in my xp machine i installed 300gb of hard disk as an additional storage drive. (note: this is just for storage no OS installed in it)
Two HD installed C: and D: The C: for the xp OS, and the D: for the 300gb (storage) the maker is MAXTOR.
innitially the D: was visible with the full capacity. but as a result of another problem i needed to uninstall and reinstall XP service pack 2. After this, in the windows explorer the D: drive is now only showing 10MB instead of 300gb.
Moreover in the Disk Manager I can see D: with 300GB but then it shows the D: partitioned into two 128GB (showing healthy/active) and 152Gb (showing unallocated).
In this case with window explorer when i open the 10MB nothing is there (even though i have huge files there before).
I need to regain this drive fully and have it as before, how do i go about this please?. Maxtor website simply did not help with all the downloads I've made from there

when you install service pack 2 was the d : already formatted ? If not may windows can do the formatted
I ask this because when I buy my machine with no OS on it I have to format the drives first
If windows can not the the job then you need partition magic or some thing like it
Some linux os can format it after it


Hope this use full for you

i'm now suspecting another thing. after the XP sp2 uninstall/reinstall, this 300gb automatically converts itself from NTFS to FAT format (i guess this happened during the uninstall time).
as fat format cannot read large HD like 300GB, i decided to reconvert it back to NTFS but below is the error message.
how do i successfully convert it back to NTFS?
please note that presently the data content of this R: drive is only 80GB, but when i attempt to convert it, it says insufficient disk space for the operation.
how do i successfully convert this?
the 300gb is R: while C: is the boot drive.

C:\>convert r: /fs:ntfs

If at this you only have windows xp may be partition magic or some free ware just like partition magic may do the job


all the best
