since you're the expert, perhaps you can tell everybody what that
connector is called that is used in the hotswap drive bays
- the connector that goes on the disk
- the connector that goes on the drive bay or chassis
and again, there is a silly equivalent thingies for IDE ... i have some
- and again, on the ide drive bays, what is that connector called
- but, the problem with IDE is that the ide drivers is NOT meant to
hotswap and i've seen pepople pulling out disks too .. wonder why
some of them call in a panic ?
- and one can trivially do cold swap of ide disks
or just buy better quality disk drives in the first place
and add a silly $10 fan to keep its operating temp down
( should be about 30C or so ...
( hddtemp will tell you sorta what it is
- and now days, too many vendors playing with ide cables to make
it go out of spec ... from what the ide drivers can handle
