Greetings. Not to spoil the good fun on the board but I have
a small problem. It seems that Linux isn't too happy with my
Maxtor 212A. Let me first give the errors, then the steps taken
to solve them, and, last, why it's weird:
1) Mounted my C: [eek!] on /msdos with "mount /dev/hda2 /msdos
-t msdos" (/dev/hda2 is 100MB)
2) trying to cp a 770,801 byte files from /msdos/tmp to /tmp
(/tmp is a 10MB partition) gives the following errors:
"HD: read_intr: status = 0x59
HD: read_intr: error = 0x10
.... (above 2 lines * 10 or so)
HD-controller reset
HD: read_intr: status = 0x59
HD: read_intr: error = 0x10
.... (above 2 lines * 10 or so)
harddisk I/O error
dev 0301, sector 199,740
cp: test.big: I/O error"
3) If I check the size of the portion that was copied BEFORE
the technicolor yawn, it's around 540K 8 out of 10 times.
Now for the steps taken: (I have the "standard" (minix) SLS fs)
1) From Linux: fsck -av /dev/* (all 3 partitions!) All perfect!
2) From MS-DOG: Notron NDD on /dev/hda2... All perfect!
3) From MS-DOG: PcTools DISKFIX on /dev/hda2... All perfect!
4) From MS-DOG: CHKDSK... All perfect!
5) From MS-DOG: "copy test.big test_big.big" ... All perfect!
6) Lesse... that's about all one CAN try...
What's weird:
1) MS-DOG programs verify all to be fine
2) I can copy the file in MS-DOG to a different directory, etc.
3) If I copy the file from one directory to another and then try
to access it from Linux I have a 30% (calculated :-) better chance
of getting it copied to Linux's /tmp... real weird.
4) 1 out of 10 times it copies just fine!
5) in the 30-40 times I tried the copy, I got logged out twice
with a core dump... (that is, I got logged out after the errors
above and when I logged in, there was a 100K core)
6) I've been running Linux since the early .90's - lightly,
97.1 & 98.5 heavily - NEVER had a problem! (Linux=wow!)
7) It only happens on SOME big files - magic size? I can copy
2MB files just fine!! What's so special with 770,801????
8) Sorry to make this so long...
No big problem... I'm getting a SCSI card for the Toshiba
XM-2100A CD-ROM (anyone know if it works with Linux??) that
I got for $25 and fixed ;-) and a new HD... MS-DOG will get
this one back (and from the looks of it, it can have it ;-)
Take care.
