hdparm
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".

Recent releases
- 17 Apr 2009 14:38
Changes: LBA48 bugs on big-endian machines were fixed. The "-m" option was fixed to work with libata.
- 09 Apr 2009 00:24
Changes: All accesses are now O_RDONLY again, to keep Debian/udevd happy. The DSM determinate/indeterminate TRIM support is now displayed in -I output. The output of CFA features from -I was tidied.
- 22 Mar 2009 12:16
Changes: A problem with O_DIRECT ("--direct") for architectures other than x86 was fixed. Some whitespace was stripped from output.
- 28 Feb 2009 23:17
Changes: The output of "-I" was updated with SATA-2.6 additions, and "form factor" and "rotation" displays were added to it. APM level retrieval is now supported with the "-B" flag. The "-C" output was updated to match ATA8. Logical/physical sector size reporting was added.
- 15 Feb 2009 20:48
Changes: ATA_16 is now the default again, as this is required by libata for ATAPI devices. The "--prefer-ata12" argument was added to allow forcing the use of ATA_12 when needed (e.g. some USB enclosures).

Compiled from v9.15 sources, hdparm crashes at hdparm.c, line 1826, when get_identify_data() returns NULL. Checking that id!=NULL is needed.

libata does not have a way to control DMA or 32bit PIO settings. So the command will fail. Normal. Ignore it.
Libata will always use DMA if possible, so no need for either setting.

Inappropriate ioctl for device
Hi all,
I get the above error.
This is on ubuntu 8.10 2.6.27-9-generic
$ uname -a
Linux shirish-desktop 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 GNU/Linux
$ sudo /sbin/hdparm -c1 -d1 /dev/sda
/dev/sda:
setting 32-bit IO_support flag to 1

HDIO_SET_DMA failed: Inappropriate ioctl for device
IO_support = 0 (default)
HDIO_GET_DMA failed: Inappropriate ioctl for device
The disk in question is an IDE drive in emulated SCSI mode due to ubuntu moving to the new 'libata' library.

Re: How to erase the whole disk ?
I believe you are doing the right sequence of steps, so the problem is likely a broken kernel call in the old IDE drivers.
I do know that there are bugs in the kernel ioctls() HDIO_DRIVE_TASK and HDIO_DRIVE_TASKFILE have bugs in some scenarios, with the old IDE drivers. So that is what is probably causing it not to work for you.
If you need this kind of functionality, your best bet is to switch over to the modern libata kernel drivers, which are replacing the old IDE ones. The libata kernel drivers fully support hdparm and the SECURITY_ERASE functionality.

How to erase the whole disk ?
Hi all,
Since quite a while I want to erase my harddisk on the secure erase method. hdparm supports
this, but I always get the same error 5.
I use version 6.9
root@Knoppix:/media/hda1# hdparm -V
hdparm v6.9
The first thing I do is ask some info about the disk:
root@Knoppix:/media/hda1# hdparm -I /dev/hda

It looks that my disk supports enhanced security erase. Now I set the password, but
this already fail:
root@Knoppix:/media/hda1# hdparm --security-set-pass test /dev/hda
/dev/hda:
Issuing SECURITY_SET_PASS command, password="test", user=master, mode=high
Problem issuing security command: Input/output error
Error: 5
Then I tried to unlock, but because the password setting failed, this doesn't work either.
root@Knoppix:/media/hda1# hdparm --security-unlock test /dev/hda
/dev/hda:
Issuing SECURITY_UNLOCK command, password="test", user=master
Problem issuing security command: Input/output error
Error: 5
And the erase also give an error:
root@Knoppix:/media/hda1# hdparm --security-erase test /dev/hda
/dev/hda:
Issuing SECURITY_ERASE command, password="test", user=master
HDIO_DRIVE_CMD(erase prepare) failed: Input/output error
Can somebody help me to work this out ?
Thanks a lot,
Lotje
