hardware compression for VXA-2 tape drive

on a Windows XP Pro PC with the Veritas Backup Exec
software (version 4.5).

Has anyone managed to disable the hardware compression

You can with vxaTool, available from www.exabyte.com. You do need to execute
it each time the machine starts up as the drive defaults to compression

I did try that. Apparently it either does not work or Backup Exec
does not respect it. It would be nice if it was a permanent change
to the tape drive.

...Sony SDX-500 AIT tape drive problems
Throwing this out there to see whether anyone else has had the same
problem and can offer suggestions before I go to site to look at it.
We have a Sony SDX-500 AIT tape drive connected via an Advansys PCI
controller to a Compaq rack-mount server running Linux. The drive is
used on a weekly basis to backup an important filesystem using the dump
The drive, having worked in the past, has started exhibiting the
following behaviour (reported by users on site, so subject to their
having passed the correct info on to me): on placing a tape in the

I am about to buy a Sony AIT1 AITi90/S (a.k.a SDX-400C) tape drive
and I'm trying to work out whether it will work with an ageing Adaptec
2940UW card that I have had for years.
The Sony specs say "Ultra Wide SCSI Single-ended / Low Voltage Differential
68 pin connector". The Adaptec card has two 68 pin connectors (1 external,
1 internal) and a 50 pin internal connector thrown in for good measure.
Judging by the name, it's certainly Ultra Wide SCSI, but how do I tell if it
supports LVD? (Do I need LVD?)

I suspect that this old HP35480 tape drive is not backing up to
capacity. Possibly becuase hardware compression is turned on, and the
backup software i am using uses software compression (AMANDA)
I have looked over the mt(1) man page and tried the compression
commands which exited silently and nothing in the logs suggested that
compression has changed.
I have just found this excellent posting circa '94 which seems to
explain why the mt commands don't appear to work...
So my question is "How do i send a mode select command under linux?"
I realise that i could set/check the switches on the device, however,
i'd much rather be able to do this remotely and without interrupting
Thanks in advance,

If this is your suspicion (sp?) (which is a sensible one, because
software and hardware compression often/nearly_always conflict) then why
don't you disbale the hardware compression on the drive itself? AFAIK,
on all DDS drives, especially the old ones, you can (enable/)disable
hardware compression by setting a switch (or jumper) on the...Sony Tape Drive Compression
This group appears more suited to this question than comp.compression...
I have a Sony AIT-2 SCSI tape drive using 50/120 GB tapes and Retrospect
Backup 6.0. Sony's compression ratio is advertised as 2.6. The maximum I've
ever gotten on a tape using hardware compression is around 57 GB.
I realize compression is dependent on file type, and I am backup up a mix of
non-compressed and compressed files. But, out of curiosity, what have others
seen using this drive? Using a backup of an operating system drive (w/ no
user data) as a reference may make comparison easier.
Tha...DLL errors: The hardware, the hardware, it's ALWAYS the hardware...
As John stated in the DLL Hell thread:
"Really? How many of those links are cases of "DLL Hell'? Thats where
a program replaces an existing Windows DLL with its version. All these
are a bunch of links where a DLL is missing or corrupted. Its a pretty
safe bet that 10.3 also will suffer from missing or corrupted files due
to disk problems. As evidenced by the frequent need to trash certain
programs preference files."
This is the age-old "cheap unreliable hardware" argument that John
always runs back to when cornered about Windows' shortcomings.
Isn't it interesting that whenever Mac advocates bring up Apple's
unique ability to integrate high-quality hardware and software, the
Winidiots always blast Apple for not selling cheap commodity hardware?
Yet whenever Windows has a problem, the Winidiots always seem to blame
it on "cheap hardware." Some Winidiot always loudly trumpets the fact
that "you can get PC system X down at Fry's for $499," but whenever
Windows fucks up, the excuse is "well, what do you expect from a bargain
You can't have it both ways, kids. Either cheap hardware is a
benefit, or it's a curse. It's been proven that Apple's high end
machines (Dual G5s) have a significant price/performance advantage over
dual Xeon systems, yet Wintel lovers like to whine about how expensive
Macs are. If you combine this with the fact that...Sony AIT-3 tape drive

