There is Drivesavers.com if apps for Apple I noted at https://www.cnet.com/forums/discussions/lost-and-found-or-the-storage-forum-sticky-354911/ don't help.
I have to write again we only lose what we don't backup. If there is no backup, then your data is at risk.
i bought seagate hardisk for my mac , i stored my data in it and now it got corrupted and i am unable to fetch my data as it is not detected by any system any platform.
can anyone help me?
