Physical switch to disable a hard drive
Which leads would need to be physically opened to take an ide drive out of service?
I tried power, only, but that results in a parasitic flow on data lead(s). Thanks, (to protect hd as backup) |

Which leads would need to be physically opened to take an ide drive out of service?
I tried power, only, but that results in a parasitic flow on data lead(s). Thanks, (to protect hd as backup) I used a removable hard disk enclosure to accomplish the same purpose. The enclosure for removable hard disk has a lock-and-key that I can turn on/off the power of the removable hard disk. I use the removable hard disk to protect the full hard disk backup that I made using Drive-Image. In theory, I can buy another hard disk as a second removable hard disk. Then, I can keep two backups. The downsides a - The enclosure costs money. - The fan in the enclosure is quite noisy. Luckily, I don't do backup that often (may be I should do this more often). Jay Chan |

Very similar, but I'd rather have drive remain in its cubby, switch it
in, boot with special volumes config, run backup, switch it out, and boot with normal volumes config. That's the same as is currently done, except for the disabling switch part. There's also some concern about signal quality, with one or more of the leads considerably longer than the ribbon cable, because of the detour through the switching device. Honestly, I don't really know what you are trying to accomplish. After saying this, if you want the hard disk to be completely isolated from anything else. You can use the removable hard disk enclosure that I mentioned in my previous message. You can use the key to turn off the power of the removable hard disk. If you want it to be completely disconnected from anything else in the system, you can remove the hard disk physically. Then, the hard disk will not even have a IDE connection to the rest of your system. Pull it out slightly will also disconnect it from the IDE connection without completely removing the hard disk. Hope you will find the info that you are looking for. Jay Chan |
