Solution:

Customer that has used PCA-6157L with Seagate discs in the past and has been advised of an incompatability with 4 models of Seagate IDE disc. They are today using another PCA-6159 with a Fujitsu 1.7GB disc and are having problems installing the QNX operating system (It reports "Unable to write to disc"). The card has recognise the Heads/Cyls/Sectors of the Fujitsu disc correctly. (It may be a QNX problem) (1) Can you pls confirm that as far as you are aware there is no incompatability with discs other than the Seagate units (2) Can you maybe advise what the Seagate incomptability means (ie: it total lack of communications, intermmittent errors or what?)

Seagate admite this problem and they will change the controller on new version. So far, there is no way to improve the compatibility between Seagate HDD and TX chipset. Please change your hard drive with others to solve this problem.
