I get this kind of warning also, though the number of unreadable sectors
I get is in the single digits. All disks have some unreadable sectors.
It's just a product of the manufacturing process. A low-level format
discovers these and marks and maps them so that they aren't used... so
not a big deal. (You are, after all, getting the message about them,
right?) So having unusable sectors isn't in itself a problem. You've
got a lot of them, but then perhaps your drive and the part of it you're
using is much larger than mine. If this 993 sectors is a considerable
percentage of your disk, then you'd have cause to ask for a refund or
exchange on the purchase, but still no real cause for alarm. However,
if that number of sectors increases over time, then you have a sign of a
failing drive and obviously would want to replace it ASAP.
