You mean like "format"? Try typing it into the command prompt along with the letter of the drive to format.
actually its not a windows drive :D
i tried this application
Dariks Boot and Nuke
and from the sounds of the online reviews it used to be great, but I think it may be a virus now... even the "quickformat" function takes 90 hours +, starts off quick and then slows down after about 10 minutes. I fear my disk has really been nuked now :eek:
the ideal solution would be a secure disk format util that can format entire harddisks and maybe even ovewrite the disk with secure patterns, i thought it would be easy to find, but i've searched for hours
killdisk also has a bad rep from other people's reviews: http://www.killdisk.com/
it probably does exactly that, kills the disk rather than formats it.
I used XP Disk Cleaner, because I'm a XP user. You can find about it more from XP Tools Software. Actually it is work from Windows 95 to vista.
Dariks Boot and Nuke
trying the beta and seems to be a lot faster ;)
Most of them are like that.:pQuote:

trying another format now, but it looks like trouble...
do i have to rewrite every software myself :cry:
Yes you have, unless formating the system drive.
mbr + disk access, then write over every bit... should be so easy... :D then the os should format it for its use.
Correct, but normally I used full/quick partition. Otherwise it can be caused lots of problems later.

but there must be other non ms products that can securely delete harddrives ... even ms doesn't do the secure patterns...and it doesn't seem like a task worth paying 50USD for does it? and many people who have paid for such utilities have often been ripped off from online reviews.
Go to the HD manufacturers site and see if they offer a download of any utilities for low level formatting of the hd. That places the HD in the all zeros state like when it was first manufacturered.
ok thanks will try those suggestions
here's an example of how much rubbish software is available for securely deleting harddisks: review of Active@ Kill Disk - Hard Drive Eraser from cnet.com: (http://www.download.com/3000-2092_4-....html?tag=dl.1)
Cons: Don't pay for the full version, I did but I never received anything. They said they never received my payment, so I sent them a copy of my bank statement plus several emails complaining and they just totally ignored me. So my advice is to AVOID THESE PEOPLE LIKE THE PLAGUE. One finale note, the free version is rubbish.
I downloaded it... seems to be a windows application...does it format an entire disk or just files from within windows?Quote:

What is different is this application allows to securely erase things on the hard drive because if you erase something on the HD it not really erased. the DoD approved method to erase something from an HDD it to erase it 7-8 times. I don't remember the standard but things like boot and eraser allow you do this.
that's DBAN again arrggghhh....Quote:

most modern ide drives you cannot low level format.Quote:

you can just boot up with windows install cd and delete your parition then create it and a regular format instead of a quick and that will zero all your sectors on you hdd. the deleting and recreating of the parition will erase and clear your master boot record as well as your boot sector.
i tried DBAN 3 times... but unstable and erratic results immediately after diskwipe and loading os, when was stable before DBAN....
did you ever consider the stability is not from DBAN? All it did was erase the sectors on your hard drive multiple times. It is possible that it corrupt your filesystem table, but more than likely you wouldn't be able to install of that was the case.
did you reformat you hard drive before installing windows, or did you install on the existing parition? If you did't you need to delete your parition, recreate your c: drive then format it use the regular or long method not quick.
that will prove if it was dban. If you did all that, and it is still unstable you will have to look for other sources, or swap out a hard drive.
loaded a nix os... the nix os was fine before dban ... it has never had windows...
i may have to pay for a utility :rolleyes:
Learning_C, Based on my experience and your symptoms, i can tell you exactly what your problem is.
Your hard drive has bad sectors on it. This is perfectly normal, but it you do an unconditional format, the computer will try to format them again, and this can make a format that should have taken 20 minutes take 12 hours, because it will try every sector in the cluster one at a time even though one sector is enough to kill the entire cluster. You need to do a scandisk on your hard drive and have it mark bad sectors. Evidently a couple of the sectors that were bad or weak were missed in the format and now have operating system data in them.
And Finally, Never, Ever, EVER do a low-level format on a hard drive. It can ruin the drive, because it is possible to erase the sector markers. This is one of the reasons you can't do a low-level format on most modern hard drives. the other is the limitation of a hard drive controller in track and sector searching. Modern hard drives don't have the same number of sectors in each track, but tell the OS they do, for backward compatibility, and there is no way to read or write the information except on certain models where the manufacturer has released a specific program for a specific hard drive. A low-level format by the wrong program will screw the sectors up beyond repair and the damage can not be undone.
its a new disk, shouldn't have bad sectors... also I have written apps and included sdelete to do low level file deletes and never had a problem, the only difference is this time i want to wipe the entire harddisk, in theory should be a walk in the park especially with a live cd that can load an os for the programmer.Quote:

