I added a new tool to amitools, my set of cross platform classic Amiga tools: xdfscan!

What does this tool do?

Its a disk image file scanner that inspects Amiga disk (.adf) or hard disk (.hdf) image files for AmigaOS OFS or FFS file systems. If such a file system is found then the scanner runs a validator that does an in-depth check of the whole file system structure. If anything does not match or does not fulfill the file system specification then error or warning messages are generated. Warnings are usually not critical and the files on the image are all accessible, but error messages may hint to file corruption in the image. In the latter case it is advisable to recover the image by running a xdftool repack command or by issuing a DiskSalv running on an emulator.

This tool either scans a single disk image file or scans through a full directory tree. The latter operation allows you to quickly scan your disk image collection with a single run…

Have fun scanning your disk collections for corrupt or even broken images… (I must admit that the scanner is really picky and it found some issues on images I believed that were running Ok for years on a real machine… So don’t panic if lots of warnings or errors are reported… AmigaOS is quite robust handling these disks without reporting trouble…)
