Fredledingue Posted December 22, 2007 Share Posted December 22, 2007 (edited) "D" is my second hard drive which has problem recently exposed.When DMA is enabled on this drive, the computer freezes sometimes, when I try to access files on it.Running scandisk under Windows froze the machine as well.Running scandisk under DOS showed "Scandisk encountered a data error while reading FAT on Drive D. This prevents ScanDisk from fixing this drive. [Exit]"Then I disabled DMA, and scandisk seemed to work under Windows.It took about one hour to scan the first 70,000 clusters, then 2 hours to do 500,000 clusters, out of 1,200,000.I stopped the process at about half the cluster scan because it was too late in the evening. I will re run the check tomorrow fully.Here is the ScanDisk.log:*******************Microsoft ScanDisk for WindowsNOTE: If you use an MS-DOS program to view this file, some of the charactersmay appear incorrectly. Use a Windows program such as Notepad instead.Log file generated at 20.12 on 12/22/2007.ScanDisk used the following options: Thorough test Check dates and times Automatically fix errorsDrive (D:) contained the following errors:ScanDisk could no longer write to or read from sector 1376 of this drive's file allocation table.

I still didn't try to read files on this drive by fear of crashing my PC.Thanks for your help. Edited December 22, 2007 by Fredledingue Link to comment Share on other sites More sharing options...
Kelsenellenelvian Posted December 22, 2007 Share Posted December 22, 2007 UNPLUG IT!! Don't use it untill you get a new drive to put the info on it..... Link to comment Share on other sites More sharing options...
PassingBy Posted December 22, 2007 Share Posted December 22, 2007 Hmmm .....Sounds like surface degradation or mechanical defect(s) to me ... Probably more prudent to not run another scandisk at this point. If the scan stutters all over the drive surface, it is possible that the read/write section (maybe amplifier/coil/etc etc) is wearing out.IMHO, you should attempt to copy your most important documents first before running a scandisk again. If the previous scandisk has gone through the first 10%-20% of your drive, it "probably" has fixed the FAT and DIR (YMMV). After having copied those wanted documents then you can attempt to scan the drive again. If the drive is a slim maxtor, its going to RIP soon. If its a seagate, data recovery is possible but will burn a big hole. If its a WD, a surface erase can be of some help. If its a Samsung, its odd coz they're tough.

Sysdll Posted December 22, 2007 Share Posted December 22, 2007 Yes first back up your important data and get another drive. I have drives that have shown similar scandisk logs after power outages. I’ve had some success in making them useful again by using the manufactures original startup utility and then Scandisk from the Windows ME boot disk followed by a format from whatever OS startup disk you’re using. All previous information is lost this way but it’s worth a try before tossing the drive. Link to comment Share on other sites More sharing options...
Fredledingue Posted December 23, 2007 Author Share Posted December 23, 2007 (edited) Thanks to all, for your replies.SysdllI'v got a power outage recently, yet it was still working properly after that. The file allocation table could have been affected, I don't know.Do you think that repeated power outages could physicaly damage the drive? Or it's just bad for the datas?The irony is that I'v bought a power accumulator (Mustek) supposed to provide power for computers during outages: It works when you pull the plug out of the wall, it doesn't when the power shut down from the network. Money in the wind...Anyway...This drive is already over 5 years old. I won't mind buying a new one.Going to disconnect it now.

