I was running win 98 with a 20Gb HD partitioned into 3 drives;
C:\ 10 G b
D:\ 1.5 Gb
E:\ 8.5 Gb
For the past few weeks I had noticed that space on D:\ was being reported wrongly, and even when there were no files on it, it only had just over 700Mb free.
I tried formatting it (D: drive) by right clicking in Windows explorer and choosing format, but windows said that another application was accessing the disk and needed to be shut down.
Because I couldnt work out what this was, I booted from a 98 boot disk and formatted it at the dos prompt.
Firstly i ran "format d:" then cancelled it after 2 percent and ran "format d: /q"
When I restarted my computer, I got the "Invalid System Disk" error
It appers that D:\ had not been formatted, but C:\ had been formatted to 1.5 Gb !?!?!
I have run some diagnostics on it, and tried a couple of utilities to recover my C:\ drive.
When windows or DOS looks at the partition it only sees an empty 1.5Gb partition.
When I look at the Disk itself in partition magic or Disk Management in NT then it sees a 9.8 Gb partition with 8Gb used.
A recovery tool I tried picked up some stuff (inc an empty folder structure) but couldnt read past 1,500,000,000 bytes.
SOMEONE PLEASE HELP ME, i only really need to recover the My Documents folder, and my email. Everything else i stored on the other partition.
