps. A JPEG may look like like example depending on what the tool used to copy the file did to deal with the bad sector.

So files that are in bad sectors badblocks will be burned to DVD? there is no protection to avoid burning that ignores badblocks sector errors and file corruption is present in badblock bad sector?

godammit i give up

godammit i give up

[diybit]

yes if your DVD clean from bad sectors (badblock)

[HaQue]

How many blocks would a bad block block block, if a bad block block could block blocks?

[Arch Stanton]

How many blocks would a bad block block block, if a bad block block could block blocks?

I'll have what he's having, thanks

If the zip, rar and exe files are located in the badblock defective sector or in a part of the badblock defective sector, what will be shown during DVD burning? I used Ashampoo free, burnaware fre, imgburn free programs

[DRUG]

Dude.

Consider your file is made of: AAAA
If the 3rd A is a bad sector, you wont image it, or burn it, or whatever you wanna do. So you will end up with a new file made of: AA0A.

You cant bring that A back of the sector is bad. File probably won't work. That's it. If you buy a 100 page book and when you read it it only has 95 pages, you won't know the full story, right?

What block from that block from badblock to that block through that block? WHOoAT BLOCK!? (HDD badblock)

I doubt pausing the burn is possible so you will get badblock.
