Hi

These Quantums are very old and given that its a 40mb makes it probably the original, so failure is likely given the masses of use of a very small drive. One word of warning and that relates to formatting. I trust you didn`t low level format the drive from the toolbox.

You simply right click on the icon and format. You will need your install disks. Also the 2000 was the most widely modified and upgraded of the Commodore range so check the ROM, cus they started on the older 1.3 version Workbench.
2.05 requires the ROM upgrade you can`t use this with the 2.04 ROM. Version 2.05 was released for the A600 and 2.04 was supplied with the A500+ and A3000. You will appreciate that the later Workbench's needed the hardware fix.

The hard disk isn`t mounted on the card with this version so just check the seating. I`m guessing there is some battery leakage, which may not be first evident. There are plenty of examples of such things on my website, including battery probs with the A2000.

If the machine was playing up like this when you got it then it will be difficult to track down the specific probs. Best bet is to fire up on the floppy disks and see if she runs properly and detects the hard drives. The PC0 isn`t that relevant at this time. Could be an incorrectly set up DOS driver Tooltype.

Anyway have fun with your A2000HD. Getting rare. What was the other drive, and how was it mounted.

Hi

Sorry for misleading the guy it wasn`t intentional I can assure you. I do apologise for making such rash statements, but in the face of someone who is obviously struggling with first Amiga basics I thought it better to be blunt, and try and steer him clear of one or two obvious pitfalls. Anyway you are absolutely correct in what you say, but if you will permit I would like to make one or two tiny observations, which I hope are correct. Feel free to throw anything else into the pot if I`m getting confused again.

You are correct that 2.1 can be used with the 2.04 ROM, as I am sure 2.05 can. Saying that 2.1 was a software update for either 2.04 or 2.05. In respect of 2.05 this was brought out primarily for the A600 to give support for internal IDE and PCMCIA. There were three kickstart versions of the 2.05 and there were issues of drive sizes supported for each. Some A600s were shipped without the 2.05 ROMS and these had no support for hard drives over 40MB. I just felt that in discussing the issues of hard drives it would be prudent to raise the campatibility of ROMS and drives. This way new guys won`t waste time and money trying to fit megga drives to systems that can't take it. As I say, just my thoughts.

My advise from my earlier post should have been more specific in respect of reasoning, and I agree to the inaccuracies but I would still hold that you should use the software that was shipped with the ROM. More of a guide than a rule.

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.

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 ... ?

Anyway, I`m a bit of a newbie to these Forums, and haven`t really got the knowledgebase to advise too much but I would have thought the following would be helfull. It's what I would do.

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.

b: Boot from the Workbench disk for the ROM ie 2.04 to see if the hard drives are being detected and check with the software for hard drive failure with the verification tools.

c: If the drive is causing great problems then Format from the Workbench menu and re-install the 2.04 OS.

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

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.

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.

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.

Cuppa tea me thinks.

Hi

I got A2000s running all manner of OSs from the 1.3 to the 2.1 and with hard drives using an A2090 card along with GVP SCSI controllers with Quantums. I even have two 1500s, each with SCSI controllers and disks. Never had a problem. The A2090 card is actually the A2094 with the auto booting ROMS and thats an actual A2000HD. Nice machine.

The Seagate was just destroyed. It had nothing to do with OS. I have two external SCSI boxes on a 1200 running 3.9 with the 3.1 ROMS but the process killed the drive. I understand the .3 bit not being seen and also have another unit in a tower running 3.1 that has that bit conveniently ignored by the format. You can get round it.

I have all manner of SCSI devices running off SCSI Blizzard kits on three 1200s so I am well versed in SCSI. I also got two systems running on the Squirrel, but I prefer the hardwire to the card to be honest.

SCSI is a very good way to run kit. My A4000T is all SCSI.

Anyway , enjoyed the post.

Hi

I`m sorry its just that you started your post with the statement I bought an A2000HD today. Twenty years, that takes you to the birth of the Amiga and the A1000. So what have you been running all these years. Amazing that you haven`t come across SCSI before.

LLF, is advised in the Amiga manual but every Amiga article I have read in magazines and the like advised against it and I guess other than the odd occasion with a PC drive I have never needed to do it. The drive you have is already formatted to Amiga standard so you really only need to format it through the drop down menu. 40MB is a very small drive so no partitioning will be required.

Check the drive first for errors.

You say faulty. How faulty. Was it making a noise or were there just check sum errors. I`ll have to scan through your posts. If checksum errors then just format as I say.


Workbench Release 2.04 , v37.67 (Kickstart v37.175)
Release date: Late October 1991 New ROM (512KB) and software
Shipped with the Amiga 500+, 3000, and available as update

Did you get the drive working under 2.04 ?

With regard to the software that came with the A2090 and a and b  versions ( A2094 ), it preps the drive in respect of the card. Bit like Faaastprep on the GVP Series II SCSI controller and drive. SCSI devices have to be mounted and this software will set up your Amiga to do this. The HDToolbox can be modded to read SCSI devices specifically by setting the Unit Address number and Even LUN to search for.

Sorry, if I offended, but there was no way I could have known you were an Amiga veteran from your post. Again sorry. I`m no veteran I`ve only been using the Amiga since about 1992, but I do have a version of pretty well every model.

All the best. And have fun
