You should not use your old identity - it will be disqualified for losing data anyway.
Your held amount will be used to recover lost data to other nodes.
If you have pending payouts, they will be added to your balance, if you would use the same wallet.
often hdd’s doesn’t just fail… they usually just start to get temperamental and make errors.
i’ve had good results with limited transfer speeds from a broken drive to get the data out… in my case i used an ftp server / client to limit the transfer… but anything can work so long as one can limit the speed…
usually a 10-20MB/s should almost always work, and so long as one doesn’t overload the drive it should run fine… most of the time
ofc if the storagenode is DQ then its to late… but so long as the node isn’t DQ it might work…
