Hi,

Does anyone know of an (ideally) free disk erasing program I can run
from Windows XP?

I've used freeware KILLDISK on my smaller 60gig drives but they each
took over 3 hours. I was able to wait for them because I used an old
IDE computer.

I have two 120gig hard drives I need to erase before I can sell them.
And these new drives are SATA so I need to use my main computer. I
can't afford to wait 6+ hours for each drive to be cleaned.

Thanks!

Built into Windows' diskpart:

list disk
select disk #
clean all

Sorry.

Is that bad? On this disk,

Model Family: IBM Deskstar 40GV & 75GXP series
Device Model: IBM-DTLA-307030
User Capacity: 30,738,677,760 bytes
ATA Version is: 5

it took about 165 minutes to overwrite the disk, once, with pseudo-random
numbers. IIRC, it didn't take quite as long to write zeros.

Do you have some reason to expect that some other program will run in less
time while still overwriting the entire disk? Are you worried that someone
will use "forensic" tools to examine the free space on these disks?

Your BIOS uses PIO, not DMA, so it was limited to ~10MB/s.

Still too long if that is the two platter model.

The time to erase a platter at 7200rpm is under an hour.

That does not perform disk erasure required for security purposes.

Clueless Troll. Writing anything to a modern disk is not recoverable.

I wonder why you do not have 12 hours, but do have the time to
post here and wait for a reply? I think you have your perception
of reality screwed up.

Its going to take a while to do a security wipe on drives that size.

There's a list of other ones at the bottom of that web page.

interesting point but it usually doesn't take 12 hrs for a good reply on
this group

It *never* was. No disk was ever made to read the previous contents.

Try Eraser or zero fill utility of your hard drive manufacturer.

This is a link to research done by some computer scientists at Carnegie
Mellon that shows that the implementation of several commercial erasers
is flawed and data can be easily recovered.

I was really surprised to read that the implementation of the commercial
software products was this poor.

These arent doing what he wants to do tho, wipe the entire drive completely.
They're attempting a much more difficult task, wipe a drive thats still going
to be used with most of the files on the drive retained for use.

Hello, Ross,

I've recently downloaded Eraser, and it should do what you need. You can
wipe the entire disk, unused portions of it, or individual files. You can
select the type of security wipe you desire and specify the number of
passes. A one-pass wipe is reasonably fast. The documentation is superb. It
can be scheduled too. It's also free. I like it.
