The system hang up
wait a sec...you cannot delete the partition...why not?
what error message?
Could be. But in the mean time I destroyed my data. :-) I tried deleting the disk array and recreating it. Now it is empty. :-)
That sounds slightly different--perhaps faulty raid controller.
If that is the case, a similar motherboard/raid controller may be able to retrieve the the data.
I decided to quit using the raid system. I pulled the connector out of the array controller en plugged it in the ide controller on the mainbord. I formatted a part of the first disk and now reinstalling Windows on it. No problems with that so the first disk seems to be ok. The second disk is recognised by the system and a small partition is formatted too. So I guess both disks are fysically ok.
That means the raid controller is the problem or it was just very bad luck as I turned the power off. I guess the latest. But as I decided not to use my raid system again and lost my data anyway, it doesn't make any difference.
Sad but I have to live with it.
Thanks for your support.
