Hi: For years i have a Macally PHR-100AC FireWire/USB 2.0 3.5-Inch ATA Hard Drive Enclosure, with no problem until i connected to a PC, hang out, i unplugged and then problem began. My Macbook recognize it, but says this: DISK REPAIR: The Disk "Firewire was not repairable by this computer. It is beaing made available to you with limited functionality. You must back up your data and reformat the disk ASAP:". Well, the thing is that i dont see any data, i double click the disk and it seems like its nothing there. (with File Info it look like i have something more than 180Gb data used) With DISK UTILITY, First Aid, i try to Verify Disk and this error appear: "Filesystem verify or repair failed" Down in red: "Invalid node structure Invalid node structure Volume check failed Error: Filesystem verify or repair failed" I try diskwarrior but does want to do nothing with the firewire.... Any comments??? Thanks a lot!!
