Post by Ian RobertsHi
A friend of mine had trouble reading some of her zip 100 discs.
I tried them out on my PC with an external SCSI zip 100. All that happens is
we hear continuous clicking. Some of them come up with a message that the
disc isnt formatted and do I want to format it. All her other discs
read/write OK.
I've never had this problem with my own discs or other peoples discs before.
Welcome to Click Death... Head to http://www.grc.com and look for
the section on Zip & Jaz drives.
Post by Ian RobertsCan this disc problem be rectified?
As it is, no. If it's the only disc having a problem and it's
already failed in 2 different drives consider the disk, and any data
it contained, hosed. The only practical option, if you really REALLY
need the data is a professional recovery service. To attempt to save
the disk the only thing you can do is a long format and see if the
format completes.
If this is happening on more than one disk, and you can still access
some of the other problem disks, what does the Iomega software
report for the Disk Life and Format Life? (Right click on the Iomega
drive icon.) If the "Lives" are low the spare sector pool could be
depleted and the repeated clicking is a last ditch attempt to
retract & clean the heads and attempt to write to the disk again.
Post by Ian RobertsMost of the discs are very new and had
little use. Would Iomega replace them under waranty?
Yes. But only the failed disks.
Post by Ian RobertsCould this error be created by a problem with her USB 100 drive?
Not if this is the only disk she is having a problem with. But if
this came on rather suddenly, and it's happening on several disks,
the drive itself could be failing and trashing the disks in the
process. grc.com has a freeware program - TIP.EXE to check disk and
drive problems. Offhand I can't recall if it works with USB drives
though. It definitely works with SCSI, parallel and ATAPI IDE
drives.
NB: If this is a physical failure of the drive, and it's causing
surface damage to the disks, you risk trashing any other Zip drive
as well that the "clicked on" disks are put into. There's no easy
way to tell, short of one of the heads falling off (that actually
happens), if the drive is causing physical damage to disks. In most
cases it isn't so extreme that the damage can be spotted with the
naked eye. But for openers scan the edge of the clicked on disks
through the metal slider, looking for rough edges or tears in the
media. The point being, until the problem is sorted out be very wary
putting the problematic disks in other drives.
