Hi, I’m new to this forum.
Hoping that someone can advise me on a problem with HDD replacement.
I recently acquired a DMR-BWT735EB on Freecycle.
The owner informed me that the unit had become unreliable and sometimes failed to make scheduled recordings. I formatted the HDD, without issue and the unit was functional. I decided to check the integrity of the HDD, so, I removed it from the unit and connected it to my desktop PC. The SMART data revealed reallocated sectors (0448), uncorrectable sectors (0658) and a recommendation of “Caution”.
I decided to replace the HDD with a good tested Seagate ST1000DM003, I had lying around. A few minutes on Google led me to this forum and I followed a procedure posted by jonoro:
Using HxD I copied the data (Offset 0000000 to 0170200) from the original HDD to the new HDD. I then hooked up the new HDD to the 735, powered-up and formatted successfully.
Within 20 seconds of returning to the normal display (BBC1) I get this message:
“Error has occurred. The operation stopped because USB HDD may have been removed without procedure of “USB HDD Disconnection” or there may be a problem with the disc. Press OK. Then this unit will be turned off and start self check and recovery after restart” (See post #15 Alla87 Dec 16 2019).
I press OK, screen goes blank and PLEASE WAIT scrolls across display. This is followed by U61 on the display. The screen then returns to normal display (BBC1) which is obscured by the message:
“Self check and recovery has finished. This unit is turned to off automatically. Please wait. After this unit is turned off press Power to restart”.
After about 1 minute PLEASE WAIT scrolls across the display and the unit turns off.
I then press the Power button. The screen then returns to normal display (BBC1) which is obscured by the message:
“Part of the last recording or copy may be lost due to removal of USB HDD or problem with the disc caused by scratches, dirt or quality of disc. Please use another disc if the disc has a problem. Press OK.”
I press OK and after about 2 minutes the unit suddenly switches off without any warning.
I have made the following observations:
No USB HDD is registered with this unit.
When I return the original HDD to the unit, it formats and I get no error messages.
When I examine the original HDD data, using HxD, starting at offsets 41020, 42020, 43020 and 2042020 I see the following data:
1S1GAA3N…...AM12 TS0100MV00-2C11T26
I think this data is related to the HDD serial no. (S1G1AAN3), firmware (MA21), and part no. (ST1000VM002-1CT162-125). The characters having been transposed/ abbreviated.
When I examine the new HDD (after formatting in 735), at the same offsets, I see exactly the same data. Should it not have changed, after formatting, to something related to the new HDD? (The new HDD is a Seagate Desktop HDD serial no. (Z9A67GEP), firmware (CC43), and part no. (ST1000DM003-1SB102-300)).
Any info or help would be much appreciated.
