Data Security

I am selling a couple of Win 98 machines to an outside agency. They both have contained documents and Databases that would have contained sensitive information.

My question is how can we insure that this data is very hard to retrieve once it leaves our control?? I have formatted the drives and reinstalled the original recovery disks, containing the original OS and Software. Is this enough??

In a word, NO!

There are a couple of ways to make it very hard to recover any data from the drives.

The first is to use a DOD certified drive cleaner utility. These write a sequence of 1's and 0's to the drive anywhere from 3 to 7 times.
Then, when you format the drive and restore the original OS, it is very difficult to recover any data.

The second, is to remove ALL partitions from the drive. (Boot from a W98 startup disk and run fdisk.)
Then, set up new partitions of different sizes than the original partitions.
Format the new partitions, and if desired, change the partition size again.

The more that you do, the harder it is to recover data from the drives.

If the data is worth someone spending thousands of dollars to recover, I recommend destroying the drives and installing different drives into the systems.

On a side issue, if these systems came with OEM versions of Windows, read the end user license agreement closely. It may be a violation of the EULA to sell these systems with the OEM software.
