EIDE cables Master Slave

I have seen windows 98 or 2000 let the bios decide what to use without checking and causes a lot of data corruption. That was back in 2001 so not sure about today's implementation. Heck, PATA hasn't been the mainstream since 2007.

I don't know why the drive-side 80-wire cable detection failed, it's an 80 wire cable. But it's an old 10GB drive and I really don't care as long as it works (it's going to be used for an Asterisk PBX).


Is the cable cut? I think I cut an 80 wire cable once and it wouldn't detect as 80 wire anymore.

You are correct. I was thinking about PIO vs UDMA on the same cable.

It's possible that there's something wrong with the cable. Physically it looks OK, but I scavenged it out of an old Dell, most of the rest of which went in the trash.

I really need to order some new PATA IDE cables from Monoprice...

I've seen that work OK too

Of course it was Windows dictating PIO, the BIOS had stated DMA, turning it on in device manager yielded MW DMA 2 on the CD-ROM, UDMA5 on the HDD.

Are they available with PATA interfaces?

WD Caviar Blue (just one example): 972Mbit/sec

Wow, didn't know that, I was having problem with this back in windows 95 days.

Well, DMA on a lot of stuff, particularly non-Intel chipsets was suspect in the Windows 95 days. Lots of things that would lead to data corruption with the enabling of DMA if one was not careful. I recall certain VIA and ALI chipsets that would cause data corruption if you enabled DMA in conjunction with certain hard drives.

Man things have improved a lot since then.

By the by, we cannot use the terms "master" and "slave" when referring to computer cables in L.A.:

Old news, I think the suggester got re-educated in the area of computer technologies and withdrew the suggestion.
