The observation that the message about copying original/backup results from FAT32 having 2 boot sectors (also 2 copies of the FAT?) makes good sense to me, and I did copy the original to backup when I got DOSFSCK working without error.
It is an alarming and puzzling message though, and I imagine that in further developments of FreeDOS CHKDSK will add smooth FAT32 ability, or else the partition/format tools will be changed to write to both copies of the boot sector so that DOSFSCK doesn't generate such a message. The error messages (malloc: general problems + Aborting) went away and the tool operated smoothly when I boosted the memory on this machine from 16 to 24MB. Thanks for the clues, Eric. By the way, do we have a FAT32-supporting defrag tool in the FreeDOS 1.0 distro? (It would be interesting and thorough to test whether the memory requirement and errors are related to CWSDPMI vs. HXRT DPMI, but I just don't have time now! Perhaps such a question also touches on the memory issues I raised with Bolitaire and FreeDOOM -- and also Kraptor, by the way, but I'm not pursuing that one on account of an additional mouse-speed issue -- but again, I need to content myself for the time being with just finding a decent workable solution.) --John Hupp ----- Original Message ----- From: Eric Auer To: freedos-user@lists.sourceforge.net Sent: Thursday, September 28, 2006 6:42 AM Subject: Re: [Freedos-user] DOSFSCK issue > This concerns a pure FreeDOS machine (Pentium 120, 16MB) having a 4.3GB > hard > drive with a single FAT32 partition created by the CD Installer's > partition > and format tools after the drive had been zero-filled. > > Running DOSFSCK -N C: generates a screen of 5 columns, each "row-field" > entry being of a format like ", 504:20/00" and then under that set of > columnar data: > Not automatically fixing this This is probably the "boot sector differs from backup boot sector" list-of-differences. Maybe DOSFSCK could display this in a more compact form. The background is that FreeDOS SYS only writes the boot sector, but not the backup copy of the boot sector which exists only on FAT32, so the backup boot sector differs from the boot sector. > malloc: general problems > Aborting That is strange. Maybe 16 MB are not enough? Did you try with real CWSDPMI instead of the renamed HXRT DPMI? Use CWSPARAM to disable the use of swapfiles, if possible. > Running DOSFSCK -R C: generates the same screen of data followed by: > 1) Copy original to backup > 2) Copy backup to original > 3) No action > ? _ > Entering 3 results in: Given the above explanation, you can guess that "no action" is okay but that "copy original to backup" would also be good. > malloc: general problems > Aborting See above...
