[comp.sys.amiga] undelete

bilbo@pnet02.cts.com (Bill Daggett) (04/28/88)

Is there a new version of "Undelete" or a different "something" that will
locate and undelete files in a hard drive partition?

Do you know what happens if you open a drawer, select some icons with 
extended select, and choose discard from the menu???  It's sort of fun
watching your files disappear, until you see the window disappear and 
the drawer go away.  Oh Sh%t, the drawer icon was selected!!  Stupid Mistake.

No problem, right?  Well the only undelete programs I have are ancient
and only work with floppies.  I have SectoRama or something close to 
that, but will it work with FFS?

Does anyone have a simple undelete command that will work with a hard disk 
FFS partition?  Right now I have one partition of my harddrive that I am
afraid to use until I can get the files back.  (The name of the partition
is DATA:, which means I can not balance the old checkbook untill I resolve
this.)
Thanks in advance.

I use DiskSalv.

When you delete a file you didnt really mean to, you must remember
to not write to that device again. Run disk salv and it will
allow you to recover selected files (ie. only the one you
deleted).

Well, you could get a smaller drive.  Or start DiskSalv at the disk ROOT,
where you often find most files located.  But other than that, there's not
a heck of alot I can do to speed up the scanning phase (the last bit of
speedup I did involved the little "DiskSalv Scan" window that opens up
during a scan; writing directly to the window, rather than to a console,
made scanning over twice as fast.  If you want it any faster, use the 
QUICK option.

While it's by no means a perfect solution to your problem, a new version
of DiskSalv is nearly complete that makes this kind of thing less painful
if not perfect.  The new version supports a new option that will let you
scan and match a given file name regular expression.  Thus, 

	DiskSalv DF0: DRF: FILE #?.c

Would scan for only files that match the #?.c pattern, in any directory,
on the input disk.  

A true undelete program, aside from possessing the ability to relink a file 
rather than just recover it as DiskSalv does, would do well to get real
smart about the directory scanning phase of the operation.  There's really
nothing you can do, in worst case, to avoid scanning over most of the 
disk, but you can make some intelligent guesses about where a child file
might be if you know where its parent is.  I have been thinking on the
subject, but unfortunately haven't had any time to go beyond the thought
stage on this one.

With apologies to Chris Elliot:

	Dave, Dave, Dave---I wasn't knocking the program that has saved so many
so much grief and lost data, not to mention me from having to send back my
ARexx distribution disk.  I was just (too subtly, I guess) pointing out that
using DiskSalv to undelete is like swatting flies with the Oxford English
Dictionary.

Talk about your ultimate bummers...

I use my Amiga for writing scripts, primarily. I like Word Perfect more than
MS Word on either the M*c or I*M. And, for the most part, it handles script
formats very well. (why my agent uses an Atari ST I'll never know...)

Buuuuuut, one day I went to call up my movie, all 128 pages (132K), and guess
what? No file.

Somehow it got killed, and I have nothing to undelete it. Where, WHERE, can I
get something to undelete lost files?

BTW, the same disk went bad, and half of my scripts were toast. I suspected a
virus, but it made itself known. Viruses usually let you know they're around.
Nothing. And Virus Checker didn't find squat. Eventually DiskSalvage recovered
a few scripts, including a new Star Trek, but for the most part, a lot was lost
when my data disk seemed to just fall apart.

I use FixDisk for undeleting lost files, as well as for repairing bad
disks.  FixDisk version 1.2 is on the (recently released) Fish disk
number 403:

    FixDisk	    A program to recover as much as possible from a defective
		    disk.  It can sometimes recover damaged (unreadable)
		    tracks, check file integrity, check the directory
		    structure, undelete files, copy or show files, fix
		    corrupted directory pointers, etc.  Full intuition
		    interface.  This is version 1.2, an update to version
		    1.0 on disk 223.  Binary only.

Can this utility restore deleted files on a harddrive?  If not is there a prg t
hat can?

If it's not intuitively obvious, DiskSalv can be used to restore a
deleted file so long as said file's blocks haven't been overwritten.
There might be more you have to worry about but the BEST this is just
plain "DON'T WRITE TO THE !#@$%&* DISK" at all.  I recovered a file this
way just last night.

I think the best program for undeleting is FixDisk.  It will undelete files
from a hard drive if the partition is not huge.  Make sure you use the newest
version, because the older ones had problems.  I believe the newest version
is on NASA, but if you can't find it, I would be more than happy to send it
to you.
