  1. Hi: sorry for the delay. here is the update: The Bad Blocks were unmarked after I erased the drive with HDDScan. Now this drive seems ok. The other drive, the one with many "greens", remains the same, now about 60 greens. I will wait a couple of weeks, and scan again, to see if the number of greens rise again.
  2. okay, understood. Anyway, before running ESTOOL>erase I will try to erase these sectors with HDDScan (this way they won't be reallocated yet). Now I am still doing the full scan to see if there are more bads. Something I don't understand, is why this disk didn't develop Bad Sectors when it was formatted first time (long format, writing to disk), but developed 6 bad sectors when I filled it with data.
  3. sorry for the delay: I have formatted the drive using Windows. Long format. But nothing has changed. In SMART, the sectors are still marked as Bad, but only pending, and in HDDScan they show up when I do a partial scan around the affected area. Proceeding to full scan.
  4. @666: Ok, thanks for the detailed explanation about bad sectors. I will format this drive, and see if the pending bads have been unmarked. But first I will ground the drive. @weaker: yes, 666 suggested that my disk's shrinkage to 32MB was caused by Gigabyte Ghosting function, but I agree with you, I think the cause was the Bios backup function. I think the Gigabyte Ghosting function doesn't reserve any space in disk unless you invoke this function... but I have no confirmation of this, because I haven't tested it.
  5. I think these 6 Bad sectors are not bad sectors really. Is there any way to free them up? I have been googling, and nothing conclusive, but it seems that you can "unmark the bad blocks" and get them back for use, by simply deleting the MBR, or repartitioning the drive. Is that ok? well, maybe just erasing them, will do the trick, as they are still "pending", and "not yet reallocated"...
  6. Hey, I know it sounds ridiculous, but could it be that my bad sectors happened because my drive is mounted on a plastic adaptor, without electric contact with the chassis? The bad sectors appeared when I did the massive writing on the disk. Look at this: http://users.iafrica.com/c/cq/cquirke/baddata.htm I don't understand well what it says, but could be related.
  7. okay, I see that md5 redundancy can solve many other situations when a file is broken. I was referring to bad sectors. Apparently Windows can detect that a file is broken when the cause is a bad sector. without having any other redundancy. I am going to explain the precise sequence of what happened to my F1 (1TB) drives. Drive 1: Purchased in July. Initially good scans. Drive 2: Purchased in August. Initially horrible scans, lots of greens, but no bad blocks. Lots of tests but no writting on the disks... ... Now, first I filled Drive 2 with data. Scan improved. and no bad blocks. Then I copied Drive 2 contents into Drive 1 (just Copy in Windows). And then, I run MHDD, and BadBlock appears in Drive 1. I have just checked SMART in this drive 1: it says: "6 pending sectors". No less than 6 sectors! They are still not reallocated. Just pending for reallocation. If I erase them with ESTOOL, I think it will map them out, and the drive will be "ok" again.
  8. md5? but in theory there is no need for that. The normal filesystem already has built in redundancy to detect errors, no? in fact, HDDScan and MHDD detect Bad Sectors without the need of md5 or any other extra redundancy. Just that they don't tell you what files are affected. Isn't there any program capable of verifying the files, using this built-in redundancy? --- Is there any way to disable Gigabyte's Virtual DualBIOS backup? After what has happened, I don't feel safe with it. I would gladly disable it. But I don't see anything about it on BIOS or in the manual. ----- re. the bad sectors that I got, I don't know if should erase the disk to force reallocation, because once reallocated, the ESTOOL will pass without error, and thus, the shop wouldn't want to RMA... this is all very annoying grrr.
  9. Well, I don't know, I did read the SMART report several times when I ran HDDScan, and there was no pending allocation. Everything was ok. I saved these reports, and I have them with me. The bad sector appeared suddenly after I filled the drive with data, and I ran MHDD. This was the first time I wrote data on this drive. Until then, it was only formatted Yes, I powered this drive at the same time with the other one. In fact, after I filled the other one with data, I copied that data to this one. I have ran Samsung's ESTOOL, and indeed it detects the problem: it reports 6 consecutive bad LBAs. It prompts me to ERASE the drive, and in case the error persists, contact Samsung. So, isn't a bad block enough to return the drive? This one is less than 2 months old!!
  10. Surprise: I got a bad sector in my good 1TB drive!! Until now, the drive was empty, and formatted, and scans were good. But today, I have filled the drive with data, and now a Bad sector appears!! The scan is good (8 greens) but now there is a bad block. The bad block appears in both MHDD and HDDScan!! How is this possible?? I did nothing out of the ordinary on this drive. It was in the other one, where I did all the experiments. On the other side, I have also filled the bad 1TB drive with data, and the scan has improved a lot. Now only 49 greens in MHDD. And no bads.
  11. @both: I think: Xpress BIOS Rescue=Vitual BIOS Xpress Recovery=Ghost No, I didn't install nor run any of these. @666: Is the MBR restored automatically when you Init, partition, and Format the drive with Windows?
  12. and does it work with modern hard drives??
  13. ok, as I don't have linux, I will do fine with the russians. I trust them I am using a software called MyTheatre, for satellite TV. This is a russian program too, and it is great. ProgDVB is also russian. Don't underestimate russian programmers, baby. I don't know anything about FTP servers, but I understand what you say about the benefits of open-source code.
  14. guys, after my disk was shrinked to 32MB, I went to Samsung ESTOOL, and out of desperation, I erased the MBR. Is this important? Is there any distinct info in the MBR that can't be restored? The drive is working ok now, doesn't look like there is any problem with that.
