StuffIt Deluxe: Use Commercial Version for Important Work

I use StuffIt 1.5.1 to archive large amounts of data. I made one large StuffIt archive (about 20MB). Later, I extracted and deleted some of the files in the archive, making the size about 8MB. Then, I tried to extract more files, but got the following message: U-uh! The CRC-check for the resource fork has failed. Chances are that the file is trashed. Please use this file with caution. This happens when StuffIt has almost finished extracting the resource fork. That seems reasonable, because that is the time for calculating the CRC. Sometimes, I'll get the error messag above. Other times the machine bombs or just hangs. The message says that one should use the file with caution, but that is impossible, because StuffIt is unable to finish extracting the file. This happens with all the remaining files in the archive. I have tried to delete all files in the archive except one, but that does not help either. I suspect that the error is caused by a media fault. The drive in question is a Bernoulli Box from IOMega, and the error has occurred only on the two cartridges that came with the drive. Later, I ordered at least 30 cartridges from the USA without any problems.
Sorry but we aren't familiar with StuffIt's error handling or bugs, nor are we
familiar with this specific problem. The user might check with the programmer
(name located on program's splash-screen) or the new distributor for any
recovery routines they may have.

We generally caution users against using shareware software for critical work;
you may wish to get the enhanced commercial StuffIt Deluxe. StuffIt Deluxe, a
file compression, encryption, and file-archiving software. It is designed to
compress files (or folders) of all types into compact spaces, potentially
saving 50 to 75 percent of hard disk space. You can also password protection
(DES algorithms) any archive. StuffIt Deluxe works on 512KE or larger Macintosh
running System 5.0 or later.
