I'm using a brand-new Maxtor 8760S as System Disk for a Sun3/50 running SunOS 4.1.1. On building X11R4 it became evident that the data read from disk was faulty from time to time. Already when cat|uncompress|tar-ing the distribution, tar exited with checksum errors at different locations. Checksums built over the files several times showed different results almost each time(for the same files), among them the "should-be" ones (using both bsd sum and sysV sum). Trying again and again it finally got unpacked. Next to die was the make over the distribution. Though no read errors were reported, files read different at each try. "sane" programs exited dumping cores one time and went through on the next try. Among them makedepend and cc (iropt). cc exited with syntax errors one time, passing by next time. Some header files had "stray" characters in them causing real syntax errors. After they were corrected (and some restarts of make -k) finally the Release was built. It took 5 runs of make to succeed on all targets. I tried the disk in another Sun3/50 environment with the same results. During "normal" use everything looks alright. Fsck usually remails silent. The Disk is reported to have 192 bad blocks, one more having shown up a few days ago. I build the release from the same tape on a Sun 4/370 without any problems. Anybody having had similar problems /advice? Thanx, Tatjana
