Re: PCem has bug in ATA HDD geometry
How did you know if the ATA HDD CHS geometry is not handled correctly?

Re: PCem has bug in ATA HDD geometry
Would you care to say what this bug is? Your post is probably the most vague bug report I've ever seen.
Re: PCem has bug in ATA HDD geometry
I suspect the driver the user linked to is simply too new for PCem - it seems to be a driver for 21st century hard disks, not for the 1990's hard disk PCem emulates that is supported out of the box by all of the OS'es listed on the driver's page.
Re: PCem has bug in ATA HDD geometry
This driver is default in ReactOS. And ReactOS works in PCem

Looks like PCem sets Current Sectors/Heads to zero in HDD identify block.SarahWalker wrote:Would you care to say what this bug is? Your post is probably the most vague bug report I've ever seen.
This caused div-by-zero exception.
Re: PCem has bug in ATA HDD geometry
It's still a bug in ReactOS, since the ATA standard has a flag in the identify block that tells whether or not the current sector/heads values can be trusted to be valid. ReactOS seems to completely ignore that and just assume those values can be trusted to be valid. I'd file a bug report with ReactOS, and point them at the ATA standard.

Re: PCem has bug in ATA HDD geometry
You're not seriously asking Battler to go file the bug report, are you? What possible reason could you have for not just doing it yourself?
Re: PCem has bug in ATA HDD geometry
I am 100% serious.
Probably Battler knows this thing better than me to submit more accurate report than I could.

^ lol.
Or you can do it yourself and point them to this thread if you want, it's not a PCem issue.

Re: PCem has bug in ATA HDD geometry
I can not because, I am not fully familiar with information Battler was talking about.
