clip Can/has anyone used a 12V lead acid car battery as a UPS for their box? I've got a spare one in the garage and the thought has crossed my mind . . -- Regards, Mick Mick, It can be done but is slightly more involved than just plugging in teh car bat. I have 3 deepcycle batts, set up for my FD base radio and 1 server using a 12V inverter and a trickle charger and just running the power through the inverter and batt all the time, that way I did not have to set up s a switching mechanism that would switch it over. It works well as long as you get a good inverter and one that is sized correctly for your power requirements. Mike -- Michael W.

Due to the fact that your machine didn't boot but data is available, I'd think your old HDD isn't corrupted but the partition for /boot or the MBR itself. Try to setup grub for your old HDD too. Maybe you'll have a HDD more now. ;) Just a thought Frank -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] Copying between hard drives potential newbie question
Hi people MANY thanks people for the advice, after some painful time I have got my system back or at least everything seems fine so far [typing from opera in X]. As a record for myself and or others who may ever need this I performed the following steps 1. Beat head on wall for not thinking to buy a UPS. 2. broken drive would allow access to data but bios fail reported at attempt to boot 3. installed new drive as master old as slave 4. booted via liveCD 5. Created new partitions and filesystems similar to old 6. mounted new and old partitions 7. cp -prf /old /new 8. chroot /mnt/gentoo /bin/bash 9. grub-install /dev/hda 10. reboot 11. cheer Had a few recommendations for rsync -a and a few concerns that cp would not cp .files or maintain sufficient permissios etc but I think that cp -prf has managed to acheive the same. thanks again stu On 9/1/05, Neil Bothwick [EMAIL PROTECTED] wrote: On Thu, 1 Sep 2005 18:06:38 -0500, John Jolet wrote: dd if=/dev/hdb of=/dev/hda bs=4096 will that get the mbr, or does he still need to do the grub-install step?
