External Hard Drive Question
Michael Fogler
my iMac with Snow Leopard. This is my Time Machine backup.
Everything went fine for a few months.
One day, it said that the backup couldn't be done because the disk
appeared to be read only. (It had been written to every hour for months
prior to that.) I launched Disk Utility and had it Verify the disk.
After that long process, Disk Utility said that the disk appeared to be
okay. Then it did the backup just fine, and continued to do it hourly
for a few more weeks.
Then today, the whole thing happened again (you can start reading above
at "One day, it said..." Disk Utility again verified the disk (after I
got the message that it appeared to be read only) and found no problems,
after which a backup occurred as it normally does.
Any ideas about what's going on here?
thanks.

It might be that your drive is about to die. I've had two WD MyBook external
drives die on me in the last few months, and a third one is currently
disconnected until I can get a replacement drive 'cause it's started to emit
the Click of Death and I want it to live long enough for me to back
everything on it up.
In all three cases the WD drives had one year warranties and started to give
trouble about 15 months of service.
I will not be buying WD drives in the foreseeable future.

Isn't there 3 or 5 years of manufacturer's warranty on the harddisk
itself? - At least you can check it here...

It might be worth having a look...

I have heard that Seagates are more reliable and have been going with
them for the last couple of years w/o problem. Had a lot of problems
with LaCie. Not sure where they get their drives.

Seagate's drive quality has plummeted these past few years, as have that of
other manufacturers.
LaCie gets its drive mechanisms from Seagate, Samsung...etc. The same
product may be built using a Seagate platter for, say, six months, then the
next batch may have a Hitachi mechanism, and the next another mechanism.
Etc.

I have never had any problems with neither WD nor Seagate, so that's the
two brands I always use... - If I remember right most of the LaCie
drives (still) are using IBM/Hitachi harddisks in their enclosures -
both 2,5" and 3,5". - And when it comes to harddisks I donot trust the
Hitachi 3,5" units - only the 2,5" TravelStar models...

Most of the LaCie problems have been with their power supplies. In
extreme cases, defective power supplies can kill any hard drive through
intermittent supply of power or surges.
I, nor ANY of my clients, have EVER had a problem with Hitachi hard
drives of any size or description. (This does NOT apply to IBM hard
drives BEFORE Hitachi bought the business from IBM.) While ANY hard
drive manufacturer can have problems, Hitachi seems to have avoided them
for the last 5 years or so.
I too have heard numerous stories of Seagate failure. The notorious
firmware glitch in a couple of their larger drives when first introduced
is well known. Search Macintouch's hard drive forum for details if
you're interested.
Another way to reduce your risk with HD purchase is to buy
'server-grade' drives, which have a 5-yr warranty. They cost more, but
usually do last longer.
Here are 2 Hitachis for comparison:
