Re: Disc errors when booting latest TC release from a CD

hello
i'm having the same problem here also, since i started
using TC last 2 weeks i just ignore it the first week because
i thought this only happens on my test machine. when i run
on my home computer, it has the same problem. so, I start
wondering. i burned another copy (this time the multicore
before it was tinycore_3.8.2) but it has also the same. errors.
i don't think it has something to do with the hard disk or previous
operating system, because i tried booting without HD, the same
error is coming. yesterday i pulled my old pentium 2 and try to
boot from there, same problem on both cd ( tiny core and multi core.

This is a partial copy of my error messages:

hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
hdc: possibly failed opcode: 0xa0

@ gwalther and ru60hz
Try burning a disc using the directions from this link and see if that helps.

hello Rich,

no more errors!

thanks so much for the advice. so, now i've learned a very important lesson.
although i used cd record instead of rawread and i downloaded the
wrong iso (accedentally downloaded the current version 3.8.4) i think
it should work also in version 3.8.2.

i have not check yet with md5sum because it's too late now in the evening.
i'll do ti tomorrow.

Again thanks,

ruel

Hi ru60hz
You are quite welcome, glad I could help. CD record was the right thing to use. Rawread is for
creating an ISO file from a CD.

You may try libburn.tcz also. It contains command line tool 'cdrskin', a 'cdrecord' replacement.

Yay!

I followed the points in the link regarding burning CDs reliably and I now have a CD that boots OK and a USB HDD that works too :)

I still don't understand why the downloaded ISO produced the errors when used to boot a VM but hey, it is the USB HDD that I need.

Thanks all
Jeff

Hi cast-fish
Please let us know how it works out. It would be nice if all these CD boot errors turn out to be
nothing but CD burn related errors.

@ bmarkus
thanks, i'll try that.

@ Rich
yes you were right, cdrecord is the right thing, i just
misunderstood the statement. anyway i was able to
use rawread for checking md5sum  :)
Anyway, back to the subject. So, it means the real
cause of the problem was because improper iso burning
due cd burner not set up correctly, incorrect speed,
lack of the -dao, -pad or padsize= arguments to the
cdrecording program used and so on which a normal user
like me don't know and maybe some people knew but not
take it seriously.
also, it means IMHO that the latest TC realease is getting better
being able to detect errors that other distribution cannot or
ignoring,

by the way, catfish, i tried also burning using a cd re-writable last night
tried to set it at lower speed but cd recorder is auto. coming back to
maximum speed of 10. i don't know why. and the result is also good.
IMHO maybe you can try again? because here, it's working fine.

thanks
ruel

Hi ru60hz
Just be aware that re-writable CDs have a minimum write speed as well as a maximum write speed.

@ Rich
thanks for reminding, mine is 2 - 10x

@ cast-fish
BTW, did you issue this command also?
'cdrecord dev=0,0,0 speed=10 blank=fast padsize=63s -pad -dao -v -eject'
i think it's needed on a cd-rewritale cd

thanks

Blanking a re-writable CD before burning is probably a good idea.
