While I was working on my pc yesterday it suddenly begin to behave
too much sluggishly so I restared my comp but found that it showed
disk read error occured - press ctrl+alt+del to restart & I was unable
to boot into windows. So I restarted & the same error occured again.
So I decided to find out the problem.

I booted my comp with bart pe boot CD & tried to recover data from the
80GB seagate sata hdd ( bought last year from vedant computers)
to my pen drive.. When I was going to access the E drive which has nearly
20GB of data it showed completly empty :( I recovered some data from F driv
& suddenly CRC error occured & I was unable to recover rest data. So I
thinked why not try the chkdsk. I issued chkdsk command with
chkdsk /f /r flag but the comp hanged.

Then I tried to Install XP by deleting all of the partions from 80GB hdd.
I deleted all partions & created a 15GB fresh partion & the rest space unpartioned.
A full format of C drive took around 20 minutes :shocked: When the format was complete
xp took around 40 minutes to install where it usually takes only 20-22 mins. Also
Xp's boot up time is around 2-3 mins now on fresh install :shocked:

After xp was installed I installed HDTune & check the 80GB hdd for bad sectors.
It showed some bad sectors. I am mentioning the test result in here :

( As if the bad sectors will not show up I will not get replacement I doubt )

Don't worry dude, even my 250 HDD developed bad sectors. I sent it to Seagate and got a 500GB HDD fro replacement!!! They replace it with the higher model if they do not have your model's stock with them.
To check if its surely developed Bad Sectors download Seatools from Seagate.com and run a short drive self test, it'll take about 10mins , if it FAILS then here's what to do :-

Seagate HDDs have a 5 year warranty. You can get yours replaced by sending it to Seagate. For that visit Seagate India and get a Replacement Request by entering your HDD's serial and Model number online. They'll give you the address to ship it to (Chennai) and how to pack your drive. Be sure to pack it correctly in anti-static bag! And you'll get a brand new drive in 15Days
You'll be a hapy man!


Legen-wait for it-dary!
^^ really? I have a seagate 250GB too!!! and I want a 500GB :D I'll run the tool and see... Considering I live in Chennai, I can probably finish this fast :D


is there anyway to repair bad sectors? my samsung portable HDD got 92kb of bad sectors today...although in warranty, i dont think i will be able to get it replaced or anything cos this one my uncle got for me from Israel.


Legen-wait for it-dary!
^^ No, bad sectors are caused on the surface of the drive itself, so they cannot be repaired. Try asking your samsung dealer nearby, or call up the samsung hotline, if any. You still have the warrantee card, bill etc, right? You can try showing them as proof.

Every Hard Disk has a couple of KB extra sectors, so if a few KB develop bad sectors the Partition Table can be rewritten to ignore those bad sectors and use the extra sectors instead by using the manufacturer's repair utility but if they are of order of MB's then its better to get it replaced.

Seagate is a reliable company, even if a hard disk does develop bad sectors they are replaced promptly, you just need its model number and serial number to make a RMA request online. Even though i had a hard time backing up all my data before sending it for replacement but after 10 Days i got a 500GB one instead of my 250GB, i felt on cloud nine. Such thins don't quite happen that often do they?



At Hell's Disq
^^^ but they aint that rare too.have seen 3 guys get 500GB as replacement for 250& 320GB hdds.

such a thing doesnt happen with WD though.

My hdd has around 8 or 9 Mbs bad sectors but :

Yesterday I wiped & cleaned my Hdd with R wipe & clean, Formated all 4 partions
on the 80GB hdd & performed chkdsk. But windows doesn't showed any bad sectors.
Then I run HDtune & it found bad sectors again.
Then I run Seatools & it found errors & suggested me to fix those errors but
I skipped.

Now my question is :

Should I fix those errors with seatools ?

I think if I gave the hdd to service center they will repair those bad sectors using
seatools & will not give me a new hdd as replacement ?

Guys what do you suggest ?


Self Confessed Geek
Repair will only try to recover data from the bad sectors if they have been written over, and that is it.
In order to know if your drive will be replaced, download and install Seatools and run a "Short Drive Self Test". If it shows FAIL then send your drive for replacement buddy.

Seatools error fix log ( created by me ) :

I started the long test

at around 4% it found 97 errors & suggested me to repair
those errors so I did so.

Again I started the long test :

at around 37% it found 100 errors & suggested me to repair
those errors so I did so.

Again I started the long test :

at around 73% it found 87 errors & suggested me to repair
those errors so I did so.

Again I started the long test :

at around 71% it found 88 errors & suggested me to repair
those errors but these time I lost my all patience :mad

What you guys suggest ? Should I try once more coz on the seatools
readme I found :
When SeaTools discovers a bad sector through reading, at the end of
the scan it displays a list of the bad sectors.

If a sector is in use, then that file is incomplete or corrupt. When
a bad sector happens to align with a folder or directory listing
structure, then the links to files and sub-folders it manages may be
broken. Sectors are often not in use.

You should carefully consider the importance of your data. While the
sector is currently unreadable, if the file or folder is important to
you then you may need professional recovery services to possibly
reclaim the data. In this case, select NO to exit without trying to
reallocate blank replacement sectors on the drive.

If you have decided that the file or folder is replaceable, already
backed up or just not important to you, then you can tell SeaTools to
attempt to overwrite the sector.

By design, modern disc drives maintain spare sectors for reallocation
purposes. Usually, sectors become difficult to read long before they
become impossible to read. In this situation the actual data bytes in
the sector are preserved and transferred to the new spare during a
sector reallocation. Similarly, when a disc drive writes data and
encounters a problem, the drive firmware retires the problem sector
and activates a replacement before giving successful write status.

If you give permission to overwrite a bad sector SeaTools will attempt
to write a pattern of zeros to that sector. Usually, this action will
assist the disc drive firmware in managing the problem by retiring the
problem LBA and activating a spare in its place.

or you guys think I should take it to the service center or to the
shop from where I had bought it. I am a little panic abt the
online RMA coz on the PACKAGING terms of the hdd they said :


3. Enclose the drive in an anti-static container. If packaging more
than one drive, use a separate bag for each drive.

4. Secure the drive in Seagate approved packaging. Use 2-inch thick
foam rubber in a corrugated box. Multiple drives in a single box
should be packaged with foam rubber between each drive. Do NOT
use foam packing pellets, bubble wrap, or newspaper. (See Seagate
Approved Packaging section, below.)

What is Seagate Approved Packaging?

We recommend you ship your drive in its original box and packing
materials, which you should always keep for storing and shipping
purposes. If you do not have your original packaging materials,
use 2-inch thick foam rubber in a corrugated box. Multiple drives
in a single box should be packaged with foam rubber between each
drive. Do NOT use foam packing pellets, bubble wrap, or newspaper.

Now in point No. 3 & 4 they'.re telling us to pck the drive in the original
anti static bag with foam.

on the other hand in the approved packaging section they're telling us
either we should only pack it into the original antistatic bag or if we
don't have the pack then we should pack it into some 2 inch thick foam.

Now guys can one of you tell me the exact procedure of packaging the hdd
& where I can get those 2 inch thick foam ?

Also which courier & what kind of sending method I should use ?
What will be the charges of sending the Hdd ?

Guys please help me out....I'm loosing it big time.....
