Release Notes: The "-I" argument now reports the maximum number of 512-byte blocks of range-data per DSM/Trim command. Consequently, hdparm and wiper.sh now use only as many LBA ranges per TRIM command as the drive can handle. The man page and the help text were cleaned up.
Release Notes: The order of flag execution was rearranged so that the idle/standby/sleep "now" flags are executed last.
Release Notes: Use of HDIO_GETGEO_BIG is now avoided, as it is deprecated in newer kernels. Secure erase timeouts now have bigger padding. SCT identify information has been improved. The ordering of the "-S" and "-y" flags has been fixed. The block-count of security commands sent via SAT (sgio) is now set to 1. FIGETBSZ is now used to determine the filesystem block size for fibmap. Sector dumps are now forced to the le16 output format. Many other minor improvements, bugfixes, and documentation improvements have been made.
Release Notes: A new "-R" option has been added to control the Read-Write-Verify feature.
Release Notes: The wiping script wiper.sh was updated to allow all SCSI_DISK major numbers. The handing of very long SECURITY-ERASE times was updated. The "-J" flag was added for wdidle3 set/get.
Release Notes: RAID 1 start_lba values are now handled. The "--fibmap" command is now terminated when start_lba is indeterminate. wiper.sh was modified for an issue with HFS+ file systems and to avoid using an obsolete command.
