Deep analyse 48 hours only 50%

#1 Post by pipco » 26 May 2017, 00:24

Hi,

ok, accidentally formatted whole 1.5T drive that had 3 partitions (Guid) for Hackintosh with Chimera efi,
2 partitions had Lion and M-Lion,the third was going to install Sierra, instead of formatting 3rd partition for
Sierra I formatted complete drive. Don't know if this is normal but I'm 48 hours into Deep scan and only 50%
has completed, here is what I have so far:-

48 hours later, is the deeper partition search completed ? Please copy/paste the testdisk.log file content.

HI, thanks for the reply and the program,
as I said in first post this is a Hackintosh drive not a Mac.
It's partitioned into 3 x approximately 3 - 400G (GUID)
with either chameleon or chimera using the EFI as a multi boot drive,
if you could please point me in the right direction as the final results after over 4 days don't look good,
thanks again, pipco

The following partitions may be interesting. Try to recover the 148GB partition first.

No need to do a deeper search, press 'a' to manually add the partition. Set the partition as P(rimary), the other partition using the whole disk as D(eleted).
On next screen, choose Write, confirm, Quit and restart the computer

G'day mate,

ok I've re-analyzed the HD unmounted using 'disk' instead of rdisk,
it reduced the time from 5 days down to 10 hours and looks like it's
picked up partitions of approximately the right size.

I don't know if these are actual partitions or can be recovered but the sizes look very close:-


LVM magic value at 1298024551/0/1

HFS+ magic value at 1300211551/0/1
part_size 499902336
Mac HFS 1300211551 1800113886 499902336
HFS+ blocksize=4096, 255 GB / 238 GiB


HFS+ magic value at 1961017419/0/1
part_size 969003904
Mac HFS 992013517 1961017420 969003904
HFS+ found using backup sector!, 496 GB / 462 GiB


HFS+ magic value at 2624646310/0/1
part_size 663651144
Mac HFS 1960995168 2624646311 663651144
HFS+ found using backup sector!, 339 GB / 316 GiB


HFS+ magic value at 2904818292/0/1
part_size 958094920
Mac HFS 2904818292 3862913211 958094920
HFS+ blocksize=4096, 490 GB / 456 GiB
This partition ends after the disk limits. (start=2904818292, size=958094920, end=3862913211, disk end=2930275055)


HFS magic value at 56065948/0/1
part_size 1124860966
Mac HFS 56065948 1180926913 1124860966 [‡]
HFS blocksize=16777216, 575 GB / 536 GiB


I've attached the log file and am hoping at least one of the partitions can be reinstated,
any help as to how I can proceed would be really appreciated, thanks,,,,

Yours, pipco