However, just the fact it is still working at all means you didn't mess up the sectors. Some hard-drives will prevent you from "low-level" formatting even if you think you did.
do fsck and find out.Quote:

This took me 8 hours with an 80-gig drive. Good luck.
LOL! :eek2:Quote:

Can you boot to knoppix, mount the drive and run fsck? That will tell if it is the file system is bad.
What kind of hard drive do you have? You can download dos based applications that will run diags on your hdd and determine if they are bad. You get them from the vendor site. Remember this diags are for physical layer. above is the software layer.
Yes. As stated before, wiping can delete the records of bad sectors, which got you into this mess in the first place. In the future, perform a quick-format. It preserves bad-sector markings.
Note that scan disk in windows has to be told to perform a surface scan, because they take so long.
i just tried the gparted live cd http://gparted.sourceforge.net/livecd.phpQuote:

now run the surface scan program he told you about. I haven't used that particular boot, But my Redhat let me choose full or quick format. Evidently yours didn't.
well before dban all i needed was to wipe and start over... now well i have no idea anymore... who would have thought it would be so hard to wipe a disk :rolleyes:Quote:

i refuse to give in to a windows format just yet although the cd has been in the drive twice :D
from memory the knoppix live cd is 600MB so i'd have to wait overnight (free downloads during nightime)
tried from the terminal nothing happenedQuote:

ok, get that out of your head, you don't need a utility to wipe your hard drive. a wipe utility is not to erase your file sectors. it going to what is in the sectors.
the fact fsck came up good, I really doubt it is the hard drive, unless it physically damaged, but I really doubt if fsck came up clean.
Your best option is get you linux install disk delete your parition, recreate them and install the os. I have repeated this a few times.
If you REALLY think your hard disk is bad, get a new one. This idea of having something wipe your hard drive is going to magically fix your problem is false. fsck passed. no file system corruption.
hey thx for the advice from everyone... the dban did strange things to my harddisk, although i think you are correct there is no physical damage to it, it just needs to be cleaned properly...Quote:

but i can't wait for days... so i gave in and booted into recovery console in windows to use the format command (shame i know)... then i'll try to reinstall my nix distro and go from there... its dissapointing that the nix distro that i have doesn't include a format function although i did notice a newfs command being executed when it loads its files, but it still loaded on unstably afterwards and it doesn't format the entire disk as it loads in 5 minutes flat ;)
it sounds like Lord Orwell has a linux distro (red hat) that includes a format util, its a shame there isn't a more secure stand alone utility for nix given that dban didn't work for me at all.
if i format and then delete the mbr dban should be removed shouldn't it?
what's the safe way to delete the mbr? Fixmbr? told me it could be bad news!
Also i could be wrong but it seems like it is almost impossible to get a proper disk wipe util, its almost like you can't even pay and get proper solid
disk wipe
proxy server
or encryption
;)
even though they are easy to code compared to most software
another alternative is that the distro that i have could be the cause of the instability not dban :D
downloading another distro now :blush:
i had to use fixmbr. Once linux gets into the mbr that is the only way to get rid of it again, and it is possible that for some reason it has screwed the partition table up, which the first 4 partitions are stored in the MBR.
by the way, if you have an older version of windows, the command isn't fixmbr.
it is fdisk /mbr.
