Invisible partition.

By jardinier ·
I have a 3 GB HD which shows only one partition of 500 MB under fdisk. Will a low-level format remove the invisible partion(s) and allow me to access the full 3 GB?

Invisible partition.

by savatovic In reply to Invisible partition.

Hi,

I don't know what is the history of that HD, but it is possible:

a) That it was partitioned on an older version of operating sytem like Win95 (before OSR2) or WinNT 4.0 which does not support FAT32 (ie drives larger than 2GB)or some dual boot system with some sort of NX. In that case your visible partition is FAT16. The remaining space may be unalocated or formatted by a file system not visible to fdisk (like Windows NT/2000 NTFS or Linux Exfs)

b) That it was originaly partitioned with two partitions and one was later deleted.

My advice. Before using low level format, try to add additional partition (and/or logical drives in extended partition). If you want to retain data, you may try to extend partition with Partition Magic or some similar tools. If you can afford to loose contents, you may delete present partition and repartition the disk.
You may also try some other partitioning tools other than fdisk which may recognize other file systems. I use one from Symantec Ghost (gdisk), but I'm sure you can find some alternatives on the web.
