Hi.
I'm having problems with writes hanging my hard disk and I
was wondering if anyone has heard of something like this.
My system is a Mac+ (upgraded twice from a 128K mac) and I
just installed a 380MB external hard disk (320MB formatted). The
disk is an HP 97536SP Rev 8834. I cut the reset line (pin 40 on
the SCSI cable) because of a Unit Attention problem I asked about
on this list a while back. The system boots fine from this disk.
I have a vanilla (just installed) version of system 6.0.5
and my driver is SilverLining 5.25 with the SilverLining fast
handshake loops installed. No other inits installed yet.
I have partitioned my drive into a number of partitions.
All the HFS partitions except for 2 are exactly 32767K. My boot
partition is 8192K and the final partition is whatever was left
over. All filesystems are sized exactly as the partition size.
I automount/mount only 5 of these partitions.
Here is the problem. When doing a finder copy, either from
one partition to another or from a floppy to one of the partitions,
the copy hangs on the "writing <blah>" part of the copy. The
interesting part about this is it appears to happen right in the
vicinity of a total allocation of 2 MB on the destination disk. I
assume this based on the total allocation on the partition before
starting the copy, the size of the file(s) being copied, and the
status of the progress bar in the finder dialog when the hang
occurs. For example, I have an inital 1,400K in disk, I'm copying a
775K file, and the copy hangs on write when the progress bar
indicates about 3/4 done.
When the hang occurs, SilverLining access light (the little
dot in the upper left corner of the screen) is on and the access
light on the hard disk is on. The watch cursor is not spinning but
the cursor follows mouse motion normally. Of course, I can't do
anything with the system other than move the mouse around.
I know this problem isn't related to a specific file OR a
specific partition, I've done enough testing to verify that. I ran
SilverLining's non-destructive bad sector tests on the entire disk
overnight with no errors reported (a total of 3 1/4 passes).
Because I've cut the reset line, I have to power cycle the
drive to clear it and I don't really want to do this too much; I've
heard that that's one sure way of quickly destroying a drive.
Does anyone have any information, suggestions, or advice. I
am going to call LaCie later today to see what they have to say, but
it's not even 7AM out there yet.
