worked with 2.6.1, 2.6.5 also.

Older kernels do not work well with this device. The device has several flaws. Device is also "blacklisted"
DMA not supported on several controllers.
Do your research before you buy a Seagate.

I have one.

Nice except for the bug...

To clarify the above post, with a Sil controller there is a bug ( mod15write bug) that means for system stability it needs to be limited to writes of 8K sectors.

I had the harddrive lock up whilst writing video from firewire. This was stopped by adding this device to the 'blacklist' in the kernel source. The side effect is hdparm -t results dropped from ~53Mb/s to 13Mb/s. :(

But at least it doesn't freeze my system anymore.

Detected from install from Mandrake 10.0 onwards. Works great with Via controller (south bridge).

I have never experienced any of the bugs mentioned by above posters. However, I bought the drive in July, and it failed about 2 weeks ago (hardware failure). I am now waiting on my RMA shipment of a new drive. hdparm -tT results were very disappointing for the speed of SATA. My 80GB ATA/100 hard drive received nearly identical ratings (less than 2% difference). I cannot, however, be certain if this is a chipset or hard drive issue. For reference, my other drive-related hardware is as follows:
Motherboard: Asus P4C800-E Deluxe (ICH5 Chipset)
CPU: Pentium 4 2.8 GHz Hyperthreading (Northwood)
RAM: 1 GB (2x512 MB) Corsair Dual Channel PC3200 DDR

Accordingly, I feel the only bottleneck is likely to be the SATA drive itself. While it is very compatible, as far as I have seen, I would strongly urge AGAINST buying one.
