My company uses QNX as the OS under our server platform, and we ship out a
few machines a month. Historically we have always used HDDs under 4G and
under 1024 cylinders under the BIOS settings. But now HDDs that small are
getting hard to find and when we do they are used. I must investigate
whether we should be concerned about using HDDs greater than 4G and/or 1024
I was able to successfully install and boot, reboot QNX several times on a
15G drive. It only could see an 8G partition (which is what the support
site indicates), which is fine. But I had to define the drive as having
1871 cylinders, and the support site says you must have <=1024 or you can’t
boot. Was I ok since it was only using a fraction of those cylinders for
the 8G partition?
Can anyone answer these questions:
- Will I experience problems if using a >8G drive but only an 8G partition?
- Will I experience problems if using a >4G drive and partition?
- If I must stick below 8G or 4G, does anyone know of vendors who still
sell these new?
- What are the best brands people have worked with? We like Western
Digital, but do others work well?
- Any other words of wisdom on HDDs and partition sizes?
