blocking factor for qic wide?

blocking factor for qic wide?

Post by VAll » Tue, 05 Mar 1996 04:00:00



I have a connor 420 tape drive which works well except I can't seem
to store more than 171 meg on a tape which is susposed to hold
200meg native & 410 compressed.  kernel 1.2.8

tar -b58 -czf /dev/ftape /v1

I suspect that the blocking factor (58) from the howto for qic-80
may be wrong for qic-wide.  Does anyone know the correct value
or what else I may be doing wrong?

Thanks in advance

1. SCO tar error on block size (not block factor)

Someone recommended:
tar cvfb - ./config 32768 | compress | dd of=/dev/rmt/0m bs=32k  
tar: invalid blocksize. (Max 20)
0+1 records in
0+1 records out

Seeing his/her error i supposed that what they meant was the actual
block
size in bytes to match the 'dd' record size.  But
tar cvfB -  ./config 32768  | compress | dd of=/dev/rmt/0m bs=32k
tar: B: unknown option
Usage: tar -{txruc}[0-9vfbkelmnopwAFLTP] [tapefile] [blocksize]

        9       /dev/rctmini      20      0          Yes    
        10      /dev/rdsk/fp03d   18      720        No    
        11      /dev/rdsk/fp03h   18      1440       No    
        12      /dev/rdsk/fp03v21 10      20330      No  

Is there a way to get tar to match the 'dd' record size please?
