HP OpenVMS Systemsask the wizard |

The Question is: I have been trying to install a SONY-F561 MO drive onto an ALPHA ES40 server using KOMNETWORKS third party software. However, I am intrigued to find that I can load up the drive using standard vms procedures and be able to initialise/mount/copy the disks without any problems. However I can only do this if I use a rewriteable disk that has 512 bps only. What I would like to know is, why can I only use 512 and not 1024/4096 bps? Regards Andy Wright The Answer is : By BPS, the OpenVMS Wizard will assume the reference is Bytes Per Sector. (And not Bits Per Second, another commonly-used abbreviation.) OpenVMS VAX, OpenVMS Alpha, and OpenVMS I64 all use and all assume a 512 byte block for disk storage, and contains support for reading and writing devices that provide this block size. (OpenVMS typically uses the terms disk block and disk cluster for the addressable and allocatable units of disk storage, respectively.) OpenVMS has no particular support for this device and this device may or may not function (reliably or otherwise) at any particular setting, and you will want to contact the device vendor for assistance. For general third-party device integration and related information, please see the OpenVMS Frequently Asked Questions. Specifically also see the section on OpenVMS and CD block-size support, as that discussion is very likely related here.
