Boots fine but.

Can I get someone who has successfully downloaded puppy-215CE-Final.iso to execute the md5sum command on the mounted cd. Md5sum output on the individual files might be a good thing to make available on the download servers, possibly as a text file on the iso, so a user can verify puppy cd/dvd boot media for errors. IE.. verify reader is reading correctly, cd/dvd not scratched etc.

sh-3.00# md5sum *

Thanks Much

i have suggested putting an md5sum file in the iso, more than once

then you could easily check if each file in the iso or on the cd/dvd is a perfect copy or not

this does not check the entire disc, but it does check 99% of the disc, and it does verify all the files on the disk ... and the md5sum file is not very large

and it can help to check whether a cd/dvd disc burned correctly or not

There is a difference on my machine for zdrv_215.sfs (april 06 17:58 )
What is the date/hour of yours?

My zdrv_215.sfs agrees with Beem's. Both of them that I downloaded. One from the torrent and the other from richard.a's mirror.

Must have gotten corrupted during the burning process or it is not reading correctly because the md5 checksum was correct for the iso. I should have kept the iso but I stored and burned it from RAM. Since puppy only has a handful of files, it could have a copy of the md5 checksum (maybe several copies for redundancy) included in the iso. IE... another plus for using puppy over most other distros.

Again
Thanks Very Much for the information!!!

PS -- maybe the scripts run during the startup process could check the md5 checksums on the core files, then warn the user. Wish I could download just the corrupted file, approx 1/10 the size of the ISO file, then I could fix my problem.

According to WhoDo, at

http://murga-linux.com/puppy/viewtopic.php?p=108734

zdrv_215.sfs is just zdrv_214.sfs, renamed.

zdrv_214.sfs is available at

http://distro.ibiblio.org/pub/linux/distributions/puppylinux/

However, its md5sum is

51d463b8507a7d0391225d00f64c3135

which is different. Anyone know why?

no, i don't think the name matters

basically, if 2 files have the same md5sum, it is almost certain that the 2 files are identical

if 2 files have different md5ums, it is almost certain that the 2 files are different, even if only by 1 byte
