Disk I/O Error - please replace

Jan 29, 2005 11:25AM PST

I'm tring to fix this drn. 75mhz computer. I get this error. Disk I/O error please replace. It works fine in my other 2 machines wich are a little faster. The cmos of the non working machine reports a HD size of 426, but it reports a size of 406 in the 2 working machines.

Also....I tried a HD out of one of the working machines, in the pc thats not working right...and it works fine.

Help me if you can! lol

How is the drive recognized

in the non working machine? Is it autoconfigured or manually configured? LBA or otherwise?

LBA mode ect...

hard drive from bad machine works in other 2 machines....and hardrv from 2 good machins works in bad machine...lol

anyway, LBA does not have an "off" setting, but it has a "LARGE", "LBA", or "Auto" setting....i've tried them all with no luck.

I've tried to "Auto detect" HDA, and "Manually configure" according to the settings I got from my 2 working machines....This is where I discovered that the size reported in the working machines "406(Mb)" does not match the size reported in the non working machine "426(Mb)", even though everything (number of cylinders and heads ect...is set the same in all machines. The only manual setting thats different is the LBA mode wich is set to "off" in the working machines but "auto" in the nonworking machine because it doesn't probide an "off" setting.

One possible reason for the size discrepency

426x10^6 (426 Million Bytes) = 406x2^20 (406 Megabytes)

Different people report Megabytes differently, mostly disk manufacturers use 1M=10^6.
