They're still around ?

I have used Ontrack tools in the past but I imagined they'd gone the way
of all things.



Yes. If only a modern OS would let you do that !

I well recall a specific instance where I'd goofed slightly due to poor
documentation (jumper settings in the early days of IDE master/slave
drives) and thankfully didn't panic and **** up. Norton sorted it. But
then again, Norton wasn't Symantec back in those days.

Don't you love it when Norton says 'this drive has a damaged partition
table. Would you like to recover it ?'

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

Command.com is NOT "stripped". It has never had a history function
without running a TSR to manage it. That would have been (not anymore)
DOSKey.

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.

Thanks for that advice.


Is there a trial version ? It's $89 to buy.

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.

DRDOS was a DOS replacement OS. Yes, it had history function.

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

Do NOT use Spinrite.

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

It's hardly worth $89 to resuscitate an old 20GB drive.

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.

Never seen this before.

A HDD of mine (IBM Deskstar 20GB IC35L020AVER07-0) 'died' when I restarted
Windows (XP btw FWIW). Windows shut down OK seemingly but wouldn't restart.

It totally 'locked up' the PC with no error message. Never seen anything quite
like that before so it took me a little while to pinpoint it. The BIOS found the
drive OK btw.

Anyway, I got things sorted and then re-attached it as a secondary drive.

Trying to look at it, Windows Explorer 'froze' for a bit but it did load a drive
icon eventually. However Windows Explorer was of no further help.

I then used XP's command.com and got the cryptic message 'cyclic redundancy
error'.

Any ideas what's up ? Is the drive destined for silicon hell or is it
recoverable ? I'm wondering if the system area's data's been trashed for
example.

Graham

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.

Never tried one after their eighties problems with severe sticktion.
Loved their fix, too; make the motors pull harder to break the heads
loose.

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????

Get a copy of Spinrite. It works for errors like the one you have. There
are other tools which are for filesystem corruption and lost
files/partitions but it sounds like you have something a little 'lower
level' than that.

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.

There's a commands.exe (in c:\HP\BIN) on this Vista <spit> machine
that seems to be similar similar (if not identical) to cmd.exe.

Note that cmd.exe (and my commands.exe) allow you to use the up-arrow
key (or F3) to copy the previous command (as well as other things) so
it's a lot more pleasant to use than the stripped command.com.

Best regards,

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

In Win9x you can enable command line history by typing "doskey".

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

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

What's this then ?

Type of file: MS-DOS Application
Description: command
Location: C:\WINDOWS\system32
Size: 49.4 KB (50,620 bytes)


Graham

As I said, I'm basically ignorant of XP, and what little I know about
it I learnt from watching alt.msdos.batch, and by working
[reluctantly] on friends' machines.

In any case other XP users have suggested that you would be better off
using cmd.exe. In fact, if I were to include just one feature of XP in
Win98SE, it would be XP's extensions to batch language.

- Franc Zabkar
You can get that. Do some re-search.
