Slave/ master jumpers

[Josie-boy]

I found 2 old disk drives with a ribbon cable. They have a jumper on the back of each with one set to slave and one set to master what is this for?

With IDE, each port can use 2 devices. Setting one to master and one to slave tells each device how to act.

Know that you have to have a master and a slave - you can't have 2 masters or 2 slaves.

How it works:
When the master is transferring data, the slave has to wait for the master to finish. If the master is doing nothing, then the slave can transfer data.

Confirms chanel as ide shares the same bandwidth per controller and boot order (dos seeing a,b,c,d,e drive etc), 'newer' implementations also had cable select which let the bios which drive was on the end of the cable.

Read this

And get a USB key instead of using that garbage.

I am offended.

IDE is not "garbage", and neither are optical or floppy drives.

Neither were

Also all Sharknado movies are masterpieces...

Seriously... SCSI man T'was worth the 400$ for 40 gigs back then.

SCSI is a bit harder to set up - with IDE, you set your jumpers and boom, it works.

IDE's bandwidth is about 33MB's  sure there are quite a few USB keys that can reach or exceed that speed but only the expensive ones really can support that speed without slowing down later on (assuming there is the option to make use of USB 3.0 or later because if we are talking about USB 2.0 only very expensive ones could could be as fast) 

 

but HDDs have the random IOPS advantage meaning an OS for example would be snappier installed on a HDD than on a USB drive. 

 

as for SCSI it was convenient for professional use because its wider bandwidth allowed for more HDDs per controller (instead of 2 for IDE) 

 

So it was the same thing just more HDDs per cable, you could use it for faster HDDs though as well but back then faster HDDs were ones with 10 or 15k rpm or even more... which is not cool to have unless you gonna use it in a server rack somewhere far away from your ears 

 

 

 

And this recording really doesnt do it justice, I remember using an old PC I restored (with a normal HDD) and being baffled by how loud it seems to me now back in the day I wouldnt even notice and think it was a silent PC and that version of me who would think that also thought that 10k+ RPM spinning noises sounded like some squeeky very loud turbofan

If you're just trying to figure out what's on the drives and you don't have a PATA/IDE connector on your motherboard or a peripheral card (and you don't have an older computer with those), it might just be easier to use a USB adapter cable and power supply.  Ex. https://www.amazon.com/AGPTEK-Converter-Switch-Connector-Support/dp/B07PK8ZQQC/ref=sr_1_4?dchild=1&keywords=PATA+USB&qid=1612068069&sr=8-4

Up to 133MB/s.

And there were ide hdd-s which were very close to what we have now in terms of noise and performance for similar sizes. Like i still have 500GB wd blue (WD5000AAKB) in external usb box, and i still use it...
