Re: [Networker] Problems changing blocksize on Win2003 - Resolved
2009-12-10 10:29:29
I fixed it the easy way ... I used an Adaptec 39320 SCSI controller
instead. :-) It supports a min blocksize of 64K, but a max blocksize of
256K (by default), so NW has no problems resetting the blocksize to read
my 128K blocksize tapes.
Thanks
