Copying Backups to USB External HD

My laptop won't give me a validated backup image when I backup to my external usb (works on my pc). Always corrupt. However if I back up my c: to my c: on my laptop I get a validated image. So, if I now have a good image on my laptop, can I then transfer it (cut and paste) to my external hd, and if I need it will it then reinstall from my external HD? I guess a good way to test it is validate the pasted image on my external Hd.

I have come to the conclusion that my laptop USB does not talk well to my external HD and always gives me corrupt validations. However when imaging on my laptop I get validated images. So I was thinking this may be a work around. Once I get my laptop up and running I'm gonna try this.

I have two external HD usb that work perfectly with my pc, but don't with my laptop.

Any comments are appreciated.......thanks

 

From reading the above, and the comments you've made in various related threads, it seems that the problem is likely to be caused by the chipset associated with the laptop USB ports.
It might be worthwhile getting a PC card with USB ports (make sure you get one with NEC chipset) as I expect it should work.
You should try the cut and paste of a .tib file (or other large file) to the external drive using the existing laptop USB connector. Use a checksum utility to compare the file on your laptop C: drive to the copied file. You may find they are different, particularly if you copy a very large file. Also try this on your PC to confirm that there is no checksum discrepancy using the PC.
Incidentally, did you see my comment in one of the other threads about a BIOS issue with some Toshiba Satellites?

 

Yes I think you are right I have found a couple PC cards with USB ports, and I made sure they were NEC chipsets........gonna order one. I hope that solves the problem. Additionally, I did see your comment about BIOS and Toshiba, it did not apply to my machine. But thanks so much for you help and advice.

BTW why NEC

 

It's just that it's a well known reputable brand, recommended by many people and I've never heard of any problems with USB external enclosures which use the NEC chipset.

 

Just to clear I'm thinking of this one I believe these to have a NEC chipset..

anyones opinion?

 

Don't know about the chipset in the iogear product but the weblink for the syba product says it's an ALI chipset (don't know if good or bad).

Note that both have DC plug to allow for extra external power.
However, they don't seem to have any power cable.
Some disks, particularly faster 7200rpm disks, need more power than can be provided through the PC card. Some PC cards come with a cable which can be plugged into the laptop USB port, thus getting the extra power without having to have external power from a fixed power point. Useful if you are on the road and want to use the external drive.
