Yes and yes. :^)
Since July 2002, I've owned a Maxtor (Model FWRA080QVQ001) 80 GB external
FireWire (-1394a, i.e. 400 Mbit/sec) hard disk drive (HDD), bought expressly
for use under Linux (Slackware 8.0, back then, Slackware 9.1 today), although
I've tested it under W98se and it works fine there too, of course. At the
time, I also bought a Maxtor IEEE-1394 PCI card (which has no apparent model
number).
Although it doesn't see daily use, this HDD has always worked flawlessly. The
PCI controller card has worked perfectly under Linux as well, which was no
surprise since I checked the Linux IEEE-1394 website (mentioned in your post
above) first to find that the PCI card uses the known-compatible Lucent (now
'Agere') FW323-04 chipset.
The only thing I noted back then was the inability to 'spin down' the HDD,
since it's essentially seen as a SCSI device, so 'hdparm -y /dev/xxx' won't
work. Maybe there's some equivalent spin-down technique for SCSI HDDs that I
haven't yet heard of.... Anyone???
This Maxtor -1394 HDD also works fine on my Shuttle SN41G2 SFF (Small Form
Factor) PC with built-in IEEE-1394a ports (nForce2 chipset, using Realtek
8801 FireWire chip).
Aside: Although this SN41G2 IEEE-1394 setup has worked perfectly with the
Maxtor HDD, there was one oddity that I've not tried very hard to solve. My
Sony DCR-TRV38 camcorder would _send_ video just fine to the SN41G2 using the
built-in -1394, but when trying to send video _from_ the SN41G2 back _to_ the
camcorder (e.g. using the popular 'Kino' video editor app), it never worked
right. I wound up sticking that aforementioned Maxtor IEEE-1394 PCI card into
the single PCI slot of the SN41G2 PC and everything worked fine since then. I
have not tried any recent Linux kernels (or any other drivers or updated
-1394 libraries) to see if this has improved any with the SN41G2's native
IEEE-1394. I rarely export video from PC --> camcorder, so it's not a big
issue and the Maxtor PCI card works flawlessly.
----------------------------------------
Summary: The IEEE-1394 controller (on-mobo, plug-in card, whatever) is
important. Check compatibility first!
Bottom Line: Although I don't use it on a daily basis, I'm very pleased with
(400 Mbit/sec) IEEE-1394a hard disk drive use under Linux. I have no
experience yet with IEEE-1394b (800 Mbit/sec), though. Furthermore, IMHO,
short of having no free PCI slots, I cannot understand why anyone would use
USB (even USB2.x) for an external HDD when IEEE-1394 is so nice (easy, fast,
well-supported, problem-free, etc).
HTH....
