I just tried to install the newest nightly build hrev39648 Gcc2 Hybrid on my hard disk after successfully booting and using Haiku in Licve CD mode.
My target system is the notebook Samsung R40 Plus Intel Core Duo CPU 2 GB RAM ATI XPRESS Radeon 1250, 120 GB SATA HD and a DVD drive with these specifications: DVD-Super-Multi Double Layer, 5x DVD-RAM, 8x DVD±R 2.4x DVD+R DL, 4x DVD±RW, 24x CD-R, 10x CD-RW, 8x DVD, 24x CD.
Sadly, while the installation is in process, I get the error message "General system error" when trying to copy the file cprivmsg.txt (file 53 of 11894). The installation stops and fails.
I also tried to install the nightly build haiku-nightly-hrev39663-x86gcc4hybrid-cd. The same problem occurs.
In both cases I burnt the CD-Rs with the recording software CDBurnerSE version 126.96.36.1992 medium speeds and the burning software successfully validated them. The CD-Rs are from two different brands. I never had any problems with these CD-Rs and I burnt dozens of them in the previous few years.
The CD-Rs were burnt on my main system that uses the ATAPI DVD Recorder Drive HL-DT-ST DVD-RAM GH22NS30. I never had any problems with this drive in past.
Then I burnt the nightly build haiku-nightly-hrev39663-x86gcc4hybrid-cd again. This time I used the recorder software Nero 10 Trial instead of CDBurnerXP. In this case there are no installation problems. Haiku can be installed without any problems. I used the same hardware. The only difference is the used recording software.
Then I created MD5 checksums of all files by using the tool FastSum on both CD-Rs. Then I compared the checksums with the TextDiff feature of the tool PSPad. There are no differences! All MD5 checksums are exactly the same on both CD-Rs, althought one CD-R does not work (copying of the file cprivmsg.txt fails during the installation process).
Then I created the iso files of the two CD-Rs by using Nero 10 Trial. The iso files have different sizes: Original iso file (haiku-nightly-hrev39663-x86gcc4hybrid-cd): 415.782.912 Bytes Recreated iso file 1 (iso-file-1.nrg): 416.090.268 Bytes THIS ONE WORKS. Recreated iso file 2 (iso-file-2.nrg): 416.094.364 Bytes THIS ONE HAS THE PROBLEM. The three MD5 sums are also different.
The difference between the sizes of the two iso files is equivalent to 4096 bytes. It looks like it could be one block.
Therefore I tried this here:
copy iso-file-1.nrg Image.nrg dd if=Image.nrg bs=6144 count=67673 | md5
del Image.nrg copy iso-file-2.nrg Image.nrg dd if=Image.nrg bs=6144 count=67673 | md5
Now the ckecksums are exactly the same for both files.
By the way, perhaps this problem has the same reasons as this here: http://dev.haiku-os.org/ticket/6723
