I am just fishing to see if anyone else with a Tandy 2000 has been experiencing problems with disk errors when the disks are nearly full. I have this problem when either of my drives contain more than about 640K of data. I have had both drives replaced but the problem persists. Is this a problem anyone else has experienced with these high density drives? Or, is it a bug in the device driver for the drives (anyone at Microsoft or Tandy know?) I would also welcome any questions by anyone considering buying one of these machines. My general impressions of the machine are so far very good. The price is great and the machine is much much faster than an IBM-PC. It will run any MS-DOS program that does not directly address the PC hardware. It has some pretty snazzy hardware of its own especially the video controlling chips. You can scroll any window in any direction. You can do smooth scrolls and you can redefine the character sets without adding a new ROM. All this and graphics on a monochrome monitor.

One characteristic of normal constant rpm drives is that the head/media
velocity is fastest on the outside tracks and slowest on the inside tracks.
This means that the chances of having a read error increase as you move in
to the disk. Most OS's start filling a disk at the outside and work in so
you never use the slower inside tracks unless you put a lot of data on a
disk.
