^^^ While I was doing housekeeping today I noticed that the first person to explicitly describe the process was mia. So hunt for his posts. There was a thread or two involving several people that finally got it all together. The firewire disk does work well when you get it going (with a couple of gotchas to be careful about.)

I bet you see the same when you connect this disk to a PC. Could it be you're hitting the 48bit limit of either your IDE disk or the 1394-ATA bridge in the enclosure?

I've had to flash the 1394 bridge in an el-cheapo (Conceptronics) enclosure once, and I know some ATA disks have a jumper to limit their capacity (and force compatibility with crap BIOSes)

At 137GB it's LBA28bit limit, not 48. LBA48 solved the 137GB barrier problem.

Windows XP can recognize and deal with a disk partitioned by Irix and formatted xfs ?
Any ideas as to how to get it properly work under IRIX?

What is your mount command ?

I'm surprised that Windows is even that capable :P

Simply via /etc/fstab, the following line:

Code: Select all

/dev/dsk/1394/10b92000b71b63/lun0s7/c3p0  /exstor  xfs  rw  0  0

I manually do something like this :

mount /dev/dsk/1394/d04b561107262b/lun0vol/c1p0 /usr/people/memyselfandi/firedisk

It also looks as if you may be mounting the wrong partition ? Sorry I can't double-check right now, am using the new sata disk and don't have the firewire connected at this time.

From memory, zafunk did the dirty work. Manually mounting a firewire disk worked best for him so I didn't bother to reinvent the wheel but you may have a better method ...

How much bandwidth loss to expect when replacing direct fw access with GigE NAS and small form-factor embedded PC with fw adapter :?:
For removable flash cards usage only, instead of a fw reader, has anyone tried a stack of adapters like SCA to 68-pin + Acard SCSI to IDE|SATA + IDE|SATA to CF (+ optional CF to SD/MS if media is other than CF) ? I hope this does not upset mediad. If this works, I would enjoy hacking a drive sled with those adapters and a sheet metal enclosure because a big fan could act as a shredder on a microSD card :twisted:
Back to topic, how much to pay for fw to/from sdi converter ? Then how to choose between ODV+MGRAS or DM2 ?

I know only the Miranda DV-Bridge+. New ~ $2K, second hand still a little pricey for my taste: http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 0333602781

You have a Tezro, just grab a cheap LSI SAS3442X-R ($45 BIN on eBay) and slap a drive on that instead. I have a 750GB SATA drive in mine - shoved it up above the DVD-ROM drive. Works great, no fuss, no muss.

Sure - he has three listed at that price:

If you need an internal SFF 8484 fanout cable, those are around $20 BIN on eBay.

I have a Adtron SDDS, which is a PCMCIA -> SCSI converter. A no name PCMCIA->CF converter got a 1GB CF onto my Octane. There is support in the desktop and mediad, as it will display a little pccard icon (akin to a CDROM or Tape.) Performance was very unexciting (reads about 500KB /sec,) but I don't know if it is the Adtron, the converter, or the CF card. I'll have to try a CF->SD converter.

Hmmm .. only problem is that is not an SAS3442X-R .. the "-R" is quite important, the none-R ones do not work .. I tried one :-(

I think the working part number is LSI100100 or something.
