I regularly get calls from friends... "I hozed my system and it won't boot." Ok, just restore the backup. I don't have a backup. Why? Because my drive is a single 500GB partition and I don't have any place to put the backup. And it would take three hours to do and I'm a busy person. Let me get this straight...you're too busy to back up your system, but you think I'm not too busy to try to recover your system???? I have a 16GB windows7 partition and two more 100GB partitions. I put all media files, databases, maps, everything that is archived, easy to reinstall, or otherwise duplicated on D. I can use Acronis to image up C to E in about 10 minutes while I'm using the system, although I usually go have coffee while it's happening. Then I copy the image to the backup drive over the network. I typically have months of backups on hand. Try that with a full backup of a gigabyte drive. And I can copy the root partition to a 40GB drive and quickly have a system that I can experiment on without risking the primary system drive. Comes in really handy when trying out freeware that's really spyware. I can recover from a hozed system in about 10 minutes. Takes a little longer if E is hozed and I have to copy the image from the backup drive. No reinstalls, no license codes, no registry hacks, no reconfigurations. It's right back where it was. The time to plan your backup strategy is before you partition your hard drive. Image the root drive...make it as small as you can.

Make sure you find out what the internal connector is for your 2.5" hdd (IDE or SATA) As an example. With these drives you would need to purchase an additional power to USB cable, but it should certainly work if you have two USB ports available and one to use for a mouse. This one has an internal SATA connection. http://www.newegg.com/Product/Product.aspx?Item=N82E16817145329 -- Jan Alter bearpuf(a)verizon.net

Image the root drive...make it as small as you can. > Copy files from the other partitions to back them up. Agreed. I do the same thing. I also change the path for 'My Documents" to a folder on another partition so 'users' who save everything to My Documents don't get warnings about the HDD being full. An added advantage is that Windows can't scatter it's files all over half a TB of space, it's kept compact (and easy to defrag if that's your thing [it is mine]) so the drive heads aren't flapping about like albatross chicks come time to boot the machine. If someone who's machine I've set up comes back to me with a hosed install chances are I have an Acronis image of their virgin install on one of my external HDDs (and I would have given them a DVD with it on as well, at least for XP users). It's then the work of less than 30 minutes (more like 15) to have it back as it was when if left my place originally. IMO using the whole HDD as a single C partition with drives the size they are these days is absurd from a security (of data and from malware) viewpoint. (No offence intended Bill.) -- Shaun.

The alternative is to get an enclosure for the ext. hard drive. The Samba brands include a transformer to supply drive power separately from the USB port. -- Don Phillipson Carlsbad Springs (Ottawa, Canada)

The shorter arm contains Vcc and GND only, no data. I've thought all along if you have device not being detected properly because of insufficient power you could double the shorter "y" arm and plug it into adjacent unused USB port to boost the Vcc to gadget. |
