Support for wiper.sh and hdparm --trim-sector-ranges-stdin is included in both openSUSE 11.2 and 11.3. Thomas Hertweck reported:

I have now installed openSUSE 11.3 on a OCZ Vertex 2E SSD. I used a standard ext4 filesystem, the mount options at the moment are "rw,noatime,acl,user_xattr". Unfortunately, wiper.sh doesn't work at all.

No joy, obviously.

I have asked Mark Lord (the hdparm maintainer) for feedback. He said the default max TRIM payload sent via hdparm has been lowered in the latest release of hdparm v2.30 and recommended we upgrade and see if it fixes the problem Reproducible: Always Steps to Reproduce: 1. Run wiper.sh against a Ext4 FS on a OCZ Vertex 2E SSD 2. 3. Actual Results:

$> wiper.sh --verbose --commit /dev/sdb1 wiper.sh: Linux SATA SSD TRIM utility, version 2.6, by Mark Lord. wiper.sh: This tool is DANGEROUS!

Expected Results: All EXT4 unallocated space on the SSD should be "trimmed" such that the SSD can erase the unallocated sectors in advance of their being used, thus improving performance of the SSD.
