I got the above message when I try to boot my IBM 6.4GB Desktar 8 harddisk. I managed to use it for quite a few days before this appear. Initially, the CMOS was able to detect the geometry and capacity of the harddisk correctly but after I try to play around with some boot manager, Linux and NT Disk Administration... this happened. I tried low-level formatting this harddisk with utility from Seagate, Maxtor and Quantum but to no avail. Could somebody advice me on what to do next to bring the harddisk back to life. Thanx in advance.
