Hello,
What controller do you mean? The eSATA or ... ?
There's nothing on HP Driver Portal for my Laptop

The external drive is the i've already searched for drivers on Targa website, but without any results. I've found a manual and read that this drive is HotSwap compatible.
What is your BIOS SATA Mode setting? AHCI or RAID?
Now that is a good question. I tried to find any Info about this in BIOS but i didn't. I've already flashed my BIOS version, but no changes...
So. If I start up Win 7 and my Ext. HDD is already on, I get a PopUp in Win7, that the ...driver for SAMSUNG HD753LJ Device was successfully installed
...ready for work
Also I find out how to "recognize" my ext. HDD if Win7 is already started. I just go to device manager and let it "re-scan" for changed hardware..and then i can see my drive.
And there's another thing. If my ext. hdd is on and was recognized I can plug or UNplug the eSATA cable in my Laptopn - hotswap (hotplug) works, but if I turn my drive off and then turn it on again - hotswaping doesn't work till I recognized it with device manager
"What controller do you mean? The eSATA or ... ?"
Your "IDE ATA/ATAPI-Controller" listed under that is "Intel ICH9M/M-E Family 4 Port SATA AHCI Controller - 2929" right click this and click properties, check the driver version. Check HP for the latest driver-chipset version and driver-storage version, if you already have the latest 'driver-chipset' then go to the Intel website and find the latest version from them, check the 'Release notes' for fixes that might pertain to your issues. Updated or driver from Intel might help, I had 'issues' with the OEM driver and am using the one from Intel.
""AHCI or RAID?" Now that is a good question..."
Your "Intel ICH9M/M-E Family 4 Port SATA AHCI Controller - 2929" is telling you it's a SATA driver. If it said 'SATA RAID' then it's a RAID driver. I'm not familiar with HP BIOS but maybe someone in the forum might be able to give you an answer. Mine is in 'Advanced tab, listed as 'SATA Mode' choices are IDE or RAID.
The last part of the above post tends to make me think your BIOS is in 'IDE' mode, or the external HD would be recognized when turned off then back on, going to Device manager to 're-scan' is an IDE trait. I can plug and un-plug the eSATA external HD and it is recognized each time without scanning for new hardware, I use 'HotSwap' program to "safely remove hardware".
I would contact HP or their user forum and find out how to find the SATA mode setting in BIOS.
1st thing u need to check is the RAID mode settings (sata config) in the BIOS of your computer
Is it set to: IDE, AHCI, or RAID
SATA Modes (AHCI; Hot Swap)
The SATA controller has three modes of operation:
* IDE mode - no AHCI, no RAID
* SATA mode (sometimes called AHCI mode) - AHCI enabled, no RAID
* RAID mode - AHCI enabled, RAID enabled
AHCI mode also allows for Hot Swapping drives.

Great post, Bugzz this is good info.......
I choose this method because I didnt have AHCI enabled when I installed W7 - if you have AHCI enabled prior to installing W7 the driver will be loaded automatically.
.......
You simply change a registry entry so the MSAHCI driver will install. Reboot, go into bios -.........
Haven't tried this way (but will if needed again), but sounds pretty much like what I did.
Downloaded Matrix Storage Manager and driver from Intel, went to my storage controller driver in Device manager, in the drivers tab click 'update driver' choose 'Browse my computer for driver software' find the driver files, install, when it asks to re-boot, then re-boot and go to BIOS and change from IDE (or ?) to AHCI or RAID. The AHCI driver must be loaded to switch to AHCI and the RAID driver must be loaded to switch to RAID. Continue the booting process, should be in AHCI or RAID. Then I loaded the Matrix Storage Manager (if your switching to RAID). I switched mine from IDE to RAID.
When I did this it worked, no blue screen. If you get a blue screen just re-boot and switch SATA mode back to what it was initially, and it should start up fine.
Hello.
I've already tried to change MSAHCI value on win 7 registry...everything i get was an BSOD (thankfully I've made a restore point)
The other problem is that I AM NOT able to change controller mode in BIOS. The reason is - there's no switcher or button or something else to do that. There’s no any information about controller mode in BIOS. I've already flashed my BIOD to 'newest' version, but no changes.
Actually I have two suggestions:
1 - I think I have RAID enabled, because i have in my Laptop. HD Tune Pro info - ... Furthermore, I had a label on my laptop...something with RAID, but unfortunately, I've removed them.....so I think, i have RAID enabled. :sarc:
2 - If i hadn't ACHI/RAID enabled, my laptop couldn't be able to hotswap my ext. drive in Win Vista
So... everything I need is a tool which helps me to find out, what mode is enabled...AHCI or RAID
Any ideas?
The hot swap may be a function of your MOBO and controller.
I would try to find the information on how to find the 'SATA mode' in your BIOS. Maybe HP has it set one way and it can't be changed.
If you load the AHCI or RAID drivers and re-boot while SATA mode is set to IDE you will get a blue screen.

EDIT:
If you removed "something with RAID" you have likely disabled RAID. Just re-read that, you said you removed a label.

From what you have mentioned previously, your SATA mode is not working correctly, Try re-loading the drivers, it will help narrow down the problem.
They should be available on the HP Drivers site.
Let us know how it's going,
