[Recovery] Ability to skip recovery of corrupted files. |
|
A lot of files are worthless once corrupted by a
bad sector example JPG or MPEG files. so once a
sector is unreadable attempting to recover the other
sectors in the file is a waste of CD drive life.
I would propose a setting for either number of bad
(totaly unreadable) sectors or Percentage of bad sectors
to be found per file before the remainder of the
file is skipped and so noted either in log file or
a place holder file in the recovery directory.

Also alow for some sort of multipass. The first time through, it makes only one attempt at reading each sector, and gives a list of successes and failures. If the user desides that is "good enough" then its done. Otherwise operator can request it to try again to recover some more files using one or more attempts at each sector. This way the user can decide how good is "good enough" and how much effort he wants to put into recovering a few hard or impossible to read files.

Hi
I have a Video CD that some of data in 4th minute of it are lost!
So I cant neither copy that CD nor watch that part.
Now I want at least copy it.
Please help me if you can.

I too like the multipass idea. I would make one other suggestion that concerns the output file options (specifically the "don't re-write the output file if filesize matches"). My suggestion is to also allow the option of re-write the output file if CRC matches"). Supposing I have two CD's that are both copies of the same program, each containing bad sectors. If I had the power to re-write the "recover" output file, depending on a matching CRC (instead of filesize), I could use a second disk copy to recover parts that are missing from one disk but are available on the second. The combined output(s) will written out to the "recovery" output file allowing a better recovery.

Woops..maybe this will make better sense
I too like the multipass idea. I would make one other suggestion that concerns the output file options (specifically the "don't re-write the output file if filesize matches" option box). My suggestion is to install a second option box to allow re-write of a discrepant file in the "recovery" output file if the CRC of the file in the "recovery" output file does not match the current file on the current CD. Supposing I have two CD's that are both copies of the same program, each containing differing bad sectors. If I had the power to overwrite a discrepant file within the "recover" output file (made by one CD copy), depending on a matching CRC (instead of filesize), I could use a second disk copy to recover files to the "recovery" output file that are missing from first disk but are available on the second. The combined output(s) could be written out to the "recovery" output file allowing a better recovery.

I think the ability to manually skip a file and continue with the next is a valuable feature, if not downright essential. I tried to recover a CD containing a large having-problems file (spent massive amounts of time doing this), and aborting the recovery just tossed me out of the whole thing.
Do we get two wishes per item? Hope so.
I also think that a way to specify specific files to recover is important, or at least a starting file.

I like what ksmith120 said about the recovery process. Sometimes I just want certain files to be recovered. So if there were an option to skip the bad or corrupt ones and get the files that are ok, would be great. Then later when convient for me, I could let my computer try to recover the bad sections.

I love the multipass idea.
