Question about old HDD
Hello!
I have a strange question about an old hard drive that I pulled out of an old Pentium 1 computer. The hard drive was working fine, and the computer was able to boot into Windows 95 fine. Then I decided to run SpinRite6 to check if the hdd had any bad sectors. SpinRite6 booted fine from a diskette and detected the drive. Then it refused to do any kind of work from the drive and claimed that the partition size was larger than the drive size indicated in the computer bios. The drive is a Western Digital caviar and its label indicates that it has 2484 cyl; 16 heads; 63 sect; 1281.9 MB. http://e.271828.p.31415.googlepages.com/s_IMG_2558.jpg The computer auto-detected the drive as following: 2484; 16; 63; 1223 MB. This configuration was able to read the drive fine, but SpinRite gives this: http://e.271828.p.31415.googlepages.com/s_IMG_2558.jpg http://e.271828.p.31415.googlepages.com/s_IMG_2561.jpg Then I pulled the drive and stuck it in a newer Pentium 4 computer and it detected it as follows: cyl :620; hds: 64; sectors: 63. Total sectors 2502872 Spinrite ran fine. When I stuck the drive back into the old computer I tried this configuration and got 1221 MB. http://e.271828.p.31415.googlepages.com/s_IMG_2560.jpg The computer also booted up quite fine and made it into windows. Spinrite still did not want to run on it and claims that only 619 cyl are specified. http://e.271828.p.31415.googlepages.com/s_IMG_2562.jpg What is going on? I have extensive experience with modern hardware, but this is my first experience with such old hardware. Can somebody please explain or clarify what is going on: How can the harddrive be detected fine with 2 different configurations, which one is the correct one, and why does Spin Rite read the drive on the newer computer but refuses to read it on the old computer with either of the 2 configurations. Thank you! |
