used for data destruction

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?

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

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?

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]
