used for data destruction

edit

an organization i volunteer with[computer recycler] uses this program to erase donated hard disk drives and test the integrity at the same time. i believe they make four passes, and it works by writing to a sector, then reading back the sector and listening for change. any errors abouve a certain threshold are failed and torn apart for physical destruction...if any more expirenced editors care to add something about this procedure in 99bluefoxx (talk) 17:42, 14 June 2008 (UTC)Reply

disambiguation?

edit

shouldn't there be a disambiguation page mentiong that "badblocks" may also refer to the actual badblocks and not just some program used in a certain OS to deal with them? --TiagoTiago (talk) 12:31, 22 April 2009 (UTC)Reply

No, because the bad blocks to which you are referring are actually bad sectors. You could, however, link to that article if it isn't linked in this article already.--86.8.252.7 (talk) 23:53, 15 January 2010 (UTC)Reply

badblocks need to be updated

edit

1. The number of blocks tested at one time is very small (only 64K) If you increase this to a MB at a time with -c 1024, you can almost double the speed of the badblocks utility.

2. badblocks can't handle disks over 2TB in size.

Wikipedia should mention that.--71.194.190.179 (talk) 18:51, 30 July 2011 (UTC)Reply

The 2TB limit is simply the product of
  • 512-byte sectors
  • 32-bit block numbers
Both of these have been resolved in later versions of fsutils.

Isn't it a GNU utility?

edit

The lead says that it's a Linux utility. Isn't it actually a GNU utility? 83.104.249.240 (talk) 01:08, 29 March 2018 (UTC)Reply
