Packet Request Type Unknown!!

[StevenJGore]

it seems that your CD-filesystem "cd.device" doesn't support every command ("packet") required by AmigaOS 3.9.

The CD32's filesystem can cope with OS3.9 and the installation CD perfectly.

You should try to use the CacheCDFS CD-Rom filesytem instead.

No you shouldn't! Support for the CD32's CD drive (including cd.device) is in the CD32's 3.1 ROM. There is no need to install anything extra like CacheCDFS, which will be ignored anyway. This applies to OS3.1, OS3.5, and OS3.9, but don't install the ROM update from Boing Bag 2 for OS3.9 because it breaks CD drive support.

'Packet Request Type Unknown' suggests (to me) that the CD32 has a faulty CD drive, more specifically, the lens could be faulty or damaged. Either that or the CD is damaged.

I doesn't own a CD32, maybe the CD Rom handler is so bad programmed, that it returns the wrong errorcodes and doesn't follows the standard (wouldn't be astonished, have a look at the Amiga's Ram-handler, that is so bad programmed (full of bugs) that it is a wonder that the system is stable

Using OS 3.9 with 3.1 Kickstart ROM I think, and CD filesystem in 3.1 is very outdated.

But it works perfectly for me! :-?  :-)

My CD32 with SX32 Pro and OS3.9 BB2 (but without the optional ROM update) ran for years using the CD support built into the 3.1 ROM without ever encountering an error with the CD drive reading CD's, even with the OS3.9 CD.

Since only one version of the 3.1 ROM was used in all CD32's (40.60 IIRC, and was unique to the CD32, being different to the 3.1 ROM's in A1200's because of Akiko support etc.) I can't think of an explanation for the inconsistency, other than a damaged CD or lens mechanism.

-EDIT- If the CD lens had become mis-aligned in this particular CD32, would that produce the 'Packet Request Type Unknown' error?
