![]() ![]() Thus ScanDisk will ignore volume labels with data (which usually indicates that they are really files whose volume attribute has been set incorrectly), whereas CHKDSK treat the corresponding clusters as unlinked and recover the data. ScanDisk and CHKDSK deal with attribute corruption somewhat differently.It copes with directories containing more than 32,767 entries, unlike CHKDSK.With CHKDSK, this involved using a disk editor (as documented by Microsoft!). ![]() It can repair invalid media descriptors.Sector recovery previously involved using the RECOVER tool. As its name indicates, ScanDisk can scan the disk surface, as well as verify the file system’s integrity it will repair files stored on bad sectors (as far as it can - the data stored on the unreadable sectors won’t be recovered), and it can also flag sectors which take too long to read (which may indicate they’re about to become unreadable).files which end up pointing (entirely or partially) at the same cluster chain - this always involves data loss, but it’s better than CHKDSK which would only tell the user about the problem (users then had to copy the files manually and delete the originals). ScanDisk can “repair” cross-linked files, i.e.So, my questions for anyone who would like to help is:1: DO you know of another DOS program that will defrag a fat-32 disk?2: Do you have any other suggestions for me such as "Don't defrag you fool.you will only make it worse!" or "Try utility NNNN instead.There are quite a few differences between the MS-DOS CHKDSK and ScanDisk, beyond the latter’s friendlier interface. HOWEVER, whenever I try to run it from my DOS boot disk it tells me I need windows. I know that the defrag.exe program supplied by Microsoft supports Fat-32. I have back-ups so this is a solution, BUT one that will take me a lot of time. ![]() Failing this I will get out "Spinrite" and try that (but that takes forever) and if that yields no results it is OS re-install time. HOPEFULLY moving explorer off any "failing" portion of my HD so I can at least boot up. What I am HOPING to be able to do is find a DOS-based Disk defragment utility that is Fat-32 compatable and defrag the drive. 2: There is a failing sector on my hard-drive that gives intermitent problems. 1: There is a file-system error NOTHING is picking up. I have also run scandisk (From a seperate boot-floopy) with surface scan and found nothing wrong. Since then I have used my bootable Norton Rescue Disks to run disk-doctor with a surface scan and there was NO problems. THEN, "explorer" dies and I am left with an unuseable computer. Windows will boot up through the windows 98 Splash-screen, display my desktop picture, and give the startup sound. ![]() Returning home that night, I foud a HOSED windows. But my time was up and I had to go to work. Likewise my computer ran fine in all other respects and shut down just fine. I immediately ran disk-doctor again, and everything was okay. Partway through the defragment it stopped with the error "unable to read cluster 1549657" and so I quit the program. Everything checked out A-okay so I procedded to Defragment it using Norton Speed-disk. Yesterday I ran Norton Disk Doctor to ensure that my Hard-drive was in good working order. My computer is running windows 98 and the Hard-drive in question is 6 Gigs. Hello, Recently I have had the unfortunate experience of having my PC become unbootable. ![]()
