Could you 170 Mb drive be having stiction problems? It is said that over long periods of time the lubercant that is on the drive platters can cause the drive to stick to the platter. "Stiction is also known to cause read/write heads to stick the platters of the hard drive due to the breakdown of lubricants which coat the platters themselves. In the late 1980s and early 1990s as the size of hard drive platters decreased from the older 8" and 5.25" sizes to 3.5" and smaller, manufacturers continued to use the same calendering processes and lubricants that they had used on the older, larger drives. The much tighter space caused much higher internal operating temperatures in these newer smaller drives, often leading to an accelerated breakdown of the surface lubricants into their much stickier components. When the drive was powered off and would cool down(say at the end of the day when a user went home and shut off their PC), these now-broken-down lubricants would become quite viscous and sticky, sometimes causing the read/write heads to literally stick to the platter. The common solution to this problem was the counter-intuitive move of taking the affected drive out of the host system, striking it gently, but firmly on the side against a desk or something as laterally as possible and then re-install it in the host system. This would break the heads free of the goop long enough to power the system back on, have the drive spin up and recover whatever data could be retrieved off it. While the data was retrieved, the machine would be left on constantly so that the heat from the drive's internals would keep the decaying lubricants in a liquid state." http://en.wikipedia.org/wiki/Stiction -- V/R Mark Frischknecht si vis pacem, para bellum http://www.appleiiguy.net Apple ][ Forever!
