Excellent service from Geoff, well recommended. Quick, extremely reasonable and good communications. Recovered our disk with no noticeable loss of recordings. In fact the disk is probably better than before because he added a few extra useful TAPs.

And just in time for Christmas.

Many Thanks.

Hi Mark

Many thanks for the endorsement and confirmation that all is well.

Merry Christmas

Geoff

I have what appears to be one very corrupt TF5800 drive.

I was going to have a look at it with TopfHDRW but I'm worried about the risk of doing more damage, though I assume no writes are performed without user intervention.

However the other question is whether the TDM is likely to result in a better outcome.

The drive is a Samsung SV1604E/OMD 160GB. The names of the recording are there but all at small or zero file sizes. The Toppy has been run, or attempted to be run, in an unstable state (see my other message in General.)

As you surmise, running TopfHDRW on it won't damage the disk unless you say you want to save the changes.

Obviously, what is recoverable on the disk is dependent on how long the disk has been in use after the corruption e.g. a timer may have triggered a recording or you might have timeshift enabled (this lso records to disk). In practice, nearly all the recordings are recoverable using TDM and they also have names related to the recording (TopfHDRW is likely to give them names which give no indication of the content)

Suggest you install GSmartControl (free) on your pc and check the status of the disk (when it is connected to the pc).
Problem areas will be shown in red.


Cheers
Geoff

Thanks Geoff.

Gsmartcontrol gives little away other than to say the drive appears to be there.

To be clear the TV program names were available both via the Archive button with a lot (maybe all) shown also under Bad Files, and via Antares.

The Toppy was always left on so buffering, and no doubt attempts at recording.

TopfHDRW (well TopfHDDoctor as the former fails with an error message) gives:

TopfHDRW seems to be reading the disk so the hardware is probably ok(ish)
When it says "subscript out of range" you can click on Ignore (but it typically will fail immediately with another range error).

TDM should be able to process the disk - it really depends on how much overwriting has been done by the time shifting. Typically, it is only the clusters at the start of the disk that get overwritten. Unfortunately, this is where the file allocation tables are stored (and usually the directory info also); most recordings are typically further up the disk and can be recovered.

Just a quick thanks to Geoff who has fixed the lost recordings.
