Released disk-filltest 0.7 - Simple Tool to Detect Bad Disks by Filling with Random Data

Posted on 2013-03-27 21:32 by Timo Bingmann at Permlink with 0 Comments. Tags: #c++ #utilities

This post announces the first version of disk-filltest, a very simple tool to test for bad blocks on a disk by filling it with random data. The function of disk-filltest is simple:

  • Write files random-######## to the current directory until the disk is full.
  • Read the files again and verify the pseudo-random sequence written.
  • Any write or read error will be reported, either by the operating system or by checking the pseudo-random sequence.
  • Optionally, delete the random files after a successful run.

See the disk-filltest project page for more information about version 0.7.
