I would just like to thank my77stang (+1 REP) as I have had two Maxtor DiamondMax 22 STM3500320AS drives both with the MX15 firmware which have both been dead for months.
After a few purchases of the Nokia phone cables I finally found one that worked and have fixed both my drives (although one has developed another fault now).
Following the fix, both drives still have all the data and can be accessed again like new!
Other than to say thanks, I have registered here to add some input on the cables I purchased as it's currently not within these pages so hopefully it shall help someone else...
The first cable I bought was from Thailand which contained 5 wires.
Unfortunately, it required a load in the form of a battery or phone before windows would recognise it. It came with no drivers and just seemed more hassle than it was worth... at only Â£2-Â£3 I got back onto eBay and bought another one.
The second CA-42 cable
I bought I made sure was from China.
This one contained just 3 wires.
White = connected to TX on HDD
Yellow = connected to RX on HDD
Green = ground
I found out these designation through trial and error with Hyperterminal by performing a loopback test. For anyone else who didn't know what this entailed, basically you connect 2 of the wires together and type something into Hyperterminal. If when you pressed a key, nothing appeared in the Hyperterminal window, then you didn't have the Tx and Rx cables touching each other. Once these were identified, by process of elimination, the ground was found too.
Also, I followed the YouTube- Seagate 1TB BSY error fix 7200.11 Firmware SD15 ST31000340AS
video provided by user928754 (+1 REP) which was linked previously
and I found it very useful to follow, so thank you for posting that up.
Anyway, thanks to all who've contributed within this thread, you've saved my bacon!
For anyone else reading this and wishing to give it a try, I have subscribed to this thread so shall get emails if people reply with questions that I might be able to help with.
Good luck!Edited by JustBiteMe2k - 2/18/10 at 12:49pm