I have a VAX 4100 to which is connected a disk tower (SCSI) from the port on
the back of the VAX.
I think I can connect a tape drive to the inside of the disk tower, as I see
another port in there. But I don't have a cable that fits.
On the other hand, I do have a SCSI cable that can connect to the tape drive
directly from the VAX. As the tape drive has another connector, I figured I
could then go from there to the disk tower.
I tried, and at the >>> prompt a SHOW DEVICE now shows several MKA devices

I'm using Sony's S AIT-1 internal drive for backup purposes in a Win

compression when performing backup, although it's enabled through the

Device manager, i see the "Compression Enabled" parameter set to
FALSE. (although the the drive is Compression enabled..).
Does anyone have an idea how to set this to TRUE, that is to Enable

When I was trying to back up my SyQuest EZ135 SCSI hard drive on a PC,
I ran in to an interesting problem. I had the PC (parallel) version of
the EZ135, and a SCSI version (hooked to my OS-9 machine). When I
inserted a non-DOS formatted platter, the PC would not recognize it.
The BIOS (or something) wanted the first sector to be PC-ish. So, my
solution was to write a quick program in C to back up the first 512
bytes (sector) of the OS-9 disk, and copy the 512-byte sector from a PC
disk to the OS-9 disk. This created an OS-9 disk (unusuable) that
would be recognized by the PC. From...Two drives: OS on Drive 1, Progs on Drive 2, My Docs on which?
I'm considering my partition options to give the best performance.
I already have a single Western Digital Raptor WD1500 ADFD.
I have my OS (XP Pro), applications and documents in separate partitions so
the drive head is having to spend a lot of time moving between them.
I wondered what improvement might be gained if I bought a second WD1500 and
changed where I store things.
So would it be better to have the OS and apps in separate partitions on
Drive 1 and My Docs on Drive 2? Or OS on 1, apps on 2, My Docs on which?

hi all. We're planning to migrate several linux servers, with applications
installed (like oracle, etc.) , onto another newer hardware, which I am to
install linux (preferably an updated distro version) as well.
I'm a bit of newbie, but what I imagine is that instead of installing on the
new machines from scratch -- OS plus apps plus accompanying data -- which
would take too much time, can I install an updated version of linux distro
first, and then after that, just copy all the directories in the original
box that are not dependent on the OS (such as /var, /home, /etc, /usr, ...)?

I have been having some issues running backup on my Linux file server
the past few weeks. The server setup is as follows:
OS: Red Hat Enterprise Linux ES release 4 (Nahant)
SCSI Card: Adaptec 2940
Tape Drive: Sony SDX-500V (Internal AIT-2)
Backup Software: Bru (version 16.0)
The tape drive is the only SCSI device in the server
What happens is, it backs up perfectly fine for a while, backup,
verify, and restoring from tape works beautifly! Then all of a sudden
it starts giving an error, it still backs up, just the backup never
seems to finish completely:

If this is not the correct I apologize up front.
Our company is doing a Hardware/OS Upgrade on our AS400 this weekend
and I wanted to get a feel on the approach that is being taken.
We are planning on going from an 810 with v5r2 on it to a 550 with
v5r4, we are moving existing cards in the 810 to the 550 as well as
the 5074 Tower and then restoring from a SAVE21 on the 810 to teh 550.
Is this feasible or would there be a better approach. We are unable to
upgrade the exisintg 810 to v5r4 first due to the disk configuration
of the system which is not supported by v5r4 for the load source. So
we are moving hardware from teh 810 to the 550 installing v5r4 base os
and then running a restore from a SAVE21 of the 810.
Any feed back would be greatly appreciated.

I really liked Hardwar and would be willing to play a persistant online
server. My only real complaint about the game was the dynamics (or flight
model) or the ships is too simplistic. However the rest of the game
somewhat makes up for that.
Also Hardwar has the best soundtrack of any game I've played. I ripped it
to MP3 and play it with the rest of my music all the time.
