Re : Root Disk Removal

[Vincent_5]

Hi,
Can anyone advice if there is any template that I can use to remove the os and data from a root disk. This is because of security reason as my company want to decommission a K-Class server and want to remove the data on the root disk with proper documentation and proof that the data and os on the root disk is already wipe out. Please help???

Regards
Vincent

Simple way would be to insert the drive in another system and newfs the drive. Then write some large files with 0's to fill the drive.
That would be a cheap way...
Here is a good thread to read up on:

You can write zero's directly to the disk also. Something like the following script should do it:

echo "0"| while true ; do
dd of=/dev/dsk/c0t1d0
done


Replace the device file name above with your device file and let run for 30 minutes or so.

Hi Vincent,

I guess your company can afford purchasing Ontrack DOS Eraser for $36 or so. This utility is known for meeting military security standards. It would erase all data, then create 7 overlays repeatedly on the HDD.

Cheaper (Freeware), "Sure Delete" would sweep the disk from existing data and any remains from older installations, then write randomly-generated data of its own over them.

Personnally, I use to get under a DOS session from a boot-diskette, then DELTREE all and any files put to the disk. At a second stage, I'd FDISK (taking on option 1) and format the HD in order to complete the process. However rekon it's not 100% secure.
