This might be too late to help you... but did you have a disk in the A: drive when you chose it? If you don't have a disk in the drive when you choose the icon, you will get the message "A:\ is not accessible The device is not ready.. No, it is not absolutely necessary to format the harddrive when you install a new harddrive. It makes things easier if you do, but you don't have to.

(Motherboard: Intel D845WN Processor: 1.8GHz Pentium4) Everything is working great except the A:\ drive (3.5" floppy) is not responding. I tried inserting the cable in every possible orientation but to no avail. What could be wrong. When I choose the "A drive" icon off "my computer," it tells me that the drive is not ready/ not accessible. Also when installing a new motherboard, is it necessary to format the harddrive? > Thanks, > Mike Fixler The NOSPIN Group is now offering Free PC Tech support at our newest website: http://freepctech.com
