    If you try Knoppix you may want to use smartmontools and parted. Try them
    if you get a chance.

    Of course you are presuming MS-DOS; DR-DOS has had history without needing
    a driver or TSR from the beginning and IIRC, the 4DOS command interpreter
    did/does as well.

    I had a Maxtor 300 gig drive go toes up April 13 (yep, Friday). 260
    gig NTFS partition showed up as un-formatted, no partition info. My
    brother suggested "GetDataBack for NTFS". It took 6 hours to walk
    through the partiton and re-construct the directories so that they
    could be copied to a new drive. You can try this for free and then pay
    the registration to actually recover the data. Nearly everything was
    salvaged. The casualties were small (<50 Kb) word files but almost all
    the photos and .WAV files were fine. There is also a version for FAT
    for $10 less. It wasn't a fun week but it ended up better than I
    hoped.

    Thanks for that suggestion. I got the trial of the FAT version to see what it
    does.

    Do NOT use Spinrite.
     
  6. DRDOS was a DOS replacement OS. Yes, it had history function.

    4DOS' command processor was not called "command.com".

    What's your reason for saying that ? I'm not going to btw, but I'd like to know
    your reason.

    Depends on the data on it.

    I am considering getting SpinRite. If it is half as good as they say, it
    should be worth it!

    Yesterday, I revived one drive and recovered a lot of data using chkdsk/f,
    then chkdsk /r, then using r-studio to recover the data.

    I was working with two drives that kept freezing my test computer and even
    when mounted in an 'external usb' enclosure had problems.

    The second drive went down hard, rebooting the windows XP computer I was
    trying to access it from and then freezing the computer during boot. I had
    recovered some data before it died, but the owner is going to lose a lot.

    I tell my users about a guy I knew that had 9 years worth of research notes
    in his car (before computers were desktop size). The car caught fire and
    burned. No backups of the data. Never finished his research project. A few
    years later, he blew his brains out.

    Moral of the story: make backups, frequently AND store them in a different
    site than where you keep your computer!

    Experience. I can't count the times I've used it and been sorely
    disappointed with it's results. It also taxes an already failing drive
    sometimes to the point of complete failure. At one time long ago it worked
    slightly better with MFM and RLL drives to refresh the media but I can't
    remember a time when I've used it and when it was done, all was fine and
    dandy.

    Best to use Get Data Back for FAT and quickly recover the data that you
    can recover and be done with it. If you need a copy (for evaluation
    purposes only) I can get it to you. It's small enough to fit on a floppy
    IIRC.

    Nothing of any value I haven't already got a copy of.

    I'm interested in doing it for the challenge mainly.

    Try IBM's drive fitness test. It may be able to repair the drive.
    I've seen a lot of their drives suddenly develop lots of bad sectors.
    The drive fitness test was able to reallocate them without destroying
    the data on the drive. Run the extended test, then it will allow you
    to run "sector repair" when it finds the first bad sector. Most of
    the drives I've repaired with DFT worked fine for several years and
    are still working today (although I wouldn't trust them for anything
    important after that).

    If you just want to be able to copy the files off the drive without
    windows stopping you with a CRC error, try Western Digital's "Data
    Lifeguard". It's a windows program that's designed to copy files from
    your old drive to your new one and it works with non-WD drives. The
    nice thing about it is that it doesn't stop if there's an error. It's
    great for a drive that has a few bad files among thousands of good
    ones.

    I forgot to mention that IBM is now Hitachi Global Storage (hgst.com).

    They were alright for the most part, I had a few fail but most lasted pretty
    well and were quiet but slow.

    These days Seagate is the only consumer grade drive with a decent warranty
    so it's all I buy when possible. I've also had good luck with Western
    Digital though they put out a few turds several years ago.

    What was that 3 platter turd that caused them to give out replacements?
    Maybe it wasn't 3 platter but I think it was a 1.6 gig????

    The problem with that idea is that you can't get to that lower level any
    more. That door closed with the introduction of IDE / ATA drives many
    years ago.

    One more thing that they belatedly cloned from DRDos / NovellDOS.
     
  17. joseph2k

    joseph2k Guest

    Actually that was/is a DOS "TSR". A separate program provided by others.
     
  18. joseph2k

    joseph2k Guest

    Yes, it had better functionality and speed in a very similar memory and disk
    footprints.
     
  19. joseph2k

    joseph2k Guest

    You can get that. Do some re-search.

    DOSKEY was supplied by Microsoft.
