IS there any way to recover data on a corrupted root file? I am using 5.06/0 on win2k reading a file creaated w/ 4.02/0. Here’s result of ctor call:
[ul]root [1] TFile *f = new TFile(“x:/r5_00924.rhit”)
Error in TFile::Init: file x:/r5_00924.rhit is truncated at 27219776 bytes: should be 27219979, trying to recover
Info in TFile::Recover: x:/r5_00924.rhit, recovered key CVoltage:CVoltage at address 727
Info in TFile::Recover: x:/r5_00924.rhit, recovered key CBowl:CBowl at address 2347
Info in TFile::Recover: x:/r5_00924.rhit, recovered key CCalibMass:CCalibMass at address 3314
Warning in TFile::Init: successfully recovered 3 keys

TKey Name = CVoltage, Title = , Cycle = 1
TKey Name = CBowl, Title = , Cycle = 1
TKey Name = CCalibMass, Title = , Cycle = 1
[/ul]The file is supposed to have the following objects:
CVoltage (non-root object)
CBowl (non-root object)
CCalibMass (non-root object)
CEfficiency (non-root object)
CHits (non-root object)
CRunHeader (non-root object)
nth (a TTree object)
There are a bunch of other root objects, but not at the top level…
Thanks!
