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".

The wiper.sh script was enhanced to enable unattended operation, to handle SIGPIPE, and to support hfsplus and NTFS file systems. The man page was updated.
AHCI issues in sg16, caused by asking for sense_data on DATA-xfer commands, were fixed. Compilation on old systems lacking __be16 was fixed, along with occurring compiler warnings.
The SET_FEATURES commands are functional again. "--user-master" now defaults to "user" instead of "master", for better drive compatibility. The drive-supplied timeout is now used for security-erase commands. The default general timeout was raised from 5 to 15 seconds. Other minor modifications were made.
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.
