Hi Guys' I have a sata 160Gb hdd as second drv (ntfs) on XP home.I must have had too much wine for dinner as I formatted it & then ghosted my C drive onto it. Unfortunately the C drv is FAT 32. Now the drive ID letter (F has gone. I can still see the drive in disk manager but cant access it. Is there a way of low level formatting it ? I dont mind losing the data. Thanks Manfred. I do have a good relationship with my PC - just a bit strained at times.
