Questions re. partitioning of CMI III MFX 2 with 11.39 and large SSD
2016-05-03 by dkevefnzs@yahoo.com
I've finally plugged an SCSI-IDE interface, an IDE-SATA converter and a 128 GB SATA SSD together and put the image of my original 2.2 GB Seagate SCSI disk onto the first portion of that drive.
I've successfully booted AND used the machine for a while.
Now I was wondering:
Could I bring an MFX partition (currently on an external HDU) onto that same SSD?
And, doing that - can I increase the size of the main CMI partition towards 4 GB, and then STILL place an MFX partition behind that (with 124 GB of course :-) )?
Or do I have to keep both the CMI and MFX partition within the first 4 GB of the drive?
Thanks a lot for any answer of yours.
I can also provide more details and any results if anybody is interested.
Kind regards, Joerg.
Some other remarks:
Over the years, I remember having read about disk size / or sector number limits in OS9 at 2 GB or 4 GB, and maybe about large disk support in MFX3 or later - but I don't know about the MFX portion in 11.39.
I'm sure going to review suitable postings on this list as well as other documentation. After all, Partition Magic or gparted will probably not support the CMI, or would they? :-)
I've been after replacing the internal HDU for years, tested multiple CF or SD cards on several adapters I had lying around. The system would boot but locked up after some work, and afterwards the image would not completely boot up again.
After I've seen the same with the SSD, I've enabled termination on that SCSI-IDE adapter - even though there are terminators on both ends of the existing SCSI chain - and thereafter it worked flawlessly. The adapter is Ultra-Wide, after all, so the normal terminators on the 8-Bit SCSI cable may have left some bits floating. Still may go back to test it with a 4 GB or 8 GB CF card as well.
But anyway, the SSD is definitely so fast it should never hinder the system in *any* way, and its excessive size should provide reserve sectors for wear leveling forever - so I might just stick with it.
I'm also unsure how to best transfer the content of a CMI partition when I would want to enlarge it. Apparently, the xbackup or xtotape tools in the system already can't handle the current 2 GB size or process a whole directory tree with all subdirectories - so I guess I'll need to have a source and a destination HD connected and copy the stuff over in the running system, which will take quite a while... or look into the direction of KMI9000. So, I'm going to read further, but would still appreciate any hints.
Thanks!
