3545.0. "another HARDRIVE problem A2090 + RD54(maxtor XT219" by FRA04::JMUELLER () Mon Mar 05 1990 06:48



	HI FOLKS,

	here another Harddrive Problem. 

	my configurations:


		B2000 
		A2090 and Maxtor-Drive xt2190 (RD54)

	when i tried to format my RD54 i received funny noices from
	the harddrive. accessing the drive after the format results
	in Read/Write Errors for every access.

	the only way to make the RD54 work proper, is to format
	it with 8 READ/WRITE heads. normaly the RD54 should also
	work with 15 READ/WRITE heads. I tried to connect my
	local Commodore Dealer , but nobody could give me an answer
	on homany READ/WRITE heads the A2090 hddisk.device Driver
	can handle.


	is there any idea about this problem. thanks in advance for
	suggestion.


					regards


						Juergen

	I believe the A2090 only supports 8 heads. When you say it has 15 heads, formatting heads 8 to 14 overwrite heads 0 to 6!! Now heads 0-6 have ID fields that say "this is head <8-14>" - Permanent ID NOT FOUND errors. The RD54 makes alot of noise when doing a recal so this is "normal"! John
