Hi

I have a couple of disks that appear to have given up.
One reports bad block in the XP system log.

both fail to materialise in my computor or the disk management tool
both appear in device management and report working correctly.
both appear in Hxd and open but no data is seen.

Any suggestions on how to get data off would be welcomed.

Thanks
steve

Try booting off a Linux Live disk and see if will show anything in the data. There is a good utility to do a disk recovery but it can take a long time. ddrescue, which is a Linux utility, you can run it off a boot disk, it will try to clone the bad drive onto a good one (so you need a second drive for this), and will attempt to copy bad areas several times, then will go on to the next sector ignoring bad ones. At some point you will have a clone of the failing drive, hopefully with at least some readable data. This can take a long time to run, I have seen it run for almost a week.

Using the live CD I was able to interrogate the drive easily and identify that one of the drives was still marked as open. LiveCD also suggested mount command syntax to force mount the drive. This worked.
Still yet to look at the other drive.
Thanks for the advice so far hang-the-9

Some data company specialists will highly recommend doing only a one-pass sector by sector clone. because If the HD is imminently physically failing, multi-pass might hasten the HD's physical decline.
