Forum: UltraISO Topic: Corrupt files after replacement started by: tim Posted by tim on Jan. 29 2005,15:43
This has happened a few times now.A file replaced within an ISO will be corrupt when read from the final CD. If I rebuild the ISO from scratch (so no files are replaced/updated) then the final CD is fine. This is what I was doing: I created a BartPE bootable CD, see here : < http://www.nu2.nu/pebuilder/ > I have that working OK Then I decided to follow this article: < http://www.911cd.net/forums/index.php?showtopic=10482 > It involves replacing the RAMDISK.SYS within the BartPE ISO previously built (and working). I did this with UltraISO and saved to a new name. When booting off the final CD I get this error: > The file ramdisk.sys is corrupted. So I went back and re-created the ISO from scratch, making sure all the required file versions were already present. This produced a working CD. UltraISO is version 7.5.1.965.

Hello tim,Just tested it this way: 1) Download latest version BarrtPE 3.1.3 from < http://www.nu2.nu/download.php?sFile=pebuilder313.exe > (California selected) 2) Setup BartPE, run it, select a Windows XP SP2 CD as source, and generate an ISO image (pebuilder.iso) 3) Download Windows 2003 SP1 RC from < http://www.microsoft.com/downloa....ang=en, > got srsp1.exe 4) Extract ramdisk.sy_ from srsp1.exe, expand to ramdisk.sys, 22,528 bytes 5) Open pebuilder.iso by UltraISO, replace ramdisk.sys by the new file, click 'Save As' to get a new ISO image (pe2.iso) 6) Test pe2.iso by Vritual PC, it works UltraISO version: 7.5.1.965 Posted by tim on Jan. 30 2005,07:21
WTH?I did it all again and it worked OK. This has happened before, I think I have mentioned the problem in a previous post somewhere. Wish I knew why that has happened (now and previously). |
