help! disk is not a valid DOS partition.
« on: January 05, 2004, 02:37:20 PM »
hey people, i have a little trouble with a hard disk and need to recover files.

the background:-
i did have an A4000T PPC blah blah blah, and before i sold it, i backed up all my files to an IDE drive, (FFS boot partiton 100Mb, FFS main partition 4.8Gb)
put drive (OS 3.5) into A1200 (3.0 roms) reloaded 3.0 OS on the the system partition.
started having issues and disk errors with the main partition (4.8Gb size). tried to run various disk tools to get some of the directory structure back as i was missing a load of driectories with drawings and technical schematics, pin outs, board designs etc.
ended up running quarterback tools. came up with a load of date errors, fine as it thought the date was 1995, and the A4K having an onboard clock had a date of 2003. so it thought the dates were in the future.
spent ten hours doing a disk block scan, all ok, directory date check all fixed. rebooted.
disk didn't boot.
didn't even show partitions in the early startup menu.
booted off of floppy. no hard disk partitions. ran hdtoolbox. disk appeared fine, went into the partion window and it was showing me the default new disk layout. two partions of roughly equal size.

have i lost everything? my drawings? my pin out listings? my signal traces? all my bought and paid for shareware enabler keys for Mui, SoftCinema, IDEfix, etc? all my apps? is there anything i can do?

if quarterback has lunched my disk then thats it. i have given up with Amiga. no more 10hour disk surface scans, no more mangled directory structures to be put back together by hand,
i've just run out of patience.
or is there something i can do to save it?

disk salv wouldn't have anything to do with it as i didn't have enuff memory to run the requested operation. and yes yes i know i should have had more than one partition for apps and data like i did previously, but i just did one backup to large partiton.
i know all the things i should have done. like not sold my A4K. but is there anything left i can try?
btw, my DDS2 tape drive and backup tapes went with the A4K. i have a couple of DDS2 drives left, but no tapes.

i consoled myself by putting my pc back together and watching a few bad quality futurama episodes before going to bed

A500, A600, A1200x3, A2000, A3000, A4000 & a CD32.
and probably just like the rest of you, crates full of related "treasure" for the above XD

thanks. i thought as much, i just wanted confirmation, kinda like the doctor giving a verdict and you want a second opinion. all that work over the years... i thought by dropping the filesystem version from 45.1 (OS3.5) to 39.x (OS3.0) i would be ok, and keeping everything within the 4Gb boudary. i used to run that drive no problem in my first 3.0 based A4K. sigh. thanks again, and take care people.
hope amiga lives on in some form or another.
sleep well, signing off.
