Problem with Sanpoint and IDE access

Hi,

I am using Montavista 2.4.2_hhl20 with a Sanpoint (8240) board and I am trying to add a hard disk on the IDE interface. I can access the hard disk correctly. If the hard disk has previously been formated and partitionned on another Linux system I can mount all the existing partitions and access all the files on this hard disk. If I try to write on it the partition table is totally destroyed and I cannot acces anymore to the hard disk. It seems that read operations are correctly performed but not write operations.

In the same way if I try to add a new partition, when I save it the existing partion table is totally destroyed

Any idea ?

Thanks for your help

Claire
