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

When a spot on a hard drive starts to go bad, the data there is moved to a new location and the old location marked as bad so it will not be used again. If the spot is so bad though that the data cannot be read though, an error is often displayed and something like CHKDSK will need to be run to see if it can solve the problem. If it cannot though the data is gone. (And that is one of the very reasons Backups are so important).

If your backup program was set to, or if it simply ignores errors, then what was written to your backup is potentially corrupt.

When you run your backup, use its "verify" option to check and see if what was written to the backup is the same as what is on the hard drive.

If you have already done the backup, you could now do a file by file comparison to see if what is on the backup exactly matches what is on the hard drive.

:confused: There is no way to know for sure without checking.

1) No, it is not perfect. For example: The data was located in an area on a platter where damage was so great the data could no longer be read.

2) The idea was started by IBM in 1992.

3) Depends on the drive manufacturer; they came on board over several years.

Please read S.M.A.R.T. - Wikipedia for more info.

1) Which function within SMART technology is responsible for automatically relocating and isolating defective sectors of the HDD (badblock)?

2) IBM had the idea of SMART in 1992 but in what year did SMART technology arrive on HDDs from Seagate and Western Digital?

3) What does ECC and G-List mean? is this part of SMART technology and is it within SMART?

1) Exactly how probably depends on the drive manufacturer, and it has probably changed over the years.

2) Don't really remember when those two started advertising that they were now using S.M.A.R.T.

3) a. ECC is Error Correcting Code: Error correction code - Wikipedia
... b. AFAIK (As Far As I Know" G List is a celebrity you have to Google to find out who they are.
... c. ECC, probably some form of it is used in S.M.A.R.T. G-List, no.

between ECC and G-List which one is associated with the relocation and isolation of defective sectors of the HDD?

If there are a couple of Bad Sectors, then Check Disk or SMART can move the data to a good sector near by. But if there are more then a couple, if there are several, a Bad Cluster, or Bad Block then the data on that area of the HDD is corrupted and not able to be moved to good sectors and the data cannot be recovered by DIY processes, the drive needs to be replaced.

There is no "Automatic" relocation of data on Bad Sectors. SMART will alert you when Bad Sectors start appearing with a bad sector count, letting you know, and/or if the drive is about to fail. it does not "Fix" Them.
When you run Check Disk (ie) from an Elevated Command Prompt type C:\chkdsk /R and press Enter. or other Disk Diagnostic software, It will scan your drive sector by sector and if it finds one or two bad sectors, it will "Fix" it. It will try and Move the data off of that Bad sector to another Good sector nearby then marks that sector as Bad and it tells Windows to not store any data on the sector. Once you start seeing Bad Sectors, it is time to replace the drive, just like Cancer, the bad sectors will increase as the Drive ages. A drive that is 20 years old probably has many bad sectors, though even drives that are a few months old may have Bad Sectors too.

This is the same question you originally asked. This has been answered a couple of times now in this thread. Please read through your thread, if there is something you don't understand then type a different question that hasn't already been answered.
