I’m trying to install the ATI drivers for my GPU and when I try to install the driver, it states the installer is corrupted and won’t install. (Because the MD5s don’t match) I’ve downloaded the files on both Windows Vista and Mac OS X (10.6.6), multiple times, and they always returned the same MD5. When I copy the drivers over to BackTrack 4 rt2 it returns a different MD5 than what windows or OS X returns, and the install file says it expects a totally different MD5 than what either BT, OSX or WIN returns.
I don't know if I'll be able to help any but I'll give it a shot. If by MD5 you mean Message Digest algorithm 5 then we're on the same page.
MD5 digests have been widely used in the software world to provide some assurance that a transferred file has arrived intact and correct. For example, file servers often provide a pre-computed MD5 (known as Md5sum) checksum for the files, so that a user can compare the checksum of the downloaded file to it.
If the MD5 doesn't match then that means the file has changed in some way since it left the person who distributed the file. Something is happening at some point between the server and you that is corrupting that file.
It sounds like you already know the MD5 value. You would have to find a method (example) that runs on Linux to check the MD5 value there; perhaps you know that too. There is no reason the value should ever change regardless of OS. It will only change if the file content has changed.
Update! I ran md5sum in backtrack on the file and it returns the same MD5 as Windows and Mac.
Windows, Mac and BT4 all return this MD5:
30abf0d2d6f19606e396ddb687183550
When I run the installer it says there’s an error in the archive cheksum and says it’s:
48c2e8ce1f504f07a0985afe489b26e3
And the installer is expecting this one:
dfc5d2753d97882b67eb453b85ff8dbc
Could my flash drive just be bad... And corrupting my data the same exact way every time?
You could easily check that by copying the file back to Windows and re-checking the value. I can't believe it would change the file. I have no idea where you can go from here. Could there be a different install file for BackTrack (I'm not familiar with it)? Otherwise one would have to suspect the installer is at fault.
