I'm having problems with my LTO-4 tape library (it's an Overland NEO 
4042). Drives will just sort of stop working (as in: reading a tape label 
will just never finish. If I unload the tape, and try a different drive, 
it will read fine). Overland Tech Support says that the version of HP's 
LTO-4 tape driver I have on my Windows 2003 NW server (1.0.6.3) is known 
to cause problems, and they suggest downgrading to 1.0.6.1. Problem is, I 
can uninstall 1.0.6.3, but I can not install 1.0.6.1 - the installer 
errors out. I can't install from GUI, from command line, extracting out 
individual INF files and installing that way, etc. Nothing I do will 
install 1.0.6.1. I can re-install 1.0.6.3 just fine .. but that leads me 
back to problems.

So: anyone else having problems with this version of the drivers? This is 
on Win2003 SP2 (32bit, in my case). NW 7.6.2. Tape library is fiber 
connected.

Or does anyone have a hint on how to downgrade properly - perhaps some 
driver cleanup tool is needed to completely wipe things clean before 
downgrading? I haven't found anything, or even hints to it, but I did have 
to use a cleanup tool years ago for some Symantec software, so it's not an 
unknown phenominom on Windows ...

(and why Overland doesn't have it;'s own drivers, for drives in it's own 
library, I don't know. But they sent me to HP for drivers, so the actual 
drives are HP, apparently. Or use the HP drivers, anyway)
