Technical Information and Troubleshooting

Actually, if a file has been deleted, chances that the records would be found are small. To greatly increase the

chances to recover deleted files successfully , you may actively use scanning with enabled Known Files Types.

Note: All above is correct for intentionally deleted files. In case of a corrupted file system, HFS/HFS+ can be

recovered quite successfully.

When recovering files with HFS+-specific attributes (resource fork, finder info, etc.), R-Studio saves it in the

so-called AppleDouble format. When they are copied to an HFS+ disk under Mac OS X, those attributes will

be automatically restored.

4.6 Bad Sectors

Quite often, drives from which the data are to be recovered have bad sectors, or those sectors that are very

hard, even impossible, to read, mostly due to hardware problems. R-Studio tries to read such sectors several

times. The number of tries is specified either on the Settings/Bad Sectors dialog box, or on the Properties tab,

the Drive Control section, for each drive separately.

When R-Studio encounters such bad sectors while performing various tasks and they appear unreadable, it

treats them as follows:

Object images:

R-Studio fills the space in the image file where the bad sectors should be with the pattern specified in the Pattern

to fill bad blocks field on the Settings/Bad Sectors dialog box. Please note that R-Studio writes the pattern on

the image, not on the source drive.

Files

If Skip files with bad sectors on the Recovery dialog box is cleared, R-Studio fills bad sectors in the recovered

file with the pattern specified on the the Settings/Bad Sectors dialog box. Information about such files will

appear in the Log.

If Skip files with bad sectors on the Recovery dialog box is selected, R-Studio skips files with bad sectors and

displays their list on the Files with bad sectors dialog box when the recovery has been completed. You may

select files to immediately recover them or to mark for later recovery. You may also save this list to a text file.
