I am running opensuse 10.3 on an HP Pavilion which had an SATA drive preinstalled, and I have added a second drive from my old machine which is standard EIDE. When I did the installation of suse, and since, the OS does not see the second drive at all. It does not appear in the partitioner, Konqueror, system information, or anywhere. This is a known good drive, and there have been no hardware changes since I had it running under Vista. It is listed in the BIOS, and Vista was able to access it (when Vista would actually run ). I have another machine of a similar configuration (sata + ide) and the installer didn't see the IDE drive there either.

Since I have removed Vista from this machine, I now have no way to access the data on that drive. Note that this drive has never been visible to suse from the time I first put in the installation dvd.

Any ideas?

That's definitely not the behavior I would expect from OpenSUSE.

Post the output of 'fdisk -l' please.

fdisk? There is no fdisk. This is not a dual boot system with XP.

Oops. I had tried fdisk -l before I made the previous post, and nothing happened. I didn't know that it was available only to root.
Anyway, this is it:

Partition table entries are not in disk order

Here's something interesting. When I booted the system from Pendrive Linux, both hard drives were visible in the file manager. So, apparently, this is a problem specific to Suse.

Check in YaST and make sure ntfs-3g is installed. (I think that is what it is called) If your second hd is ntfs file system you will need this to read it. Apparently it does not come default on some distros
