For any Mac since hte original iMac:
1. A SCSI hard drive.
2. A PCI SCSI controller
3. An available PCI port
SCSI controllers from Adaptec should have Mac OS binaries available.
For any Mac prior to the original iMac:
1. A SCSI hard drive.
2. If using a non-Apple drive, a third-party formatting utility, or a patched Apple one.
Most brands of hard drive will work with a Mac. If you want to run both Mac OS X 10.6 and 10.7 you will need to partition the drive and install a separate operating system into each partition.
I'm not quite sure what you mean, so I'll give you both answers: "How do you use a hard drive for Mac and Windows on the same machine?" On a mac, insert a Windows install CD or DVD, and the computer will ask you if you want to set up windows to run alongside mac. In the process you will partition the hard drive, so you will kind of have a windows hard drive, and a mac hard drive, but on the same disk. "How do you remove a Mac hard drive and put it in a Windows machine?" I am not a technical expert, so you might want to look up "How to remove and install a hard drive". All I know is it probably won't fit, so you might need to buy a hard drive enclosure and run the drive from a USB port. Hope one of these helps! If not, please revise your question
There is no such thing as a "Mac" or a "Windows" hard drive. From a technological standpoint the hard drives found in Macintosh computers and those found in computer running Windows are identical. Any hard drive with the corresponding interface (SATA, IDE in older Macs, and most SCSI drives in really old Macs) can be used in either computer. The partition table and file system used by each operating system is generally not readable by the other, but the hard drive itself can be formatted and repurposed.
Yes you can have the Mac OS on one drive and Windows on another drive. Or you can partition a single hard drive and have both on the same drive.
The hard drive will need to be formatted (rather than completely blank) and then Tiger can be installed on it.
You can rely on Mac system CD or a Mac Eraser to freely yet securely erase a Mac hard drive. See resources link.
Yes
Just drag the movie to the hard drive icon and it will copy it.
Yes, as long the hard disk drive is not NTFS formatted.
You can learn to do Mac hard drive recovery at Disk Drill. Hard drive recovery can be tricky, but Disk Drill makes it easy and simple. They can help you get your data back quickly.
Any Firewire hard drive is best for a MAC. You can get either an empty one and install the software yourself or can buy the external hard drive with software pre loaded.
Assuming the entire Mac, as in the hardware is dead, you'll need to take out the hard drive and put it into a different computer, put in a Linux disk, and boot up, assuming it wasn't the hard drive that died.
