During extraction of data from an image file, a CD, DVD. HD, Flash drive etc. one can get errors. It's not what you want ... but it can happen. In case of an image file the reason is mostly that the data seems so garbled that no sensible data can be derived anymore, or when the end of the file is reached. In case of hard media it's the drive that returned an error. In that case NO data was returned.
If an errors occurs, IsoBuster offers several options, depending on the way how the extraction is done.
This Error Message can occur when you're extracting files and folders. It offers you the choice to RETRY reading the sector, IGNORE the sector (no substituting data will be written for the missing sector) or to QUIT extracting altogether. The option 'Ignore All' will make sure you're not prompted again during extraction and all erroneous sectors will be omitted. Depending on the situation you may need to renew the 'Ignore All' request when multiple objects are selected for extraction.
This Error Message can occur when you're extracting data (from various media or an image file) to an image file, but only the user data portion. It offers you to RETRY reading the sector, apply an option from the SELECTION window or to QUIT. The possible selections are :
OMMIT data which means no substituting data will be written for the erroneous sector (this is the least likely option you would need),
REPLACE with all zeroes which means the sector size will be written but containing zeroes only,
REPLACE with dummy data which means the sector size will be written with data different from zeroes.
The selection making most sense will be selected by default. Click the check box 'Always apply selection' when you do not want to be prompted again during extraction. Depending on the situation you may need to renew this request when multiple objects are selected for extraction.
This Error Message can occur when you're extracting data to an image file, from CD and raw. It offers you to RETRY reading the sector, apply an option from the SELECTION window or to QUIT. The possible selections are :
OMMIT data which means no substituting data will be written for the erroneous sector (this is the least likely option you would need),
REPLACE with all zeroes which means the sector size will be written but containing zeroes only,
REPLACE with user data all zeroes means that the replaced raw block will contain raw data completely according to the CD standard (sync bytes, header, sub headers, EDC/ECC etc.) but with User data containing all zeroes.
REPLACE with erroneous sector means that the replaced raw block will NOT contain raw data according to the CD standard so that a copy tool will recreate the errors (e.g. some programs require errors on the CD).
The selection making most sense will be selected by default. Click the check box 'Always apply selection' when you do not want to be prompted again during extraction. Depending on the situation you may need to renew this request when multiple objects are selected for extraction.
