[mod.computers.vax] RP07 from VMS to TOPS and back.

CY13@TE.CC.CMU.EDU.UUCP (02/24/87)

Currently we have some RP07's formatted for VMS and several formatted for
Tops.  We would like to be able to interchange these from time to time as
hardware konks out.  I am aware that each system needs to see its own formatting
(36 bit vs 32 bit).  We are aware of how to format each type.  However we have
heard a rumor that it is not possible to take a Tops-20 formatted RP07 and
reformat it for use on a Vax.  Can anybody confirm or deny this?

Please let me know and I will digest the answers back to info-vax and tops-20.

Thank you all for your time and consideration,

Curt:
This is not a direct answer to your question of can you reformat an
RP07.  
However, we were faced with getting data from a DEC10 RP06 disk to a VAX
and solved it by using a dual-access RP06 disk drive and developing code
to run under TOPS10 to access the RP06 in the VAX' Files-11 format.  We
were thus able to format the disk from the VAX, then dismount it from
the VAX, mount it from the DEC10, write DEC10 files to it, dismount from
DEC10, mount from VAX and read the data.  If you'd like further details
let me know.
