First off, I apologize for the lengthy post. Now then...
I have a couple of internal scsi zip 100 drives. One of these is one the
original blue internal drives and the other was more recently purchased (Jan
2000). Both drives have worked nearly flawlessly until the other day when
the newer drive started acting up. Note that both computers are running
win95 osr2.1. The old drive is connected via iomega's isa scsi adapter
(adaptec 1502 I believe) while the newer drive is connected to an adaptec
2940u2w.
I initially noticed that files saved to the drive would not exist once the
disk was removed and reinserted. This behavior began after using the disk
with a zip 250 drive on a different computer. I had no previous problems
with this particular disk. The disk could be read in my older zip 100 scsi
drive but the files did not show up there either. I could write files to
the disk with the older drive and then read them with the newer drive but
any files written with the newer drive would not show up.
I then ran TIP on the disk using the older drive. It found some 1500 soft
errors and a couple of firm errors which it relocated to the spare sectors.
I was going to reformat the disk thinking that the brief usage with the zip
250 drive may have messed up the format. However, before formatting I tried
to use PGP'S file wipe utility to remove the files written by the older
drive. The operation appeared to be successful until I removed the disk and
reinserted it; the files were still there. Note that pressing F5 to refresh
windows explorer did not make any noticeable difference.
I was about to reformat the disk, but when I reinserted it the drive started
clicking. I ejected the disk and checked the edge which looked ok but it
still clicked when I put it back in the drive. I checked another disk which
had some redundant data on it and that one clicked as well. I reproducibly
get two clicks and windows does not detect a disk in the drive. However,
the disk can be read in the older drive so I know it's ok. I have not
rechecked the original problem disk in the older drive.
It seems like the newer drive has been hit by click of death, so I took the
cover off the drive and checked the read/write heads. They appear to be
ok. I tried lubing the guide wires as described by Gary Brand (I can post
the original text if anyone's interested) and discussed by Steve Gibson.
Note that this didn't help but I was unable to get the heads to slide freely
in and out as Gary describes and was a bit apprehensive about forcing them
as I didn't want to damage the drive any further.
Is this drive repairable? Or, should I try to return it to iomega? Are
they still accepting returns on out of warranty clicking drives?
Any suggestions would be greatly appreciated.
Thanks, Eric
