Arch Linux

http://forums.fedoraforum.org/showpost.php?p=1383963 take a look at a quick fix there

Not working any longer, since "rdev" is missing.

rdev is no longer part of util-linux-ng.
The rdev man page itself describes it as an "ancient hack" and says using it is "strongly discouraged".

2.8 is released, together with hdparm 9.30 (9.29 is in testing atm).

Wiper is a fallback if you use old kernels (graysky's correct) or if your SSD firmware doesn't support auto-trim. Orphaning package since this isn't a common case.

Just so I'm clear... is this software needed when using a TRIM enabled SSD and kernel >=2.6.33? My understanding is that if one uses the 'discard' mount flag and the modern kernel-26 package, TRIM support is handled by the kernel itself with no need for wiper.

# SSD
/dev/sdb1 / ext4 defaults,noatime,discard 0 1
/dev/sdb2 /home ext4 defaults,noatime,discard 0 2

2.7 @ http://sourceforge.net/projects/hdparm/

Okay, It seems to be working fine now. Thanks for your hard work. It sure is nice to have this utility managed in the repo.

Indeed wasn't committing the trims. Fixed in rel 3 (for OCZ drives too) with updated patch from SF's issue tracker page.

Hum, "is" this patch working with the new wiper? When I ran it it shows no error but it ends super fast and shows nothing under the "Trim ranges: "
(I have Intel G2)

The Intel G2 patch has been applied from echoblack. Works on my Intel X25-M 160G with ext4.

Cool, ya I'd like to have this patched for the Intel G2's if it is needed. Thanks for considering the G2's, and supporting this package.

Adopted and updated to wiper-2.6. Will test with Intel G2 range bug and include the Intel patch in release 2 if needed.

Shouldn't this be a part of the hdparm package?

I have uploaded the patched version of wiper.sh for Intel G2 SSD's

Disowning because of lack of time! Feel free to adopt and update.
