Check and see what version of the ROM you have installed in the Supra controller card in the 500XP. You have to look for a sticker on the ROM chip which will say AMAB#. The old versions of the ROM have problems with other hard-drives and newer versions of Workbench. You need the latest version (there was someone on Ebay selling the latest ROMs for $15US about 6 months ago, I bought mine then and am now running WB2.1 no problem). I think the drive installed is a 105MB Quantum. Before the new ROM was installed, it would not recognise all the partitions, now it does. With the AMAB6 ROM chip installed, I can use the HDtools included in Workbench 2.1 without problems.
The chip is IC9 located
under the internal hard drive.
The new ROM also helps with using multiple SCSI devices, CD-ROMs and processor cards. I wouldn't be surprised if you have version AMAB4, which could possibly also give trouble with later versions of Workbench (beyond 1.3).
http://amiga.resource.cx/exp/supra500xpFrom and old message on Usenet:
"If the rom is labeled AmaB6 the supra controller will support large hard drives and Cd-Rom drives. If it is labeled AmaB5 there is no Cd-Rom drive support and if it is labeled AmaB4 or earlier there is no large hard drive support.and from another:
"According to the Supra Faxback Document 1501 dated 4/24/96, the current version of the autoboot ROM is "AMAB6". The document also says that the "AMAB6" ROM is required for use with Workbench 2.0x and above."Let us know which version you have.
