4 weeks ago , bought a 2.5" 640gb hard drive from PB tech for my windows 7 laptop.
Formatted as ntfs, all was OK for a couple of days, then, suddenly couldn't read some files/folders.
Ran chkdsk, took a long time (~10 hours) to run, reported 6 files with bad sectors, 13 clusters added to bad clusters file, and correct errors in volume bitmap.
Hoping it was a one off, I continued using the drive.
Several days ago, similar problem but more files could not be read, and opening some folders windows reported a corrupted folder message.
Ran chkdsk, that took nearly 24 hours to run, reported similar errors as before, and also corrected errors in the MFT DATA attribute (whatever that is).
I did not trust this drive anymore.
Returned to PB tech, they ran HD Tune check, which took about 2 minutes to run. HD Tune reported no errors so PB Tech said there is nothing wrong with the drive and I should continue to use it.
I told them chkdsk reported all of these errors, and they said chkdsk was crap and HD tune was much more accurate and used by the drive manufacturers to verify drives.
I asked the service tech to open the corrupted folder, and as expected windows showed the corrupted folder message. He told me that it was just a 'software' problem and he could fix it. I said OK, and he proceeded to reformat the drive, then said it was fixed .
I told them this was a ridiculous fix and asked for a new drive.
They said if I wanted a new drive, they would have to send the drive overseas, and wait for the manufacturer to diagnose and fix the problem. But, in the meantime I would not be able to use my laptop and they would not provide a replacement drive for this time either.
Finally, a line of customers formed behind me, and after an hour of arguing they gave up and just gave me a drive, threatening me that if the replacement drive failed they would not replace it.
I was absolutely amazed by their attitude. Computer Lounge (whom I often deal with) would just replace the drive immediately.
But surely, reformatting the hard drive is not an adequate fix? Especially with the errors chkdsk had reported (although, they did not care about this as they believed chkdsk does not work).
