And I also already knew how to get rid of that (delete the IDE controller from the device manager and reboot). And that issue was very obvious, because booting up alone would take four times the usual time. But in this case, windows detects the maximum speed when you install the SSD, so if it is UDMA5, you can suspect that this is the maximum. Nevertheless, I tried changing the registry according to the linked instructions, but the transfer mode remained UDMA5. Anyway, the difference between 70MB/s and 100MB/s should hardly be noticeable in everyday usage, because the main things responsible for a noticeable faster speed are average access time and IOPS (input and output operations per second), and these are a multiple times faster with an SSD compared to any hard disk, especially with these slow 1.8" 4200rpm hard disks.

Worth a go perhaps?

I was wondering if the issue would occur with Vista too. Well, I installed a fresh XP, I even customized it a bit using nlite. All I did was install the drivers from the HP homepage, but none of the HP tools provided there except HP Battery Check and Quick Launch Buttons. And HP Update. Also, I disabled the fingerprint reader in the BIOS, I don't use it anyway. First I thought that the problem might be caused by the missing HDD shock sensor driver, so I installed it, but - as expected - it only told me that the installed drive is not supported. And the problem remained. Ah, interesting. I was wondering if the issue would occur with Vista too.

I believe the problem might be related to part of the HP Protects tools. I removed various parts of HP Protect tools, the only thing left is the BIOS configuration aspect, and the problem seems to have gone away. This was a constant problem before removing most of Protect tools suite and now only pops up on rare occasions. I had a similar problem on the 2710p, Vista Business 64, and the Mtron 1.8.
