Re: sun blade 100 hard disk
It's a 40GB drive.
Take your model number, and do a google search.
WD400BB-23DEA0 plus, WDC has a habbit of putting the actually drive size
in the model number.

It concerns IDE devices. My Debian is installed now but when copy large

I am about to think that it is a DMA problem. But my knowledge
hardware is a bit limited.
- Is it an hardware problem ?
- may be a problem of connections between the disk and the IDE bus on

I don't know. I never noticed any problems with my 20 GB and 120 GB

(using ufs in Solaris and ext3 in Linux). I never did any tricks with
set the DMA level or something.
Things that come to mind:
- do you use a proper cable? I'm not sure if it's an ATA66 or ATA100
in the blade 100, so I use an ATA100 cable to connect the 120 GB
drive (20 GB
still uses the default cable that came with the box). I'm not sure if
and ATA100 cables differ, but for at least ATA100 it is required that
signal wire has it's own ground wire iirc (thus, a 40 pin cable has
- what filesystem do you use? I've read somewhere that there could be
with Reiserfs on sparc, though I don't know any details.
There is also a strange thing. In my dmesg, as in hdparm, my hard disk
is seen as a 40GB. But I am nearly sure that it is a 20GB (as detected
in fdisk) and as it is written on the internet.
I attach the output of my hdparm -I.
