[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



hdparm v9.2 is now available from sourceforge.

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

New since v8.9 are:

1. Support for Device Configuration Overlay (DCO),
  with the --dco-identify, --dco-freeze, and --dco-restore flags.
  DCO is a feature set that enables vendors/OEMs to disable/hide
  certain drive features (eg. NCQ, LBA48, ..) for whatever reason
  (eg. compatibility with a specific b0rked BIOS).
  This release of hdparm can display/reset DCO, but not selectively
  disable features yet.

2. Support for firmware download (upgrade) using the
  standard ATA DOWNLOAD_MICROCODE protocols 7 (preferred) and 3.
  This is initiated via the new --fwdownload flag,
  or the --fwdownload80 flag for a non-standard final packet
  (needed by some vendors).

3. Fixed WorldWideName display, and added cache-size display in -I output.

4. Detect/warn of kernel driver bugs in -N output.
  Eg. sata_sil24 misbehaves here in 2.6.25, but is fine in 2.6.27.

5. General fixes and tidiness in the sg16 routines.

Enjoy.
