My harddisc drives and CD drives keep disappearing!
It all started when I bought a brand new computer a couple of months ago. I tried to re-install my tried and trusted Win98SE but found that my new machine couldn't do it. (Apparently the machine was "too powerful" to support Win98SE.) So, very reluctantly, I was forced to install WinXP.
The WinXP instalation went smoothly but within a week it had crashed because of "hal.dll" and I was completely locked out. I was unable to re-install it using the install disk so I thought I would wipe the disk completely and start from scratch. However, I found, with help from DOS, that both hard disks and both CD drives were no longer recognised. Furthermore, as a result of using fdisk and formatter (100% partition), that my main disk had been changed from NTFS to Fat32.
To cut a long story shorter, I got this sorted out by a call-out engineer who used his own install disk. However, last week my CD drives disappeared again. Luckily I was able to get them back again using a backup.
The crux of my question is this: Why do CD drives or hard disk drives disappear? What causes it? And how can it be reversed if no backup works?
