I recall a thread like this before the forums were lost - unfortunately, I paid little attention to it.
I've currently a 40GB, split into two partitions: 10GB for the OS and the rest for files, games, etc. Both are formatted in NTFS (Yes, yes, smaller cluster sizes, etc., etc.). However, I'm reconsidering after what happened yesterday.
While copying files from my older harddrive to my storage partition and browsing the pifast times chart, my computer hung (Overclocked too high, not enough voltage). Tempted by pifast (It tempts me to overclock higher. ), I kicked my JIUHB up to 2.5GHz, booted. Win2K, of course, froze soon after it finished loading, so, with a sigh, I went back, restored my previous overclock. Getting back into windows, I find that the storage partition, onto which I'd just copied over 15GB, was gone. Explorer lists it as "Local Disk" instead of the label I gave it. Click on the drive icon, it's tells me the partition is either corrupt or not formatted.
Now I'm worried that after I've completed copying everything from the old drive and formatted it, one of my partitions will again spontaniously corrupt. Was it a freak accident, or is NTFS potentially this unstable? I'm seriously wondering if I should go back to FAT32.
