HDD suddenly has bad sectors
Ok. Can I connect this problem hdd up to another comp as a slave drive and
pull data off the problem drive without the problem drive having a working FAT? I have run a DOS hdd utility from seagate on the problem drive and found out that it is a WD drive. Here is the log file of the drive: --------------- SeaTools for DOS v1.09PH --------------- Device 0 is ATA device WDCAC313000R WD-WM6760118569 On Generic PCI ATA Device is 28 Bit Addressed - Max LBA 25429824 ( 13.020 GB ) This drive does not support Security Features SMART Is Supported And ENABLED SMART Has NOT Been Tripped DST Is NOT Supported Logging Feature Set Is NOT Supported POH 0 Drive FAILS Pretest SMART Checks !!

"Jeff Richards" wrote in message ... Scandisk is a file system diagnostic and repair utility, not a disk maintenance utility. If you run Scandisk and ask it to repair the file system while the disk drive itself is still faulty then it will simply compound the problem. Depending on the cause of the problem, it's likely that the more you use the disk the worse the errors will get. You need to get a hard disk drive diagnostic program from the www site of the disk drive manufacturer and use it to determine the extent, and possibly the cause, of the problem. Once you know what you are up against you can develop a recovery plan, such as installing the drive in a different machine and copying all your important data off to a different drive. However, I would guess that the Scandisk attempts at repair, and the length of time that it is taking, has already corrupted the data to the extent that there may be little that is recoverable. Clusters that Scandisk marks as bad are simply removed from the view of the file system. They can be ignored when the disk is formatted, and will re-appear, unless the format process also marks them as bad.. Whether or not they are recovered if you do an image restore depends on the particular restore you are using - some do and some don't. I would expect an 'image' restore to ignore Scandisk's bad sector allocations, however some restore processes that are called 'image' really aren't. However, Scandisk attempts to access the bad sectors may cause the drive's internal logic to flag the sectors as bad. In this case they become permanently marked as bad in the drive's electronics and cannot be recovered. -- Jeff Richards MS MVP (Windows - Shell/User) "SpamMePlease(NOT)" wrote in message ... Hi Have a hdd which has suddenly developed bad sectors/clusters. Currently I cannot boot to windows so I booted to the command prompt and ran a surface scan dos utility with the auto fix switch. This surface scan dos utility has been running day and night for 4 days and has 1200+ bad clusters. What I want to know is whether the bad clusters it is marking as bad clusters will be permanetely marked as such; i.e. the hdd will know not to use this space again even if I try to restore an image of the partition? |

Be careful, the I/O system could be as much at fault here. Mostly failed
RAM not detected by the bios setup. Use the current hard drive manufacturer's software for determining cluster failures, and mapping out failed areas. -- Dave Apathy and denial are close cousins "SpamMePlease(NOT)" wrote in message ...

And the less the drive is accessed until you have the proper tools available
for data recovery, the better. -- Dave Apathy and denial are close cousins "Jeff Richards" wrote in message ... If by that response you mean that the data on the malfunctioning drive is useful to you, then the advice you have received from philo is exactly correct - install a new hard drive so that all your further diagnostic and recovery efforts can continue without any need to write anything to or make any changes to the problem drive. That is the most effective way to maximise your chances of recovering your data. Anything else is a waste of time. -- Jeff Richards MS MVP (Windows - Shell/User) "SpamMePlease(NOT)" wrote in message ... I have only one word to say DATA. "philo" wrote in message ...
