I am using a second boot-drive HDD on my winxp also as external system-partition-backup-location. its an esata with firewire and usb also.

when with trueimage trying to save systempartition 70gb it says writing error. and also telling me chdsk must be made.
Should i attach that drive as boot-drive and doing chdsk then. How? in save mode? would that work.
Should i do to dos-mode and act from there. do i have to know first the related drive-letter.
systempartition-save-location(drive-letter) has different letter when comparing inside trueimage with normal use.
I have a full version of Trueimage recognizing also Seagate together with WD-drive. limited free version would allow the latter too.
If both NON-WD-drives: Full version needed.

NB: Important note for those doing the same. This must be the procedure:
1. first-boot-drive(cd/dvd-drive) must set in cmos first.
2. PC must be shut down then after that, starting from NIL. otherwise drive will not show up.
3. maybe one must start up pc first with external drive activated.
4. maybe cd must be inserted only during second fresh start we will see next time.
