When I bought my HP PC Windows XP was running on the SATA disk. I added a IDE disk for data backup and the system ran perfectly for 3 months with both disks. Suddently the IDE disk and the DVD-drive were no longer visible in Windows.
The motherboard is equiped with 4 SATA ports and one IDE port for two devices. IDE disk and DVD-drive is attached to the IDE.
In BIOS setup both disks are recognized as well as the DVD-drive on the IDE.
I have tested the disk drives with PC Doctor from DOS, and they were both reported without errors.
In Registry HKEY_LOCAL_MASHINE/HARDWARE/DEVICEMAP/SCSI both disk drives and the DVD-drive are visible including the type number. However in the device manager neither the IDE disk nor the DVD-drive is present.
When the IDE drive is disconnected the DVD-drive becomes visible.
I tested without the DVD-drive: IDE disk and DVD-drive are not detected.
I tested with another similar disk: IDE disk and DVD-drive are not detected.
I tested with another cable: IDE disk and DVD-drive are not detected.
I tested with cabel select and with disk as master and disk as slave: IDE disk and DVD-drive are not detected.
I tested the IDE disk in another PC running Windows XP on IDE disk and the disk in question is working fine.
Hope you can help on this.
