[ILUG] blocksize for a DLT drive?

[Leccardi, Diego]

Hi Ronan,
my suggestion is to set the bock size of the DLT to 1024 using the command:

mt -t /dev/st0 setblk 1024 <= it should improve the performance a lot

With the dd command you can use the option "bs=1024k".

Why you don't try Storix? http://www.storix.com/
It's free for personal use and it will create a bootable cd in order to boot the box and restore the system.

Hi Folks,

I have a machine here that I want to preserve the last-known-good
state of in a fashion that Linux can read. As such, I'd planned on 

dd if=/dev/[disk] of=/dev/st0

where st0 is a DLT8000 drive. Thing is, it's been doing that all night
and still is showing no signs of being finished - it's a 35GB
partition and I assume it's moving one 512-byte block at a time. So my
question is, what's a good blocksize for the DLT drive? The drive
itself doesn't report a preferred size, in fact it says "block size:
0" when I ask it.

Cheers,
Waider.
