how to erase ssd

My ThinkPad t430 has installed two systems, win7+ubuntu11.10. Due to the needs of the project, 11.10 systems and related environments need to be retained, but also want to install ubuntu12.04, the original hard disk capacity is tight, so bought a 120GB mSATA interface SSD, installed on its ubuntu12.04 64bit, during which encountered a lot of problems.1, new SSD identification problem. Installed on the

Recently bought a 256GB SSD SSD, want to test the write speed, so the following operation.Part of the code:1Gettimeofday (start, NULL);2 intFD = open ("Test1.dat", o_rdwr|o_creat);3 if(FD 0){4printf"Open error!\n");5 return 0;6 }7 //Lseek (FD, 0, seek_set);8 Write (FD, PData, Data_len);9 Close (FD);TenGettimeofday (end, NULL); One A //display elapsed time in US -diff =1000000* (END.TV_S

Last October, Apple updated its newest Mac mini, the new Mac Mini is still a very attractive device for some consumers seeking micro-desktop systems, but its 5400-rpm mechanical hard drive has been hit by a lot of users, and in today's SSDs, the SSD is king. The disadvantage of the mechanical hard drive restricts the Mac mini user experience, but don't worry. Today, PC6 Apple net small make up for you to bring a netizen to provide 2014 of the Mac mini

First of all: The following article is for the use of Windows, because the Std::map erase function of the Windows implementation version is to return a std::map iterator, but the STL standard inside the return value of the function is actually:There are 3 overloads of the Map.erase:void Erase (iterator position);Size_type Erase (const key_type x);void

When I wrote a small example today, I encountered the following problem: I want to traverse a vector, but when some conditions in the traversal process are met, I plan to delete the elements of the composite condition. Use erase to permanently delete the file when deleting the file, and then continue to traverse the file. (in this case, I have seen it on Objective C ++, but I cannot find it. I still remember there is a solution, so you can find a solu

Erase () trap of STL-iterator failure summary, stlerase The following materials are collected from Internet books.Containers in STL are divided into two types by storage method: containers stored in arrays (such as vector and deque), and containers stored in discontinuous nodes (such: list, set, map ). When using the erase method to delete elements, pay attention to some issues.1. list, set, map container

Sequential containers::(vectors and lists and deque)The erase iterator not only invalidates all iterators that point to the deleted element, but also invalidates all iterators after the deleted element, so erase (iter++) cannot be used, but the return value of erase is the next valid iterator, so the correct method is:: For (iter = C.begin (); ITER! = C.end ();)i

The 3rd chapter of library function, which is about the problem of library function, is introduced in this chapter. Using library functions can reduce the difficulty of software development and improve the efficiency of code writing. This section introduces the misuse of the Multiset container erase function.Ad:51cto Net + 12th salon: The beauty of big data-how to drive user experience with dataMisuse of erase
