MHDD doesn't support AHCI.

March 2nd, 2009, 7:10

Therefore, it is necessary to set it in ATA interchangeable mode with BIOS. This is too inconvenient to inspect hundreds of PC.
Because MHDD is a very excellent tool, the thing that AHCI is not supported is sad. :cry:

I want to support AHCI with MHDD by all means.

Give to Master Dmitry a valid reason to do it... :)

Recent PC is connected with AHCI with the factory shipped.
It is ATA-compatible-mode, and functions such as NCQ and HotPlug cannot be used.

I want to use MHDD with an excellent tool in the future.
However, it is troublesome work that changes the BIOS setting whenever MHDD is used. :cry:

When MHDD supports AHCI, a lot of people can become happy. :)

SATA hotplugging will work with MHDD in IDE mode because it doesn't rely on the BIOS to detect or configure the device. You can actually hotplug IDE devices with it too, not that I would recommend you get into the habit of doing it frequently. I use a hot-swap bay (connects/disconnects all pins at the same time) with it all the time and it works fine, even though most parallel ATA devices and controllers really don't support that use.

NCQ is totally irrelevant to anything relating to testing or data recovery, as you typically end up wanting to slow things down if anything, rather than speeding things up. You want a drive to work on one thing at a time, not to queue up tasks and do them all as quickly as possible.

AHCI might be needless to MHDD.
However, AHCI is necessary for Windows.

The example is given.
1)Windows is started like BIOS-ATA-Compatible-mode carelessly.
2)Windows will build in another driver for the ATA device besides the AHCI driver.
3)The thing being built in for an extra driver is very unpleasant.

This event is human-error.
However, this error doesn't occur if MHDD does AHCI-support.



I want to explain an incidentally personal circumstances.

I should execute the inspection of HDD to hundreds of PC.
The BIOS setting is changed one.
And, MHDD is made to run. This is easy.
The act of returning it based on the BIOS settings of many hundreds of afterwards is only a nightmare.

Get another tool. What do you want from a FREEWARE?

HDAT2 has been used for another.
This is more excellent than MHDD in the SMART function, and supports AHCI.

However, the function to examine how many slow sectors there are is not provided in HDAT2.

If Windows is installed configured for AHCI, you can switch back and forth and it will work fine.

Bottom line is, if you want to use it on your AHCI configured machine, take the 20 seconds it takes to change from AHCI to ATA mode, and then the 20 seconds it takes to change back.

Let's resurrect this topic. AHCI support is useful, when there is no option to set IDE mode in BIOS. For example, Sony Vaio SE laptop supports AHCI only (and MHDD does not detect any disks).

Is that reason serious enough? :)

MHDD source code now belongs to Seagate, therefore I guess you would have to ask Seagate about it. I have no right to publish source code or continue development, unfortunately...

Pzar....take a look at the dos version of Victoria. Current version is maybe 3.33.
I think you will find it to be a more than viable alternative.

Can also just get an old or refurbished cheap tower to dedicate only to MHDD testing. Ensure you have a good power supply unit.

If you only have one monitor, get a basic kvm switch.
