The disk is 1048778 blocks. I created a 512M image and copied it bit-for-bit to the disk. I think i'll just go SYSGEN 4.8 and wait for my cleaning tapes to get RSTS/E working.
How about copying the image back off, to see if the disk controller mangled it?
I'll do that once RSX is up so I don't have to dismantle the system again. ;)
The message you quoted says that the content of block 1 is invalid (the pack label). Judging by the code, what it found is 0143161 rather than a valid PCS.
Interesting. I wonder how its getting mangled. The disk size IS changing between copy and creation, though. (Because both are different...apparently unavoidable due to 1000 versus 1024k.)
I wonder if your partitioning disk controller is misbehaving.
Possible...but RT-11 and RSX-11 are fine with it. They're a bit less picky though. VMS didn't seem too picky, either.
BTW, sufficiently recent versions of RSTS (including the one you have, given that message) should handle a 2 GB disk directly (at DCS=64). That way you don t need to mess with partitions.
I didn't have a tape drive at the time...so I would've needed to copy a 2G image at 10Mbit to a disk that wouldn't show up as 2G. (That drive then failed)
I'll just wait for the cleaning tape.
