Chkdsk says it's a RAW drive!
The message said, roughly.
You have a RAW drive. Chkdsk will not work with a RAW drive. This used to be a FAT32 drive that ran winME, and chkdsk used to work on it. Wha' happened? Can a HDD go bad just sitting around, like batteries do? Details: I haven't used my IBM Thinkpad 600E for a couple years. For the last 3 months I've been searching for the power cord, which should have been on the floor right next to the computer. Impatient, I took the drive out of the computer, verrry easy to do, and connected it via a Rosewill RCW618 SATA/IDE adapter cable, and the directory structure was there, and some files, and I could copy them, but many files seemed not to be there, or couldn't be read. I tried .jpg files especially because it's easy to tell if they "work". Some appeared quickly, others seemed not to appear at all, and one showed up after minutes I think, after first only the top quarter of the picture showed, and I had gone to an entirely different program for ten minutes, and came back to find the picture fully displayed. But eventually the "F: drive" dropped off the list of drives in Windows Explorer!! I could unplug it and plug it back in, but this time it came and went faster. So I tried other hardware, a 2 1/2 inch enclosure that I'd never used before. Again I could see the directory structure, and lists of files with their lengths, etc. but many were missing. So even now the drive works a little but chkdsk says it's a RAW drive. Any suggestions as to how to get my data off. Thanks a lot. FTR, I already copied 3 years ago all the .jpg files to another computer which is backed up. All I really would like is the email t that I sent and got on a trip I took, since I plan to got there again, and really only a couple addresses, which I can eventually replace, but maybe there are things I've forgotten. |

Can a HDD go bad just sitting around, like batteries do? Yes. The surface magnetization weakens over time. Electrolyte capacitors go bad. Lubrication fluid may leak or go bad. HDDs are unsuitable as a long-term storage or archival medium. Details: I haven't used my IBM Thinkpad 600E for a couple years.

All I really would like is the email t that I sent and got on a trip I took, since I plan to got there again, and really only a couple addresses, which I can eventually replace, but maybe there are things I've forgotten. Ordinarily, I would suggest professional data recovery from a reputable (!) outfit. (Lots of fraudulent and incompetent ones out there...). In this case, locate the specific files, and try to copy them a dozend times or so. If that does not work, then professional data recovery is the only chance and it is a slim or really expensive ( 1000 EUR/USD) one. But quite frankly, your chances are slim. Better prepare to deal with not getting this data and think about what to do differently next time. Arno -- Arno Wagner, Dr. sc. techn., Dipl.

Try freezing the drive. Maybe after the freezer I can even put it in a little cooler or a couple layers of thick paper bag with some blue-ice or something that will keep it cool longer. (wrapped to keep condensation away from the drive.) OTOH, I've narrowed it down to only 2 or 3 files I really want, which should go quickly. I'll try this tomorrow. Thanks a lot. FTR 've narrowed it down to two basic files that I really want, the Outbox and the Address book. And I've found a few of the addresses in the inbox, when they wrote back to me. I found everything from the Inbox on my regular desktop computer, because I didn't delete anyting from the server when using the laptop, so it would all go to my desktop too when I got home. Next time, from now on whenever I use a laptop, I'll send a copy to myself of everything I send. |

I'm glad Rod reminded me. 2) In the opposite direction, late last night doing general file maintenance, I came across an xxcopy log file for this very computer, where I copied 4 gigs to the F: drive.

Not hitting the nut but squeezing it against the table. The nut went flying across the room and I never found it. The computer worked fine until I tried to restart it. Then I had to run chkdsk for 60 hours, about 5 or 10 minutes for each error it found, until it worked again. Something like 500 bad sectors out of a million. (The numbers don't add up but I've forgotten the details of this too.) After that, I used the computer for about 30 hours over 3 months and everything worked fine. Then I stopped using it until I couldnt' find the cord and took the harddrive out this week. I don't know if the earler crash I created was responsible for the failure this week or not. Thanks all |

On Tue, 04 Jan 2011 15:27:41 -0500, mm put
finger to keyboard and composed: The message said, roughly. You have a RAW drive. Chkdsk will not work with a RAW drive. This used to be a FAT32 drive that ran winME, and chkdsk used to work on it. Wha' happened? You need to clone your drive ASAP, sector by sector, and then use data recovery software on your clone, if necessary. Some freeware cloning tools are ... HDclone: http://www.miray.de/products/sat.hdclone.html dd_rescue: http://www.garloff.de/kurt/linux/ddrescue/ ddrescue: http://www.gnu.org/software/ddrescue/ddrescue.html Comparison between ddrescue and dd_rescue: http://www.forensicswiki.org/wiki/Ddrescue ddrescue can perform multipass cloning. It clones the easy sectors on the first pass, and attempts the more difficult ones on subsequent passes. It can also clone your drive in reverse, thereby disabling lookahead caching. Ddrescue maintains a log, which means it can resume after an interruption, such as when your drive hangs or goes AWOL. Cloning tools such as Acronis do not understand how to work around bad sectors. This makes them effectively useless. Don't be tempted to use CHKDSK in repair mode. It will most likely exacerbate the file system damage. More info: http://en.wikipedia.org/wiki/Ddrescu...variants_of_dd http://www.cgsecurity.org/wiki/Damaged_Hard_Disk The following is a GNU ddrescue example from Wikipedia: # first, grab most of the error-free areas in a hurry: ddrescue -n /dev/old_disk /dev/new_disk rescued.log # then try to recover as much of the dicey areas as possible: ddrescue -r 1 /dev/old_disk /dev/new_disk rescued.log - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

Wups, sounds likely. If you got a large number of defects, then you damaged the head assembly, no other way to get that outcome from mechanical shock.
