I have owned the Commodore Amiga 3 1/2 disk drive since 6-86 without any problems whatsoever. Recently, I have been getting read-write errors even on Sonys' disks.... Amiga 1000 512 k mem amiga live packard bell 2400 baud modem. I am also using 1.3 (since 3 months ago) without any startup-sequence to bypass loss of needed memory. Is there a possibility that 1.3 might be the culprit, or maybe a new virus? recently, I turned off the system, put my original kickstart and workbench in, and re-installed my cli disk and haven't seen any problems since. (Of course, I haven't formatted any disks lately, and that is where the problem usually shows up.)

After several week of really being POed when my sources disk lost the root directory, I came to the realization that the disks were failing when the room got too warm. Since you are in NM (I'm in DE), I assume you are starting to get quite warm dowm there. Try turning up the air conditioning. -- Darren

I have been experiencing similar disk problems for almost a year now, so I don't think it's the temperature. What I have noticed is that most of the errors occur in tracks > 70 when my disk started getting full. I suspected drive speed problems but I checked that and it was in the correct range. I even opened up my Amiga (500) and cleaned out the drive and the problems still persisted. Currently I still have no clue as to what the problem might be. Jason Leigh jal@zeus.cs.wayne.edu

Could be a misaligned drive, or it might be an electronic problem with the drive. I assume you used a head-cleaning diskette to clean the heads. Most errors (media or drive-related, as opposed to software) occur on cylinders 70 or above. This is because the bits are closer together near the inside of the disk, and so the ciruitry/hardware is stressed the most there to work correctly. Does this occur with known good disks (brand-name), or with generic disks? -- Randell Jesup, Commodore Engineering {uunet|rutgers|allegra}!cbmvax!jesup

I have one of those computer desks where it is easy to cut off air flow with shelves. My problems went away completely when I moved a shelf up 4 inches, and let the machine cool down. Second suggestion, use a disk drive cleaner every few weeks or so. I once could not even kickstart my a1000 untill I cleaned the drives. Bill Nichols wn0e@andrew.cmu.edu
