RD1000 DMA and Eject Issues

Hello all,
 
I'm having some struggles with an RD1000 implementation I'm doing.  I'm an IT tech managing about 25 client networks, mostly running PowerEdge 1800's (some 1900's and 2900s as well).  I've installed the Internal RD1000 SATA into a PE1800 at one of my client sites, and we're having several difficulties.  I'm hoping there may be some Dell tech that reads this and can shed some light.

 

Yes, I've installed, removed and reinstalled the RD1000 software CD like 3 times now, which has not provided even the slightest change in symptoms described below, so I don't believe it's likely a "reinstall the software" issue...
 
Problem #1: Lack of DMA.  I'm unable to get the DMA enabled on the device.  The controller (Computer Hardware..Device Manager..IDE ATA/ATAPI Controllers, the "second" Primary IDE Channel (which is really the SATA channel) Properties..Advanced Settings Tab, Transfer Mode is set to "DMA if available" but current transfer mode is always "Not Applicable".  As a result, any accesses are INCREDIBLY slow (about 2 to 3 Mbytes/sec) at best.  This makes server backups about the same speed as DAT72.   

Problem #2: Lack of ability to Eject.  Stick the cartridge in, you're NEVER getting it out unless you:
   1) Log in to the server console.
   2) Open up My Computer
   3) Right-click on the RD1000 drive and select "Eject".
 
This is clearly a problem when the person responsible for changing the daily cartridges is a "non-admin" type user who just knows enough to "put the little black cartridge into the cartridge-shaped hole" and now must be given at least enough access to the server to log in and run the steps above.  The eject button doesn't work.
 
So, anyone have any assistance?  Can we get a firmware update (either to the PE1800/SATA controller or to the RD1000 chassis) that resolves these issues?  I'm sitting on my hands and trying to hold off clients from buying these drives until we can get them working better in these PE1800's.  It also would be helpful if Dell were to produce a small .EXE program like RD1000Eject.EXE (just offering a name...) that would just eject the cartridge.  At least this way, I could add the command to the end of the backup script so it automatically ejects when completed.

 

Disclaimer: Yes, I'm PERFECTLY AWARE that Dell hasn't "certified" the SATA RD1000 in a PE1800.  That said, I'm supporting about 20 of these servers and my clients are virtually clawing at me to get these RD1000's to replace their relatively antiquated and klunky DAT72s.  So my opinion is that I think Dell should "fix it" if there's a problem on these 6-month to 24-month old servers. But I digress...
