Too bad the pc Unixes don't have a format command like Sun has had for Solaris/SunOS....tells the hard drive to 'format' and then tests with a number of test patterns.

Been wondering why no one mentioned mke2fs
From the mke2fs man page
-c Check the device for bad blocks before creating the file system.
If this option is specified twice, then a slower, destructive,
read-write test is used instead of a fast read-only test.
From the badblocks man page
-w Use write-mode test. With this option, badblocks scans for bad
blocks by writing some patterns (0xaa, 0x55, 0xff, 0x00) on
every block of the device, reading every block and comparing the
contents. This option may not be combined with the -n option,
as they are mutually exclusive.
Isn't writing 10101010 then 01010101 then 11111111 finall 00000000 enough
I guess you would do (assuming a single partition on an ide drive) mke2fs -c -c /dev/hda1
then
dd if=/dev/zero of=/dev/hda
just to clean out the parition info.
