thank you for your reply. On IDE0 and IDE1, I have now 80 ribbon cables.
I don't think it is the gap because previously I had Maxtor on hda, Wd on hdb and the CD on hdc and I had the problem too with this configuration.
I think we can exclude the IDE0 connector too because windows makes no problem of it.
But the situation has improved
, since I have changed the hardware configuration, I haven't had the problem with knoppix HD installed (I'm touching wood now). Before I had it with the HD-installed knoppix too and I noted that linux doesn't react well on a reset; last time I had to reinstall linux.
Today unfortunately, I have seen the problem again but this was with the live version of knoppix. Most of the time, the problem happens when I'm accessing my Maxtor Hd. When I'm doing e.g. a format, a find file, copying data, ... Today, I had it when I was HD-installing knoppix and when the installer was copying data. So maybe it is the power supply which is ... 350W. When I'm referring to my previous hardware configuration, the swap partition was on the other drive what asks I'm afraid more power...
How can I calculate the required power?
If this is the problem, then remains the question: "Why is winXP not suffering from this problem?"
