Cannot format SCSI disk

[leofoe]

I bought an A2000HD today. It has an A2091 SCSI controller with a Quantum 40MB HD and an A2052 RAM-card. It booted OK a few times but now I get checksum-errors. Tried to format the disk. All seems to go well, but after rebooting nothing has changed. I cannot write to disk, nor format it. Can read only.
Is this disk dead?

OK, the A2000 (OS2.04) had 2 disks so I removed the faulty one (Wow, faaast are these SCSI's!).
But now I have a weird problem: If I run any program and want to open a file, the A2000 guru's.
If I try to use CrossDOS on DF0: the machine crashes on inserting any disk in PC0:

Checked the battery for leaking? Yes OK.
Reinstalled the drive? Yes, OK.
Pushed on all socketed IC's including the RAM on the RAM board(s)? I will do that.

I installed Workbench 2.1 on this sytem. When I install the libs of Workbench 2.05 I can open files from programs (different ASL.library?).

The CrossDOS-problem is solved by installing CrossDOS-Plus.

Now trying to get my bridgeboard going...

Thanks for all your information.
The A2091 had the Quantum on the card itself. I replaced it by the second harddrive: a Digital RZ23L of 120MB. It was mounted under the diskdrives with brackets. I did lowlevel format this drive. Shouldn't I have done that?
Anyway, it works OK now.
Because I didn't have the complete 2.05 install disks, I only replaced the libraries. The rest remains 2.1. That worked for the 'Open file' problem. ROM is 37.175.

The battery is not leaking. Even the time is retained.

BTW: Nice site you've got! And fast! Running on an Amiga 060?

2.05 requires the ROM upgrade you can`t use this with the 2.04 ROM.

Sure you can ...
You can run any OS ver 2.xx on the 2.04 rom.
I have run 2.04, 2.05 and now 2.1 OS on my A2k
with the 2.04 rom

If I use 2.1 completely, I get the Open file-problems described in my third mail. Probably it's the ASL.library that is giving problems.

As to low level formatting.... interesting. I am holding in my hand a 4.3 Seagate SCSI drive that I use as a paper weight cus it is of no use to man nor beast cus of the dreaded Low Level Format. Whilst I agree that LLF can work on older drives, and loads of new drives simply ignore LLF you give the false impression that there are no risks to LLF. I suggest those reading this go on a search for detail on the web and see what others say. Newer drives are factory formatted and this data can be destroyed by LLF.

I understand, but why do the manuals and the help functions nevertheless advise LLF?

In this instance the gentleman concerned has his drive on the machine and I assume he has an icon there. So why not simply format the drive with the software rather than risk anything. At least with my solution he wasn`t gonna destroy the disk. Sounds like that may have just happened. What do you think ... ?

I did the LLF after it was faulty, not before.

a: Check the ROM to see which version. Thats easy. Disable the hard drive and see what comes on the screen when you start up. Or check from the pull down menu if the hard drive boots into the OS for the version.

It's 37.175. That's 2.04, right?

d: If the 2.04 worked fine then consider updating to the 2.1.

I did that in the first place, but it is faulty (with the other (Digital) drive) in some respects (opening files).

One other thing we failed to mention is that the A2090 or A2094 came with Hard Disk Software. And I guess this guy hasn`t got that. Fortunately I do so I may be able to help.

What does this software do?

I do believe that they made a 2.05 ROM for the A2000. Managed to track an advert down on the web. Not sure they are still about. Dunno.

I don't know either.

Anyway, all comments appreciated. I do apologise again to the guy with the problem for my inaccuracies. And trust me I`m not being sarcastic... I`m just new to this Amiga Forum.

No problem.

I would advise to read posts well before reacting.
I am in Amiga's for 20 years. But SCSI, that's new to me.
