Re: [Freedos-user] Chkdsk
Granted others may have helped, but I simply want to make sure you are using a freedos tool on a drive that is running freedos? meaning that drive was formatted with freedos, not ms dos? If not one reason for the error is that you should not use chkdsk from one edition of dos on another. By which I mean use freedos tools on freedos drives, and ms DOS tools on ms DOS drives. If that is not the situation, ignore me.

Re: [Freedos-user] chkdsk for fat32!
Hi Sparky, > Hey will the chkdsk for fat32 ever be made? ^^; It already exists as (a bit old) dosfstools port: http://www.freedos.org/software/?prog=dosfsck If you want dosfsck to either "look like chkdsk" or "work on 8086 and 80286" then please have a look at earlier threads about the issue: Looks do not have a priority but feel free to fork a chkdsk-style version if you think otherwise ;-) Dosfsck for 8086 would have serious performance issues because FAT32 are large data structures, also FAT32 disks often have many files and dirs while FAT16 allows only up to 64k files or dirs. A subset of the dosfsck features MIGHT work with suitable modifications in algorithms and memory management at reasonable speed on 8086. However, as far as I remember earlier discussions (please look them up in the freedos-user list archive), many nice and useful checks are either lost when only 1M RAM is available or become horribly slow. If the topic REALLY interests you, please start a NEW thread by citing the list of checks and their 8086 viability based on a summary of old threads.

If the target is genuine XT hardware, I'm not surprised if a more recent CHKDSK will fail to run. Among other reasons, it's likely compiled to run on 386 CPUs, and simply won't execute on anything earlier. The XT CPU is an 8088, which, like the 8086 from which it is derived, is a 16 bit CPU. The difference between them is the 8088 has an 8 bit IO bus path (an IBM cost reduction misfeature incorporated into the XT), while the 8086 has 16 bit. The NEC V20 is a functional clone of the 8088 intended to be run at higher clock speeds, and with claimed greater internal efficiency. None AFAIK can possibly run 32 bit software. http://en.wikipedia.org/wiki/List_of_Intel_microprocessors#The_16-bit_processors:_MCS-86_family Correct. The V20 featured improved microcode, and could actually execute 80186 instructions. I had an app or two back when compiled for a 286 CPU that would run on the V20. Reports back then gave the V20 about 5% better performance than the 8088 at the same clock rate, and it was a drop-in replacement, so it was a cheap speed up. I also had an AST 6-Pak card with a meg of additional RAM. AST supplied software let me use the RAM as a disk cache and a RAMdisk. My startup created a 512KB RAMdisk, and copied several most used utilities to it, and made the ramdisk first in my PATH, and I defined TEMP and TMP to point to it, for the benefit of things like PKZIP that could be told where to create temp files.. I also had a 256K disk cache. I had a freeware app that could take unused video memory and allocate it to DOS. The Hercules card left 64K free, so DOS saw a 702K system. The rest was seen as EMS memory, and reserved for things that could use it. It sped things up a treat. __ Dennis https://plus.google.com/u/0/105128793974319004519 -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

The difference between them is the 8088 has an 8 bit IO bus path (an IBM cost reduction misfeature incorporated into the XT), while the 8086 has 16 bit. The NEC V20 is a functional clone of the 8088 intended to be run at higher clock speeds, and with claimed greater internal efficiency. None AFAIK can possibly run 32 bit software. http://en.wikipedia.org/wiki/List_of_Intel_microprocessors#The_16-bit_processors:_MCS-86_family Correct. The V20 featured improved microcode, and could actually execute 80186 instructions. I had an app or two back when compiled for a 286 CPU that would run on the V20. Reports back then gave the V20 about 5% better performance than the 8088 at the same clock rate, and it was a drop-in replacement, so it was a cheap speed up. I also had an AST 6-Pak card with a meg of additional RAM. AST supplied software let me use the RAM as a disk cache and a RAMdisk. My startup created a 512KB RAMdisk, and copied several most used utilities to it, and made the ramdisk first in my PATH, and I defined TEMP and TMP to point to it, for the benefit of things like PKZIP that could be told where to create temp files.. I also had a 256K disk cache. I had a freeware app that could take unused video memory and allocate it to DOS. The Hercules card left 64K free, so DOS saw a 702K system. The rest was seen as EMS memory, and reserved for things that could use it. It sped things up a treat. __ Dennis https://plus.google.com/u/0/105128793974319004519 -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

Re: [Freedos-user] chkdsk for fat32!
Hi Sparky, Why dosn't chkdsk support fat 32 yet? i have an IBM XT that had FAT32 DRIVES AND i cannot check them for errors i have to pull it out and check them on my newer machines ! Because chkdsk aims to be very much like the DOS version, so it has to run with very little RAM and 16 bit CPU etc. And indeed your problem was on IBM XT, so you could not run DOSFSCK on it. Still impressive that you can plug a drive big enough to make FAT32 worthwhile into that XT. Maybe an early 8 or 16 bit ISA IDE controller with BIOS extension to support 500 MB, 8 GB or even 128 GB disks? Eric PS: It surprises me that even current Ubuntu does not let you run DOSFSCK interactively with any sort of GUI. Some friend recently had issues with his FAT32 USB disk and I had to teach him how to run DOSFSCK in a terminal to fix. -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

Re: [Freedos-user] CHKDSK on floppy
Hi Ray, This is CHKDSK beta 0.9.1 If there is a sub-directory present on a floppy, CHKDSK report seems normal. If there is no sub-directory - whether or not there are files: Assertion failed: size, file bitfield.c, line 34 Abnormal program termination Is this to be expected? No. I remember that this bug already was discussed years ago. I would assume that we also found a fix back then. Maybe somebody remembers / can check? Alain? Imre...?

Re: [Freedos-user] Chkdsk
Hi Ray, Norton Disk Doctor from W2K says C: is OK. FreeDOS chkdsk c: produces a 40K file. All entries are: file has an invalid size. The only chkdsk bug I find is 1954. The problem stated in 1954 does not appear here. Let me guess: The size is exactly 4 gb minus the actual size of the file rounded up to a multiple of the cluster size? Several other people have experienced this, but it is believed that the current version no longer has the described problem. Which version did you use? And can you test if the current version really works better? www.freedos.org/cgi-bin/lsm.cgi?mode=lsmlsm=base/chkdsk.lsm Thanks a lot!
