What is the command to test a disk integrity

[Grayh]

#dd if=/dev/rdsk/cXtXdX of=/dev/null bs=64k count=1000

Hi:

# dd if=/dev/rdsk/cXtYdZ of=/dev/null bs=1024k count=100

...drop the count option for an exhaustive (!) read of the entire disk.

Note the use of the raw device file to eliminate use of the buffer cache.

If the number of recoreds and equals the number out, you can perform I/O without error.
