Hi, I've been getting different results from the file system checking programs CHKDSK, DOSFSCK, DEFRAG from FreeDOS, as well as MS-SCANDISK.
This is happening in two hard disks: Hard disk Type Computer Processor ----------------- -------- ------------- ------------------ Quantum 402 MB FAT16 Asus 486-DX2 66 MHz Toshiba 2167 MB FAT16 LBA ThinkPad 380Z Pentium II 300 MHz (In practice, both disks seem to work just fine.) Both disks have been recently repartitioned and reformatted with FreeDOS FDISK and FORMAT. Interestingly, FDISK gives an error message at the end indicating that partitioning failed for some reason (sorry, I do not remember the error message). However, after endless repetitions of the whole procedure, I realized that partitioning was being done, in spite of the error message, so I proceeded to format and use the disks. My FDISK.INI file was adjusted as per instructions from Eric Auer; it includes these two important lines: ALLOW_4GB_FAT16 FALSE VERSION W95 Now to the results. CHKDSK (beta 0.9.2, year 2009) will abandon checking after just a few seconds, giving messages such as: \INSTRUC\SOFTWARE is a directory without '..' \INSTRUC\PORTATIL is a directory without '..' \M\??8??AAT.A?W is a directory without '..' \M doesn't contain an '.' as first entry Error accessing the volume Furthermore, DEFRAG (1.3.2, year 2009) gives the message: Disk corrupted, cannot defragment! However, DOSFSCK (2.11.DOS3, 8 Aug 2007) will run happily and detect no errors, ending with a message such as: Checking for unused clusters. C:: 15832 files, 39014/51377 clusters Heap usage: 0 bytes in 0 blocks, peak: 1242024 bytes, 18398 blocks The command line was: dosfsck.exe -l -v -V -r C: -l list path names -v verbose mode -V perform a verification pass -r interactively repair the file system I also tried MS-SCANDISK. It took a long time to run, found hundreds of errors to correct, pretty much destroyed all files and folders, and the hard disk had to be reformatted. Summing up, it seems that we have two different issues here: 1. Why does FreeDOS FDISK give an error message indicating that partitioning failed? 2. Why do FreeDOS CHKDSK and DEFRAG (as well as MS-SCANDISK) report so many errors while DOSFSCK does not, and in practice the disks seem to work well?
