Hi,
I have a manufacturer-installed CDC (Control Data Corp.)
28-millisecond 40 Meg hard drive in my Epson Equity II+. The drive is
partitioned into 32 Meg for C: and 8 Meg for D:. Well, yesterday, I
found a problem with my disk:
I. I ran PC Tools (ver. 1.1) mapping option on C drive and
everything was O.K. but when I tried it on D drive, it showed 2
bad sectors.
II. I used the CHKDSK command in Dos and it showed me that there
bad sectors in BOTH C drive AND D drive.
III. I then used ver. 3.0 of PC Tools - mapping of the C drive
showed a perfect drive, but D drive could not be read, due to a
"Bad Fat Sector."
I only got this machine last week, so these bad sectors must have
been there when I got the machine. Most probably, if I bring it back
to the dealer, he would just order a brand new drive, which would
probably take weeks. I have the following questions:
1. Why is there a conflict between what CHKDSK said and what PC
Tools said?
2. Is it normal for the hard drive to have one or two bad sectors?
3. What's the difference between a low-level format and a regular format?
And would a format purge the hard drive of its bad sectors?
4. Or better yet, should I just go back to the dealer to ask him
for a new one or repair the existing one?
I would appreciate any answers or advice concerning the matter.
Thanks a lot,
Patrick
