hdparm is a Linux shell utility for viewing and manipulating various IDE drive and driver parameters. Most drives can benefit from improved performance using a command similar to "hdparm -qm8 -qu1 -qc1 -qd1 /dev/hda".
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.
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.