RJARRRPCGP Posted December 23, 2007 Share Posted December 23, 2007 If the drive is a slim maxtor, its going to RIP soon.I agree. They often start with inconsistent sector access. Link to comment Share on other sites More sharing options...
herbalist Posted December 23, 2007 Share Posted December 23, 2007 The last time I saw error messages like that from Scandisk, the drive was on its last legs. The problem came on with very little warning. By the time I realized I had a problem, I'd already lost data. Managed to recover about 80% of the data by installing the drive as a slave and copying data a few folders at a time. Have you tried Spinrite? I haven't used it but it's reputed to be good for data recovery and fixing errors.Rick Link to comment Share on other sites More sharing options...
Fredledingue Posted December 24, 2007 Author Share Posted December 24, 2007 Thank you for all your compassion for the dying hardware, especialy on this christmas eve. I have copied about 9 Gb of the most useful datas to the other drive with one error here and there. About 99% of the datas have been saved out.TotalCopy (aka Tcopy) has been of great help copiying the datas bypassing the errors without a crash.Then I disabled the drive from bios. I'll disconnect it as soon as I figure out which one it is in the case. I suppose the one that is cold is the one to remove but the fan and the fresh air blowing to them is so efficient that there is no feelable difference of temperature.Is it bad for hardware to be maintained too cold?

noguru Posted December 25, 2007 Share Posted December 25, 2007 Unless you are a Eskimo and live in a iglo, no. My WD is supposed to operate between 5°C and 55°C according to their own specs. Don't worry about that. It's not abnormal that a five year old drive gives up. Especially when used a lot. Sometimes it's starts with degrading performance and you can wait (and backup!) for the end to come. Just one power outage can be to much for a old drive.

Fredledingue Posted December 25, 2007 Author Share Posted December 25, 2007 Thanks, noguru!My computer is in the cellar staircase, it's cold there but not under 0°C, and surely not under 5°C neither.It's also a WD. Link to comment Share on other sites More sharing options...
DonDamm Posted December 25, 2007 Share Posted December 25, 2007 Cold is generally good. If you value your data, then always make a back up before it crashes. The quickest way to do this for future reference is to make an image of the entire disk and save that somewhere else. Then you can always retrieve data if you really need it.A power outage can indeed play havoc with the disk corruption and even the electrical control board on the drive itself. That may not be the case here, but you can't be sure without testing, so save your data first, then repair. Spin Rite is excellent for for a disk in your situation and wilol identify any bad sectors. It is like Scan Disk on steriods. It is slow, though, so set it to go overnight. If you can read data, then your partition table is probably okay. What happens to older disks is that the magnetic domains in some areas become a bit weaker and when the signals are right near the borderline, it becomes difficult for the drive to distinguish between a 1 or a 0. Those signals generate scan errors and the bad sectors are usually marked and avoided. As a disk ages, more and more of those can show up. ScanDisk and other utilities will mark these and then activate replacement sectors from an unused part of the disk. Most of this is transparent to the user until the errors become too numerous and the "spare" sectors too few.Also, if the FAT is corrupted just a little, some of the file bits may have become lost or crosslinked. ScanDisk will find these and collect them into one file. Usually it is useless. If it's a five year-old disk I'm guessing it is no more than maybe 40GB. A brand spanking new 500GB Samsung will cost you no more than about US$80-90. I'd spring for a new disk and relegate this one to temp duty and not for important data.Good luck with it!

Fredledingue Posted December 26, 2007 Author Share Posted December 26, 2007 Thanks DonDam,There were indeed "crosslinked" files during previous scamdisk checks.As soon as the store reopen, I'll get a new HD. It will be cool to have an extra 250Bg or something... and cope with the 138Gb limit. Link to comment Share on other sites More sharing options...
RainyShadow Posted December 27, 2007 Share Posted December 27, 2007 Could you post the SMARTUDM report for this drive? There is a small possibility that the fault is in the cabling or the controller, not the drive. Already happened to me in the past.Aside from this, try not to use the drive until you are ready to copy all data from it. Link to comment Share on other sites More sharing options...

PassingBy Posted December 29, 2007 Share Posted December 29, 2007 Hmmm .....Seagate Barracuda IV ST340016A with 40GB capacity. The smart readings looks okay to me but as per your earlier description it does seems to have some difficulties with reading/writing. The reallocated numbers are small. There's a way to find out ...Once you have copied out your data. Use any suitable utility to zero fill the entire drive then scan the drive again. If it seems to be smooth while scanning without much stuttering then its propably safe for normal use else its prudent to use it for secondary backup.Rgds Link to comment Share on other sites More sharing options...
