ATTENTION!!!!!!!!

 

1. If you do not have a minimum of 400mb, forget about all checking routines and repairprograms, because the G5 need discspace to save temp data on this drive - SO YOU NEED FIRST A BIGGER DISC FOR BACKING ALL UP - PLEASE!!!!

 

2.You have to be very careful with all the things i explain later on - and be patiant things need time, don´t stop any proces till it ist finished.

 

3. Data recovery programs can only bring data back wich are known filetypes for them, so if you choose the wrong tool, you destroy more data...

 

4. First go into the Harddisc Reoair Program which is delivered with OSX.

Look at the bottom of the window if you choose the seagate - there is a field called s.m.a.r.t status - if there is a error or it is written in red or you find unknown - we have a serious problem - the only tool that might help is tech tool pro.

Keep in mind that you have to check the right versions for tech tool pro and disc warrior, because you are on OS10.4.9, don´t use disc tools which you used for 10.4.0 or 10.3... it will damage yor file system (no spotlight, other metadata).

 

5. If you use tech tool, rum the complete procedere concerning file checking and dont stop the processes until they finished.

If tech tool stops with an unknown error or the ball starts spinning you have to quit and start again.

If tech tool succeded start again, you will see there are errors left - a defective smart status is a hardware problem causes a couple of header mistakes on your drive.

 

6. If your smart satus is ok, than you might have a distroyed catalog b tree.

You can check that if you start the G5 in the verbose mode - press v right after the boing start tone and than watch the boot up sequence - relativly at the end you can see the disc checks, if there are catalog B errors on the disc use disc warrior.

 

But first get another bigger drive!!!!

Good luck

There is nothing called the Hard Disk Repair program. There is a program called Disk Utility in the Utilities folder with the applications folder.

And now it's time to read, and implement, Lisa's excellent advice!

 

The minimum workflow/backup is SD/CF card to computer (external FW drive, for example), then immediately to DVD; the full unaltered copy of whatever's on the cards. Never vary this step!!!

 

If the work is critical (a paying job, rather than snaps) then make a second DVD from the same original. The second DVD is kept at another location.

 

For me, this is sufficient.

 

Re. maintaining computers: now you have the latest version of Disk Warrior, make sure you use it. I use mine once a month if I am using the computer daily.

 

Augment this with Cocktail or another utility program; run the CRON scripts and log rotation utulity AND repair premissions weekly. hth, kl

Also, check both DVDs after you've made them to be sure you can access the data. Yes, this is a pain in the butt, but nothing less will do.

Russel; excellent point. I have my copy program set to mount any copied DVD/CD immedately; I then click on an image file; I assume that all is OK, copy-wise, if it opens.

 

If you want to be 100% sure, the set the program to do a full byte-by-byte verification of the copy. Takes longer (about the same time as it takes to burn the DVD) but is the only way to be cmpletely sure, cheers, kl
