Just bought an ex-leased IBM computer with 80GB of HDD - it works fine.
Checked the hdd disk details from Computer Management -> Disk Management which shows the following:
Disk 0 Basic 74.54 GB Online; IBM_PRELOAD (C 29.53 GB NTFS; DATA (D) 45.00 GB NTFS.
Device Manager shows it's a Seagate ST380811AS 41N3267 LEN - HDD.
What is this 74.54 GB Online?
