Hello Jonas, I recorded the newest nightly build r39663 GCC2 Hybrid on a new CD-R disc. This time the disc is from HP and verified it after the recording. The previous one was from Maxell. Again, I get the general system error, but this time when copying the file RFC1459.txt, that is file 58 of 11922. Before I started the installation, I had deleted the Haiku partition on my hard disk and created a new one. This means that the problem is not a corrupt file system on the target partition. The CD-R source disc is also not the problem. Of course, it could be that the DVD drive is damaged, but I do not think that this is the case. I used the same hardware for the old installation a few months ago and the drive had no problems with any CD or DVD discs in the previous few months. Therefore I think that there is a problem in the new nightly builds and we should open the closed ticket. Regards, Miroslav Stimac -- GMX DSL Doppel-Flat ab 19,99 €/mtl.!
